So I guess this Einstein guy really was pretty smart huh? wink

OK Gravitational wave ok what now do we do?? I see it took them 6 months to confirm the wave but what does this mean in practical terms a new wave form generator or something??

I would imagine now that their existence is confirmed, the next step is building more sensitive detectors, and then working to connect what we detect with what we can observe via other channels.

And from there, trying to interpret other detected signals, to determine their likely sources/causes. Same as with electromagnetic signal bands.

It's basically a new way of observing our universe, which is a pretty substantial achievement.

Einstein borders on the mythical when you really think about it.

To measure and confirm this phenomenon, they had to be able to measure differences in light-length of 1/1000th the diameter of a proton! Apparently the miracle of this discovery isn't What Will Change, but What Has Been Confirmed. This, Higgs-Boson and other recent observations have told leading theorists that they are on the right path. Too cool. (I just wish I could understand a modicum).

When the other detectors come on line, subsequent
event detections may be localized via triangulation,
so the objects may be located visually with telescopes,
and we can see what sort of things happen when these
events occur. There is some reason to think that they
may correlate with gamma ray bursts.

GW150914 position is only very poorly constrained by
the time delay between the two detector:
"With only two detectors the source position is primarily
determined by the relative arrival time and localized to an
area of approximately 600  deg2 (90% credible region) "

600 deg is 20x30 deg of sky, a pretty big chunk - the
moon is 1/2 deg diameter.

The paper is publicly available to read here:
https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.116.061102

The "Fact Sheet" here just says "Likely Location: Southern Hemisphere"

They didn't waste any time getting a wiki page up:

https://en.wikipedia.org/wiki/Gravitational_wave_observation

Fun quote:

"Analysis of the signal along with the inferred redshift suggested that it was produced
by the merger of two black holes with masses of 36 +5/-4 times and 294 times the mass of
the Sun, resulting in a post-merger black hole of 624 solar masses. The missing 3.00.5
solar masses of energy was radiated away in the form of gravitational waves, in accordance
with massenergy equivalence. The peak radiated gravitational wave power of about 3.610^49
watts was over ten times more than the combined light power radiated by all the stars in the
observable universe,[2][12][n 1] or 0.1% of the Planck power."

So the output was equivalent to annihilating 1.5 solar masses with
an antimatter equivalent, except the energy all went to gravitational
waves rather than electromagnetic. Must have been interesting for
anything in the near vicinity (where near is a few light years)...

Artists conception of the merge. Pretty cool, slowed down but supposedly would happen in about 1/3 of second realtime.









Thank you, PV1.
