At a rough 10 trillion kms = 1 light year,
Sombrero galaxy is 31.1 million light years away,
1 quadrillion kms = 100 light years,
1 quintillion kms = 100,000 light years,
100 quintillion km = 10 million light years,
so basically we are looking at an object 300 quintillion kms away
At this fraction of light speed 0.99999999999999999999 to the person inside the spaceship only 1.6 days will pass. But to a person on earth, it would be 31.1 million light years. Crazy eh?
- ben_w 2y agoNot hugely crazy, it's a function that asymptotically approaches infinity. If you want crazy effects, IIRC the relativistic time dilation factor is also the temperature dilation factor, which means at that speed the cosmic microwave background radiation will cause positron-electron pair production in the hull of the spaceship, to a depth that is dependent on how effectively it blocks extremely hard gamna rays — like, if you're in a space suit, it will be throughout your entire body because neither the suit nor your bones are particularly opaque at that energy level.
