BLACK HOLES

Black Holes and Other Dark Matters Marc Kamionkowski of Johns Hopkins University In February 2016, the Laser Interferometer Gravitational Wave Observatory (LIGO) announced discovery of the merger of two black holes, each of which weighed around 30 times the mass of the Sun. In addition to being the first detection of gravitational waves, it was also the first observational evidence of stellar mass black holes above 25 solar masses. Shortly thereafter, it was speculated that these black holes might make up the dark matter that has long been known to exist in galaxies (like our own Milky Way). Dr. Kamionkowski will discuss this possibility and explain why this hypothesis may or may not work.

According to Geek.com, Armchair Astronomers Can Now Visit a Black Hole–In Virtual Reality. In anticipation of the first image of the Milky Way’s supermassive black hole, a team of international researchers built a virtual reality simulation of Sagittarius A*. The VR experience, created as part of the BlackHoleCam project, was published today in the journal Computation Astrophysics and Cosmology. A version is also available to view on YouTube. https://www.geek.com/news/armchair-astronomers-can-now-visit-a-black-hole-in-virtual-reality-1761628/?source http://www.wochit.com This video was produced by YT Wochit News using http://wochit.com

A new model is bringing scientists a step closer to understanding the kinds of light signals produced when two supermassive black holes, which are millions to billions of times the mass of the Sun, spiral toward a collision. For the first time, a new computer simulation that fully incorporates the physical effects of Einstein’s general theory of relativity shows that gas in such systems will glow predominantly in ultraviolet and X-ray light. The new simulation shows three orbits of a pair of supermassive black holes only 40 orbits from merging. The models reveal the light emitted at this stage of the process may be dominated by UV light with some high-energy X-rays, similar to what’s seen in any galaxy with a well-fed supermassive black hole. Three regions of light-emitting gas glow as the black holes merge, all connected by streams of hot gas: a large ring encircling the entire system, called the circumbinary disk, and two smaller ones around each black hole, called mini disks. All these objects emit predominantly UV light. When gas flows into a mini disk at a high rate, the disk’s UV light interacts with each black hole’s corona, a region of high-energy subatomic particles above and below the disk. This interaction produces X-rays. When the accretion rate is lower, UV light dims relative to the X-rays. Based on the simulation, which ran on the National Center for Supercomputing Applications’ Blue Waters supercomputer at the University of Illinois at Urbana-Champaign, the researchers expect X-rays emitted by a near-merger will be brighter and more variable than X-rays seen from single supermassive black holes. The pace of the changes links to both the orbital speed of gas located at the inner edge of the circumbinary disk as well as that of the merging black holes. Credit: NASA Goddard Media Studios

Our perspective from Earth could be distorting our understanding of space. Here’s what you need to know about the theory of AGN unification. What Really Happens When Galaxies Collide - https://youtu.be/eWqETkudZXo Read More: Why It’s Hard to Recognize a Black Hole http://nautil.us/blog/why-its-hard-to-recognize-a-black-hole “If they are all fueled by supermassive black holes, why don’t all AGN look the same? One reason could be our point of view. The theory of AGN unification posits that all AGN have the same basic building blocks (accretion disk, jets, torus); The striking differences we observe, according to this theory, are all due to their orientation in space.” Active Galaxies https://imagine.gsfc.nasa.gov/science/objects/active_galaxies1.html “Active galaxies are galaxies that have a small core of emission embedded at the center of an otherwise typical galaxy. This core is typically highly variable and very bright compared to the rest of the galaxy.” What are active galactic nuclei? https://phys.org/news/2016-11-galactic-nuclei.html “In the 1970s, astronomers became aware of a compact radio source at the center of the Milky Way Galaxy – which they named Sagittarius A. After many decades of observation and mounting evidence, it was theorized that the source of these radio emissions was in fact a supermassive black hole (SMBH).” ____________________ Elements is more than just a science show.

