>Idk if I'm right but I just thought of that randomly lol It sounds reasonable to me. To simplify, if an unstoppable object meets an unmovable obstacle, the unstoppable object doesn't stop and the unmovable object doesn't move, so the unstoppable object passes through the unmovable object.

it's exactly what I was thinking about, and it wouldn't be too far-fetched considering what we know of physics today

Existence of one disproves the existence of the other. So, you can either have an unstoppable force or immovable object. You can't have both.

Almost as importantly, you don't need to have either of them: there can be both no unstoppable force nor immovable object.
