The vast majority of scientists consider time travel impossible.
Hawking's Chronology Protection Conjecture (amon many other works) covers it.
What is once observed as having happened will have to be undone in order to rewind or "travel" in time, or would be altered if preceding events were.
There's no reason to believe this kind of violation of basic causality could ever occur.
