If had a top and could spin it an infinite speed what would happen?

it would disappear... (as per the the current physiscs theory we have..)  it would go to the future :)

It would change the Earth's rotation and the Earth would tilt on its axis. What if all of us asked the same question at the same time that violated one of  Yahoo's community guidelines? Would the system completely break down?

well if it were in a medium where it is obstructed by external forces,it would continue till the 0 point and stop... but when unobstructed it would keep travelling.

Spin.  Spinning machines make thead.

Ok, say the earth was all solid and there was a tunnel from one side to the other.  \n\nYou would keep accelerating as you moved toward the center of the earth, until you reached a very high speed.  As you passed through your speed would be at a maximum.  Then you would begin to decelerate as you went toward the other side.  Neglecting friction and air resistance, you would have just enough momentum to make it up to the surface on the other side, but you would have to grab on or else you would fall back into the hole and go the other way.  You'd continue oscillating back and forth forever if you neglect friction.  \n\nBut of course in real life you would slow down a little bit each time.  Your motion would be like a kid on a swing set, or a pendulum, a gradually decreasing swinging motion until finally you come to rest in the center.

it would be the exact same speed!  \nhere is an example. --------\n--if you are swerving on the road and going 50 mph. and then you stopped swerving, you would still be going 50 mph

Sorry, no.  You'd splat at the bottom of the hill in real life.\n\nThe reason for this rests in a physical law that says if you're going straight, you'll continue straight (down hill) until a force stops you from going straight.  Spinning is not that force.\n\nThe momentum (which is the thing that keeps you going straight) is linear (straight).  Spinning is angular (it goes around, not straight).  So the forces required to start spinning are not straight (they act over angles) and will not affect your straight march into that wall at the bottom of the hill.\n\nOf course, if you simply fall down, the ground pushing on you as you hit it is a linear force.  Your linear momentum will be changed (stopped in this case).  Thus, it will in fact stop you on your downward destiny with that wall at the bottom of the hill.\n\nI tried to keep equations and such out of this, just the one notion: momentum will keep you going straight downhill until you apply a linear force (not angular like spinning) to stop your run.

The universe, from your reference frame, would be length contracted into a single plane perpendicular to your direction of motion, thus enabling you to cross it by traveling no distance. Time for you would be stopped completely, thus you would travel this no distance in no time, at a speed of precisely c in your reference frame (light does that in every reference frame), despite the fact that by definition you are stopped in your own reference frame. Every other light ray would also travel at c in your reference frame and so would pass you in a finite period of time, except time would never move forward and so it wouldn't actually go anywhere. If you looked outside at the infinitesimally thin slice of universe, you would find that the area no distance ahead of your light ray is in the future of the origin (as viewed from any valid reference frame) and the area no distance behind it would be in the past. The beam you are riding on would have no frequency and would appear as a constant electric or magnetic field. Since the beam you are riding on is still traveling at c, it would therefore have infinite wavelength and so the field in question would permeate out to infinite distance in front of and behind you - not that it matters because there is no universe in either place. Speaking of the universe, every particle in it would appear to you to be infinitely massive and the universe would thus collapse on itself infinitely fast, if only there were time for it to do so.\n\nBy the way, there is a reason the speed of light is not considered a valid reference frame in special relativity. This is it.

ok, it would freeze quickly (not explode-it is made of solids and liquids, which don't expand in vacuum). But for fun, assume it doesn't freeze or die of hypoxia.  Since there isn't any air, there is nothing for the wings to beat against, so it would flap it's wings and just stay in the same place- The motion of the wings might cause it to start rotating, though-so I would imagine the fly (which is a magic fly that doesn't dry up, freeze, or need oxygen) would just spin around in a tiny circle right where it is.

You would have to overcome the spinning motion of the atmosphere.  See my answer to your "if the world stopped spinning" question.  So yes, if you could reach about 900 mph going west, you would be counteracting the spinning of the Earth and eventually be somewhere else "without moving".  Now about the Earth's orbit around the sun...

If there is no wind speed, no other gravitational pulls present, no magnetic interference, and you throw it perfectly perpendicular up, then it will fall at the same place.\n\nIf you are riding in the passenger seat of a car going 20 mph, and you throw a ball out your window straight out, the ball will have an initial forward speed of 20mph.\n\nThe same concept applies in your question.  Let's say when you look up, the earth is rotating to the left.  When you throw the ball in the air, its initial direction will go a little to the left, but you won't notice it cause you are going a little to the left as well.\n\nHopefully that helps a little bit.  It's a little hard to explain without pictures.

I would have two large, EXTREMELY LARGE balls attached with a rather large string or steel cable or whathaveya. I would throw one ball in space and BAM it goes on forever!\n\n~or two quote someone, until it hits something.

spin around really fast

you would get electrocuted plain and simple...you wouldn't go flying through the air unless it was a really high voltage...I'm pretty sure.

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.

Thrusters would do the job, or the center can counter rotate. Thrusters could rotate the whole assembly or a motor, attached to a  massive central hub could cause the thing to spin while the angular momentum of the hub is going the other way.\n\nOnce you get the thing rotating, you don't really need to keep it going except for the occasional thrust once in a very very long time. Why? because I assume people inside will be moving around, that will alter the angular momentum, but very very little.

It spins roughly at the speed it orbits earth. I believe there is a slight "wobble" in the spin which enables astronomers to see about 3/4 of the moon over time. \nIf it spun at the same speed as the earth, the spin would have no effect on earth, but it would cause the moon to get hot inside because of the tidal effect. \nThe tidal effect acts like a brake.
