So here is a theory that I wanted to share with you about time travelling. Yes I spent about 2 hours thinking about it which I really shouldn't have but hear me out!
So you know how when you travel in space there are light years. I'm not into that concept because I haven't researched it but but! Imagine if those light years are actually equal to some time of billion decades, right? So well imagine if when travelling with say a spaceship and you go, say 3 light years away and then the planet, our planet gets hit by a comet, and it's not there anymore. So well imagine that said spaceship goes back those 3 light years soo that would be 2 billion decades. Sooo isn't that considered time travelling? Because like that planet will already be building up and be all new and ****?

It's much easier to go forward in time than backward in time. In a vacuum, nothing is faster than the speed of light (670,616,629/mph). Time slows down the faster you go (but only for you), so if you could accelerate close to the speed of light you would actually be travelling into the future, so the further you travel the further into the future you will be.

Going back in time is more complicated, but possible, than going forward in time. First, a machine would have to be invented that could go back in time. That first machine would mark the beginning of travelling back in time, so you wouldn't be able to use the first machine. The next machine would have the ability to go back in time only as far as the first machine was invented, etc.

As I said, you can only go back in time to when the first machine was invented that could go back in time. All time before that is not accessible. Thus the only way to save the planet from being destroyed by the comet is if there was a machine already invented that could go back in time before the comet hit the planet.

Which if the comet goes by after 1 billion decades, there is a huge possibility that we are safe from the comet?! OMG we are genius!
