The Geometry of Causality | Space Time

This episode is sponsored by Audible. The special theory of relativity tells us that one person’s past may be another’s future. When time is relative, paradoxes threaten. Today, we peer deeper into Einstein’s theory to find that the immutable ordering of cause and effect emerges when we discover the causal geography of spacetime. Recently, we’ve

Speed of Light Thank You!

Dear citizens of the universe, You probably know that light can reach two hundred ninety nine thousand, seven hundred ninety two measly kilometers in a second, but did you also know that physics can now reach over two hundred ninety nine thousand, seven hundred ninety two amazing people in a minute? We’ve broken the speed

Misconceptions About the Universe

It has been a time of time in which the universe was expanding so rapidly that its parts were far apart For some of them larger than the speed of light itself this time we live now many people are fascinated From the fact that during the expansion of the universe immediately after Anbthaqh into

Will This Go Faster Than Light?

The speed of light is meant to be the ultimate speed limit in the universe. According to Einstein’s special theory of relativity, nothing should move through space faster than light. But that doesn’t stop people from trying. Every day I get a lot of messages proposing ways to go faster than the speed of light.

Which Way Is Down?

Hey Vsauce! Michael here. Down here. But which way is down? And how much does down weigh? Well, down weighs about a hundredth of a gram per cubic centimeter. It is light and airy which makes it a great source of insulation and buoyancy for water birds but if you let go of down… It

All through elementary school and high school you grow up hearing about the flat earth we live on and doing boring flat-earth physics homework and then (if you’re lucky enough) you

Why can’t you go faster than light?

Over the last hundred years or so, scientists have pushed our understanding of the universe into some extreme conditions, for example the world of the very small, the realm of very high speeds and the under the frigid conditions of near absolute zero. While each of us have developed an intuition about how the world
