at 1/1000th of a light-year away our sun would look like a regular star in the sky
at 90 light-years away our sun would disappear because our sun is pretty small compared to most stars.
BUT, almost all of the stars we see in our night sky are 90+ light-years away. meaning all of those stars that we see and marvel at at night.... if there were to be life in any of those systems... they cant see us back

from the blue clock's perspective the red clock is moving slower, but from the red clock's perspective the blue clock is moving faster.

thats pretty weird how that works
also those equations are gnarly
IkeTheGeneric:
FTL travel would be interesting, because everyone planet or station bound will experience time differently from you, it would make any meaningful interaction between ship and colony difficult.

ive always questioned FTL travel
the way it works in cinema/games is pretty straightforward and simple but im afraid it isnt as simple as that
also what do you guys think dark matter is? we know it exists but we just dont know what it is or what its made of.
