Multiple Timelines

Can Some one answer this question please. If someone was to go back in time, wouldn't that mean theres a seperate timeline; for it to be registred as an actual event. Because if the future changed from what it was before doesn't mean it still didn't happen.

Because if someone was to go back in time wouldn't they disapear because the wouldn't have exsisted past their own birth.

One more question, just because light is the fastest measurable constant in the universe, why does that set it as the barrier between time.
Sorry If i didn't explain it that well but doesn't anyone know what I mean?

Go back through the different threads here. Your questions are answered fairly thoroughly in a few threads in Science and Tech AND in Paranormal Studies. See the thread "The Philosophy of Time Travel", right here in the Science and Tech forum. A few members have posted their theories as to how time travel is or isn't possible

Hi, thanks for you comment, sorry its taken me so wrong to reply, I'm not a regular log on person.

I have some really strong views on alot of diffrent things and now alot of stuff alot of people dont. Urm but I've never really managed to grasp the whole ATS things.

Can you literally spend lots of time on here conversing about stuff?
