Great discovery!

EDIT: link to article: https://dcc.ligo.org/public/0122/P150914/014/LIGO-P150914%3ADetection_of_GW150914.pdf

A confirmation that Einstein had it right after all. This coupled with the recent announcement concerning the 'changeable state' of neutrons could be the first real clues as to the nature of Dark Matter and Dark Energy.

YES truly a great discovery!

I had been starting to wonder if I would live long enough to see this day and sure enough, I have!

To live long enough to see yet another validation of Einstein just makes my day!

The experimental waveforms coincided almost exactly with the numerical simulations made using Einstein's field equations. This means that the equations are still valid at a great distance and not only locally. This is a very important part of this discovery.

Yes it is. Perhaps that means that the laws of physics were fixed at T=0. Not necessarily the constants we observe today, but the laws.

Interesting point

And we now have the beginning of a whole new wavelength 'window' through which to view the Universe.

+100! Just printed out the article, have some lecture for tonight then. Thanx Raistmer. I hope this will shed a new light on the existence of the graviton as well.

A really remarkable triumph of persistence, ingenuity and precision! It'll be interesting to see what they can do, eventually, with a network of these gravitational wave detectors, around the world, and eventually in space. With two near-simultaneous detections about 2000 miles apart, they could only say that the merging black holes were in the southern celestial hemisphere.

Since mass-less gravitons, at extreme energy levels also propagate at light speed, this does not leave much room for the possibility of FTL travel.

Gravitational wave detectors in space is already underway.
LISA Pathfinder will test technology for gravitational-wave observatories in space.

Sadly I haven't kept up with this... Maybe a pointer or suggestion on we're to find out more?

Probably he meant neutrinos, not neutrons, which do not change state.

Not really, AFAIK this is a proof of concept test, Lisa Pathfinder is not looking for GW.

If true that there were a verified collision of two black holes that were actually detected then it would be more remarkable if they could declare there is no such thing as gravitational waves. I say this because we are 100% sure that mass warps space.

I always thought that any LIGO -type apparatus on Earth would not have the isolation nor the sensitivity to detect a true gravitational wave --especially from a collision a billion light years away. I would more easily believe that they all detected the Taiwan earthquake or a passing semi truck.

I think also that when we get the interferometers out in space that we will detect such waves on a fairly regular basis.

What has (always) had me scratching my head is:
How could they say 'with certainty' that the waves are from this one (or any) specific event?

Tullio

Absolutely correct Tullio, I said neutrons but meant neutrinos. They seem to change 'flavor' during their life and there is theory they are a physical manifestation of Dark Energy/Matter. Here's a .pdf on the subject by the recent Nobel Physics winners.......

I knew about the neutrinos, and vaguely knew that 'solitary' neutrons could decay into protons (+ extra stuff); I just thought/was hoping that there was something new that I hadn't heard about.

Concept test?

"This is tremendous news for everyone studying gravity and general relativity, and we send our warmest congratulations to colleagues in the LIGO collaboration for their outstanding result," says Paul McNamara, LISA Pathfinder project scientist at ESA.

LISA Pathfinder is ESA's technology demonstration mission for possible future missions to observe gravitational waves from space. Launched on 3 December 2015, the spacecraft reached its operational orbit in January and is undergoing final checks before starting its science mission on 1 March.

"With LISA Pathfinder, we will be testing the underlying technology to observe gravitational waves from space, and it is even more encouraging to know that these long-mysterious fluctuations have now been directly detected," adds Paul.
