I’m wondering if interstellar travel is possible. So I guess the starting point is figuring out FTL travel.
In: 1302
FTL travel is going back in time. This can create causality paradoxes. Which the universe seems to rly hate.
The speed of light is the limit because its the speed of causality.
For anything with mass to go just as fast as light they need infinity energy… there is just no such thing.
