Gravitational waves

[Jitendra Hy-do-u-no-us?]

We are going to b able to understand much more of the universe thru the evidence of Gravitational Waves. For instance: Black Holes that were at one time unobservable except thru the energy flowing into them can now be detected thru the medium of gravitational waves coming from them.

A gravitational wave is a propagating wave of gravitational energy produced by accelerating masses, especially during catastrophic events, as the gravitational collapse of massive stars.

These black holes were also some 5 trillion light years away. Oh, and the collision happened 1.3 billion years ago. 

It's funny, happened so long ago, yet it's news to us. Just think if we could observe what is happening now, seems like we're getting way yesterdays news.

You have to wonder, what has God up his sleeve disseminating this info?

Hopefully he feels bad that he left us trapped in this movie theater... when there r all these horror shows being played.

We are finding out just how much the universe and everything in it effects our reality. This could be one thing he is showing us.

[Jitendra Hy-do-u-no-us?]

There is so much that effects our reality. It is for us to let it.. or realize it might just b someone elses reality. But there r things out there that have an effect on everyone. Gravitational waves seem to b one of them.

I wonder, I really do.

BTW, thanks for the chat, not many folks round these parts that like to talk spiritual-minded.

Sure SI

(i called SI last nite)

Hopefully u r able to b that lite hearted most of the time. It rubs off u know. I liked your story about your parents as entertainers perhaps it is y u understand one such as my self. U might share it with everyone. Wouldnt mind hearing it again.

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.”

The coalesced binary system lost about 3 solar masses after the coalescence. Such mass, transformed into gravitational radiative energy, has reached us and has been detected by Ligo.
As far as I collected, the waveform or signal only lasted a quarter of a second and the wave frequency is high (from 35 to 250 Hz)

Hello mccoy

Really appreciate your contributions and presence. i am not sure where u find 'unread posts' so i am not able to respond to what you have said. i always go to 'view the most recent posts' at the bottom of the forum (under stats) and found everything there that has recently happened.

Steve yes, I'll do as you do since my way has not proved to be always effective. On the top left-hand side you have 2 links: Show unread posts since last visit., Show new replies to your posts., but at times they do not actually indicate new posts.

O.K. now i see them. i'll have to check them out as well. i'll let u know what my experience is!

This is another very interesting image showing the timescale and the computed waveform of the black holes collision: decreasing distance, increasing velocity/mass, the large spike of collision/merger, the disappearance of the signal after the merge.

There are some very clear explanations of a phenomen which up to a few decades ago only some of the specialized physicists fully understood.

This is also a new kind of telescopy, we'll be able to observe violent phenomena as neutron star collisions, supernovae, gamma ray bursts and study the information conveyed by the gravitational waves.

The gravitational waves of extremely low frequency whose wavelenght can span a universe are also believed to be the original quantic fluctuations just before the inflation of the universe, right after the big bang, such quantic fluctuations were present in the primal seed and are allegedly the cause of the unlikely dishomogeneity of the universe.

Primordial gravitational waves: the seeds within the primal seed (the fingerprints of GOd???) - from the Quora poster "Huang China". This is a possibl efascinating application of GW detection, although I believe LIGo is not able to detect ultra low frequencies.

Till now our knowledge of the early universe is from the cosmic microwave background(CMB). However, the early universe is filled with plasma, which is opaque to electromagnetic radiation. So the CMB only tells us what happened 378 thousand years after the big bang. However, the gravitational waves can travel freely through the plasma, so it provides an insight into extremely early universe events such as inflation. Such gravitational wave is called primordial gravitational wave.
The BICEP II last year announced the discovery of the primordial gravitational waves, but it was soon   falsificated by the datas from the Planck. Now many teams, including BICEP III are competing for the discovery of primordial gravitational wave. If it is verified, it will greatly promote the development of cosmology and possibly the quantum gravity.
