2.Mathematics and Time .
Those who are keeping tabs of modern physics are aware that Time Travel is theoretically possible, though modern physics can not reconcile certain facts.
Those who have read Isaac Asimov’s “Eternity’ and seen some of the Hollywood Films on Time,like The Moth man Prophecy (based on True life story),’Next’ will know that by extending the Logic of these films which are correct any way), one can see the contradiction.
If one were to travel back in Time , meet his self at that point of time and kills him /kill his mother ,Grand mother before (the man in who travelled to the past) before they were responsible e for his birth, what happens to his existence now?
If Time travel is possible, we can also alter Time.
When we alter Time we are altering Events which have happened already.
