Time travel

So I'd like to travel in time but lack any grounding in physics etc

I've been doing some research on the internets and wondering if I should take some courses at uni or something

SPOILER: String theory is bullshit. But even if it weren't, the extra dimensions are supposed to be all rolled up and invisibly small, so they have nothing to do with parallel universes or whatever you fuck you're trying to say. Yes, the whole theory may be bullshit, but that's no reason to just start making stuff up about it.
