Thanks for clearing that up. I was wondering why my balls were clanging.

Even scratching your balls creates gravitation waves. It's just harder to detect than blackholes.

Two black holes colliding? Bannon and Trump?

Just checking in. This is the worldline where Marilyn Manson is president and Trump was just crushed by two giant pistols, right?

Given how long gravitational waves are, I can't see how you'd notice. No need to secure the china cabinet, everyone.

Maybe this will knock us out of the Trump news cycle time loop we are stuck in....

While this article is both old (we had a thread on it a couple of days ago) and not the first detection of gravitational waves, I think it's always worth noting what "detect them" really means

LIGO measures the change in length of two "arms", set 90 degrees from each other.

Each arm is 4 kilometers long

During a gravitational wave detection, they change length

By 1/10000th the diameter of a *proton*.  Across 4km

And we can detect that change, reliably.  It's one of the most astonishing feats humans have ever managed

/Should have gotten the Nobel last year.  If they don't get it this year it will be a huge WTF moment.

The Perseus cluster black hole's B-flat...is 57 octaves below middle C or one million, billion times lower than the lowest sound audible to the human ear.

Glockenspiel Hero: /Should have gotten the Nobel last year.


The detection announcement last year was after the nomination deadline; although only by a week or two. This year, I'd imagine they'll win. My guess is Kip Thorne for half, maybe Barish and Weiss for the other two quarters. We'll find out soon.

Ahh, I thought it had been before.  If they don't get it I'll be astonished.

Medicine needs to go to CRISPR.  I was wondering if they are just waiting on all the lawsuit fallout.

October 3. Kip Thorne is a near lock. I hosted his colloquium at wayne state a couple of weeks ago. That'll likely be the last talk he gave as a non-laureate... Besides being so unbelievably smart, Kip is also a very very nice guy. Here's the video I made of the talk (LGT YouTube)

When I called in sick on Friday, I said the extra gravitational waves were the reason. They told me to go ahead and not bother coming in the next day as well. What a bunch of swell guys.

The graviton, if it exists, is supposed to be tiny, though, right?

Leonardo Dan Vinci June 11 1514. From Italy, but Pope Julius II was his benefactor, dying just before the fateful trip. Pope Pius X almost kiboshed the trip before being convinced by the Medici family it was better to be remembered as pro science... So Rome?

It was first determined to have an extremely small maximum mass it has to be less than 7.7 x 10-23 electronVolts by - get this - LIGO's first 3 observations.

"Black hole A leaves the Sagittarius galaxy traveling at .093c. Black hole B leaves the Andromeda galaxy traveling at .13c. Answer the following questions:
1. How long will it take them to collide?
2. How far from the midpoint of the two galaxies will they be when they collide (round to nearest parsec)
3. How far away do you want to be from them when they do?

Yeah, he actually sent me this video.  Was just at the World Feline Congress, chilling out with the human in the B&B he's renting for the week.

He also tells me after he flies back that he's going to be visiting his old littermate at the bodega and wants to know if he can pick you up something.
