For the first time ever we have visual confirmation that black holes actually exist and we got it with a telescope the size of our planet.

How can we be so sure of the way celestial bodies behave when they're so far away? With the help of some speakers, garbage cans, and springs of course.

What really happens when you approach the event horizon of a black hole?

Hank explains the science behind recent reports that physics great Stephen Hawking said "there are no black holes." There are. They're just super complicated.

This video is chapter 8 in my series on special relativity, and it presents a hands-on explanation of the resolution to the Twins Paradox using the mechanical minkowski diagram, aka mechanical Lorentz transformation, aka spacetime...

Stephen Hawking recently announced that he'd come up with an answer to one of the biggest questions in physics. But it'll probably be a while before we know exactly what it is.

At the center of a galaxy more than 55 million light-years away, there's a supermassive black hole with the mass of several billion suns. And now, for the first time ever, we can see it. Astrophysicist Sheperd Doeleman, head of the Event...

At the heart of the Milky Way, there's a supermassive black hole that feeds off a spinning disk of hot gas, sucking up anything that ventures too close -- even light. We can't see it, but its event horizon casts a shadow, and an image of...

A naked singularity is something that should be a black hole, but it’s neither black nor a hole. If they exist, they’ll rewrite physics as we know it.

Today, one of the biggest paradoxes in the universe threatens to unravel modern science: the black hole information paradox. Every object in the universe is composed of particles with unique quantum properties and even if an object is...

SciShow Space explores the supermassive black hole spinning at the center of our galaxy, and how we've all learned to live with it in harmony.

From asteroids capable of destroying entire species to supernovae that could exterminate life on Earth, outer space has no shortage of forces that could wreak havoc on our planet. But there's something in space that is even more...

Black Holes are known for consuming everything that falls into them, but is there a point where these galactic devourers can't stomach anymore?

Lots of people believe the Universe is infinite, but there's a good possibility that might not be the case. Which means that there would be an actual edge of the Universe. What happens at that edge? Is there a restaurant?

Explore "How Are Black Holes Formed?" with our catchy video that makes learning about space fascinating and fun! Perfect for kids, this tune will spark your imagination and teach you the science behind the formation of these cosmic wonders.

What is inside a Black Hole? A black hole is really not a celestial body like a planet or a star. There is really no substance there other than a severely curved space-time. It’a a region in space where matter is...

Traveling forward in time is not a problem. You're doing that now. Can we travel backward in time? There is a theoretically possible way to do it using wormholes.



One solution to general relativity...

Time travel is nothing special. You’re time traveling right now into the future. Relativity theory shows higher gravity and higher speed can slow time down enough to allow you to potentially travel far into the...

SUMMARY

The universe is full of opposing forces balanced in a celestial tug-of-war, until they sometimes aren’t. In stars, the two opposing forces are gravity which tries to collapse the star inward, and...

SUMMARY

In 1976, Stephen Hawing proposed that Black Holes, do something impossible according to the laws of quantum mechanics. They destroy information. This is a paradox because information should be conserved in the...

Hawking Radiation DOES'NT Work the Way Hawking Explained it! Here's the Reality...Hawking Radiation: The Oversimplified Picture vs. The Reality...Hawking radiation suggested that black holes are not...

Hawking radiation,Black-Hole Evaporation and black hole explosions! Stephen Hawking theorized that a black hole may not be so black. He showed that when you apply the laws of quantum mechanics to classical physics,...

Holographic Universe? Are we living on a hologram? Or inside a black hole? Our perception is that we live in a three dimensional world. What if our three dimensions, can be equally represented on a two...

Karl Schwarzschild crafted the first exact solution to Einstein's equations of general relativity. He found that as gravity increased around an object, there must be a point where even light could not escape. He theorized black holes.
