Is 'Back to the Future' scientifically possible?


Published: 21Oct2015

It’s 'Back to the Future' day: “In Back to the Future Part II, Marty McFly travels to October 21, 2015, to save his children, yet to be born in Back to the Future's 1985.” (Source: CNN)

Journalists looking for comments can talk to Alex Maloney, professor of physics at McGill:

“Back to the Future was a great movie which brings up many interesting scientific issues.  Although Einstein's theory of general relativity seems to allow time travel under very special circumstances, it appears that the effects of quantum mechanics make time travel impossible.”
