My rant on time travel:
some say it doesnt exist because if it will we would have already visited ourselves right?
I think that they do and there are specific reasons why we havent experienced time travel yet my reasons follow:
A: you can only go forward in time
B:you cant go to before the time machine was built or you were born. EX: a person would get younger until they broke down into protiens and amino acids, and the machine would turn into raw metals and dust.
C:we realized the problems that backwards time travel and decided as a people to only go forwards in time and return with more advenced technology therefore accelerating evolution and humans trancending to some thing where time travel was no longer necessary.
ANOTHER PARADOX: if you went back in time for a specific reason, say to give your self the cure for cancer, your goal would already be accomplished and you wouldnt have a reason to time travel. agreed?
