...and that we know exist suddenly cease to exist? What would become of our memories of them, the knowledge of them, would that abruptly be wiped out? For example, if we are someday able to travel back in time and stop Hitler from exterminating thousands of people. If suddenly he did not have a hand in killing them and they lived, how would that change the time we are living in now? If we travelled back in time today and changed history, would my knowledge change? What about the history written in books? Would it be instantaneous? Would it leave a memory residue? For instance, if before we changed history, I travelled to a certain place, say Paris, regularly would I have that familiar deja vu feeling if I travelled there after we changed history, yet had never been there before within my new life? Could the human mind withstand a significant change in history? Will time travel ever be possible? And if it does, who will decide what we can and can not do with this ability?

I think it would be hard for any past era to accept a future that they could not understand as it is putting the cart in front of the horse. You would be labeled a heretic.

If you go back 2000 years and change one sex act that produces a child (either cause a child or prevent one from existing), then the resulting change will expand exponentially; e.g., a woman who would have married that child marries someone else, and then that someone else's spouse marries someone else, and so forth. By the time this reaches our present time, everyone would be different! Everyone that we know would cease to exist, including the person who messed with the couple having sex. So all this would NOT have happened, and everyone is like we see it now, so that the sex changer would do his deed anyway, and so everyone would be completely different - this roundabout thing is a blatant contradiction. So not only would a lot of people be different, but it also could not occur in the first place. I think time travel is impossible.

The human mind would be able to withstand history because it wouldn't be history if we could change certain events.
Because we are a progression of past events and historical moments, we would simply be at another stage in human conduct.
Imagine if all of the money that was spent on World War I and II, Korea, Viet Nam, etc was given to Jerry Lewis, instead of spending money on armaments of war and conflict.
Who knows what was lost in fighting wars and spent resources of people killing people...
Who knows !

Time travel is impossible .... and won't be possible ...
If time travel will be possible in the future , then some people from the future must be living with us today ....
The Past cannot be Changed ...
To understand more why the past cannot be changed , watch the movie "Time machine" ....

You have been reading **far** too much Science Fiction.
And anyway, all of those things *did* happen in the infinite 'parallel universes' that are created every time a wave function collapses (to use the old Copenhagen interpretation language of quantum mechanics)

i think time travel will be possible one day NO QUESTION and who knows, maybe some of those UFO sightings are future time travelers, I dunno, but I think it's pretty cool to think about though.
