[QUOTE="tocool340"]Well, firstly they need to figure out how to regenerate brain cells because once death occurs, your body, including your brain, will begin decaying. If they brought someone back once they died, they will most likely return mildly "retarded" (Or handicap. Or vegetable. Whatever you'd like to call it...), have lapse of memory depending on the spot the brain first begin decaying, and other complications that happens when the brain gets damaged. They could be considered alive, but I doubt those who come back, even if they found a way to regenerate brain cells will be the same. Doesn't really matter what they say they seen during their death experience since it could be their last thoughts/dreams prior to them dying. Sort of like putting a computer in hibernation where it turns off but comes back to resume the state it was in prior to it hibernation.... Hmmmm....they had to reconstruct him from nearly scratch, which I doubt we'll ever require such technology before our sun burns out because if we did, I definitely believe we'd have a problem with people not being able to stay dead. All it takes is someone to reconstruct a Hitler Stalin, or any past lunatic for there to be a major problem....chrisrooR
Our sun's schedueled to burn out in like a couple of billion years. If humanity's still alive at that time I think we'd have the technology by then to be living in other solar systems entirely.
We're probably going to be living in other solar systems in less than a couple of thousand years at this rate.No we won't. That would require us to manufacture a spaceship large enough to carry any sort of sustainable human population, and fast enough to get there while the humans are still alive. Just getting to the nearest star is 3.4 million light years away, and travelling at the speed of the fastest object humans have ever manufactured is the Voyage 1 spacecraft, travelling at 17 kilometres per second. It would take that 70,000 years to reach Alpha Centari. totally doable