Astronomers from the Swiss Federal Institute of Technology in Zurich have discovered several pairs of supermassive black holes located at the center of galaxies which are currently colliding. Digital Trends reports the scientists were examining what happens when two galaxies join to become one. They were able to identify two supermassive black holes at the center of the two original galaxies which will eventually coalesce into one large black hole. Overall, the findings suggest that more than 17% of the galaxies studied had a pair of black holes at their center which were approaching one another. https://www.digitaltrends.com/cool-tech/black-holes-colliding-galaxies/ http://www.wochit.com This video was produced by YT Wochit News using http://wochit.com

ESO’s exquisitely sensitive GRAVITY instrument has added further evidence to the long-standing assumption that a supermassive black hole lurks in the centre of the Milky Way. New observations show clumps of gas swirling around at about 30% of the speed of light on a circular orbit just outside a four million solar mass black hole — the first time material has been observed orbiting close to the point of no return, and the most detailed observations yet of material orbiting this close to a black hole.

Considering that they are so dense that their gravity won’t let anything out, not even light, you can imagine that well… they are pretty black. Couple that with how black space is and it’s easy to conclude that black holes are hard to find. Well this week, astronomers have found an new technique for finding them.

A new model is bringing scientists a step closer to understanding the kinds of light signals produced when two supermassive black holes, which are millions to billions of times the mass of the Sun, spiral toward a collision. For the first time, a new computer simulation that fully incorporates the physical effects of Einstein's general theory of relativity shows that gas in such systems will glow predominantly in ultraviolet and X-ray light. Just about every galaxy the size of our own Milky Way or larger contains a monster black hole at its center. Observations show galaxy mergers occur frequently in the universe, but so far no one has seen a merger of these giant black holes. Scientists have detected merging stellar-mass black holes -- which range from around three to several dozen solar masses -- using the National Science Foundation's Laser Interferometer Gravitational-Wave Observatory (LIGO). Gravitational waves are space-time ripples traveling at the speed of light. They are created when massive orbiting objects like black holes and neutron stars spiral together and merge. Supermassive mergers will be much more difficult to find than their stellar-mass cousins. One reason ground-based observatories can't detect gravitational waves from these events is because Earth itself is too noisy, shaking from seismic vibrations and gravitational changes from atmospheric disturbances. The detectors must be in space, like the Laser Interferometer Space Antenna (LISA) led by ESA (the European Space Agency) and planned for launch in the 2030s. But supermassive binaries nearing collision may have one thing stellar-mass binaries lack -- a gas-rich environment. Scientists suspect the supernova explosion that creates a stellar black hole also blows away most of the surrounding gas. The black hole consumes what little remains so quickly there isn't much left to glow when the merger happens. Supermassive binaries, on the other hand, result from galaxy mergers. Each supersized black hole brings along an entourage of gas and dust clouds, stars and planets. Scientists think a galaxy collision propels much of this material toward the central black holes, which consume it on a time scale similar to that needed for the binary to merge. As the black holes near, magnetic and gravitational forces heat the remaining gas, producing light astronomers should be able to see. The new simulation shows three orbits of a pair of supermassive black holes only 40 orbits from merging. The models reveal the light emitted at this stage of the process may be dominated by UV light with some high-energy X-rays, similar to what's seen in any galaxy with a well-fed supermassive black hole. Three regions of light-emitting gas glow as the black holes merge, all connected by streams of hot gas: a large ring encircling the entire system, called the circumbinary disk, and two smaller ones around each black hole, called mini disks. All these objects emit predominantly UV light. When gas flows into a mini disk at a high rate, the disk's UV light interacts with each black hole's corona, a region of high-energy subatomic particles above and below the disk. This interaction produces X-rays. When the accretion rate is lower, UV light dims relative to the X-rays. Based on the simulation, the researchers expect X-rays emitted by a near-merger will be brighter and more variable than X-rays seen from single supermassive black holes. The pace of the changes links to both the orbital speed of gas located at the inner edge of the circumbinary disk as well as that of the merging black holes. The simulation ran on the National Center for Supercomputing Applications' Blue Waters supercomputer at the University of Illinois at Urbana-Champaign. Modeling three orbits of the system took 46 days on 9,600 computing cores.

This 360-degree video places the viewer in the middle of two circling supermassive black holes. The simulation shows how the black holes distort the starry background and capture light, producing black hole silhouettes. A distinctive feature called a photon ring outlines the black holes. The video represents a 46 minute orbital period. This corresponds to a binary with a total mass 1 million times the Sun's mass. The black holes would be separated by about 18.6 million miles (30 million kilometers). The background is a mosaic of the images covering the entire sky as observed by ESA's Gaia mission.

