| highwaystar101 said: Also, if you could travel to another star at near the speed of light, you could travel to another star within a life time as time is relative (the faster you travel towards the speed of light, the slower your time ticks). It would be feasible for some hyper advanced alien race capable of travelling close to the speed of light (I would love to know where they got the energy from to do that lol) they could travel to many stars within a single life time. But because there are hundreds of billions of stars in the milky way I find it unlikely that they come across other intelligent life very often (if at all). The milky way would require a lot of exploration. |
How much time of Sun's irradiated energy would we need to get a few ships to, say, 0,9999c if we could keep it all?
