Could This Bold New Technique Boost Gravitational-Wave Detection? (space.com)
Slashdot reader astroengine writes: One of the most expensive, complex and problematic components in gravitational wave detectors like the Laser Interferometer Gravitational-wave Observatory (LIGO) — which made the first, historic detection of these ripples in space-time in September 2015 — is the 4-kilometer-long vacuum chambers that house all the interferometer optics. But what if this requirement for ground-based gravitational wave detectors isn't required? This suggestion has been made by a pair of physicists at the University of Maryland, Baltimore County (UMBC) who are developing a method that could allow extremely sensitive interferometers to operate in the "open air."
Their work, published in the journal Physical Review Letters, uses the weird quantum properties of light to counteract interference from turbulence in the air to allow interferometer measurements to be made. Their method, which is a variation on the classic Young's double-slit experiment, has been demonstrated in a tabletop experiment — but gravitational wave scientists are skeptical that it could be scaled up to remove sophisticated vacuums from their detectors.

Dear slashdot editor,
Fuck you and your fucking clickbait-style headline.
I have read neither the fucking summary nor the fucking article because fuck you.
kind regards,
Go fuck yourself.

Clickbait buzzword headlines. Jesus christ Slashdot advertisers, I mean "editors."
Hopefully this will also prove that the Electric Universe is real.
No, the Electric Universe is virtual. The real universe is not electric but rather wind-up. The spiral galaxies are the springs which store the wound-up energy. The universe works like a gigantic cuckoo clock. With cables and weights winding up the spiral galaxies.
Instead of pine cones for weights, the universe's cables are connected to the turtles.
There have been papers published recently that prove that it is real, but everyone in Physics ignores them.
But unfortunately, the authors were short on cash, and needed to use the papers to roll their smoking materials.
However, the papers read like the authors were smoking before they wrote them. Which raises some interesting questions about the direction of the Arrow of Time.
I don't think the Arrow of Time points forward or backwards.
It points somewhere to the side.
Schroedinger's Brexit: The UK is both in and out of the EU at the same time!
Interesting. In the Age of the Internet all things are equally true. Clearly I need to subscribe to your newsletter.
If long straight vacuum chambers are required, why not combine this with hyperloop? We could cut the funding for this boondoggle in half, give the remaining half as a grant to Elon Musk, save money and get hyperloop faster and cheaper. Everyone wins.
The apparatus won't very well be able to detect electrical universe phenomena if it's designed not to, now can it.

Actually "time flies like an arrow". According to Groucho Marx.
"and", he added, "fruit flies like a banana".
Call it troll if you will, but my gut reaction is to either ignore clickbait-y headlines, or snark about them, and not about the summary.
Because clickbait never matters.
Nor do editors who won't edit but strive to come up with the stupidest clickbait-y headlines to insult our intelligence with.

No. it's become clear that the universe is imaginary. How else do we explain religions by a sci-fi writer who wrote "the best way to get rich is to start a religion", and politics from someone who wrote the art of the deal is to "tell people what they want to hear."

This is not a new method, the Handbury & Brown effect (https://en.wikipedia.org/wiki/Hanbury_Brown_and_Twiss_effect) sensitive to the the Bose-Eisntein statistics of pairs of photons has been demonstrated in the 50's and used to measure the diameter of stars because the technics is insensitive to the atmospheric turbulence.
The irony here is that after reading your comment, I learned something new, gleaned from a virtuous and vigorous clickbait immune response.
Maybe half the esoteric physics I know I've learned from clickbait demolition.
Likewise, not that long ago, maybe half of all neurological knowledge could be tracked to a skull-ripping dumdum hand-me-down from the grisly aftermath of the Eastern front.
Just like the hyped up loop. Well just ignore everyone that says it horrible impractical to maintain a vacuum in hundreds of miles of tube. Or make some bullshit claim that 1/1000 the pressure of atmosphere isn’t a vacuum.
Isn't there an app for that?
Interesting. In the Age of the Internet all things are equally true.
Yep. This means that finally, in the Age of the Internet, you can finally be right about something!
SJW n. One who posts facts.

What?
Vacuums are pretty simple by definition.
systemd is Roko's Basilisk.
... anybody?
It little behooves the best of us to comment on the rest of us.

I've actually come across some explosive evidence that shows why it is being ignored by physicists.
It's a big pile of worthless fucking shit.
Apparently.
I do not want your cheap brainburning drugs. They are useless for work. And I am a working man today.
Hyperloop gets you mad huh? lol.

Just launch them into space, there you have a lot of space