For the first time ever, scientists using Fermi Gamma-ray Space Telescope have found the source of a high-energy neutrino from outside our galaxy. This neutrino travelled 3.7 billion years at nearly light speed before being detected on Earth -- farther than any other neutrino we know the origin of. High-energy neutrinos are hard-to-catch particles that scientists think are created by the most powerful events in the cosmos, like galaxy mergers and material falling onto supermassive black holes. They travel a whisker shy of the speed of light and rarely interact with other matter, so they can travel unimpeded across billions of light-years. The IceCube Neutrino Observatory at the South Pole detected signs of a neutrino striking the Antarctic ice with an energy of about 300 trillion electron volts -- more than 45 times the energy achievable in the most powerful particle accelerator on Earth. This high energy strongly suggested that the neutrino had to be from beyond our solar system. Backtracking the path through IceCube indicated where in the sky the neutrino came from, and automated alerts notified astronomers around the globe to search this region for flares or outbursts that could be associated with the event. Data from Fermi’s Large Area Telescope revealed enhanced gamma-ray emission from a well-known active galaxy at the time the neutrino arrived. This active galaxy is a type called a blazar, where a supermassive black hole with millions to billions of times the Sun’s mass that blasts particle jets outward in opposite directions at nearly the speed of light. Blazars are especially bright and active because one of these jets happens to point almost directly toward Earth. Fermi showed that at the time of the neutrino detection, the blazar TXS 0506+056 was the most active it had been in a decade. The discovery is a giant leap forward in a growing field called multimessenger astronomy, where new cosmic signals like neutrinos and gravitational waves are definitively linked to sources that emit light.

Let’s figure this out. If black holes exist – which, apparently, they do – they contradict other theories in physics as sacred as general relativity. They cause all sorts of problems with quantum theory, which we’ve talked about and will review in a sec. But they also present an apparent conflict with the notion of entropy and the second law of thermodynamics. It was while pondering that conflict that Jacob Bekenstein realized an incredible connection between black holes and thermodynamics. His insight launched an entire new way of thinking about the universe in terms of information theory, and ultimately led to the holographic principle. Which I promise we’re getting to and we’re almost there. We just need to understand string theory first and to understand that, you’re going need to know about why Black Holes contain most of the universe’s entropy.

According to Gizmodo, scientists now believe Black Holes might temporarily be able to bring dead stars back to life. In what has been described as a “brief zombie awakening,” a team of scientists studying white dwarfs - small dense objects formed when bigger stars run out of fuel - determined that black holes could theoretically reignite dead stars in a supernova like explosion. Scientist went on to say that the results of reigniting these dead stars would be the generation and release of heavier elements into the cosmos. https://gizmodo.com/black-holes-might-temporarily-bring-dead-stars-back-to-1828715319 http://www.wochit.com This video was produced by YT Wochit News using http://wochit.com

A group of scientists recently announced in the Royal Astronomical Society they discovered a supermassive black hole in a tiny galaxy.

According to a report by Geek.com, the Rochester Institute of Technology found evidence of massive black holes hiding at the often overlooked outer edges of spiral galaxies. Using data from the Lick Observatory Supernova Search the team discovered a comparable number of black holes in the outskirts of spiral galaxies as in dwarf/satellite galaxies. Study author Sukanya Chakrabarti said, "If these core-collapse supernovae are the predecessors to the binary black holes detected by LIGO, then what we’ve found is a reliable method of identifying the host galaxies of LIGO sources." She went on to explain, “Because these black holes have an electromagnetic counterpart at an earlier stage in their life. we can pinpoint their location in the sky and watch for massive black holes.” https://www.geek.com/news/scientists-uncover-new-hangout-for-black-holes-1747509/?source http://www.wochit.com This video was produced by YT Wochit News using http://wochit.com

Don’t get me wrong; the math is complicated. But the objects themselves are simple. In fact every black hole in the universe, no matter how it formed or what happened to it afterwards, can be perfectly described with only three properties. Those properties are mass, angular momentum, and electric charge. Or at least this is the proposition behind the famous no-hair conjecture, or no-hair theorem.

