DOCUMENTARIES

Into the Unknown tells the story of the building of NASA’s James Webb Space Telescope – a revolutionary observatory, 100 times more powerful and the scientific successor to the Hubble Telescope. When launched, Webb will reveal a universe we have never seen before and is poised to answer questions that have intrigued us for thousands of years: How did the universe begin? Where did we come from? Are we alone? Armed with dynamic scenes of construction, fascinating conversations with scientists and engineers and stunning visuals, Into the Unknown offers an in-depth look at one of the most daring scientific missions ever attempted. A story for all ages, this film captures the wonder of the cosmos and the timeless human desire to understand our place within the universe. The Northrop Grumman Foundation, in partnership with filmmaker Nathaniel Kahn, developed this documentary as a resource for teachers, students and space enthusiasts around the world to enjoy.

Part 1 looks at geopolitical developments 50 years from now. Climate concerns, energy issues, peace and the race for weapons technology will dominate international headlines. We’ll take a scientific look at these topics and add a close-up examine the future of nanotechnology and solar energy, all of which will provide the basis of the dramatic scenes. Part 2 concentrates on the future of the human body. The effect of medical progress on the body will dramatically change daily life, but this will be compounded by other technological innovations. “Intelligent” clothing and surroundings will serve to constantly monitor a person’s health and well-being in real time. Micro-chips and sensors will be ubiquitous in all kinds of products and will keep just about everything around us online at all times. Intelligent jackets that monitor important vital signs like respiration and pulse already exist as prototypes. Their data could easily be transmitted via a wireless signal, permitting the wearer to be located immediately in case of an emergency. The elderly, the infirmed and even children could be the first to benefit from this invention. In our dramatic story, protagonist Alain Dega is seriously injured in an automobile accident – a rarity in his day - and receives immediate medical attention thanks in part to his “intelligent” clothing. With multiple fractures and a hairline crack to his artificial heart, Alain is rushed by air-ambulance to the hospital of the future. ---- This channel offers you full episodes of high quality documentaries.

Wormholes are theoretical structures linking together two points in spacetime. Dr. Dejan Stojkovic and De-Chang Dai paper, Observing a wormhole, theorizes that by observing the motions of stars around a supermassive blackhole it can be determined if a traversable wormhole exists in our universe.

Is it possible to go backwards through time? We travel forwards every day, but traveling back could let us change our past, visit old friends, or manipulate the timeline to our benefit... Although our knowledge of space and time remains incomplete, we can still use what we know to consider possible time machines. But what kind of paradoxes would this entail and how can we resolve them? Join us today on a special journey through time.

Welcome to Jupiter, a world so roomy that it could swallow every planet and moon in the solar system and still have room for more. Yet for all its bulk there is nowhere to land, just an infernal drop into a bottomless sky. Mars is the ruby jewel in our night sky and arguably the hottest travel destination in the Solar System. Here, on the fourth rock from the Sun, is our best chance to step into the rest of the Universe and the most likely place we know to encounter the alien life-forms we might share it with. ---- This channel offers you full episodes of high quality documentaries.

We interview the creators of 3 models of the early universe that imply the big bang came from a black hole in a mother universe. The models are Cosmological Natural Selection (CNS), The Holographic Big Bang and Cosmology with Spin and Torsion. The creators interviewed are Lee Smolin, Nikodem Poplawski and Niayesh Ashfordi. Recently it has also been shown that a theory of quantum gravity called Causal Set Theory may realise CNS. And so we also talk to Stav Zalel who has worked on this idea and cosmologist Aureliein Barau The order of subjects is LS: Lee Smolin NA: Niayesh Ashfordi SZ: Stav Zalel NP: Nikodem Poplowski AB: Aurelien Barau 00:00 Introduction 51:55 LS and SZ on CNS 3:53 the prehistory of CNS 6:08 NA doubt on fine tuning 7:33 NA on The Holographic Big Bang 10:32 NA explains The Holographic Principle 13:41 NP on Cosmology with Spin and Torsion 16:16 NP on anti matter 17:44 SZ on quantum gravity 18:21 LS and NP on the big bounce 20:23 SZ and AB on Causal Set Theory 21:32 SZ on comparison with Loop Quantum Gravity 21:47 AB and SZ on predicting the cosmological constant 23:24 SZ on linking CNS and Causal Set Theory 24:53 NA on string theory connection 25:46 LS on neutron star predictions 30:15 LS on inflation and CNS 31:08 NP on inflation and torsion 33:08 NA on replacing inflation 35:25 LS on CNS versus eternal inflation 36:55 NA on the difference between CNS and The Holographic Big Bang 37:14 LS, NP and NA on entropy 38:40 LS and NA on Roger Penrose’s criticism 40:47 LS, NP, SZ and NA on an eternal past 43:49 LS on answering Leonard Susskind 44:39 LS on scare resources 45:08 NA on CMB predictions 46:06 LS summing up

In 2015, the story of Tabby’s Star, named after discoverer Dr. Tabetha Boyajian, captivated the science news cycle for months with one idea being that the dimming and dipping of the star could be be of an alien civilization building a dyson sphere or constructing a dyson swarm. Up until recently, Tabby's star was so far the only known star to show such unusual slow dimming. Dr. Edward Schmidt is a professor emeritus at the University Nebraska-Lincoln having taught physics and astronomy for over 40 years. His most recent paper looked for analogs of Tabby’s star KIC 8462852 using previously available survey data.

