This rather suggestive image to the right (rather like some of these paintings of flowers which remind the viewer of something) is actually an artistic interpretations of gravitational waves.

It may appear as underwealming news but gravitational waves have been detected and scientists are hi-fiving and getting their knickers in beaudacious knots all over the world. Science has published an article which you can read here.

It involved a team of over 1000 scientists and was the first tentative proof of a theory Einstein and others developed half a century ago.

I also wanted to blog this today, so I'll connect your post into mine (which will tie in other topics). I agree that it's scientifically historic.

Here's a nice (if lengthy) summary that came out last year, before it became official:

Yes Pope! Awesome!!!

I believe that this was the last testable prediction for General Relativity, so ALL of the predictions have been proven to be accurate, so, its a lock.

Pretty heady stuff.

:D

We now have the possibility of gravity telescopy, which might allow us to "see" dark matter and energy:

Gravitational telescopes could even allow us to study the gravitational waves left over from the Big Bang. This method of detection would also allow physicists to better understand black holes — which don't radiate light but are thought to radiate waves of gravity.

"If you look with visible light as far as we can look in the universe, the universe is no longer transparent; it becomes opaque," Burgess says. "Almost nothing is opaque to gravity."

Of the discovery, Burgess says, "It’s not the end of something. It’s the beginning of a whole new kind of astronomy." (source)

As cool as it is that someone can actually build an apparatus to measure this...I think, given that GR had passed all its other tests, it would have been bigger news if there had been something unexpected about this.

Scientists have actually been expecting this.  It's when you get an unexpected result, like Michelson and Morley did, that it gets really interesting.  (For those not in the know, it was the Michelson Morley experiment that led towards special, and then general relativity in the first place.)

@Unseen, yes, indeed.  Dark matter is genuinely a mystery at the moment, and hopefully some pieces of the puzzle will fall out as we build better and better detectors.  (Now that we're certain that there's a point to doing so!)

It was called an "Observatory" from the get go because it WAS assumed that the waves would be found, and, the true mission/objective would be to now be able to make new observations using it.

So, yes, CONFIRMING the existence of gravitational waves was ground breaking...because until that point, it WAS only theoretical...but the last prediction of General Relativity remaining to BE proven.

The real benefit, from this point forward though, will be the new knowledge we gain from a new window on the universe.

Every time we add a new way to see what's out there, we discover more about how it all works.

:D

Maybe "the God particle" will allow us to see faith waves!!!

Comment by TJ on February 13, 2016 at 12:14pm

LOL

No one theorized Faith Waves yet....perhaps you could prepare a paper for us?

I think the best way to get Faith Waves would be to hijack spacetime, and call it godtime, and then say as god is everywhere, when he moves, we get Faith Waves.