The spectacular merger of two neutron stars that generated gravitational waves announced last fall likely did something else: birthed a black hole. This newly spawned black hole would be the lowest mass black hole ever found. A new study analyzed data from NASA's Chandra X-ray Observatory taken in the days, weeks, and months after the detection of gravitational waves by the Laser Interferometer Gravitational Wave Observatory, or LIGO, and gamma rays by NASA's Fermi mission on August 17, 2017. While nearly every telescope at professional astronomers' disposal observed this source, known officially as GW170817, X-rays from Chandra are critical for understanding what happened after the two neutron stars collided. From the LIGO data astronomers have a good estimate that the mass of the object resulting from the neutron star merger is about 2.7 times the mass of the Sun. This puts it on a tightrope of identity, implying it is either the most massive neutron star ever found or the lowest mass black hole ever found. The previous record holders for the latter are no less than about four or five times the Sun's mass. The Chandra observations are telling, not only for what they revealed, but also for what they did not. If the neutron stars merged and formed a heavier neutron star, then astronomers would expect it to spin rapidly and generate a very strong magnetic field. This, in turn, would have created an expanding bubble of high-energy particles that would result in bright X-ray emission. Instead, the Chandra data show levels of X-rays that are a factor of a few to several hundred times lower than expected for a rapidly spinning, merged neutron star and the associated bubble of high-energy particles, implying a black hole likely formed instead.

Stephen Hawking was one of the greatest scientific and analytical minds of our time, says NASA's Michelle Thaller. She posits that Hawking might be one of the parents of an entirely new school of physics because he was working on some incredible stuff—concerning quantum entaglement— right before he died. He was even humble enough to go back to his old work about black holes and rethink his hypotheses based on new information. Not many great minds would do that, she says, relaying just one of the reasons Stephen Hawking will be so deeply missed. You can follow Michelle Thaller on Twitter at @mlthaller. Read more at BigThink.com: http://bigthink.com/videos/michelle-thaller-ask-a-nasa-astronomer-how-did-stephen-hawking-change-the-world Follow Big Think here: YouTube: http://goo.gl/CPTsV5 Facebook: https://www.facebook.com/BigThinkdotcom Twitter: https://twitter.com/bigthink Michelle Thaller: Yes Jeremy, a lot of us were really sad with the passing of Stephen Hawking. He was definitely an inspiration. He was one of the most brilliant theoretical physicists in the world, and of course he overcame this incredible disability, his life was very difficult and very dramatic and I for one am really going to miss having him around. And I certainly miss him as a scientist too. He made some incredible contributions. Now, Stephen Hawking was something that we call a theoretical physicist, and what that means is that people use the mathematics of physics to explore areas of the universe that we can’t get to very easily. For example, conditions right after the Big Bang the beginning of the universe, what were things like when the universe was a fraction of a second old? That’s not something we can create very easily in a laboratory or any place we can go to, but we can use our mathematics to predict what that would have been like and then test our assumptions based on how the universe changed over time. And one of the places that is also very difficult to go to is, could we explore a black hole? And this is what Stephen Hawking was best known for. Now, black holes are massive objects they’re made from collapsed dead stars, and the nearest black hole to us is about 3000 light years away. That one is not particularly large, it’s only a couple times the mass of the sun. The biggest black hole that’s in our galaxy is about four million times the mass of the sun and that actually sits right in the heart of the Milky Way Galaxy. And right now you and I are actually orbiting that giant black hole at half a million miles an hour. These are incredibly exotic objects. The reason we call them black holes is that the gravity is so intense it can suck in everything, including light. Not even light, going through space freely at the speed of light, can escape a black hole, so talk about dramatic exotic objects that are difficult to do experiments on. Stephen Hawking laid down some of our basic understanding of how a black hole works. And one of the things he actually did was he even predicted that black holes can die. You would think that a collapsed star that forms a bottomless pit of gravity would exist forever, but Stephen Hawking used the laws of quantum mechanics and something called thermodynamics, how heat behaves in the universe, to prove that maybe black holes can evaporate over time. And of course, that’s a hugely significant thing. One of the reasons I think it’s very unfortunate he died is we’re actually right on the cusp of being able to do actual experiments with black holes. And I know that sounds like a strange thing to say, but there are some particle accelerators, I mean specifically the Large Hadron Collider, which is in Europe, that are about to get to high enough energies they’re going to smash particles together so hard that so much energy is generated they might be able to make tiny little black holes. And by the way, this is entirely safe. Don’t worry about it at all. Stephen Hawking showed us that black holes evaporate, they actually die away and the smaller a black hole is the faster this happens. So these little black holes—we’ll probably be lucky if we can detect them, they’re going to die in millionths of a second. And the Large Hadron Collider gets nowhere up to the energy of natural events all around us. Right now there are high energy particles slamming into our atmosphere a couple miles above our heads, and they are many, many hundreds of times the energy that the Large Hadron Collider will ever be able to get up to. So I am saying actually that there are probably tiny little black holes forming all around us, they evaporate away so quickly they’re very hard to detect. Stephen Hawking predicted the exact energy that black holes give off when they evaporate, and it may be that in just a few years time we’re going to observe that in a particle accelerator and realize he was right.

