What would it take to make that leap? And where would we get enough energy to power that civilization? Fabio Pacucci explores the possibility of harnessing energy from a black hole to power a galactic civilization. Lesson by Fabio Pacucci, directed by TOTEM Studio.

Why do some giant black holes blast out jets, or beams, of material and others do not? Researchers looked at over 700 rapidly growing supermassive black holes (called "quasars") to find out. Rapid spin is needed for a powerful jet, but not all rapidly spinning black holes have powerful jets. A second factor may be needed: a region of diffuse hot gas threaded with strong magnetic fields that only some black hole systems have. The new study draws parallels between these giant black holes and those that weigh less than a hundred times the mass of the Sun. The new research combined data from NASA's Chandra X-ray Observatory and other telescopes.

A year in the life of M87*, the supermassive black hole in the galaxy M87. The first part shows complicated simulations of the hot material orbiting the black hole using the math of General Relativity and the behavior of plasma. At 92 days the simulations are blurred to show how it would look to the Event Horizon Telescope. The gray bar that appears points toward the average position of the bright spots in the ring. The scale bar shows 40 microarseconds, a very tiny angle on the sky; the ring is about 100 billion kilometers across and 55 million light years from Earth. Credit: G. Wong, B. Prather, Ch. Gammie, M.

Scientists have observed the heaviest black hole merger ever found. On May 21, 2019, three telescopes on Earth received powerful gravitational waves far away from the depths of space. The signal coming from the event known as GW190521 lasted just one-tenth of a second. It turns out they have witnessed what may be the most massive black hole merger ever.

Two black holes, with masses 85 and 66 times the Sun, merged into an intermediate mass black hole 142 solar masses designated GW190521. The merger was detected by the LIGO-Virgo gravitational wave collaboration. This black hole merger is considered to be "impossible" because at least one of the two black holes that merged couldn't have formed in a supernova. Instead, they belong in the "pair instability mass gap" of black holes and must have merged in a prior generation in a cluster or perhaps in a quasar's accretion disk. 00:00 Start 05:07 the GW190521 signal 09:11 the black hole mass gap problem 11:38 Solutions to mass gap problem 14:08 Alternative scenarios 16:27 Future detections 17:45 Blinkist 19:40 Patreon thanks 🔔 Subscribe for more: https://www.youtube.com/christianready?sub_confirmation=1 🖖 Share this video with a fellow space traveler: https://youtu.be/rIsGM2xkjHg 🔴 Watch my most recent upload: https://goo.gl/QbRcE2 🚀 Help me improve the channel by joining the community on Patreon https://patreon.com/launchpadastro 🚀 Check out Launch Pad merchandise! https://teespring.com/stores/launchpadastro Disclaimer: Some of these links go to one of my websites and some are affiliate links where I'll earn a small commission if you make a purchase at no additional cost to you. 🧭 References: LIGO Science Release: GW190521: A Binary Black Hole Merger with a Total Mass of 150 Msun (published in Physical Review Letters): https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.125.101102 Properties and astrophysical implications of the 150 Msun binary black hole merger GW190521: https://iopscience.iop.org/article/10.3847/2041-8213/aba493 GW190521 parameter estimation samples and figure data https://dcc.ligo.org/LIGO-P2000158/public A Candidate Electromagnetic Counterpart to the Binary Black Hole Merger Gravitational Wave Event S190521g.

Astronomers have discovered one type of growing supermassive black hole masquerading as another, thanks to a suite of telescopes including NASA's Chandra X-ray Observatory. The true identity of these black holes helps solve a long-running mystery in astrophysics. The misidentified black holes are from a survey known as the Chandra Deep Field-South, which is the deepest X-ray image ever taken. Supermassive black holes grow by pulling in surrounding material, which is heated and produces radiation at a wide range of wavelengths including X-rays. Many astronomers think this growth includes a phase, which happened billions of years ago, when a dense cocoon of dust and gas covers most black holes. These cocoons of material are the fuel source that enables the black hole to grow and generate radiation. Based on the current picture held by astronomers many black holes immersed in such a cocoon should exist. However, this type of growing black hole is notoriously difficult to find, and until now the observed number has fallen short of predictions — even in the deepest images. Now a team of astronomers has discovered 28 black holes that were previously misidentified in the Chandra Deep Field-South. By showing that there are this many missed black holes in this small patch of sky, researchers can estimate how many others there might be across the Universe. These results are important for theoretical models estimating the number of black holes in the universe and their growth rates, including those with different amounts of obscuration. Scientists design these models to explain a uniform glow in X-rays across the sky called the "X-ray background," first discovered in the 1960s. Since then, astronomers have used Chandra and other telescopes to bring the X-ray background into focus and show that most of the glow comes from individual growing black holes. This newest discovery involves understanding the nature of the objects that have been some of the last to be resolved.

