Let me blow your mind for a sec (I have obtained obscene amounts of knowledge by just thinking)
I'll Start With The Basics:
Do you remember that one time you ate a duck in Finland with Drake???? Oh, so you don't?? It very well could have happened it just isn't affecting you right now, because it is not in your head, but it is possible that it still happened. SO you could be a murderer, and I could be a bee in disguise......just think on it. ALSO, if you remember reading this, you will know that your future self remembers it, because YOU remember it, so, if we remember something, that means that our future self is alive, keeping that information that you have now.
Onto Time Travel:
If you where to be able to time travel, why wouldn't you have seen the machine yet? If the person where smart (as I assumed they would be, because they built a time machine) they would have gone back to tell other people. if they where able to warp time, are they able to warp space and dimension also? If so, the error rift would be too great to surpass without experimental genocide. And figuratively, if they somehow DID get to the other time, they would have no way to get back.
Now, that THAT part is cleared up, lets go to how it is completely IMPOSSIBLE.
You know inches? Yea, do you see them walking around? NO! because they don't exists, therefore, cannot BE. They are a unit of measurement, that only exists in our heads, same with time, hours, seconds, and years are not persived by animals.
Now, try imagining swimming in a river that isn't there, impossible, same with time, because nothing can be created or destroyed. (even if there was time as a thing, what would it be made out of?)
The 'Now':
Going back to what I said erlyer, your future self remembers for you. SO if you get a sense of deja vo, it is probably your future self explaining to you......If you die, wouldn't your memories be wiped?
Some Other Stuff:
If you are made up of cells, and there are single celled organisms, and they obviously have memory, are you a full being, or just an army of collective concense. 9sorry for the miss-spells)
