On this StarTalk explainer, Neil deGrasse Tyson and comic co-host Chuck Nice investigate the science of wormholes and how they work. You’ll learn how gravity is the curvature of spacetime. We talk about the “speed limit” of the universe and how to break it using a wormhole. But, how do you keep a wormhole open? Is it prone to collapse? All that, plus, Neil and Chuck explore classic time travel movies like Bill & Ted’s Excellent Adventure, Back to the Future, Time Bandits, Contact, and more!

The Way of the Wormhole | Juan Maldacena
Einstein's theory of general relativity predicted the warping of spacetime due to gravitational forces. When this bending becomes so strong that a region of space folds like a piece of paper, the hypothetical tunnels known as wormholes can be formed. The extreme gravitational conditions necessary for this to happen may occur around supermassive black holes. But do wormholes really exist? And if so, how can we find them? When taken to the extreme, gravity can create some intriguing visual effects known as gravitational lensing, that can be observed through telescopes. From the outside, wormholes can appear similar to black holes, but while moving in front of a distant star, a wormhole big enough to fit a spaceship would create a very specific type of this weird laughing mirror effect. Therefore, when it comes to hunting wormholes, looking for the distant signatures of smaller gravity lenses known as micro lenses could be the way to go. Just as optical telescopes collect visible light, so do radio telescopes collect the radio waves emitted by stars, galaxies, black holes and perhaps wormholes. Investigating ways to distinguish a wormhole from a black hole, researchers have focused on supermassive black holes with masses millions to billions of times that of the sun, which are thought to dwell at the hearts of most, if not all, galaxies. For example, at the center of our Milky Way galaxy lies Sagittarius A, a monster black hole that is about 4.5 million solar masses in size. What if such an “active galactic nucleus” (AGN) were a wormhole mouth rather than a supermassive black hole? Any matter falling into the mouth of a supermassive wormhole would likely travel at extraordinarily high speeds due to its powerful gravitational fields. The collision in the wormhole's throat of matter flowing through both mouths would result in spheres of plasma expanding from the wormhole at nearly the speed of light. Those spheres can reach temperatures of about 10 trillion degrees Celsius and would produce gamma rays with extremely high energies. In contrast, accretion disks of AGNs are too cold to emit gamma radiation. Moreover, although jets from AGNs can emit gamma rays, they would mostly travel in the same direction as the jets — any traveling out in a sphere might suggest they came from a wormhole. All in all, there are several ways in which the gamma radiation emitted by wormholes has a distinctive spectrum much different from those of supermassive black holes. An observation of such radiation would serve as convincing evidence of their existence. Researchers have also considered the possibility that wormholes can act as natural particle accelerators. The high-energy cosmic rays produced by such a scheme could be detected by sensitive radio telescopes as well. It is thought that this phenomenon may occur when a wormhole generates and maintains a magnetic field, which might also explain the observation of such fields in cosmic voids. In addition to telescopes, gravitational wave detectors could be used to detect wormholes in deep space. The United States–based Advanced LIGO, or Laser Interferometer Gravitational-Wave Observatory, as well as the Advanced Virgo detector near Pisa, Italy, have already detected ripples in spacetime caused by the merging of two black holes or dense stellar corpses called neutron stars. But scientists have also considered a black hole with a mass five times the sun’s, orbiting a wormhole billions of light years from Earth. As the black hole swings around the wormhole, the researchers calculated, it would begin to spiral inward as if it were orbiting another black hole. Initially, the resulting gravitational waves would look like a standard signature for two black holes, a pattern of waves that increase in frequency over time called a chirp.