The mind-blowing science of black holes Watch the newest video from Big Think: https://bigth.ink/NewVideo Learn skills from the world's top minds at Big Think Edge: https://bigth.ink/Edge ---------------------------------------------------------------------------------- When it comes to black holes, science simultaneously knows so much and so little, which is why they are so fascinating. Focusing on what we do know, this group of astronomers, educators, and physicists share some of the most incredible facts about the powerful and mysterious objects. A black hole is so massive that light (and anything else it swallows) can't escape, says Bill Nye. You can't see a black hole, theoretical physicists Michio Kaku and Christophe Galfard explain, because it is too dark. What you can see, however, is the distortion of light around it caused by its extreme gravity. Explaining one unsettling concept from astrophysics called spaghettification, astronomer Michelle Thaller says that "If you got close to a black hole there would be tides over your body that small that would rip you apart into basically a strand of spaghetti that would fall down the black hole." ---------------------------------------------------------------------------------- TRANSCRIPT: MICHIO KAKU: First we think that out of the Big Bang came dark matter, invisible matter. If I held dark matter in my hand it would literally ooze its way right though my fingers, go right to the center of the Earth, go to China and then go back and forth between China and my hand. That's dark matter. We think that dark matter began to clump first because of gravity. Then matter was attracted to the clumpiness creating the super massive black hole and then later the galaxy itself began to form. We have computer simulations about this, but still the relationship is not yet clear. Now remember, stars. We know almost everything about stellar evolution. That's because the pentagon has given us physicists billions of dollars to model hydrogen bombs, and a star is nothing but a hydrogen bomb. However, a galaxy consists of over a hundred billion stars so it's much more difficult to tell which came first, the black hole or the galaxy itself. BILL NYE: The way I like to describe a black hole. It's a star. A black hole is a star. Now when you and I think of stars we think about the sun which is giving off all this light. But the other thing about the sun to keep in mind is it has a lot of gravity because it's huge. One of Einstein's discoveries, Albert Einstein's discoveries was that gravity changes the path of light. It can bend light. It's just not in our everyday experience. To measure it we usually find objects way out in space and we have known brightness and we see where we think they're going to be and then where they really appear to be and then we infer or figure out that they're not where we thought they were going to be because gravity bent the beam of light. It's amazing. Anyway, so a black hole is a star so massive that not even light can escape from it. MICHELLE THALLER: What you're looking at is something called the shadow of a black hole. Now, black holes tend to have material orbiting around them. Black holes have a lot of gravity and gas begins to fall in towards the black hole and it begins to spin up into a disk around the black hole. And as that gas gets closer and closer to the black hole its accelerated faster and faster. And so in this disc of gas some of it is traveling very close to the speed of light. You have a lot of friction. You have lots of things rubbing up against each other at very high speeds and incredible amounts of heat and light are generated in this disk. So black holes usually are surrounded by disks of very, very bright, very hot material and that's how we find them. Black holes themselves give off no radiation at all. Any light gets absorbed into the black hole and when I say light I mean every possible form of light from gamma rays, x-rays, infrared light that we think of as heat, radio waves. Nothing comes out of a black hole at all. So what you're looking at in this image is the black hole is sort of framed by this bright ring. And that bright ring is this hot material that's orbiting around the black hole. One of the first things you'd say well okay, it's really kind of a wonderful stroke of luck that the particular black hole we're looking at the ring was right face onto us. You see this bright ring exactly around the black hole. And, in fact, that's probably not the case. The disc of material could be at many different orientations around the black hole. Light itself has no mass. Light should not be attracted by gravity, right. I mean gravity is the force between two things that have mass. Light has no mass. It just flies straight through space...

Black holes are the universe at its most extreme: matter and energy crunched so small they literally exit the known universe. Scientists are beginning to suspect that these monsters have a powerful impact on galaxies, solar systems and space-time itself. And now, researchers are finally getting a grip on these black holes with a new generation of high-tech laser systems and advanced telescopes in space. ---- This channel offers you full episodes of high quality documentaries.
