Time travel theory avoids grandfather paradox

[KIAman]

Then that would mean there's a universe for every universe...which means there would be an infinite # of universes

Yup http://en.wikipedia.org/wiki/Multiverse


Personally, I don't believe in multiverse, just defining the theory.

time is an illusion the past present and future are all happening at the same time. now. prove me wrong.

I basically agree, but this is funny:

If someone uses a term like "at the same time"...it already implies something like the oldfashioned idea of time..otherwise using "at the same time" wouldnt make any sense 🙂

a) in hundred years all our cars fly
b) in hundred years cars wont fly

Both possibilities are there and could be equally likely. Causalities and whatever decides whether a) becomes true or b)

If you say multiverse doesnt exist...wouldnt you need to prove that one of them (a or b) is false since only one of them can be true?

Would you say its already pre-determined which one will occur?

iirc time travel into the past is an implication of general relativity.

I think relativity only allows for time travel into the future.

Why isn't it called Infiniverse?

I don't understand why physicists waste their time trying to prove time travel into the past is possible. It's not, and attempting to prove that it is is a colossal waste of effort. It's a sci fi device used for entertainment. I don't see biologists trying to prove how it could be possible for a human to fly like superman.

All you need is two more dimensions to make this happen, 4th and 5th. Technically only the 4th is needed (time), but you'd need the 5th in order to see all points along the 4th. I suppose in order to make this particular theory relevant you'd need the 6th dimension as well, which would all you to see all possibilities (5th) along all points in time (4th). But simply being able to manipulate the 5th dimension will suffice. You'd just be doing it blindly (you need to be 1 dimension above the dimension you exist in in order to "see" the full extent of that dimension).

what if you went back in time, took your grandfather forward in time to impregnate your gam gams, took him back to his time and then killed him, and just to be safe you impregnate your great aunt?
