It goes with this ENTIRE PARAGRPAH:
One of the most exciting ideas in modern physics is that gravity is not a traditional force, like electromagnetic or nuclear forces. Instead, it is an emergent phenomenon that merely looks like a traditional force.

I think it could be a little of both. Why couldn't the quantum, which is eveywhere and in everything, have enough mass, if evenly distributed, to hold things down? It would be sort of like living on a planet surrounded by undectable jello - an energy "aura".
I understand what Erik Verlinde is trying to say. From a quantum point of view, it makes sence. From a Neutonian point of view, it can't be put on film. (I can also see why these two fine fellows dissagree.)

Gravitas, on the other hand...

remember the faster you go time slows down When in relative motion near the speed of light, two observers each think that the other observer's clock runs slow. Neither observer believes his own clock to be running slower.

(remember the faster you go time slows down) that's an implication of relativity, as opposed to a fact, correct?
To: FredZarguna
I hope that when everyone has satisfied themselves how it works, this universe with its gravity and its hundreds of kinds of curious particles, they give a little thought to why it should be there at all and what it means. God may be a pointillist painter, but it makes no sense to ignore the entire picture.

I have no idea what they are talking about but I did used to wonder how people on Star Trek always had plenty of gravity.
Of course it was probably no problem for Scotty.

The idea that gravity comes about due to fundamental entropy arguments only created quite a stir on Slashdot when it first came out a year or so ago. Unlike the armwaving of cold fusion, this guy’s paper is on the net, and you can follow along provided you have enough math/physics to understand it.

“The quantum”? Is there such a thing?

I wrote my thesis on this...1985....no big deal...I'll bet that was a weighty tome.

Maybe the floor was painted with dilithium paint at well under warp concentrations. The Enterprise never seemed to be plagued with outages to its gravity system.

Gravity is certainly no friend of my emergent phenomenon. Care to explain further? Or is the short version all you got?
To: HiTech RedNeck
Unification is a goal of Physics, obviously. But there aren’t that many (hundreds) of fundamental particles.

When in relative motion near the speed of light, two observers each think that the other observer's clock runs slow. Neither observer believes his own clock to be running slower.Which explains the holographic universe theory. Nothing is real until it is observed. Both parties saw their own reality. What they do with their own sense of reality determines the reality of all the others who come in contact with them. To each, their reality is real, and the other is in error.
The more people who believe one person or the other, the more the illusion becomes the reality to the masses. When they believe both, then time does slow down at the speed of light. Both pilots experienced the same thing, therefore, human conscience says time can be manipulated. It is now a human reality, because it is believed.
To: Williams
Maybe this is supposed to mean the existence of everything, at its smallest, in quantums? Like a wall or block made of woven beads that can’t individually be split?
I don’t grok stuff at this level very well, and I salute the scientists who have the minds suited to it.

What he is saying is not true.
However, an implication of relativity is a fact. The Special Theory of relativity is about as strongly enforced a law of Physics as any we have.
