Re: Gravitational Waves Detected By LIGO!

Energy, John Mikes, is just a measure of change in a physical system with time. Or change in arrangements of spacetime in the time direction. And what is mass? It's just changes in spacetime in the space direction(s). And it turns out each can be rotated to become the other. What is spacetime?

Re: Gravitational Waves Detected By LIGO!

Great, but what is the specific way in which mass is converted into the energy required to produce gravitational waves? When planetary orbits decay, kinetic energy is lost... No mass is converted. On Feb 13, 2016 1:20 PM, "John Clark" wrote: > On Sat, Feb 13, 2016 at 1:00

Re: Gravitational Waves Detected By LIGO!

Ahhh, makes sense, you know, in the absurd way that anything in relativity or QM makes sense. One more question. A mass is hurtling through space (not in orbit, to keep things simple). In the mass's frame of reference it has zero kinetic energy. It is at rest. From the perspective of a nearby

Re: Gravitational Waves Detected By LIGO!

Depends on what you mean by "its mass". As used in particle physics, that phrase always refers to the particles rest-mass, which is an invariant (the same in any coordinate frame). But if you think of "its mass" as referring to the strength of the body's gravitational field, then yes its

Re: Gravitational Waves Detected By LIGO!

In relativity mass and energy are interchangeable. For example, most of the mass of a proton is in the kinetic energy of the quarks. When a planetary orbit decays (by radiating gravity waves) kinetic energy is lost and this shows up as less gravitational mass for the sun/planet system. So

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!

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

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,

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
