That is why one must also consider the relative dimensions in space when constructing a time machine...
Spacetime machine just doesn't have the same ring to it
This implies a privileged reference frame
One of my high thoughts was thinking about time travel and wondering if the present is the only time when time as motion exists.
If so, and we were able to time travel into the past, we would arrive in an unmoving universe, unable to escape and trapped for all of eternity.
It kind of made me not want to be able to time travel.
In my head it made me think of time as a wave and the present as being like a surfboarder on the wave.
If you were to jump off of the surfboard, you would arrive at a point where there was no "wave" and therefore be unable to surf.
I love how this comment sounds like an even more stoned translation of the first one.
Sirens of Titan by Kurt Vonnegut touches on this subject. It’s a fun read.
There is a short movie about time travel where they go a few hours or so into the past and end up somewhere else in the neighborhood