Astronomers at the Australian National University recently announced the discovery of a supermassive black hole thought to have the mass of 20 billion suns.

Supermassive Black Hole Studies with the Large Synoptic Survey Telescope (LSST) - 2018 Remote talk given by W. Niel Brandt (Penn State) to astronomers in the Brazilian Inter-institutional Laboratory for e-Astronomy (LIneA) on 2018 May 3. This talk represents some of the work done by the LSST Science Collaboration (SC) on Active Galactic Nuclei (AGNs). This talk has overlap with Brandt's talk of 2016 Dec 9 on AGN science with LSST (also on YouTube). However, this talk is more focused on the operations of the AGN SC and less focused on detailed science issues. Furthermore, it been updated to reflect new developments from 2016-2018. The talk outline is the following: * Quick review of the LSST surveys * The LSST AGN SC and its plans * AGN selection with LSST and multiwavelength data * Examples of exciting science investigations

Join +Fraser Cain and +Pamela Gay for a live episode of Astronomy Cast. We'll record our 30-minute show, and then stay tuned for them to answer questions! Another update episode, this time we look at what's new and changed in the research of black holes. And it's here that we find a lot of substantial new discoveries in the field, so much has been discovered since we first covered black holes a decade ago.

Shep Doeleman, Smithsonian Astrophysical Observatory, Astronomer & Director, Event Horizon Telescope Project Black holes are the most exotic objects thought to exist in the universe, but no one has ever seen one. In this talk, Dr. Shep Doeleman, astronomer at the Smithsonian Astrophysical Observatory, will explore the evidence for black holes, and describe an effort to link radio dishes around the world to form an Earth-sized virtual telescope that can capture the first images of the supermassive black hole at the center of the Milky Way.

In places of extreme density like the dead core of a massive star, space and time could be dragged inwards to create a hole in the universe: a boundary in spacetime called an event horizon that could be entered, but from beyond which nothing could return. Once formed, there was nothing in theory or imagination that could bring material consumed back to the outside universe. These black holes should exist forever – only growing, never shrinking.

Scientists are attempting to model some of the most powerful explosions in the universe by miniaturizing them into lab experiments. A team used the intense Gemini laser at the Rutherford Appleton Laboratory in the UK, with a special setup for studying what’s called an “electron-positron plasma beam,” or EPB. These beams seem to be creating strong, long-lasting magnetic fields. Scientists were able to observe, for the first time, some of the key phenomena that play a major role in the generation of gamma ray bursts, such as the self-generation of magnetic fields that lasted for a long time. In the universe, Gamma Ray Bursts occur with supernovae, or when massive stas explode. They are also caused by black holes. https://gizmodo.com/scientists-create-miniature-gamma-ray-bursts-to-study-b-1822115741 http://www.wochit.com This video was produced by YT Wochit News using http://wochit.com

Astronomers using ESO’s MUSE instrument on the Very Large Telescope in Chile have discovered a star in the cluster NGC 3201 that is behaving very strangely. It appears to be orbiting an invisible black hole with about four times the mass of the Sun — the first such inactive stellar-mass black hole found in a globular cluster. This important discovery impacts on our understanding of the formation of these star clusters, black holes, and the origins of gravitational wave events. This short ESOcast takes a look at this discovery and its significance. The video is available in 4K UHD.

