Gravity waves analysis opens 'completely new sense'

It's my opinion that gravity waves are the real cause of my recent weight gain.

Or, keep you from walking a straight line in a roadside sobriety test ;-)

I'll turn seventy on election day, I have become very knowledgible of gravytie stains, not to mention my poor shirt when not wearing a tie.

How do gravity waves escape black holes?

"Scientists are frustrated as they seek to recalibrate their instruments each time Rosie O' take an intercontinental air trip..."

It's when she jumps up and down that their instruments go crazy...

Barf.

....or you could visualize Jerrold Nadler playing hopscotch. Barf.

When he does, they'll be a gravity wave tsunami that will hit Andromeda galaxy in a few hundred thousand years.

Please, no BUMPING in the vicinity of the gravity wave detector.

I'm not sure how useful it would be.

In all likelyhood the events would be hundreds of lightyears away making the propagation sphere a planer phenomena when it strikes Earth assuming the "wave" has any discernable energy to be measured.

At near-lightspeed velocities and a relatively small window to observe the arc, the "difference" would be measurable in nanoseconds or less - under the assumption that Earth and/or its magnetic field doesn't distort the wave.

Probably just a scientist trying to drum up funding for his research. Not that I disagree with it, it could prove very useful someday.

[RightWhale]

it could prove very useful someday.

Of course. At this time nobody would know. So it is science, looking for new data. If they were developing something specific that used gravity waves to do something useful, that would be engineering. Science is finding new things all the time, not all of it has immediate application, but we keep looking and will keep looking until nothing new is found. Then we're done. Like physics was thought to be done 100 years ago. Except it wasn't done at all.

Is there a black hole in the middle of Uranus?

"Think of it: Gravity waves come to us from the edge of the universe, from the beginning of time, unchanged," he said. "They carry completely different information than electromagnetic waves. Perhaps the most exciting thing about them is that we may well not know what it is we're going to observe. We think black holes, for sure. But who knows what else we might find?"

If gravity propagates at the speed of light, we wouldn't be able to detect gravity waves "from the beginning of time". If gravity propagates considerably faster than the speed of light, we certainly couldn't detect anything from the beginning of time, though in either case one could detect something from the edge of the universe, providing there actually is an edge. If there were an edge, though, it wouldn't be the same thing as the beginning of time.

Get this: Everything you see and everything you are is the gravity wave from the event at the beginning of the universe crossing in constructive and destructive interference with itself from all directions RIGHT HERE! Unless you wish to consider the 4-plex manifold. In that case you can add RIGHT NOW! Like selling used cars. :)

Assuming there was a beginning, a proposition (in the Big Bang sense) that is less than certain.

[Southack]

Gravity is the Energy of a Mass, therefore

G=EM

Since we already know that E=MC^2, we can solve for G, giving us G=C^2.

So Gravity is the speed of light squared (just try to ignore the dimensional consistency/inconsistency aspects of that equation).

[boris]

"How do gravity waves escape black holes?"

I defer to Physicist.

My meager understanding is that they don't. The gravitational field around a black hole is a "fossilized" remnant of the original star.

This begs the question: as a black hole sucks in more mass, it gets bigger and thus should have "more" gravity than prior to injestion of more mass. I suspect the answer is that the gravitation (gravitons, gravity waves) originate at the event horizon, not the geometric center of the hole.

Other than that, all I can say is that I have wondered about this question myself.

Obviously the gravity wave interference pattern is of a slowly evolving standing wave. That is, either you are not at the center or the Big Bang is not a singularity at some distant time and space, but continuous throughout all time and space. This is in no way comparable to the Hoyle Steady State model. Probably we can use some variant of the least squares method, possibly Chebyshev polynomials or Fourier series to attempt to model. We'll need some CPU time; perhaps a Federal grant. Or scribble some incomprehensible tensor equation and take the rest of the day off.

[BLASTER 14]

To those of you who are really interested in the subject(not those of you who made the smartass remarks), I recommend the following book: "The Elegant Universe: Superstrings, Hidden Dimensions, the Quest for the Ultimate Theory" by Brian Greene, W.W. Norton & Company, 500 Fifth Avenue, New York, NY, 10110.

It's heavy going, about 450 pages, but really interesting.

Cheers and happy reading.

G=EM

What is the indicial order of the equation? We'll need at least three noncoplanar potential vectors.
