Physicists and philosophers have long struggled with the grandparent paradox.

Have they? Has anyone even proven paradoxes CAN exist?

The objections to time travel have always struck me as so much useless mental masturbation when the mere act of pondering such things as paradox REQUIRES one to actually travel in time to complete the thought. Obviously time travel is possible as everything is doing it constantly and at different rates. All we have to do is figure out how to change direction.

If you go back in time and prevent your grandparents from meeting, you don't wipe out the "future" you came from.  You just put yourself on a different branch.  The past where they met still occurs.  The resulting future still occurs.  But your subjective self creates a new branch and then you exist and move forward on that new branch, based on your interference with the original past event of their meeting.

Yeah, that's a hopeful theory. The path where your grandparents travel forward in time and kill your ass is also a possibility - but of course, only backward time travel is possible, right?

Time travel as in time reversal? I think the most they'll ever achieve is going back in time 40 minutes.

You just change the path of time you were on to one where Hitler was killed by your own hand.

With infinite universes all possible outcomes can be true.  You don't change any of them.  You just move to different ones.

I'm just playing a little mental game in which the "paradox" is obviated.

"Time travel may now be possible"

...whatever THAT means.

Also:

Thou shalt not violate causality within my historic light cone. Or else.

Also:

If the universe of discourse permits the possibility of time travel and of changing the past, then no time machine will be invented in that universe.

That is presupposing a multiverse reality and not a closed time system with a a static deterministic equilibrium where it would be actually impossible for you to create a paradox. Every attempt to alter the past would be blocked so you can not kill your grandparents or stop Gore from winning in 2000 or keep Hans  Schicklgruber from rising to power in Germany during the 30's. These things happened and no time traveler can change them.

Argh, no. This is a common misconception, but this is not how infinities work.

You can have a set of infinities that are still bounded.

For instance: Let me define n. n is any number such that n-1>0, and n+1<3.

Basically, any number between 1 and 2. There are clearly an infinite number of n's.

*NONE* of those n's are 3.

Thus, one could in theory have an infinite number of universes exist *BUT NOT* have "every concievable universe" exist. You could have an infinite number of universes, but not one universe who's existence wipes out all other universes, etc etc.

The acceptance of time travel has always struck me as useless mental masturbation when the mere fact that physics don't give a sh*t that you want to go back in time and kill your grandparents. Obviously time travel isn't possible because the past only exists in our human minds. 1943 doesn't exist anywhere. It is like walking down a sidewalk that is disintegrating once you get past that point. All we have to do is figure out to be happy in this time. You only get one shot. Don't f*ck it up.

Now of course achieving time travel means jack shiat if we also don't have a means of moving about in space as well, otherwise you'll go back in time to your grandfather era to find yourself in relatively empty space no where near a planet, or worse much closer to a planets surface then you intended to.

You could "time-travel" in a song through several generations, and become your own Grandpa.

http://en.wikipedia.org/wiki/I'm_My_Own_Grandpa

Many, many years ago when I was twenty-three
I was married to a widow who was pretty as could be
This widow had a grown-up daughter who had hair of red
My father fell in love with her and soon they too were wed

This made my dad my son-in-law and really changed my life
For now my daughter was my mother, 'cause she was my father's wife
And to complicate the matter, even though it brought me joy
I soon became the father of a bouncing baby boy

My little baby then became a brother-in-law to dad
And so became my uncle, though it made me very sad
For if he were my uncle, then that also made him brother
Of the widow's grownup daughter, who was of course my step-mother

Father's wife then had a son who kept them on the run
And he became my grandchild, for he was my daughter's son
My wife is now my mother's mother and it makes me blue
Because although she is my wife, she's my grandmother too

Now if my wife is my grandmother, then I'm her grandchild
And every time I think of it, it nearly drives me wild
'Cause now I have become the strangest 'case you ever saw
As husband of my grandmother, I am my own grandpa

I'm my own grandpa, I'm my own grandpa
It sounds funny, I know but it really is so
I'm my own grandpa

The closest thing to time travel that we'll ever do would be FTL travel where you leave the earth and when you get back 100yrs have past. In this instance, you had better be good friends with whoever you travel with since everyone else you know will be dead by the time you get back home.

What if the reason they didn't invent time travel is because they got disapointed because their future selves didn't show up, so they never bothered to try, and thats why they didn't show up to the meeting to show that it worked.

*mind blown*

No matter what can be done in a lab with photons or sub-atomic particles, we will never be able to go back in time. The past is no more. The future doesn't exist yet. The present is all there is.

It means even if the number of possible universes is infinite, it doesn't necessarily follow that every conceivable universe exists.