Astronomers may be a step closer to solving one of the greatest mysteries in astrophysics – which came first the galaxy – or the supermassive black hole at its centre. The problem is do galaxies form first from the accumulation of stars, globular clusters, and molecular gas and dust clouds -- with densities at the galactic centre eventually becoming so high it forms a black hole. *Supermassive black hole stellar factory Astronomers have discovered 11 newly formed infant protostars within three light years of the supermassive black hole at the centre of our galaxy. Black holes generate powerful gravitational tidal forces and intense ultraviolet and X-ray radiation – environments far more conducive to destroying stars rather than creating them. *Mars may not be as dry as it seems A new study suggests water on Mars is being absorbed by the red planet’s rocks like a sponge. The findings reported in the journal Nature suggest that Martian basalt rocks can hold up to 25 percent more water than similar basalts on Earth. *SpaceX to launch Falcon Heavy shortly After more than 12 years of planning and development Space X is finally getting ready to fly its new Falcon Heavy launch vehicle. The 70-metre-tall reusable rocket is based around three Falcon 9 common booster core stages -- mounted side by side in a similar fashion to the Delta 4 heavy -- from which it will take the title as the world’s most powerful operational launch vehicle.

My twitter: https://twitter.com/Dreksler_Astral As of right now we are just not in ability to reach black holes, but will we ever even be in ability to visit black holes, and what would happened if we entered them? In this video it talk about just that. Intro, outro and many other clips in the video are made with Space Engine. Music: At the Foot of the Sphinx - Twin Musicom http://www.twinmusicom.org/

While we have all these different types or classifications of black holes, they all have one particular thing in common: they can all collide and merge. In this video, we discuss different possibilities of black holes colliding and merging and look in detail on what is going on. ►Click here to subscribe: https://www.youtube.com/channel/UCB0fFWQLZ2oj-FaoDUG_wow?sub_confirmation=1 ►Written, Produced & Narrated by: David ►Share this video: https://youtu.be/03MtDOFSxPo Music: “Cylinder Five” by Chris Zabriskie

Learn all about black holes with this fun and informative black hole song for kids! Packed with black hole facts, The Black Hole Song will teach you all about the three different types of black holes, how black holes form, and more. Enjoy! For more music and information, visit http://sillyschoolsongs.com Lyrics: Black hole, a region in space Where gravity is so strong, nothing can escape Black hole, you know that place Where matter is squeezed in a tiny space Black hole, a region in space Where stars collapse and fade away Black hole, you know that place Where matter disappears without a trace Ever wonder what happens, when a star collapses? A black hole! Gravity starts pulling, and all the matter gets trapped in, never to be seen again! Like water going down the drain, when you pull the plug in the tub it's insane How a black hole pulls all the matter around Into a region of space that can't be found A giant star casts out its outer layers Leaving the core, which collapses in on itself And forms a black hole Black hole, a region in space Where gravity is so strong, nothing can escape Black hole, you know that place Where matter is squeezed in a tiny space Black hole, a region in space Where stars collapse and fade away Black hole, you know that place Where matter disappears without a trace There are three types of black holes: Stellar and supermassive and miniature (Whoa!) So a black hole can be small? As tiny as one single atom (That's all??!??) Yeah! But they can be really big too! Supermassive black holes are the ones that are super-huge And then stellar black holes are the ones That come from dying stars much bigger than our Sun Sagittarius A is a supermassive black hole in the middle of the Milky Way We will never reach it, because we are too far away Black hole, a region in space Where gravity is so strong, nothing can escape Black hole, you know that place Where matter is squeezed in a tiny space Black hole, a region in space Where stars collapse and fade away Black hole, you know that place Where matter disappears without a trace Copyright 2018 Silly School Songs.

In April of 2017, astronomers from the Event Horizon Telescope team collected the data needed to form the first real picture of a black hole and very soon they will have analyzed all the data and have the first real picture of a black hole. In this video, we discuss the latest update about taking the first picture of a black hole. ►Click here to subscribe: https://www.youtube.com/channel/UCB0fFWQLZ2oj-FaoDUG_wow?sub_confirmation=1 ►Written, Produced & Narrated by: David ►Share this video: https://youtu.be/EupRWFQJ0bw Music: “Cylinder Five” by Chris Zabriskie

The Schwarzschild radius decides the fate of every black hole in the universe. In this video, we will discuss the two ways of forming a black hole, while also discussing the Schwarzschild radius. ►Click here to subscribe: https://www.youtube.com/channel/UCB0fFWQLZ2oj-FaoDUG_wow?sub_confirmation=1 ►Hosted by: David ►Share this video: https://youtu.be/iQQseekn1zc If you want to read more: https://www.britannica.com/science/Schwarzschild-radius http://www.pbs.org/wgbh/nova/blogs/physics/2011/12/the-schwarzschild-radius-natures-breaking-point/ http://hyperphysics.phy-astr.gsu.edu/hbase/Astro/blkhol.html http://astronomy.swin.edu.au/cosmos/S/Schwarzschild+Radius https://en.wikipedia.org/wiki/Schwarzschild_radius Music: “Cylinder Five” by Chris Zabriskie

A study published Dec. 7 in Nature explains a newfound supermassive black hole 800 million times the mass of the sun could shed light on how the universe formed.

