Anyone excited about tomorrow's announcement concerning LIGO's findings???

VERY!! !

Question to all readers - What, if anything, can GWs be used to test or probe?

Radar is used to measure speed, for egs. ...it is a wave being used to acquire data about an object.

Can GW be used in an analogous fashion?

Currently, there is no known method to artificially generate measurable gravity, so artificial gravity waves seem to be out of the question.

For now.

Like it or not, we're still a tech level 7 civilization. Tech level 8 is when you might see such things as sustained nuclear fusion, autonomous robots, gravity generation and control, and routine travel to and from Ceres, Luna, Mars, and maybe even the outer satellite worlds.

I hope to see these things in my lifetime; but I won't bet the farm on it.

This explains it as well as any article I've seen.

It will be the same as it was for the discovery of the Higg's boson. The next Nobel prize for physics will go to these scientists...

Rare are things that get me exited, that's one of them.

Time for someone to post the video of the Beach Boys singing "Catch a Wave and You Feel On Top of the World".

This is a corroboration of Einstein's General Theory of Relativity that had to wait for the technology to show it. Einstein's
G.R. still on point....

It's a shame he never knew just how correct he really was.
Hard to imagine a single human with a greater impact on Science.

As someone who has finished physics, I find Einstein's contribution to be somewhat overrated. If I was to pick the greatest physicist of all time, I would settle with.... Max Planck or Richard Feynmann.

Einstein laid the groundwork for all 4 of the major thrusts of physics for the twentieth century. And he published all four papers laying this groundwork in a single year. Just the scope of his discoveries is enough to rank him first among equals...

He did not lay the groundwork for them all. What about quantum mechanics?

I'm not a physicist, but I've seen and heard several times from purported experts that his 1905 papers laid the groundwork for them and this certainly included quantum theory. To quote Wikipedia, Einstein's theories for the photoelectric effect extended the quantum theory which Max Planck had developed in his successful explanation of black body radiation. So, even if not quite foundational, it certainly help refine and lead the way.
