Black Hole Squarks

[Rev. Green]

When two black holes collide they emit a "squark" of gravitational waves. Why? There is conservation of mass, centre of mass, and angular momentum. I assume that tidal disturbance transfers angular momentum to internal components. Do the gravitational waves arise because of relativistic effects, in a similar manner to magnetism?

Rev;
Conservation of mass? I suppose so, but it's not certain, is it?
Conservation of centre of mass? Yes, I guess, if conservation of stuff is accepted.
All this is well beyond me, but could you give me a clue about relativistic effects and magnetism?

Atheist and TTT - Please leave this thread alone if you can't provide an answer to the question.

Thanks for the warning, Secret...
Gosh, I always presumed that suspension was for disgusting behaviour, not for drifting from the original question.
Have a good evening.

ok SM, here's the real answer:

Sorry, Atheist, it is many years since I calculated magnetic fields from first principles. I seem to remember that Newtonian mechanics gave a zero field and something else was needed, which I now guess was relativity. I'm probably wrong.

rev the answer is in my link above.

I think they're called "chirps" rather than "squarks", which to me means "supersymmetric partners of quarks" and is a different thing altogether.

I'll get back to this. But, disclaimer: My General relativity is generally not so brilliant, so it might take a while to understand the answer myself before I even get around to typing it.

There is a difference between having the right to remove posts, and it being wise, considering the friendly atmosphere one might require between participants.

No need to overthink this. The chirp 'heard' from colliding black holes is simply an audio analog of the propagation of the accelerating expansion and contraction of gravitation waves caused by massive bodies as the revolve faster and faster around each other before colliding.

//I think they're called "chirps" rather than "squarks",//

Maybe the OP meant "squawks"?

Corby; Thanks for the Rule 16 post.
