So LIGO results get published tommorow. Probably. How many of you have your GR up to scratch enough to read the paper?
bump.
interesting
This will happen:
- half the theoreticians will see their pet theories buried alive
- the other half will try to find more evidence for being right
- string theoreticians will yet again dial another set of knobs and exclaim this fits well with their existing framework.
I confidently ignored the waves chapter in Wald back when I had my GR lecture. I probably should read up on it when exams are over.
>>7848431
what is there to read?
Either they're detected or not, what paper could you write about that?
>>7848853
You're a fucking idiot.
Nobody doubts the existence of gravitation waves, it's taken for granted on all mainstream theories.
I agree on the string theorists shit though.
>>7849471
Most people here don't understand gravity waves in the first place and the paper will probably have some background on them.
>>7848431
Oh shit forgot that's tommorow
On a similar GR, note, when is the event horizon telescope gonna take a picture of *A ffs
>>7848853
I refuse to believe that anywhere close to half of all physicists' pet theories are directly at odds with GR.
>>7848431
If anything, I'd imagine the statistical techniques they used to prove that it wasn't just noise will be the crucial part. The general relativity part is basically universally agreed upon.
I don't think we'll be able to say it's been proven scientifically, anyway, until the other detectors around the world get up and running and reproduce the results.
It's only science if it can be repeated.
>>7849521
so is climatology a science?
>>7849491
>Most people here don't understand gravity waves
You're one fucking idiot.
This is all about gravitational waves, not gravity waves.
Why do retards talk about stuff they don't understand? i'm sick of this place.
how do you even measure waves that are as weak as this?
>>7849707
two possibilities:
-You just got trolled hard and took the bait like a fucking tuna
-You're getting mad at someone for whom english isn't their mother tongue.
Does LIGO deal with ligand-activated intracytoplasmatic transcription factors?
>>7849771
How about
- A retard who doesn't even know physics and elementary stuff such as GR read about LIGO's upcoming announcement on a popsci site and came to /sci/ to talk bullshit
Will anti-gravity happen in my lifetime or not nerds? I expect to average out another 45 years.
>>7849855
No.
>>7849839
>assuming that /sci/ isn't said popsci site
fuck off pretending to be smart and elite, you're an idiot and nobody cares
I bet you even think your 3.9 gpa makes you smart.. haha.. ha.. ha.. i remember when i thought that
>>7848853
you see this all the time as a result of scientific revolution -- the clarity of valid results affirms one single thread of thought, the content of which becomes so obvious, as is the case with any effective solution, after the fact -- and the majority of the speculative research that never quite went anywhere, done with defective methods, done mostly to satisfy a personal whim or to take up time to satisfy tenure, is annihilated
>>7849956
I love my 0.9 GPA
>>7849539
have you seen the curriculum that climatologists take? its almost as bad as biology
>>7848853
>- string theoreticians will yet again dial another set of knobs and exclaim this fits well with their existing framework.
salty because his theory of everything doesn't explain everything
Step it up, pleb
Undergrad at UWM here. A bunch of my professors work with LIGO and are hyped as fuck. Half the staff is gone and the few that are here couldn't stop smiling. It was pretty funny to watch.
That being said though, judging by how they were acting (we are holding a livestream of the conference on campus) it seems like this will be a huge announcement.
>>7848431
What are the implications of this discovery? I mean, could this impact future space exploration in anyway?
>>7850122
>future space exploration
we are not going anywhere soon, go to bed.
>>7850084
You're in high school right? University level biology is not all "memorization" like it is in high school. On the contrary, you do need a knowledge of chemistry and the labs require you to understand and apply concepts not just memorize them.
>tfw i should have gotten a physics major instead of computer science so i can understand this
Oh well at least i can pay the bills
I'll admit to being totally in the dark about all this
Can someone give me a summary or link me to a reliable source so I can read up on Gravitational Waves and the implications their existence would have on... well... stuff

If this turns out to be real, would this open up another possibility of observing the universe? So instead of observing different wavelengths we could now observe the universe via gravity?
How exact is this? Did the big bang emit these waves?
Is this going to revolutionize astronomy, or is it mostly going to impact the theoretical side of things?
>>7850627
It will be a new astronomical observation tool
All:
Anyone have a working link to thevpress conference?
Any idea where the paper(s) will be? arXiv or some paywalled journal?
>>7850631
>It will be a new astronomical observation tool
sweet
I take it if you place multiple detectors on earth, you could triangulate the source of these waves?
>>7850636
There are two stations now and yes, they can determine the direction of the source.
https://en.wikipedia.org/wiki/LIGO#Observations
>>7850640
What about the source of the direction?
>>7850636
The problem with earth based detectors, is the interference (obviously) the next gen will be space based detectors.

>>7850682
>http://arxiv.org/abs/1602.02809
No that's not it. The paper will have the full LIGO collaboration as authors.
>>7850774
anti-gravity is the repelling force something creates when it has negative mass.
I'm pretty sure it's impossible to create a substance with negative mass, unless the object in question is traveling at negative speed/negative the speed of light, which is itself impossible.
basically, don't hold your breath on anti-gravity.

I'm out.

everyone already believed that gravitation waves existed (cause the math works). Now, we have solid proof that they exist, and possible applications of this discovery.
>>7850974
THE BABY BUCKET CREATES THESE WAVES IN SPACE TIME THAT WE OBSERVED. WE COULD TELL. IT KILLED THE MAMA AND DADA BUCKET, BUT IT CREATED A RIPPLE, SO THERE'S THAT.
>>7850979
My nigga. Took a GR class with Dr. Shoemaker, who was a pretty big part of all this.
What does this even mean? Is this some shocker to people?

gravitation waves detected consistent with 2 blackholes merging into one.
>>7850978
https://www.youtube.com/watch?v=c7293kAiPZw
>>7850984
So if gravity exudes characteristics of waves, does that mean it is quantifiable, as per the graviton, for instance?

where were they detected?
how did they get the blackholes?

lel too bad
>>7850996
On both LIGO detectors.
Blackholes are astronomical objects predicted by GTR and we have plenty of evidence they exist. The signal detected matches theoretical simulations of what will happen if two blackholes merged into one thus the logical conclusion is that the gravitational waves detected originated on an event where 2 backholes merged.
How can they calculate the distance from this data?
Rainer Weiss sounds a lot like Feynman I like it
>>7850995
I don't know. It's very possible, but having concrete proof of something we already 'knew' existed wouldn't make research any easier.

It is the result of 40 years work and that paper builds on 100s other papers related to theory and technology. Many other papers will follow but this one presents the result concisely.
Are you the guys trolling the chat room in https://www.youtube.com/watch?v=c7293kAiPZw
does this mean we can make gravitational radiation based communications? Do the gravitational waves get reflected by matter? Do they travel at c through all media?
scroll down for those wave audio files, sounds like out of a movie

They're extremely weak tho.
>>7851167
>does this mean we can make gravitational radiation based communications?
yes but it won't be very economical given that you need to merge two black holes to get a single blip.
Did that fucking journo just try to accuse them of plaigirism? What the fuck.

In theory yes, but practically you'd need to shake 2 blackholes to create waves powerful enough to be detected, so no.

>>7851135
As far as i know, different kinds of waves (with a slower period, triggered by different kind of events than bh mergers), and with much much more accuracy because of the huge fucking baseline
