Does anyone have a theory or a way, even SURE it's imaginary about time travel? 
I'm not going to say we're going back to the dinosaur era, no.
But if we just want to go back in time for one hour. How can we? 
opinions?

Create an overload in the warp plasma conduit. This will cause a subspace fissure to open up, and bob’s yer uncle.

Close your eyes and use your imagination.

Well... the only 'Real' way I can think of is possible "Paralel dimensions'... Where the alternate reality for what ever reason is experiancing 'TIme' at a different/slower rate and hence is 'behind us' in events.

I think I read somethng by Pratchette? Maybe a New Scientis? that time travel is not possible because of the 'Matter can't be created or destroyed' thing.

Effectivly you'd be taking 'Matter' from 'Here', effectivly 'destroying it' and thence putting it back 'There', hence 'Creating it'.

Not sure if I understood the idea completly or even remembered it correctly.

Still, cheers.

Not at work.

Whenever I do that, Halle Berry interrupts me.

The only way would be by a perfect simulation.

Very powerful (quantum) computers could one day calculate positions of every electron in the universe from the beginning of the universe to the present, so you could watch any time in the past and present. Like dinosaurs or cavemen. Or watch what is going on in present on other planets in other galaxies.

There was recently a TV show, "Devs", that explored this idea where they have a quantum computer and watch sex between Marilyn Monroe and Arthur Miller.

First hop over to another universe where time goes in the opposite direction to ours. Wait one hour, then hop back.
