[Spacedaily] Scientists find evidence for speed of gravity

post #1 of 192

Quote:
Chinese scientists revealed Wednesday that they have found evidence supporting the hypothesis that gravity travels at the speed of light based on data gleaned from observing Earth tides.

Scientists have been trying to measure the speed of gravity for years through experiments and observations, but few have found valid methods.

By conducting six observations of total and annular solar eclipses, as well as Earth tides, a team headed by Tang Keyun, a researcher with the Institute of Geology and Geophysics under the Chinese Academy of Sciences (CAS), found that the Newtonian Earth tide formula includes a factor related to the propagation of gravity.

Now we are only years away from discovering that the speed of light is the fastest anything can go because they haven't overclocked our processor yet. lol.

Well, now we know that collapsing stars wouldn't alter the course of the Nexus fast enough for the plot of Star Trek Generations to be plausible...

Also rules out a bunch of hypothetical FTL communication ideas.

Not the acceleration due to gravity, the speed at which the force of gravity travels. Ie how long it would take for you to feel the pull of the mass of an object if it was spontaneously created.

The distance covered per unit time of a (Currently theoretical) graviton.

Whenever they can't find a speed of something: "give em' travel at speed of light statement"

I've always wondered if gravitons travelled faster than light. I was hoping for something controversal like that.
