Is The Universe Finite?
Every time you walk out the door, light from the Big Bang strikes your face, enters your eyes. This is the cosmic microwave background radiation - the left-over heat-glow from the very early universe. We can’t see this microwave light...

The Strange Universe of Gravitational Lensing
Niels Bohr, a Danish Physicist said “Everything we call real is made of things that cannot be regarded .” Is what we see perceived to be real or is it an illusion? In the world of our mind’s eye, light travels in a straight line. In...

General Relativity Explained in 7 Levels of Difficulty
This video covers the General theory of Relativity, developed by Albert Einstein, from basic simple levels (it's gravity, curved space) through to the concepts of how curved spacetime is represented by psuedo-Riemannian manifolds with...

Einstein's Biggest Blunder, Explained
This video is about how Albert Einstein made a mistake when applying the Field Equations of General Relativity to cosmology (in particular, to a static, constant density universe), and solved the problem by introducing the cosmological...

Can a Circle Be a Straight Line?
On this week's episode of Spacetime, Gabe talks about what it actually means for a line to be straight so we can better understand what we mean by the idea of "curved Spacetime". This is Part One of our series on General relativity, so...

TED-ED: The fundamentals of space-time: Part 3 - Andrew Pontzen and Tom Whyntie
In the first two lessons of this series on space-time, we've dealt with objects moving at constant speeds, with straight world lines, in space-time. But what happens when you throw gravity into the mix? In this third and final lesson,...

How Cosmic Inflation Flattened the Universe
Although much of the Big Bang Theory is widely accepted to be true, it only gets us part of the way there. Observable truths such as the CMB and the flatness of our universe reveal that there is no way the universe has been expanding at...

How Can the Universe Be Flat?
Can geometry predict the future? Cosmologists think the overall curvature of universe can tell us secrets about how it will eventually end.

What Happens At The Edge Of The Universe?
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?

Why Do Our Fingers Curl While We Sleep?
Your fingers curl inwards when you sleep because of the way the muscles in your arms relax and due to the length of the tendons that connect the bones in the finger to the muscles in the arm. The movement of fingers, like any other body...
