Gravity waves possibly detected for the first time ever

[Ripster42]

Does this mean they've detected gravitons?

No.

[Xada]

Just because you interpret it as such, doesn't make it so

Science is not rumors... And everyone should love science!

Eh, Science provides interesting possibilities and technologies. I think that's the part of science people like, but science also demystifies everything making everything seem pointless. The show Rick and Morty plays with this fact a lot, having Rick deconstruct love as just chemical reactions that compel animals to breed or how bout when Rick took the time to explain mathematically that Morty and Sommer are pieces of shit all the while they are minutes from ceasing to exist. They even just go to another reality where they had just died, buried themselves from that universe and took their place as if nothing ever happened.

gravitational waves are real!!!

pretty nice glad it's actually true

[Ripster42]

I'm not into politics.
I just don't agree with the news delivery method of todays papers.

"The sky MIGHT fall down tomorrow and we got a machine 3x more sensitive to prove it". Cool hum.

I would be extatic if there were ACTUAL results published.

A couple of Ls that each have ~2mi long legs on either side of the earth with lasers in the that measure their length. When gravity waves pass through them one leg gets smaller while the other gets longer. They have to be so big because the change in length is tiny.

What are you talking about? What events do you think produce detectable gravity waves? Because it's pretty much just colliding black holes.

From the locked duplicate thread.

Right now these are basically only things we can detect. I recall reading that it may be possible to detect g-waves from neutron star collisions too, which are probably more common. Even then to my understanding, we may be able to detect these waves coming from colliding black holes and those then pass trough things like galaxies and stars and also note that these are gravitational waves from black holes. They get altered along the way and thus allow us to measure what happened to them along the way. Also, if inflation theory is correct, there should be gravitational waves left from when universe expanded just after it came to existence.

[Ripster42]

Funnily enough, the Bicep2 experiment thought they had detected g-waves, but turns out it was just dust fucking it up. So you are 100% correct in thinking that, this is why LIGO will quadruple check everything before coming forward with any findings. If they have discovered something, we probably won't hear about it until the end of the year.

Not just dust, but people parking in the parking lot. The shit is incredibly sensitive.

They should fine 10% off all research costs to researchers claiming they might have found something. Either you find something or you don't...in any other case they can go f themselves.

You're talking about accurately sensing variations in things that some of the most sensitive instruments in the world are just barely able to detect that they exist.

Right now. Technology advances. Better detectors will be possible to build. Even now we know we can probably extend the range of detection 3x.

This video mentions things we could do, if we are able to see g-waves (that specific part is at about 4:40). Anyway, I'm not going to argue this with you any longer.

The data plots look pretty spectacular.

These black holes are larger than would be produced by a supernova of current stars with high levels of "metals", but early stars in the universe could have produced them.

[BuckSparkles]

Something neat you would see in a science article.

Doubt I will ever benefit from this discovery though. Maybe the generation after.

I like the power that went into creating those gravitational waves: 3 solar masses were used in making those waves, and gravitational wave luminosity peaked at 200 solar masses per second.

Easily, I was just responding to someone who said something like "sounds like dust could produce a false reading" which ironically has produced a false detection for g-waves before Hell, I think they said a truck driving down a road miles away or a bird farting could produce a false reading if they aren't careful.

That experiment, LIGO, cost a billion dollars.

That's a lot of money.

Let's hope it'll be worth it. Teflon anyone?

A sad day for physics cranks everywhere.

They're not claiming that they might have detected it, they're claiming that they have. They've spent over half a year convincing themselves that it wasn't an error; it was detected in September.

Money well spent. One of the most basic properties of the universe has been confirmed to exist!

I saw this comparison:

The energy of the merger is to a megaton of TNT, as a megaton of TNT is to a single molecule of TNT.

Are you repeating the myth that Teflon is a NASA spinoff technology?