What Wormholes Would Actually Look Like According To Physics (VR/360)
Using relativistic raytracing I created 360 videos of what it looks like to travel through wormholes. We've seen wormholes in TV Shows, Movies and Video games but very few get this right. There are many formulations for wormhole geometry, and I use two, the Ellis wormhole (also known as Morris-Thorne) and the DNEG wormhole used for the movie 'Interstellar' The starting point for this was the paper which describes the geometry of the wormhole used in Interstellar which describes the geometry they used and an algorithm
Unfortunately this algorithm uses a coordinate system which causes singularities that generate errors in some parts of the view which made it bad for 360 cameras, so I improved the system to make it safe and also thousands of times faster. (
The basis for the code is David Madore's black hole rendering code (black holes are coming soon) but everything has been changed at this point and I've added a ton of new features.
http://www.madore.org/~david/math/kerr.html Many of the skymaps were taken from Eve Online, which introduced wormholes to its game universe 10 years ago in the Apocrypha expansion. I'd originally intended for this to be part of my fanfest presentation before fanfest was cancelled. There will be a follow up non-360 video showing some other renders and explanations, like what it looks like when we observe someone else falling through a wormhole. Then I'll make the code available on my patreon page.
Neil deGrasse Tyson and Brian Cox Explore Wormholes and Causality

Are Wormholes Real? With Dr. Dejan Stojkovic
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.

“What would happen if you fell into a black hole? For a long time, the only acceptable answer was that you would die. That is, unless a theoretical wormhole—a portal in spacetime between two black holes—were to save you.” Wormholes Might Burrow Through Black Hole Cores
“The weird physics of a black hole's singularity could turn our "classical" idea about black holes on its head. What if general relativity breaks down and the singularity isn't a singularity at all? What if we replace the singularity with a wormhole? Suddenly, instead of being the ultimate trash compactors of the universe, black holes become the ultimate sci-fi dream: they could be space-time transportation hubs.” The Oldest Black Hole Ever Found Is Almost as Old as the Universe Itself
“A huge black hole has just been discovered that is about 13 billion light-years old – almost as old as the universe itself. The find of this supermassive black hole is puzzling astronomers because they can't figure out how this black hole was formed so early in the universe's history.” ____________________ Seeker inspires us to see the world through the lens of science and evokes a sense of curiosity, optimism and adventure.

https://www.youtube.com/watch?v=4tcoZNrSveE&feature=youtu.be With all my enthusiasm for humanity’s future in space, there’s one glaring problem. We’re soft meat bags of mostly water, and those other stars are really really far away. Even with the most optimistic spaceflight technologies we can imagine, we’re never going to reach another star in a human lifetime. Reality tells us that even the most nearby stars are incomprehensibly far away, and would require vast amounts of energy or time to make the journey. Reality says that we’d need a ship that can somehow last for hundreds or thousands of years, while generation after generation of astronauts are born, live their lives and die in transit to another star. Science fiction, on the other hand, woos us with its beguiling methods of advanced propulsion. Crank up the warp drive and watch the stars streak past us, making a journey to Alpha Centauri as quick as a pleasure cruise. You know what’s even easier? A wormhole; a magical gateway that connects two points in space and time with one another. Just align the chevrons to dial in your destination, wait for the stargate to stabilize and then just walk… walk! to your destination half a galaxy away. Yeah, that would be really nice. Someone should really get around to inventing these wormholes, ushering in a bold new future of intergalactic speedwalking. What are wormholes, exactly, and how soon until I get to use one?. A wormhole, also known as an Einstein-Rosen bridge is a theoretical method of folding space and time so that you could connect two places in space together. You could then travel instantaneously from one place to another. We’ll use that classic demonstration from the movie Interstellar, where you draw a line from two points, on a piece of paper and then fold the paper over and jab your pencil through to shorten the journey. That works great on paper, but is this actual physics? As Einstein taught us, gravity isn’t a force that pulls matter like magnetism, it’s actually a warping of spacetime. The Moon thinks it’s just following a straight line through space, but it’s actually following the warped path created by the Earth’s gravity. And so, according to Einstein and physicist Nathan Rosen, you could tangle up spacetime so tightly that two points share the same physical location. If you could then keep the whole thing stable, you could carefully separate the two regions of spacetime so they’re still the same location, but separated by whatever distance you like. Climb down the gravitational well of one side of the wormhole, and then instantaneously appear at the other location. Millions or billions of light-years away. While wormholes are theoretically possible to create, they’re practically impossible from what we currently understand. -------
