Guys, this thread did not show on the 'unread posts' so I missed it so far. Actually, after havign posted about it n the other thread, I thought to open up a thread here but I find it's already in existance.
Just to express a couple of basic points as I understood them .
1- large masses like moons, planets and starts, in motion, create gravity waves. They are usually long-period, like the moon's tidal waves, at one cycle per month.
2- binary and multiple star systems create gravity waves, caused by the differential pull of the bodies, these are also of the long period kind. A Nobel prize has been issued in the past on the study of a binary pulsar system which emitted gravitational waves (guessed by the maths and not directly detected)
3- Colossal clashes like the recent one produce immense energy which propagates thru the cosmic void by gravitational waves, like ripples in a pond. In black holes collision, no lighwaves propagate, as far as I understand, because of the huge gravitational sink existing which sucks all radiations in (except the gravitational one).
…A long time ago, in a galaxy far, far away…
Two black holes subdued to the gravitational pull and coalesced into a single entity. While coalescing, they violently rippled the space-time surface and on 14th September, 2015, these ripples reached planet Earth and were successfully recorded and deciphered.”
