where were you when gravitational waves were confirmed?
>where were you when gravitational waves were confirmed?
Well last time I was taking a dump, coincidentally I was also taking a dump when it was announced that the majority of the signal they detected was likely just dust. This time I'll probably be on 4chan, but I'm going to try and keep the tradition going and be taking a shit when they announce this one as well.
This pls. trips demand it
Also holy shit 100k viewers. I'm laging like shit did I miss anything?
HOLY FUCK IT'S ACTUALLY TRUE
This is the biggest scientific discovery in my lifetime. I am so excited right now, I've even called my sister. FUCK. I love you /sci/entists. I love all of you.
Yeah, the Higga is probably a bigger deal, because it requires the alteration of things like the SM Lagrangian, as opposed to a confirmation of things we already theorized and had worked out.
Good job humanity on showing how great 1% of us are and also how fucking pathetic 99% of you are
Actual question from someone who knows a little bit about relativity.
How can gravity waves escape black holes? EM waves are pulled inside because they have energy - and according to GR, if I understand correctly, gravity affects energy and not mass (which still works with mass because E=mc^2)
So gravity waves have no energy? But how is this possible?
Or maybe I was wrong, gravity does not 'work' on energy nor mass, it just bends space-and Gravity waves are part of space, not something inside it.
F = GmM/r^2
F = ma
a = GM/r^2
The event horizon of a Blackhole is the r such that the a = c and thus nothing can accelerate past it. Gravitational waves are produced outside the event horizion.
>Gravitational waves are produced outside the event horizion.
OH thank you. That's what I've been missing.
I really don't know enough about GR so my understanding of gravity waves is limited.
Again, thx for the explanation.
Uneducated plebian here, excuse the ignorance.
What does this mean for quantum physics?
Doesn't quantum physics not mesh well with relativity because of they disagree what happens around black holes? ( I believe Hawking radiation is one of the problems)
Is quantum physics disproven?
No not at all. This has little to do with quantum physics as a whole, although it does support some niche aspects of it like "is there a particle that carries gravitational waves?".
This is just finding the last missing piece in Einsteins general relativity that we predicted but couldnt evidence.
Can someone link me to the downloadable pdf of the actual paper regarding gravitational waves
I like to dream yes, yes, right between my sound machine
On a cloud of sound I drift in the night
Any place it goes is right
Goes far, flies near, to the stars away from here
Well, you don't know what we can find
Why don't you come with me little girl
On a magic carpet ride
You don't know what we can see
Why don't you tell your dreams to me
Fantasy will set you free
Close your eyes girl
Look inside girl
Let the sound take you away
So, basically what I'm getting from this thread was that this is pretty much already known, and in no way affects our everyday lives. Thanks! Saged, and hidden.
We can use this confirmation to create a new breed of astronomical "gravitational telescopes" that will allow us to detect obscured events and measure stellar masses to extraordinary degrees of accuracy.
It also points towards several other fields of research, most notably quantum physics which now must start the search for the "graviton" in earnest.
>where were you
I was in my classroom with all the rest of the AU physics department, watching the livestream, popping champagne bottles and eating cupcakes, listening to my professor greg harry talk about the day the detector went off
Where DeGraes or Havcing, they must explaining this shit , for what I pay to them?
You seem to have made a bit of a mistake in your post. Luckily, the users of 4chan are always willing to help you clear this problem right up! You appear to have used a tripcode when posting, but your identity has nothing at all to do with the conversation! Whoops! You should always remember to stop using your tripcode when the thread it was used for is gone, unless another one is started! Posting with a tripcode when it isn't necessary is poor form. You should always try to post anonymously, unless your identity is absolutely vital to the post that you're making!
Now, there's no need to thank me - I'm just doing my bait to help you get used to the anonymous image-board culture!
You seem to have made the mistake of assuming I give a fuck! The truth is, I do not. Therefore, you are now free to pursue more productive endeavors than following me around on a forum to bitch about the particular way I post.
No need to thank me!
Haha, very funny, faggot. Now shut up and let's talk science.
Manipulation would be unlikely. You need truly massive objects moving with high acceleration to produce these effects.
Better understanding of gravity? Yes, we can test general relativity more carefully against the other competing theories of gravitation.
Also we now have a way of probing astrophysical processes which doesn't involve light, neutrinos, or cosmic rays. This will have implications for cosmology.
god this shit gives me chills just looking at it

eating my cereal and giggling on 4chan at how excited the physicists relative to how confused the media and everyone else is:

Uhhh... we're just physicists guys, we can't answer those 'hard' questions (trollstein.jpg)
