the present moving in a different direction is called a parallel universe. A parallel universe would mean the data would have never been sent. Paradox.

I think it might be possible. My friends are always saying stuff like "Well if it is possible why aren't we seeing people from the future yet?" It's because if they came out and said they were from the future , our government would harass them and interrogate them for answers, which could mess up the fabric of reality!

Well if you do it in the way they said at the end, they might start showing up once they figure out how to make one.

It isn't a paradox.

Universe A ----> option 1: normal way ----> future X: People send information to Universe A
Universe A ----> option 2: altered by information from X ----> Future Y

Once the information from future X reaches universe A, Universe A immediately turns into something else.

It is because all possible universes in all possible times exist(, outside of time).

I see no paradox.

Also, the 'oh my god what if you killed your grandfather' is a lame paradox I personally think. It would actually change the future somewhat (and thus create some sort of paradox) if you would kick over a single garbage can. Like that poem/story about how the clap of a butterflies wings can cause a hurricane, you know?

It just always appears the ONLY way to have a paradox with time travel is if you kill your old man's old man.