The quasar is around 800 million times the mass of our sun. Learn more about this story at www.newsy.com/74192/ Find more videos like this at www.newsy.com Follow Newsy on Facebook: www.facebook.com/newsyvideos Follow Newsy on Twitter: www.twitter.com/newsyvideos

How can it have a speed when the singularity has zero radius? All of its mass is concentrated into zero volume, right? 4:57 RockawayCCW: Just curious, what's the maximum speed that a spacecraft could achieve by slingshotting around the planets in our Solar System? 6:39 M M: Great video Fraser. Is robbing orbital speed from a planet always done with the spacecraft coming from behind it? Could we slow down if we can from the front? 8:09 Chad Baptiste: Oh man! I just thought of a dope question! Hopefully it makes it into your next QA. What resolution of detail would the Hubble Telescope be able to pick up were it pointed to Earth? Is it like Google Maps detail, or CSI's "zoom and enhance!" detail? 9:40 jonfarray: Hi Fraser, I'm awesome inspired by your QAs. I have a Q that I would love you and your communities thoughts on. As the only known observers, what are we? Are we bags of meat? Bags of star dust? A body with a brain? A brain with a body? A spirit in a vessel? A single organism or a sentient community of organisms? I'm trying to keep my question short, but I guess I'm asking, what are we and what is the meaning of life please? Could it be to the observer? Thanks! 12:01 Grimbot2: If the Moon could be safely placed on Earth's surface, what would happen? Would it roll across the surface as the Earth rotates or would it sink through Earth's crust? 13:14 Paul Clifford: "head over to Patreon" is mandatory in every YouTube video now huh? 15:31 Ivaca Pavic: Why do you always say "in pretty much" every black hole? Does that mean there are galaxies detected without supermassive black holes in the center? What holds those galaxies together then? 16:28 khh1960: When using the transit method to detect exoplanets, how do they determine the size and orbital distance of the planets just by the amount of lost luminosity? 17:58 M.Otto: Wouldn't a water shield a few meters thick be cheaper 19:36 joethepro36: Glad to hear it, without moon landings, Mars is a pipedream. The only question I have is if the Moon is suitable as a staging base? What do you think Fraser?

What does a black hole look like? No one knows for sure. Artists make their images based on what physicists think they look like. But that could be about to change.

The findings indicate these intense plasma streams are charged within 30 thousand kilometres of the black hole itself. *Mars 2020 Rover will have 23 eyes NASA says improvements in camera technology mean its next rover to Mars will have no fewer than 23 cameras, to create sweeping panoramas, reveal obstacles, study the atmosphere, and assist science instruments. *Rare Mariner’s astrolabe discovered Marine archaeologists have recovered a rare Mariner’s Astrolabe in a shipwreck off the coast of Oman. The astrolabe -- stamped with the Portuguese royal coat of arms -- was found in the wreckage of the 500-year-old Portuguese ship Esmeralda -- part of a fleet of 20 vessels under the command of the explorer Vasco da Gama who in 1498 discovered a direct route from Europe to India. *Strange auroral activity discovered on Jupiter It’s been discovered that Jupiter's intense northern and southern auroral lights pulse independently of each other. The findings indicate that very high-energy X-ray emissions at Jupiter's south pole consistently pulse every 11 minutes. However, those at the Jovian north pole are erratic. *November Skywatch We check out the celestial sphere for November on Skywatch. And just like October -- November see’s three meteor showers -- November Orionids, the Taurids, and the Leonids. *The Science Report Atmospheric carbon dioxide levels have now risen to 403.3 parts per million – its highest level in over 800,000 years. Links between some acid reflux drugs and stomach cancer. Migration not murder was the most likely cause for the disappearance of the Neanderthals. New study on the origins of dingos.
