Re: Gravitational Waves Detected By LIGO!

I thought the gravitational waves were generated as the black holes rotated around one another, not (merely) as a consequence of the collision. Also, what kinds of interactions transfer the energy/mass of the black holes themselves into gravitational waves? I wasn't aware that any energy was

Re: Gravitational Waves Detected By LIGO!

Thanks John, interesting. Does current theory make any predictions on how much energy (electro-magnetic and otherwise) actually is produced during ring-down, despite the inability to observe it due to the event horizon? On Fri, Feb 12, 2016 at 11:37 AM, John Clark wrote: >

Re: Gravitational Waves Detected By LIGO!

Yeah, I know, but I was wondering if because we are all about photons, earth-life, etc; I wondered if we will find interesting things that don't show up photometrically, visible light, ultraviolet, infrared, xrays, gamma rays. Like a magic gravity telescope that would see something out there in

Re: Gravitational Waves Detected By LIGO!

Two massive bodies orbit one another - the interaction is gravitational. As their positions change, the gravitational field due to their mass-energy must change. But it can't change instantaneously at distant points; the change propagates outward at the speed of light. This is a wave in the

Re: Gravitational Waves Detected By LIGO!

Sure, but John said the black holes lost 3 solar masses, which was converted into gravitational waves... how? Fusion and fission are easy examples of mass to energy conversion - so what's the specific interaction here according to theory? On Fri, Feb 12, 2016 at 10:49 PM, Brent Meeker

Re: Gravitational Waves Detected By LIGO!

If you were in one of the galaxies involved with the colliding black holes, would you be close enough to the gravitational waves to feel them on any kind of macroscopic level such as the one we inhabit? On Fri, Feb 12, 2016 at 4:12 PM, John Clark wrote: > > On Fri, Feb 12,

Re: Gravitational Waves Detected By LIGO!

I also wonder how long it will take to develop refined gravity detectors and what this would uncover? If it takes centuries, wake me up when its over. I know we have detected neutrinos for decades, and I don't think any fundamental changes in cosmology has occured? Its always the sizzle of the

Re: Gravitational Waves Detected By LIGO!

The interaction is gravitational. The first experimental evidence for gravitational waves was the correct derivation of the observed orbital decay of a double star due to energy radiated as gravitational waves. Brent On 2/12/2016 4:57 AM, Terren Suydam wrote: I thought the gravitational waves
