How long would it take? (Physics question, sort of. Maybe) (page 2)

Finally-Free

It would move forward instantly, and would probably knock me on my ass, but it would take me a year to realize it.

I'm more intrigued by the rocket engine on your ass. Is that rocket solid fueled? Was that rocker strapped on or was it a standard sphincter mount?

I disagree with thoes of you that say it will take a light year to move. The rod exists in physical space at the begining and end of the light year. Therefore when you push the rod at the begining of the light year the ending of the rod will be moving simultaniously although it will be a light year later. The act of moving an inch will not take an entire light year. There, will however be a light year between the recorded time of the movement between the two ends, plus the time of the whole atomic shockwave affect (if measurable).

Also, if you and the other person pushes the rod an inch at the same time, both ends would move an inch, and it would take at least 1 year before both end were back to their original position.

Oh! I like this one. What would happen? With Else's wave thingy, would the waves just pass each other somewhere in the middle and not really be anything cool? Or would they do something neat?

Gary, the engine has been surgically implanted in my left buttock. That's why I tend to sit a little off center. (Hopefully this will quell those damn rumors! Perfectly legitimate explanation.)

According to a "relativity explained" book I have, if you were to put a pulley on the surface of the moon, and could somehow have a perfectly taut and inelastic length of rope extending from the earth around the pulley and then back, then if you were to pull down on one side of the rope, there would be a 2.7 second delay before the other end of the rope would raise up, which is the distance from the earth to the moon and back again in light seconds. So according to this explanation, the "impulse" travels at the speed of light, but no faster.

But that makes me wonder what would happen if you pulled down on both sides simultaneously. Perhaps as the impulse met at the center, the two ends would instantly spring back to their starting position.

Well if your correct DanTheMan, you just shot my theory all to hell. Thanks

Dave, with the rocket engine in the left buttock location, wouldn't that create a right power pull?

Darth Yhwh

Yeah, you would think that he would just fly in circles.

Think of it like this:

If press on a rubber ball, you can see it squish. If you press on a steel ball, you cannot see it squish. Why?

The atoms in the steel ball are more tightly packed together than the rubber ball, however, the steel ball will squish a tiny, tiny, tiny, bit. If you took an really powerful microscope and viewed the atoms when you push down on them, you would see them move?

Another analogy is this:

Get 50 domino's standing in a line, adjacent to each other. Then push the one. Would the domino at the end fall immediately? NO, you would see the wave move through the domino pack until it reached the domino at the end. Atoms work like this. The wave through the pack is the information. That traverse of information can never exceed light speed. So, the end of your rod can never move before one year. The density of your rod explains how fast this wave information can traverse through the rod, one atom at a time. The denser the rod, the faster the movement.

PS. there are so many double entendres in that statement

ROFLMAO!!!!

Gary said "sphincter"...
