In theory, if an unstoppable force meets an immovable object, they'd cancel each other out. Then add just one more thing and then the unstoppable force is stoppable and the immovable object is movable. This is just theory, because no such forces or objects exist. At least...not that we know of.
Actually, a physicist was talking about this. He said if you had a literal unstoppable force (also known as infinite force) and an immovable object (known as infinite mass), they would pass right through each other, neither affecting the other.
I heard that too. lol That's more of a paradox answer to the "equation" of the situation.
Likely they would just both merge together because pressing against each other with infinite and equal opposition would mean either would let down, and since they can't just ghost through each other, they would be compressed together and become a new object. An infinitely compressing one. lol
Unless they really do shove through each other molecularly but seems like that would weaken both of them, making them no longer unstoppable and immovable. lol
That last frame, what she is doing with her hand, is there any English/American "story" behind that gesture? Because the first thing I thought of was this [link] old Danish TV series where one of the characters does that gesture while saying "Bob-bob" and suddenly every Dane started doing that! Even though there is absolutely no word in the Danish language which has a resemblance to "bob" (soundwise). I'm just wondering, does anyone else do that? Sorry for that long text-block but I am just mighty curious about similarities and differences between various cultures..!
No, normally the phrase to go along with that gesture is, "So-so". If you are asked, "So, how was the tour?" And you thought it was a little boring, you'd say, "So-so," and do this little hand gesture.
So, take for example if you were to punch a rather light ball. Your fist would be a moving object, right? And after you hit the ball, the ball moves. On the other hand, if you were to punch a brick wall, your hand would be moving but the wall would be immovable to your fist(ie it doesn't move from the force of your punch). If, however, you were to take an object that cannot be stopped to an object that wouldn't move ever, what would happen?
This happened in a greek myth. There was a hound that would catch anything that it hunted and I think it was a small deer that could never be caught. Some idiot sent the hound after the deer and they went on a loooonnnggg goosechase. Zeus couldn't decided what should happen (should the deer be caught or should the hound not catch it's prey?) and he got such a big headache trying to decide he just turned the two into stone so he wouldn't have to choose.
