Gravitational Waves Detected (Finally)
« on: February 11, 2016, 06:45:22 pm »
This is big news on the astrophysics front. After years of looking and designing ever more sensitive detectors, gravitational waves have finally been actually detected and they seem to be pretty much as Einstein predicted about 100 years ago. Next step: gravitational telescopes. ;)

I'm sitting here, shaking my head and mumbling to myself in awe. This article gives an excellent perspective--much better than some of the headlines I've seen, which talk about scientists listening to the sound of 2 black holes colliding. I guess that's the glamorous headline--and it's pretty cool in and of itself--but it misses the real import of this development: We now have a new way to observe the universe, one that isn't dependent on the electromagnetic spectrum. Holy. Shit.
The first song sets the wheel in motion / The second is a song of love / The third song tells of Her devotion / The fourth cries joy from the sky above
The fifth song binds our fate to silence / and bids us live each moment well / The sixth unleashes rage and violence / The seventh song has truth to tell
The last song echoes through the ages / to ask its question all night long / And close the circle on these pages / These, the metamythos songs

As a measure of how important this is, the article published in Physical Review Letters is 16 pages long -- in a journal that normally limits articles to 4 or 5 pages.

I was talking to my husband about this last night. He is thoroughly freaked out; I am excited to see where we take this discovery. Either way, it is the definition of awesome and amazing.

And according to several online pieces, Einstein has been 'vindicated'.  

Which is funny, 'cuz I didn't know his credibility was in jeopardy.
You have my sword
And my shield
And my... um... slacks.

This is one of the last major predicts of his relativity theories that had not been verified -- so that makes it news in itself.

True.  I just chuckled at the word choice.

The day this happened, I was singing off the highest rooftops and got goosebumps every time I told someone about this.

Most people looked at me like I had a goat's head, but that's okay.  The news talked about it, but they don't understand the implications of it.  (I just got goosebumps again!)  We just took the tiniest of steps into the new future.  We have now seen with the tiniest of blips on a man-made machine what was before the theoretical.

What we can learn just as observations (more goosebumps!) and what can happen when we can use gravitational waves or even create them....

We got to see the beginning of the future and it won't be realized for generations to come.  But we were here to witness it.  (I'm still rubbing my arms.)
