What do you think?
Time travel is an often debated topic and more than ever with new theories regarding E=mc2 and the beginnings of our perceivable universe. And when the term “perceivable” is used here it refers to our capability to comprehend time or lack thereof. We may not be able to comprehend it at all. So what would happen if we time traveled backwards? This physicist sure proposes an interesting scenario given such a phemomena:
It’s a common trope in science-fiction novels: Astronauts travel back in time by zooming through space at speeds faster than light (usually getting into trouble in the process).
Most physicists think that scenario is impossible.
But let’s suspend disbelief for a second. If it time travel like this were possible, how exactly would it work?
It turns out that objects traveling faster than the speed of light could go back in time — but in the process, a pair of phantom doubles of the speedy object would pop out of thin air, and one would then go backwards and be annihilated with another, according to one hypothesis, which Robert Nemiroff, a physicist at Michigan Technological University in Houghton, Michigan, described in a paper published in May in the preprint journal arXiv.

It’s a terrible idea. It’s like reversing the motion of photons. And then everything else, all at once.
Backwards time travel is a bad idea? I better stop doing it then.
Worst mistake Sherman and Peabody ever made.
Same with Tommy Turtle and Mr. Wizard.
But if you go back in time and change something then when you get to the present there will be no need for you to every go so you won’t. If you did travel backwards in time we’d already not know cause your effect has already happen in this present
time isnt a linear line theres multiple differant timelines time branches off from each and every action creating a multitude of branched outcomes to time travel without altering the future one must find a timeline not linked to their future but to a differant past that has a differant future or its future has not been decided like it stopped at one moment because nothing was done to decide its futre leaving it at a perpetual loop until its future is decided
When has it ever been a good idea?
Yeah, but those damned memories make it so hard
