Why Gravity Is A Lie, explained in Zero G

Gravity is a lie. I went into zero gravity to explain why…

But it won't be easy because gravity is actually one of the most controversial subjects in all of physics.

This is not some philosophical debate. A huge amount of the tech you use every day depends on our current (limited) understanding of gravity.

If we can understand gravity a little bit better, we can build more things that are huge if true!

So in this video, I joined the European Space Agency on a real zero gravity flight and interviewed theoretical physicists to understand: What really IS gravity? And what are the real life sci-fi ways we might use it in the future?
