"What happens when an unstoppable force meets an immovable object?" is actually quite easy to answer after asking exactly one additional question:
"What is the coefficient of restitution for the proposed collision?"
For e = 1, the immovable object becomes an unstoppable force, and vice versa.
For e = 0, the two merge and proceed in the same direction at half the speed at which the unstoppable force was originally moving.
For -1 < e < 1, the rest of the universe is obliterated by the energy released.
For e = -1, the two pass through each other without interacting (this is the only case in which the mass of either may be finite).
