Alright this is just something i've been thinking about recently...now bare with me because its a little sketchy.

Lets say...in 300 years...we develop the ability to live forever...but what about those who are dead?

Well lets say in 2000 years we develop time travel abilities and safety techniques to protect time. We could then therefore remove people from time the instant they died and replace them with a replica that had everything that they had...except it was never alive to begin with, it was already dead when compiled, therefore we are not depriving it of life.

But wait! Where do we put all these people you say? Well lets say that sometime between now and 2000 years from now (or however long these abilities may take) we develop instantaneous space travel...We could change the planets we live on to suite our needs...

Well thats all great and everything but what about when we fill every planet in the universe up? Well I haven't thought that far...maybe there is something to (help me out with the name here) Sloan's multi verse theory in which there are numerous universe...if we developed dimension travel we could host people for eternity, since in this particular theory, universe are continuously created.

Of course by then medical techniques will be so advanced that we can heal every person of every disease or deformity they may have had...and hopefully we can heal the mentally handicapped as well.

I wasn't really sure where this should be put...butI figured that this is a tech thing...so maybe techy people can think about this and reply.
