Yes, I agree about the energy question, but I talked to a PHD student about the subject, by amplitude I mean the amount space is stretched/squeezed relative to itself, I have also read in the link you've sent me it consists of 2 components with an angle of 45 deg relative to each other. But what...
I honestly cannot filter the answer out of that paper, my physics skills aren't good enough for that yet. I talked to someone about it but he said the amplitude didn't change. Also I read somewhere that energy is conserved until (part of) the gravitational wave is absorbed. The second part is...
So I'm trying to understand something about the Hulse Taylor Binary. Here they talk about the change in periode that actually changes with the period. So what does Pt mean here?
And what is actually being explained? P1year also makes no sense to me. Is that the period after one year? And what...
I'm confused about how the predictions of this graph were formed.
I have this formula:
But the change in frequency per second is about : 2x 10^-12 which has a problem because when you multiply this by 10 years you don't even get a change of frequency of 1/1000 of a second and in the graph it...
What properties have to do with the frequency at which the lengths change of the arm?
Also does anybody have a body paper or webpage which explains the properties at a detailed level?
In the paper Advanced LIGO they published some figures with chances. I would like to know how they know that there's a 90% chance for something to be in a specific value.

I have some questions about the first discovery paper that was released about gravitational waves, especially some of the maths.
How did they:
1. Calculate the masses of the black holes that merged
2. Calculate the energy radiated away in gravitational waves
3. Calculate how far away the event...
