So Folks, would you like to travel through time like Marty and Doc? Personally, I’d give anything to see what the future looks like… But maybe you'd want to go into the past to change something? Unlike the Back to the Future movies, it is actually thought that by changing something in the past, you would create a different timeline, a new "branch" on the
big tree of time that would add to an infinity of other alternate realities that already exist.
