Gravity isn't just a good idea; it's the law.

Google “gravity push vs pull”. There is a strong case that gravity doesn’t actually pull. Rather, it is actually a “push” force.

And the fact that the argument can even be made shows how little we know about it.

This cat failed beating gravity though...

It’s quite possible that gravity is quite literally the mind of God holding everything together until the day of judgement, when he just mentally says, time for a fresh start.

Note this:

"The ground-based LIGO experiment might someday detect a gravitational wave, but there’s been no luck so far. The Space-based LISA experiment should detect gravitational waves with more precision. The first version will launch in 2015, but the real experiment probably won’t be operational until 2030."

Robert Forward (SF writer, scientist, all around smart guy) was searching for Gravity Waves at UCLA in the late 50's. There may have been earlier experiments. But so far we have zero evidence that they exist. Very odd. Very strange.

Gravity is basically the force of weak implosion.

I just love biscuits and gravity.

He ain’t heavy it’s gravity ping.

My theory ... osmosis ... if I'm right, you heard it here on FR first. Now ... if only I could identify the semipermeable "membrane"-like component of matter and the "solute"-like component that permeates our universe. Then the existence of another universe, having a lesser concentration of the "solute", could be inferred. And, perhaps, not all matter contains the "membrane". It may simply be friction of the "solute" passing through us toward the "membrane" at the Earth's core that holds our feet to the soil. Perhaps only the celestial bodies have this "membrane" at their cores and have collected the debris the "solute" dragged with it to build mass. Mass may be the product of osmosis-gravity ... not the cause.

One of the amazing things about gravity is how weak it is.

At this moment, the mass of the entire Earth is pulling down on me, yet I can temporarily move my entire mass away from it by exerting less than 1 calorie of energy.

Another is that because of gravity, the universe and our reality are nothing like what they appear. For example, the Earth does not have a simple elliptical orbit around the Sun. If you could actually look at it, the Earth traces a wobbly orbit around the Sun. Why? Because the Earth is locked with our moon, which is relatively large. The Earth and moon actually orbit each other, with the center of mass being what orbits the Sun.

There is no gravity, the universe just sucks.

[Conservative4Ever]

Get down with gravity.

[Starstruck]

If gravity eventually wins out and all matter is pulled back together, will that point be the same as the point in which it all started?
