If you replace "contradict" with "agrees with" and "instantaneous" with "constant", he'd be right.

Way to be an ignorant fucktard. Gravity travels at the same speed as light. It seems instantaneous in the same way that light does.

Gravity propagates at the speed of light. That is, the changes in the gravitational fields caused by the motion of the masses involved radiate out from the system at c. This is an expectation of General Relativity (the formula E = mc² is from Special Relativity) that has been explicitly confirmed by observing the orbits of binary pulsars. The observed decay rates of these orbits exactly agree with those predicted by the action of gravitational radiation in the form of waves.
So the gravitational field is always present, while changes in it propagate as gravitational waves (not gravity waves, which are something different), and at the speed of light.

Thank You Supersport, Einstein is spinning so rapidly he's generating enough electricity to power several small towns.

Holy cow! Who would have thought that the scientific community could get it all so wrong and yet be able to still accomplish so many amazing things? I'm glad SS is here to put it all straight.

Goosey - I haven't read all your comments, but you seem to have forgotten quantum entanglement as well.
If you've included it, I apologize, but if you haven't, it's pretty damn interesting.
Basically it says that two quantum particles - specifically photons in the thought experiment - can exist millions of light years apart, but behave as though they are the same particle. This would suggest a FTL transmission of sorts between the two to regulate the behavior.

Be nice if you knew anything about the subject. I don't, but then I am not deciding whether one of the most important discoveries in scientific history is correct or not...

Uhhhhh, why do people just make up random shit?
8/18/2007 7:01:04 PM
@Bob Dole: Because they accept the Big Book of Made Up Random Shit, AKA the Bible, as literally true (after numerous mistranslations and scribal errors), and hence at some level feel justified in making any sort of random shit and claiming that it is as true as the Bible.

fuck wits like that should be pushed off a 100m tower to remind them of the folly of those who follow false physics.

You know, we practically hand ammunition to the fundies when we respond to topics that we don't have the proper knowledge to respond to. If you haven't studied or practiced (or aren't currently not studying or practicing) physics, cosmology, astrophysics, etc., please keep your mouth shut. Otherwise, you'll end up as a post on www.lstdt.com.

-E=mc2 says nothing about things travelling. It is the formula for the conversion of matter to energy and vice versa. The speed of light happens to occur in it because of principals of the universe involving light speed and how matter functions at high velocities.
-gravity does not travel, any more than any force travels. But our observations of it would be limited by relativity.
-incidentally, while relativity does not contradict the laws of gravity, it does contradict (slightly) earlier theories of motion. Can't recall which one. Basically because the formulas for motion get warped slightly at high speeds. It's called PROGRESS.

Frank: Particles (electrons actually I think) can be made to travel faster than the local speed of light - light does slow down when not in a vaccuum. If you fire an electron beam through some water you can get a neat halo-glow effect as the electrons, travelling slower than the absolute speed of light, yet faster than the speed of light in water, create an effect similar to a sonic boom.
I wonder about that Jupiter gravity experiment. I'd have to see more details than were in the article.

I'm familiar with the principle of quantum entanglement, but don't know enough about it to really talk about it (although if that doesn't stop supersport, maybe it shouldn't stop me ;) ).
It's interesting, true enough, but I think it's a special case rather than a general rule, isn't it?
8/19/2007 10:08:52 AM
Yeah, pretty much. But if the implications are true, it's pretty detrimental to the case of the "no such thing faster than light", which anyway isn't what relativity, much less E = mc^2, says.

Why is Einstein automatically wrong and Newton automatically right?
8/19/2007 8:02:34 PM
Ahh supersport, you always manage to put a smile on my face... and then I cringe when i realise you aren't joking...
Also gravity instantaneous? WTF? What could possibly make you think that? Do you intantly hit the water when diving into the pool?
8/19/2007 11:39:24 PM
That may very well be the most retarded thing I have heard in my entire life. Where do people come up with this shit?
8/20/2007 1:06:13 AM
Gravity is instantaneous? on earth it's 9.81 m/s^2....3x10^8 m/s is the speed of light. Given the fact that terminal velocity for humans on earth is about 53.6448 m/s (120 MPH), you can easily conclude that gravity is not instantaneous, and 300000000 > 53
8/20/2007 1:20:53 AM
KibblesandBits - gravity is always propagated at the speed of light. What you're referring to is [i]acceleration[i] due to gravity. It's a whole different ballgame.

I openly admit that I did not take a college physics course.
Everything I know about physics, I learned in high school or through self-education.
I can still say, with all certainty, that supersport is so wrong that the physical laws of nature may actually refuse to apply to him, just to avoid being associated with such idiocy.
