Any Physics Freaks?

The Arrow Paradox

Zeno’s arrow paradox appears to show that motion is impossible.

It works by taking a snapshot of an arrow at a point (either in space or in time) in its flight. At that point, and at every other, the arrow is motionless. If there is no point, spatially or temporally, at which the arrow is moving, though, then the arrow is motionless. Contrary to appearances, an arrow in flight cannot move.

If we had a film of the arrow in flight, and broke it down to its individual frames, we would see that in each frame the arrow is simply hovering in the air. It is only when you put all the frames together that the arrow appears to move. In each frame, i.e. at each point, the arrow is motionless.

This is true irrespective of whether we think in terms of time or space.

Motion occurs through space, not at a single point in space. To move, something must get from one point to another, and so at each point considered individually, the arrow is still.

Similarly, motion takes time, it doesn’t occur instantaneously. At any specific point in time, therefore, the arrow cannot be moving.

If at every point and at every moment in its flight the arrow is still, though, then how is it possible for it to move from the bow to its target? If the arrow is made of wood at every point in its flight, then it must be wooden; it can’t be plastic. If it is sharp at every point in its flight, then it must be sharp, not blunt. Similarly, if the arrow is motionless at every point in its flight, then it must be still, not moving.

Contrary to appearances, then, arrows cannot move towards targets. In fact, similar reasoning applies to any other alleged case of motion, so it seems that movement in general is impossible.

This only works through a single frame of reference (in this case a camera). To presume something is true only by viewing it through one frame of reference is nonsensical. The coloring on my TV is screwed up. Near as I can tell, the Colts wear bright green uniforms. If you slow down a Colts game on my TV and watch it frame by frame, the uniforms are green in every frame. Clearly the Colts wear bright green uniforms.

This example is not nonsensical. It's showing that sound logic bears faults when applied to pragmatic study. A paradox is created by the evidence provided and the causal outcome of actions.

The point being made by examples like this is that our understanding of the universe is incomplete and our methods of science and mathematics cannot empirically prove the phenomena of our world.

Mathematicians can prove that mathematically one body can never pass another body regardless of their velocity and/or acceleration. We know this to be untrue.

Dig deeper, man.

Um. . .what?

You gotta be kidding me? Critical thought is an emasculate trait? f**k me. I guess I am suffering from chronic vaginitis, then.

Or you could just stop wearing yours on the end of your neck, for that asinine statement ;-)


ANother flaw in the arrow paradox is that it gets us to accept the concept of a point as a tangible reality, when the 'point' is a mathemeatical abstraction. An arrow never meets any point, because points don't exist.

ahh, but my young grasshopper, you are assuming that space is granular!

what if space-time is continuous? :)
