Backwards time travel is physically impossible. You would need to travel at truly negative speed to achieve it, but the magnitude of speed is always positive.

Stop trampling on our hopes and dreams, it's all we have left.

Correction: You'd need to travel with a speed higher than the vacuum speed of light.

Thinking about it, it's even more complicated than that. You're right that a negative speed would not work since the square of a negative number is positive anyway. But a speed higher than c would result in a negative square root, so no real solution. Also, traveling at exactly the speed of light would divide by zero lol

But maybe our formula is wrong. Or it's just impossible, who knows?

Whoosh material right here.

Edit: Apparently OP is making a joke. Mmmhmm

Imagine assuming the other party didn't get the joke in the pic but just chose to ignore it, just so the dumb reddit meme can live on!
