The propagation of gravity is something neither i or many others have even been aware of. Even the thread and the article are titled in such a way to say "Gravity travels at the speed of light" not the propagation....which is later mentioned in the article. It's completely ass about face.....lol

The article was quite obviously talking about the speed of gravity, as in it's propagation, not the force of acceleration exerted on an object by it.

The title isn't misleading either.

Then once we saw that the sun no longer existed (since the lighted had stopped reaching us) we would stop orbiting, since space-time would have reverted to a flat-state. Its cool, but also insane. It means technically speaking, we would orbit NOTHING for about 8 minutes.

Yes.

Also rules out a bunch of hypothetical FTL communication ideas.

Gravity is just the physical influence of string theory. Each atoms thread tugging other atoms.

This is a very elegant way of desribing the (poorly written) article.

All in all it all means almost nothing at all...
post #46 of 192
To make long story short, if we could introduce a mass object one light minute (the distance that light needs 60sec to travel through) away from your gravity sensors, you would experience a reading change 60 sec after the introduction of the mass object.

i.e. gravitational reactions travel through space with a finite speed, and not instantly.

I guess the most accurate method of measuring the speed of gravity is to find a way to make a large massive object simply APPEAR out of nowhere and see how long it takes for nearby objects to get pulled towards it.

Incorrect. We've been able to refract a straight line of light and deflect itself into itself using a prism, and shorting out the light, yet, still maintaining a single band on the trace where the diorama of the prism is hit by that beam.

Single step processing will soon dissipate using one transistor at a time. The parallax of this being that we're nearing 3nm processes for processors, and if we can maximize gravity distribution and electron flow, they don't necessarily equate to the same thing in omnipotent space, therefor, if we can make solid state capacitors and board stock or containment mainboards for our new oncoming potentiometric devices, we can put foresight into techtonic movement and update a large volume of seismic equipment.

Of course if you did jump off your diving board and were travelling at the speed of light your mass would be infinitely large and you'd go completely through the earth. You might get 10 points for it too thumb.gif

That's the acceleration of mass on Earth, not the speed of gravity itself. The speed of gravity is the velocity at which the acceleration of mass takes place
