According to the Internet, Gravitational waves 'are distortions in the fabric of space and time'. So does that mean there really could be parallel universes? And wouldn't that also mean that you could, in theory...
... travel back in time? Or forward in time? It kind of blows my mind to think of time having a ripple effect, but that's what these waves are - space ripples. How is space time different from regular time? What does this mean for us on Earth? I could spend hours reading about this stuff, but I'd love some suggestions about a book on this topic.
