Are wormholes real or are they just magic disguised as physics and maths? And if they are real how do they work and where can we find them?

What's the hottest it could possibly get in our solar system? Maybe we'll look deeper into the universe next.

The Death Star could destroy a planet, but what are some realistic ways it could happen.

The hottest and coldest temperatures in our universe are rarely witnessed, but in these rare spots, our understanding of physics is challenged. Weird things happen at extreme hot and absolute cold.

If you fell from space, what would happen to your body?

Why is Earth is a blue planet? Because it's covered in water! Where did Earth's water come from?

What is a Black Hole Civilization?

We live in a beautiful world, and these amazing facts will blow your mind.

This video is about the line between Brown dwarfs and gas giant planets (aka super Jupiter's): does it exist?

Scientists have JUST published this new observation.

Finding alien life on a distant planet would be amazing news - or would it? If we are not the only intelligent life in the universe, this probably means our days are numbered and doom is certain.

What will happen to the planet Earth?

Vsauce host Michael Stevens digs deep into the ever-changing concept of the direction "down," what causes things to fall, and digs into how masses really, really want to pull towards each other in our universe, thanks to gravitational forces.

The U.S. and Russia have announced plans to put a new structure in the orbit of the moon. What will it look like?

Over the course of history, we've discovered hundreds of thousands of asteroids. But how do astronomers discover these bits of rock and metal? How many have they found? And how do they tell asteroids apart? Carrie Nugent shares the story of the very first asteroid ever discovered and explains how asteroid hunters search for these celestial bodies.

Why is the universe organized the way it is? And why is it so empty? From planets and stars to superclusters and galactic filaments, the universe's largest structures formed because of its smallest. In this special collaboration with PHD Comics, we'll learn how the earliest, quantumest blips seeded the structure of everything everywhere.

What happens if we bring the sun to earth? No, seriously.

The light from KIC 8462852 faded again, and scientists have some new theories about what's behind astronomy's most mysterious star.

This video is about why it's harder to successfully land spacecraft and landers and rovers on Mars than on Earth, or Venus, or the Moon, or Titan, or asteroids. It all comes down to atmospheric density! When there's no atmosphere, you can do a powered descent in a flimsy tinfoil spacecraft like the Lunar Module, and when there's plenty of atmosphere you can do an unpowered descent via heat shield and parachutes like the space shuttle, Apollo command module, Soyuz, Huygens, etc. But on Mars with its thin air, you have to do both powered & unpowered descent, getting the worst of both worlds.
