You know ... they have teleported a single atom and that's startrek shit ... so who's to say we wont be able to find a way within 100 + years of travelling at the speed of light?
Plus ... who'd wanna go to the next galaxy? You might just be late for a lunch date  |
Satellites in space all move at speeds fast enough that time diliation has to be factored in. Without it being factored in things like GPS wouldn't work. With it factored in, they work!
And they move particles at near speeds of light in particle accelerators all the time, but that's single atoms moving close to the speed of light, but never at the speed of light. Traveling at the speed of light is impossible as long as you have any mass at all, it just can't be done.
Even gravity goes at the speed of light, so if the sun exploded now, the Earth would keep orbiting around it for another 8 minutes before flinging off on a tangent. We'd see it burning in the sky for 8 minutes after it actually exploded.