Visit our sponsor, Brilliant: https://brilliant.org/IsaacArthur/ Discussion of advanced extraterrestrial civilizations often hinges on the idea that they may have ascended to a higher state or higher level of reality, and lost interest in us and the rest of the galaxy. While we can't know what technologies or enlightened paths they might have available, we can ask how realistic the portrayals of those aliens might be, and if this notion make sense as a Fermi Paradox solution.

A Paperclip Maximizer is an example of artificial intelligence run amok performing a job, potentially seeking to turn all the Universe into paperclips. But it's also an example of a concept called Instrumental Convergence, where two entities with wildly different ultimate goals might end up acting very much alike. This concept is very important to preparing ourselves for future automation and machine minds, and we'll explore that today.

Planets, like the Earth, could potentially serve as giant telescopes - as explored in our last video (https://youtu.be/jgOTZe07eHA). This happens because the atmosphere refracts light and so bends it into a focus, like a huge spherical lens. Parabolic dishes on Earth can be sued as both telescopes and antennae, and so in the same way - could planets be used as antennae? Today we explore the possibility of using the Jupiter as a giant antennae, perhaps serving as the basis for an interplanetary internet, and how Juno could very well test the idea today.

George Dvorsky says in his article 'Humans Will Never Colonize Mars' on Gizmodo that,“The suggestion that humans will soon set up bustling, long-lasting colonies on Mars is something many of us take for granted. What this lofty vision fails to appreciate, however, are the monumental—if not intractable—challenges awaiting colonists who want to permanently live on Mars. Unless we radically adapt our brains and bodies to the harsh Martian environment, the Red Planet will forever remain off limits to humans.” John Michael Godier and George Dvorsky discuss his article and exactly will humans ever colonize mars? As well as the misconception from people over whether humans will never go to mars or the idea of can we live on mars? They also go over a spacex mars mission update and if there are other planned missions to mars? As well as if virtual space exploration could be feasible. Also. What is the Fermi Paradox? And how does it relate to exploring the solar system in a virtual environment as well as Artificial Intelligence and super intelligence.

Does intelligent alien life exist? Answering the question of are we alone has turned out to be a bit more difficult than was originally envisioned when SETI first began decades ago. At first it was a matter of looking for giant omnidirectional beacons blasting out high energy messages, much like what we saw in the movie contact. But as we’ve gone through the process of searching, it’s becoming evident that such a scenario was in a way wishful thinking. We have seen no such unambiguous beacons, and thinking on just why a civilization would expend massive amounts of energy on a signal has changed. It's very likely to be far more subtle than that, and that any intentional message would be beamed directly at us. But beacons aren’t the only game in town. Since the advent of SETI, other technosignatures beyond radio have been thought of. Now we can look for laser emissions, industrial chemicals in the atmospheres of exoplanets, Dyson swarms, and a host of other signatures that would tell us if there are alien civilizations out there. Where is intelligent life in the universe? John is joined with Isaac Arthur to discuss the Fermi paradox, to try and answer where all of the intelligent life is in the universe, and look at what possible techno signatures are most likely. Dyson spheres and Dyson swarms, von neumann probes, and machine civilizations.

The curiosity rover detects methane on mars. Is methane on mars a sign of life? Mars is giving off a large amount of methane gas. Recently detected by the mars curiosity rover. This news gives new thoughts to old ideas about life on mars. Dr. John McGowan wrote a paper while at NASA ames research center, discussing methane and mars oil. John Michael Godier spoke to Dr. McGowan about that paper and what the implications are for finding life on mars, how having oil on mars could effect spacex mars mission.

28 random dips of light were observed by the Kepler space telescope of the star HD 139139. The random transiting nature of the objects and the light curves were studied by a team that was lead by Dr. Saul Rappaport and Dr. Andrew Vanderburg. This bizarre star so far stands out from the Kepler mission. One explanation includes rapid sunspots. Possible SETI implications include an alien civilization creating an unnatural looking orbits to signal to others that they exist. John Michael Godier spoke to Dr. Andrew Vanderburg about HD 139139.

Could humans ever travel to other galaxies within their lifetime? The immense scale of the Universe seems to prohibit such voyages, after all the nearest galaxy is so far away that it takes light itself - the fastest thing in the Universe - 2.5 million years to complete the trip. Remarkably, there is a trick that might allow humans to accomplish this feat - join us today as we step onboard the constantly accelerating spaceship!
