The paradox i know about traveling back to time goes like this:
Consider a person X ,and Y as his girlfriend.
1. X comes back to 1999 from 2010 and tells the X living in 1999 that X should not marry Y because in 2005 Y will dumb X and will leave X depressed for 3 years.
2. So if X is now aware of the information and doesn't marry Y how can he come back from 2010 to 1999 and save his past self.
I thought about this and what i think is this:
*If there are an infinite no of realities,each with its own possible outcomes not dependent of the other realities.
*Then X could've come back to the past X from one of the realities in which Y dumps X.(Every reality doesn't necessarily have to have the scenario that Y dumps X because every reality is different.)
*The past X doesn't necessarily have to be in that specific reality from which the X from 2010 comes and warns past X.
No more paradox?
I probably did something dumb in doing so though
