If this experiment checks out, it will probably be the most famous discovery of our lifetimes...

It's been a long time. Gravity waves are starting to seem as rare as TV shows from extraterrestrials.

I just noticed the date on this thread. I just saw it and assumed it was posted today. I was starting to get excited Sad

Sorry. I've been ressurecting old threads. I was curious to see what was posted so long ago, and to see how much has changed in 3 or 4 years.

He said the very high-precision measurement was the first to check whether Einstein's assumption about gravity was correct.

"Thankfully, it is," Hogan said [under the assumption that gravity had been measured to propagate at the speed of light], adding that were it not, theorists would have their hands full trying to explain the result.

Wait a minute...Hogan's comment doesn't make sense! If gravity travels at the speed of light then it is mediated by a boson (the graviton) and the field theory for gravity is a contradictory alternative to Einstein's general relativity.

LISA and the search for Einstein's waves

But even with the startling advances the new generation of scientists has brought us over the past few years, and the promise of so much more to come, we should not overlook the fundamental, ubiquitous yet all but universally overlooked contribution made to science by Hurley Smith.
