also something interesting i learned from Vsauce yesterday --- Quote from: Khaz on October 14, 2017, 05:46:42 PM ---did you know 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 --- End quote --- heres the video. we're lonelier than we think |

I would think that it just means you individually are moving faster than things around you rather than everything else --- End quote --- https://en.wikipedia.org/wiki/Time_dilation this gif p much sums it up 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. |

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. |
