COLUMBIA, Mo. – Scientists have attempted to disprove Albert Einstein’s theory of general relativity for the better part of a century. After testing and confirming Einstein’s prediction in 2002 that ...

More precise measurements would be needed to lower the margin of error, but the astronomers claim "You can rule out a speed of gravity greater than twice the speed of light with a high degree of ...

SEATTLE -- Einstein was right. The speed of gravity matches the speed of light, according to astronomers who took advantage of a rare planetary alignment to measure one of the fundamental forces of ...

Time has an arrow: It only ever seems to move in one direction. The future is always unknown to us, while the past forever remains locked and inaccessible. And yet, the vast majority of the laws of ...

We may not know exactly what gravity is, but at least we know how fast it moves. We may not truly know what life is, but we can still look for it on other planets. "This is one of the most fundamental ...

Quantum physics is often described as the most successful scientific framework in history. In its 100 years of existence, it has explained everything from the periodic table of the elements to how ...

The first step toward quantum gravity, the "holy grail of physics," may be hiding in a quantum recipe to cook up black holes. That's the suggestion of new research that adds quantum corrections to ...

The speed of the wave propagating along the string is the speed of gravity.<HR></BLOCKQUOTE><BR>I think your string analogy would work better if you make the string very long and instead of "yanking" ...
