How fast are you moving right now?
Even when you’re standing still, you’re moving, because Earth is moving, and so is the solar system, and so is the Milky Way … right?
The real question is compared to what?
Get ready for your introduction to relativity. Galilean relativity, that is. Really makes me wonder what’s absolute.
One thing I don’t agree with in this video is that space is “nothing”. Maybe in an idea sense, and in any useful measurable sense, but even interstellar space has a few atoms per cubic meter. Couldn’t we just measure relative to one of those? Ok, I’ll shut up.
Also, I wish Sulu had said that to Kirk back then. Also also, this narrator sounds a LOT like CGP Grey.
