hollywood time travel paradoxes

[boiker]

back to the future:

At the begining of BTTF, marty's family was dysfunctional, and his dad was a dweeb.

if marty went back in time only to almost screw things up with his mom and make his dad a stud, wouldn't his life been like it was at the end of the movie; before he went back in time?

If marty got his mother to fall in love with biff and not his dad would he even exist in the first place to cause that to happen?

i know.. i'm a dork..

it's friday

The Law of Transit Displacement would protect Marty McFly from the changes made while time traveling. Very major changes did affect him (for example he almost disappeared from existance because his parents weren't meeting each other correctly).
