A couple of days ago I came across the PBS Spacetime youtube channel, and I’ve been watching it’s videos ever since. Fascinating stuff, although I can’t pretend to understand all the science and maths he comes out with. Today I would like to flag this video up, discussing whether a warp drive is possible. It turns out it is, theoretically at least. There are a lot of hurdles to get over, but in theory mankind could one day fold spacetime to travel faster than light. I think that is awesome. If, like me, you’re fascinated by this sort of stuff but don’t have the background to understand all the complicated maths, these videos are well worth a look.
