Who says physics is boring.

Well, not really gravity. It's resonance harmonics. Still really cool though!

Well, they did say that gravity was influencing the wave interactions. They've even associating gravity waves with the formation of clear air turbulence.

lol. Tc, gravity effect just about everything on this planet that has mass.

Only just about anything?
Can you give me some examples of the exceptions?

Yeah, but to think that gravity has
waves in it boggles the mind. I'm always thinking, incorrectly apparently, that gravity is a constant acting force, not a fluid one with variations. I was never good at physics I guess.

I think you're confusing two things:
1.
Gravity waves, produced by a restoring gravitational force vs. a displacement (e.g. the picture above, or ocean waves).
2.
Gravitational waves, theorized relativistic ripples in spacetime (this has nothing to do with the star-patterned waves in your original post).

English language, why you so bad for science?

That's what I was getting confused about. I guess I had some concept of rippling gravity waves going through the substance that caused those wave formations. Now it makes more sense.

Oooh, more gravity wave pictures, in Venus' atmosphere.

Neat!
Here's a report about
solar wind-produced water.
A bit heady, but interesting.

They say the Tsunami in Japan had the same effect on our atmosphere. I think the only similarity would be on a quantum scale. Just a moving of particles.

“There is no escape from a black hole in classical theory,” Hawking told Nature. Quantum theory, however, “enables energy and information to escape from a black hole.” A full explanation of the process, the physicist admits, would require a theory that successfully merges gravity with the other fundamental forces of nature. But that's a goal that has eluded physicists for nearly a century. “The correct treatment,” Hawking says, “remains a mystery.”
I like this because I think so too.
