What Time Is It on the Moon?
If all goes well, we'll be sending astronauts back to the Moon in just a couple of years. And scientists have a lot to figure out before then, including the answer to a seemingly simple question: What time is it up there? Hosted by:...

Complete Solution To The Twins Paradox
This video is about the famous 'Twins paradox' of special relativity, how time can appear to be faster for two different observers at the same time, and which twin really is older (or younger) - the one who stays on earth or the one who...

How Does Gravity Warp the Flow of Time?
There’s a deep connection between gravity and time - gravitational fields seem to slow the pace of time in what we call gravitational time dilation. And today we’ll explore the origin of this effect. And ultimately, we’ll use what we...

Planet X Discovered?? + Challenge Winners!
Some funky orbits near the Kuiper Belt are hinting towards a brand new planet, the elusive ‘Planet X.’ Our friends Mike Brown and Konstantin Batygin of Caltech are working hard to finally spot the potential gas giant through powerful...

When Is Now?
When is now? Seems like a pretty simple question… just look at your watch. But do you and I share the same “now”? Let’s journey from Einstein’s thought experiments about relativity to cutting edge neuroscience research to try and answer...

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...

Do Events Inside Black Holes Happen?
Black holes! From Stephen Hawking to Interstellar, black holes are mammoths in the world of science AND sci-fi. But what exactly IS a black hole? Do events happen inside black holes? Are black holes really a hole? Are black holes really...

Length Contraction and Time Dilation | Special Relativity Ch. 5
This video is chapter 5 in my series on special relativity, and it covers how things that are moving (that is, moving relative to an inertial reference frame) at different speeds appear to be shorter in length... and longer in length....

Why Does Time Slow Down During Car Accidents?
The sensation of time slowing down during intense situations is a commonly reported phenomenon, but what's actually going on?

Impossible Muons
This video is about how terrestrial muons are part of our experimental proof of time dilation, length contraction, and special relativity in general. REFERENCES Cosmic Rays https://en.wikipedia.org/wiki/Cosmic_ray Terrestrial Cosmic Rays...

Spacetime
In this video Paul Andersen explains how the dimensions of space and time are combined in relativistic mechanics. Gravity and velocity can affect both space and time according to Albert Einstein's Special Law of Relativity.

Special Relativity: Crash Course Physics
So we've all heard of relativity, right? But... what is relativity? And how does it relate to light? And motion? In this episode of Crash Course Physics, Shini talks to us about perspective, observation, and how relativity is REALLY weird!

Is Time Travel to the Past Scientifically Possible?
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 predicts an Einstein Rosen bridge,...

What Would Happen If You Traveled At The Speed of Light?
If you travel at the speed of light, your mass will increase exponentially. The speed of light is 300,000 kilometers per second (186,000 miles per second). When you move at this speed, your mass will become infinite. Therefore, infinite...

Does Time Exist, Or Is It A Social Construct?
Research shows that the human brain does not have a single clock dedicated to measuring time that passes. Our experience of time depends on many factors, including memories, emotions, and our level of attention. Time seems to ‘fly’ when...
