Dr. Emmett Brown: Precisely.
Marty McFly: Whoa. This is heavy.
Dr. Emmett Brown: There's that word again. "Heavy." Why are things so heavy in the future? Is there a problem with the Earth's

gravitational pull?

[somberly]
Marty McFly: which is what makes time travel possible.
[Doc opens the door and looks at Marty with a stunned look on his face]
