The only unstoppable object is an immovable object. They can't meet at all.
Did you mean unstoppable force?
Yes, that is what he means. At least, that is what I presumed what he meant.
In that case, the unstoppable force wins. The result is called a black hole.
no, a black hole is the caused by a star collapsing into its own gravitational field. no external forces are involved.
Counting gravity as a fundamental force and the leftover mass of a star as the immovable object, and considering the compression of neutronium into a singularity as moving the immovable object. A bit of stretch, I know, but still...
I love this discussions it makes you use your brain.
the problem that I see there is that gravity (which is a form of acceleration) would be meaningless without an object to attract, since its a force that can only be applied to the existing object (which is unmovable).... And the star that created a black hole is already in motion, since it is part of a galaxy =)
Perhaps, but if you look at it another way, the unmovable object is the resulting chunk of neutronium rather than the star (assuming a large enough star). Gravity is meaningless without an object to attract, but that essentially means gravity is never meaningless, since anything with mass inherently has self-affecting gravity. In this view, the unstoppable force is the gravity of the neutron star, which is made of the most densely packed matter possible. The immovability, of course, would be the fact that particles cannot exist in the same space, so a particle with literally no empty space cannot merge with another. The fact that gravity has already been enough to overcome the strong and weak nuclear forces should tell one thing, but enough mass and the gravitational force becomes strong enough to move the immovable chunk of neutronium inward, imploding it and leading to that Newtonian logic-defying concept of a singularity.
As for that last part...it kinda ruins the thought experiment when you take into account that there really is no such thing as an immovable object!
