Paradox
Time travel backwards isn’t possible.
If you could, I believe in LOST/Futurama time travel rules that you can't change any of it and just fulfill the past instead. Something would stop you in your quest.

But you can slow it down, which is awesome and crazy.

There is a set of twins, one an astronaut, the other works for mission control of NASA. The astronaut leaves on a deep space trip traveling at 95% the speed of light for ten years. Upon returning the astronauts clock has measured ten years, so the astronaut has aged 10 years. However, when the astronaut reunites with his earth bound twin, the astronaut sees that the twin has aged 32 years!
So by simply flying around space really fast, you'd be flying into the future.

Lots of people don't realize this has been experimentally verified - it isn't "merely theory". It's been done IRL.
Of course, sending a person into space at light speed isn't at all practical, so we do something that is - use a particle accelerator to speed up radioactive nuclei to around 99% of light speed.
Because the particles are radioactive, they have a known half-life. And it turns out that the half-life of the accelerated nuclei is slower by exactly the amount predicted.

I’ll ponder this tomorrow

they, can't - i subscribe to more of a multi-verse theory. Whereas you can go back in time to a similar alternate dimension / universe, but going back in time in your own dimension / universe is paradoxical.
Forward in time in your own universe is a different aspect.
