FFS, like. I'm so stumped on time travel, like, I don't even know why I have thoughts.
But, I'm just like one day, laying in bed and crack, and suddenly, it's like:
'So, if Time Travel's real, then so is infinite universes! Like, a universe where we hadn't TTed!"
And then I'm like, "Wait a second ... Wouldn't there also be, like, a universe where I had four toes, or three, or etc. On one foot and then on another—wait, what about 1,000,000,000 toes on one foot." And then start counting the universes in which I have 99,999,999 toes, or 99,999,998 toes and then I'm like, "GASP, MY HANDS TOO!" And begin to count.
But, THEN, I'm like, "So if my future self came to warn ME, did someone come to warn HIM?! WOULDN'T HE REMEMBER THIS CONVERSATION?! DID HE JUST TALK TO HIMSELF, OR DID OTHER HIM TALK TO HIM?!"
So, basically, my mind's just like, "Woah. I'm blowned."
