One initial interest i find is that what is so extremely far away can have an effect on something here. Makes ya think what more effect a planet so much closer would have.

If gravitational waves are distortions in time and space that are caused by the size of physical objects.....Correct me if im wrong. This being the case wouldnt those distortions in time and space effect us if we r drawn into the influence of such objects. It appears we r. because that is how we have found orbotting objects in our small solar --- through the relationships of such objects and their pull on each other.

Falling, up and down are relative to an object with mass. In our case the earth. An illustration they like to use is a trampoline. A heavier person than you will create a depression in the trampoline fabric which will pull you toward that person to some degree. Similarly, objects in space-time that have more mass pull in all the objects around it because it 'curves' space-time around itself. Except space-time is not a one-dimensional flat piece of fabric. Does that make sense?

My understanding of this stuff is very basic, if I understand it at all. I have been browsing around YouTube for explanations. They are all hard.  :D

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

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

LOL

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

I wonder, I really do.

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

…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.”

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).

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.

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.

A crude formula for the measured strain from the gravitational wave due to a binary star system is given by:
h∼2G2M1M2c4aD,h∼2G2M1M2c4aD,
where G∼6.674×10−11 m3/kg/s2G∼6.674×10−11 m3/kg/s2 is Newton's constant of gravity, M1M1 and M2M2 are the two masses, c=3×108 m/sc=3×108 m/s is the speed of light, aa is the separation between the stars and DD is the distance from the detector.
If you substitute M1=M2=30M⊙M1=M2=30M⊙, a=100 kma=100 km and D=421 MpcD=421 Mpc (after appropriate conversion of units, of course), for a separation of a=100 kma=100 km you get h=3×10−21h=3×10−21, so crude it might be, but the formula is not useless.
And it tells you that the strain is inversely proportional to distance. Which means that  if you were, say, 1 astronomical unit from the source, the strain would have been h∼3×10−7h∼3×10−7. This would have been easily detectable with a desktop experiment. (Very easily, as a matter of fact, as this strain exceed the sensitivity of the Michelson-Morley experiment from 1887 by ten orders of magnitude. Of course Michelson-Morley was not designed for this frequency range, but even so, it would have seen it for sure.)
Not only that, but since the gravitational wave emitted by GW150914 was in the audio frequency range, I suspect that humans would have heard it as the strain, acting as a momentary passing tidal effect, would have stressed their eardrums. That of course assumes that there were either no non-gravitational effects (e.g., deadly radiation from a disturbed accretion disk surrounding the coalescing binary) or the humans were well protected, so they could enjoy the "chirp" instead of having to flee for their lives...

There are four main sources of gravitational waves caused by different kinds of motion and changing distributions of mass - continuous, inspiral, burst, and stochastic.

nspiral gravitational waves are generated during the end-of-life stage of binary systems where the two objects merge into one.  These systems are usually two neutron stars, two black holes, or a neutron star and a black hole whose orbits have degraded to the point that the two masses are about to coalesce.  As the two masses rotate around each other, their orbital distances decrease and their speeds increase, much like a spinning figure skater who draws his or her arms in close to their body.  This causes the frequency of the gravitational waves to increase until the moment of coalescence.  - See more at: http://www.ligo.org/science/GW-Inspiral.php#sthash.epf2kvAH.dpuf

Now, the last step. Pls Steve and others let me know if the plots and explanations are clear now. The recently detected waves are plotted in the following official graph

We can clearly see the ripples becoming gradually wider and more frequent, startign from time 0.3 seconds to time 0.42, when they are the highest and the closest.

At time 0.3 the black holes started to approach to each other, increasing significantly in velocity and mass. At 0.4 second the black holes are revolving around each other very, very closely, with velocity at about half lightspeed. The last spikes testify the moments just before the collision, after which there are no more gravitational waves (seconds 0.43 to 0.45) since there are no more two black holes, just a single, larger one which is spinning in a close to circular simmetry, hence radiating no gravitational waves.

The dramatic collision, where two bodies which total mass amounting at about 30 times our sun, has ended. The GWs detected are exceedingly and incredibly tenuos. I still can hardly believe the devices could detect them.

mccoy wouldnt it b fascinating to have graphs like this to measure spaces between breaths and breaths per minute while meditating?
