There is nothing crude or disgusting about this thread. What is this place coming to?

You don't remember your math correctly. Minus infinity is just infinity in the opposite direction. You can't square infinity and you can't square minus infinity. However, if you could they would give the same result, as any negative number multiplied by itself is positive.b0b wrote:If I remember my math correctly, the square root of infinity is -infinity (negative infinity)..."
Remember that the square root of 9 is 3 or -3 ?

It will only come to relative rest. It's on the surface of the earth, which is rotating and moving through space... Nothing in the Universe is standing still.Richard Sevigny wrote:...The swinging pendulum will lose momentum until it finally comes to rest. At that point it is doing nothing.
Hey, we're back to that nothing again.

If your car was capable of attaining the speed of light, you were driving at night at the speed of light, turned your headlights on, would nothing happen?

So in the end which wins.

I guess I was worng. Now I think that the square root of infinity is minus zero.

b0b, don't worry about it, it's nothing anyway.

Minus zero times minus zero is zero, not infinity.b0b wrote:I guess I was wrong. Now I think that the square root of infinity is minus zero.
Give up on trying to deduce the square root of infinity; it doesn't exist. It's like that ancient Greek god who was destined to push a rock up a mountain, and each time he got to the top he found himself at the bottom again.He got NOWHERE.
...which, of course, is a vector version of...
NOTHING.

Something would happen. The guy behind you would see your lights, but you wouldn't. Of course, at that speed you'd be leaving everyone else behind, so it might be many years before your light reached him.Jim Bob Sedgwick wrote:If your car was capable of attaining the speed of light, you were driving at night at the speed of light, turned your headlights on, would nothing happen?
You'd also be at infinite weight, so your gasoline usage would be on the high side. At today's prices you might want to put off that experiment.
...and do NOTHING.

Excerpt from the Paul McCartney Song "Feet In The Clouds"Dave Burr wrote:Excerpts from the Verlon Thompson song; "I Was A Square"
.....you see, I was a square when you were around..... I wasn't cool, I was acting a fool when you were around.....And it just isn't fair, now that I'm not a square but you're not around.
"I've got my feet in the clouds, got my head on the ground
I know that I'm not a square as long as they're not around"...

I think if you were driving at the speed of light and turned your head lights on, some one would try to pass you. Possibly my wife. There's nothing I can do about it.

If they looked at your tail lights as you left,
the closer you go to light speed,
the more that the doppler shift would turn them redder.
BUT after you passed light speed the waves
would truncate like digital sampling.
At some point every OTHER cycle of light would be seen,
and again faster only every third cycle would be seen
But you would still be putting out the regular signal.
Keep going fast enough and your steady light would begin to blink.

Lorentz contraction:
Car and driver would also contract in the direction of travel, approaching the speed of light, approximately one-half at 90%.
The length of this dimension at the speed of light:
NOTHING!

David, wouldn't you have to have a blower on your engine to attain that speed?

No, that's an alternate universe. Warp speed is many times faster than the speed of light. And there are no acceleration and deccelaration effects - people stand around without holding on to anything as their ship goes in and out of warp speed. Also, everyone in the universe speaks English. Pajamas are military fashion. And, named main characters never die, only unnamed temporary characters.Alan Brookes wrote:...and I thought all those years watching Star Trek were just for entertainment....
You might say it's nothing like our universe.
