What would happen if an irresistible force collided with an immovable object? Would time itself stop? Would there be an endless transfer of energy? Or would Isaac Asimov be correct in that "a universe in which there exists such a thing as an irresistible force is, by definition, a universe which cannot also contain an immovable object. And a universe which contains an immovable object cannot, by definition, also contain an irresistible force."
Fortunately, we don't have to wonder any more thanks to a recent physics experiment carried out by Justin Bieber, playing the part of the irresistible force, and a revolving glass door, temporarily playing the part of an immovable object:
As you can see, it all works out pretty much how you'd think it would!
