No. In about 4 billion years, the sun will expand into a red giant and vaporize earth. Even if humanity will somehow colonize another planet, in about 100 trillion years, the universe will die in coldness and without energy, life is impossible. However, it will certainly become possible to make human lives much longer, yet eternity is a big word so you should be aware of what it actually means.

No To live longer is possible.

Live forever no, to stop aging yes, i do believe we will eventually be able to stop the aging process, but disease and viruses still exist as well as lots of other different ways to die. As a matter of fact i believe alot of people would die at around a 100 or so even if they didnt age, because of thier eating habits.

This is a really cool question. Consider this: Today we can replace parts of brains with machines and function normally. What is to stop us from replacing our whole brain with a computer (it's a long way off but it's possible). Then your consciousness could be preserved on computers. I think that's pretty cool. I doubt anyone alive today will see the day when a computer has the same processing power as our brains though.

No. Unless they can upload our consciousness to a computer or something, and who would really want to be like HAL anyway?

No, we are all meant to die at some point. It's a natural process.

"For God so loved the world that he gave his one and only Son,[a] that whoever believes in him shall not perish but have eternal life. John 3:16

Why? - ;-)

i perceive that very deep in the future we shall take one of two paths,or both,which are,1:become data after having been part machine for so long,or,become a radically different or groups of species through genetic engineering/crossbreeding...thus allowing us to exist for much longer(other than through other advancements/progress)than is currently possible...though im not sure if there is a "Forever",nor how one would cope with living that long...it might be easier for some than others.some individuals might find that eventually taking their own lives would bring them much needed rest...in any case,as capable as mankind is of finding ways to live "forever"(other than through history/the influences it leaves behind),it has shown that it is its greatest enemy,mankind loves to dig its own grave and lie in it...its a possibility,that,at the moment is far out of reach,defeats the purpose of being human(mankind can change,and it must,if it wishes take advantage of such a possibility),and can take away meaning from mankinds existence...

by making our cells regenerate forever every part of our bodies

Yes, but you'll be dead before it happens

Forever is a LONG time. But if we could figure a way outside of this spacetime continuum, it would happen instantly.

Been there did that.

If they do there must be no more children the world could not sustain a population explosion when nobody was dying.

yes, somewhere in the near future, but who wants to live forever? good Q +4

No....and they wouldnt want to anyway

Eventually, I believe we'll be avble to cure most diseases, and halt aging. Unfortunately, it doesn't look like this will happen for anyone alive today :-( But there will always be plane crashes (spaceship crashes) and other accidents.

Pratical immortality is only a decade or so away.

I hear there is, but it takes 100 years to get to the head of the line.

I hope not. That would mean ALL would have the right to live forever, and then harrder and harder choices would have to be made. Prisons would be full of humans that would have to be housed forever, and if we ever did decide to let them out they may be habitual for lesser crimes such as theft, and we would have to decide what to do with such individuals. I believe if we didn't become very harsh on crime, even the petty it would be a crime filled world after a while. Interesting question!

Not under ObamaCare there won't.

Just encode stage 1,2,3, and 4 rhibosome cycles to oscillate the cell betwean stage 2 and stage 3, depending on probability, sell more copies of windows. That could make ya live for twice ever.

I don't believe humans are capable of what it will take to allow people to live forever. It's arrogant to think they are. Now, God, on the other hand IS capable and has promised to do so. And he hasn't broke a promise yet.

i hope not, we would be overcrowded and starve from lack of enough food to feed everyone and can you imagine all the garbage and human waste ?

This concept is synonamous with mutually assured destruction. Well, I suppose if you stearalized all but a handful of people, than perhaps not. But still, our universe itself does not have an infinite lifespan. All things are ephermeral, deal with it.

try reading this if you're interested. Some cool stuff in the "See also" links too. http://en.wikipedia.org/wiki/Biological_immortality

Living forever just turns life into conscious death. What gives life value is the fact that it is finite. You live a certain amount of time, and then you die. With that said, it doesn't really matter. The Earth is going to become increasingly less habitable as the sun heats up over the next billion years, it will eventually make it too hot for liquid water on the surface of the Earth. Another 4 billion years and the Earth most likely get's annihilated by the sun as it expands out in it's red giant phase. But let's say we developed interstellar space travel before that(like we should be working harder on now if we really want to ensure our continued survival). Even if we did manage to evade or manipulate our way out of stellar and galactic catastrophes by taking to the stars, we still have one more problem with living eternally. There are two ends to our universe, one that could happen, and one that looks like it will probably happen. Our universe is expanding, the very spacetime that makes it up is expanding and accelerating even. Estimates put the upper limit of that spacetime expansion at a maximum around 10^(10x100) years from now. That's a really, really long time, but you said forever so I'm going with that. At 10 to the googl power years, space will be so expanded, subatomic nuclei will rip apart. Everything ending in a giant rip and then just a cold black void. Nothing you can do to stop it either. The other option is the universe slows, and reverses it's movement, crunching back in on itself. Much more happy because hey everyone probably starts over now instead of going dark, but you're still all dead. So no. You can extend their effective lifetime for a longass time by maybe figuring out how to move consciousness onto virtual platforms and creating infomorphs and whatnot (trying to make better body parts just wouldn't work in the long-run, infomorphs are much more durable). But it comes to an end one way or the other.

I'm immortal. Every day I say, "I'm immortal." So far I have been right - every day. One day I may be prove wrong - but only once. That means I will be well over 99.99% correct - and that's about as close to 100% as anything in this world can get. :-) +5

Believe in the Flying Spaghetti Monster and you shall have eternal life.

The only way would be to transfer our minds into a new body. That way we could choose what body we wanted until it wore out. Then we would move into another body, just like when you buy a house. That would be totally cool.

With stem cells you could live to 300

no.

There is an aging gene that once they turn it off dying of old age won't be a problem. Negating accidents is another issue. I think that yes eventually there will be a way to live forever. It would have to be something like "Ghost in the SHell" where your mind is transfered into an electronic brain, but then that brings up the issue of is that really you, and is it really "living"? But at least back-ups of you could be made but even that doesn't guarantee living forever. What if it crashes or a weapon or virus erases the data? But really it would become horrible living after enough time had past, it would be torture more than a blessing
