OK Answer Time:

The unstoppable force ( object ) would either go through the immovable force or it would go around it.

Like when neutrinos hit me or the Earth, they just pass through. Or light going through the sun, it might get detoured but it keeps on going.

Or it might go around like light bending around the sun or the wind going over and around the mountains.

While thinking about this I couldn't imagine anything immovable really. In fact it appears that movement itself might be one of those unstoppable forces. Maybe the expansion of the universe is also unstoppable,but then again it may stop.

Best to all,
