What would happen if an unstoppable force hit an unmoveable object?

Then ... and only then ... people would stop repeating questions like this and "what came first, the chicken or the egg?"

no.  air friction will limit it's terminal velocity.  It'll still hurt, and possibly kill if it strikes someone

The unstoppable force deflects to whatever side easiest for it to deflect to, but if you say they meet exactly head on they will merge. The unstoppable simply decays into it's anti-particle counterpart and passes through the unmovable without moving it.Neutrinos with no mass and no charge probably are the unstoppable forces in nature that we know of.Dark matter and dark energy excluded.

In a vacuum, both objects will land at the same time.

The laws of physics say that an object in motoin will remain in motion unless acted upon by an outside force.  It's hard to conceive of anything that would make Earth's core stop spinning short of some planet destroying catastrophe.

There seems to be a missing varible of time. Without a time contraint there is an infinite number of times these balls will touch. I am not sure the minimum distance from the wall though. I guess it would have to be at least smaller than the size of the small ball so the two would actually collide.

well somewhere in the middle you might become weightless as you would be in the center of a spinning mass. but most likely you would get to a point that the gravity would push you back. just like on a merry go round getting to the center is actually pretty hard.

One of two things will happen:\n\n1) The so-called unmovable object will be moved.\n2) The so-called unstoppable oject will be stopped.\n\nThis existance of an unstoppable object precludes the existance of an unmovable one, and vice versa. Of course, it's likely that neither one exists anyway so the question is pointless.

Yes. It will superheat and have a violent reaction when something touches it.

The answer is C. Although B seems to be a possible answer at first, there could still be an n-number of forces acting on the object such that the sum of all the force vectors is zero, thus making C the more complete answer. One of Newton's laws says that F=m*a (force on an object equals its mass times its acceleration), or a force of 1 Newton on a 1kg object will make it accelerate at a rate of 1m/s^2 in the same direction of the force.

It theory it would destroy the body... and the rest of the universe. In relaity it's simply impossible.\n\nAny object travelling at lightspeed has infinite mass. That in itself isn't a problem, except that to decelerate a mass in any way you need to apply equivalent energy in the opposite direction to overcome inertia. An infinite mass has infinite iniertia. So to decelerate and mass will need to apply infinite energy.\n\nI've read some really good speculation on what would happen when a FTL mas hits something. It seems to come down to two camps.\n\nThe first camp says that the bullet can't be slowed down because has infinite iniertia and thus will always continue on its way. But the body it strikes has to absorb some energy from somehwere if it is to remain stationary. Through some methaemetcial gobbledegook it's apparently possible to arrive at a solution that the bullet will pick up the body and accelerate it to the same speed to avoid the problem. That means that the clothes are also accelerated, and the ground under its feet etc. Instantly the whole universe attempts to accelerate to lightspeed, which means that evertyhing is at the same energy level: infinite. Equal energy levels,  no energy transfer possible, instaneous heat death. By by universe. We all cease to exist.\n\nThe other school suggests that the bullet can't help but be decelerated. Yes it has infinite intertia, but the body has some iniertia too, so any interaction has to result in some energy loss from the bullet. Some energy loss/infinite kinetic energy = infinite energy. The interaction requires more energy than the noverse contains. Once again, instant heat death.\n\nThe trouble is that massive objects can only achieve lightspeed in theory, so we can only speculate on what it would be like. But the math says that any attempt to slow it down will require more energy than the universe actually contains one way or the other. It's an impossibility but if it ever could happen the universe couldn't continue to exist, at least not in its current form.\n\nWorrying about what happens to the body is a minor detail. The body will die with the universe.

If the unmovable object is not unbreakable, it WILL be broken. \nI believe this is an unanswerable question.

simple. 'every action has an equal and opposite reaction' remember that one? the unstoppable force will do a 180 degree turn and apply itself in the other direction.

Don't worry, this will never happen. The "gravity" of the earth is actually caused by attraction between two objects of significant mass.  Were the gravitational force of the earth to vanish, that would mean that the earth itself had vanished.  It would also mean that you would be in free-fall, expereincing what might appear to be weightlessness.  not that this would matter considering that you would be in the void of space and would be dead.

Nothin would happen.\nIf you consider two bodies the earth (name it E) and a large mass (m). \ninitially M rests on E. and you lift mass M. the force used to lift it will also act on E.\nAlso if you consider the mass M and E. as a system force exerted on dropping M would be internal and since internal forces do not cause acc. the Earth will not get unbalanced.\n\nThats good for us isn't it...

Well my friend, two theories come into play here.\n1) Things in motion tend to stay in motion.\n2) Energy cannot be created or destroyed\nTherefore, one or both of the objects (depending of the structure and integrity of the objects) will suffer severe or absolute damage as the transfer of kenetic energy to solid matter occurs. (Depending on the speed and velocity)Whether you think so or not, one obect will move or one object will stop.

depends on the direction of the force
