The wavelength of light is on the order of a micrometer, but gravitational waves only shift the mirrors by only a trillionth of that distance.

Mindblowing sensitivity; they can detect a shift of a trillionth of the diameter of a proton. But even that isn't enough for them. They've tinkered with it and doubled the sensitivity yet again!

Thanks for posting this.

I viewed a youtube recently that remarkably conveyed pictorially like I’ve never seen, a complete vacuum where electrons and even atomic matter just appear from nothing, as long as the anti-electron or anti atomic matter (proton or neutron) appears out of the nothingness with it. It’s very short duration.

Pretty amazing stuff... with obvious links to creation itself.

"Quantum Noise Of Empty Space"

I think that was a Pink Floyd album.

IMHO, we know little, and the current particle physics and quantum mechanics models will not hold up. I love the science, but feel strongly that what should come from all of this is humility. We have no idea why gravity exists, and how it works. We can say things like objects of mass attract each other, but why is that? We can say that chemical reactions that result in a lower energy state are favored, but why is that? Lots more to know - obviously..

That said, Epstein didn’t kill himself..

It’s amazing what some humans can accomplish, while other humans go into a homicidal rage because they didn’t get a ketchup packet in their fast food order.

“Quantum Noise Of Empty Space”

That’s a designation of an EEG of the Democrats.

“detect a shift of a trillionth of the diameter of a proton.”

You’ll be comforted to note that elsewhere in the article it says they only need to detect a whopping “few thousandths of the width of a proton,” on the order of a trillionth of a micron.

A micron is still sizable in many ways. A person can feel texture features down to about 1/100 of a micron in size.

Well, they ended talking about an upgrade to the original, so really, this time, it’s war.

Do they still use red shift for these laser calculations?

"a complete vacuum where electrons and even atomic matter just appear from nothing, as long as the anti-electron or anti atomic matter (proton or neutron) appears out of the nothingness with it. It’s very short duration."

Do physicists still believe that sub-atomic particles consist of energy an not really matter? If so, I can see this may be plausible. I asked another poster if red shift is still the standard for measuring of particles moving away from out perspective. Your input?

I'm still waiting for a confirmed understanding of gravity, and not a math white board. I read some theories, but nothing has been proven by empirical evidence.

Yes, but he/she had nine lives..

And, did Heisenberg's uncertainty principle involve Jesse, or Gus?

My machines here have a repeatability of 1 micron. Unless the sun reflects off a shiny surface too long, or the idiots leave the door open on a cold or hot day, or a hundred other variables.
To detect a shift as small as they are referring to mind blowing to someone in my trade.

Nifty. I wrote a college paper on “squeezed light” near 30 years ago. First time I’ve seen a reference to it since.

"chemical reactions that result in a lower energy state are favored, but why is that?"

For the same reason that rocks tend to roll downhill rather than up (from higher to lower gravitational potential). It is easier to release rather than gain energy because adding energy means applying it in a very specific manner. There are just far more ways for energy to go from a high to a low state. So on average, all energy is expansive.

Intuitively, I wouldn’t think they would strictly need the redshift of the merging black holes in order to determine that a merger did indeed take place - somewhere. All they need for that, is the observation that the two parts of the split wave are no longer in phase. But you know these guys as well as I do... At a minimum, they’re going to want to know where this merger took place. Did it happen a billion light years from here, or five billion? And for that, they’ll want to know the redshift, in my humble, non-physicist opinion!
