I just realized that if you logically go step by step through the process of time travel, it ends up making no sense at all.
Going backwards in time:
If I go back in time, I'll be able to see myself. Lets refer to the person that went back in time as X1 and lets refer to the person's past self as X2.
Now, based on a linear understanding of time (otherwise this would be alternate universe traveling instead of time traveling), X1 can only exist if X2 goes back in time. So, in this scenario, X1 goes back in time and sees X2.
Two things can happen:
X1 stops X2 from going back in time, creating a paradox.
X1 allows X2 to go back in time. So, now we have X1 and X2, both individuals who went back in time, however this is where the issue arises. Wouldn't this mean that there needs to be an X3 figure? This is, of course, impossible because that slot has already been taken care of by X2 for X1. This means there would be no past self for X2? How did X2 get there?How does X2 even exist?
So, this scenario either poses a nonsensical idea of infinite regress that would break time, or is nonsensical from the start.
Going forward in time
the idea of going forward in time makes even less sense.
Say I go 10 years into the future, If I am able to see myself in the future that would mean there is no free will. Also, it is paradoxical because how can I exist in two different times? this is either alternate universe traveling or a broken concept. lets again use X1 and X2. X1 referring to the guy going into the future and X2 being that same guy's future self.
if X1 sees X2 10 years in the future, there is no logical explanation (in the sense of linear time) that X2 can exist. He can't exist. There is no lead-up to his existence. If X1 goes into the future, briefly sees X2, he is forever stuck in the future because the aforementioned issues of going back in time still persist.
So, can time travel exist? or does it actually just mean alternate universe traveling?
