The Impossible Physics of Faster-Than-Light Travel
Here in the real world, we have to obey the laws of physics. And physics is very strict about nothing moving faster than the speed of light. Or is it? While the laws of relativity forbid you and I from moving faster than light, the mathematics of relativity still work even at faster-than-light speeds. This means we can find out what it would look like if we could break the universe’s speed limit.
