Is time travel possible ? i think yes somehow we can travel through time just like these movies we've watched well not exactly like movies :D
so what do you think ?
Absolutely not!!!
If you spin very fast, you can meet yourself :)
Can chatting with people in different time zones be considered as a kind of time travelling?
In physics class, we studied Feynman diagrams in which positrons appeared to be electrons that just happened to be traveling backwards in time. We were told that this was purely a matter of mathematical equivalence and did not amount to time travel. You couldn't use this effect to change the past.
I... uh... didn't understand any of it then and I don't understand it now.
According to the Physic's laws, we can travel through the time. But, practically, it is still unreachable.
Finally, maybe we will do it!
You can see into the past or travel into the future without creating any logical causality paradoxes. But if you can see into the future or travel into the past, you do. So logically it might be possible to see into the past or travel into the future, but not see into the future or travel into the past.
