How many of you believe gravity cannot be quantized?

Question

I know they've been working on this for a couple of decades. It seems it would hold the key to some of the deepest secrets of the universe. It's related to some of the most fundamental cosmic questions. I know they've been searching for gravity waves and the particle which would be the basis for the gravitational interaction. It appears to be a worthy work, but at this point, are there many who believe that gravity is not like the other fields? It doesn't operate as the result of a particle or wave. It's a fundamental effect of relativity. And as far as unifying all the "forces," with gravity, have they considered the possibility that it's an apples and oranges proposition? Are there many in the scientific community who are, (and have been), skeptical of this whole line of investigation and believe this kind of research is going down a blind alley?

Answer 1

I believe there is no quantum of gravity.

I have my own model, and I believe gravity is an interaction between mass and dark energy. Dark energy propagates at least 20 billion times faster than light. It exchanges momentum with each fundamental particle zillions of times per second, and the amount of each exchange of momentum depends on the polarity, wave length and phase angle. Therefore, it is not quantized.

Answer 2

I think gravity is similar to the electromagnetic force except for not having polarity, so I don't see why they can't be unified.

Answer 3

You could very well be right but we're still left with the theory that at the instant of the Big Bang the four fundamental forces - including gravity - were unified. I'm not enough of a physicist to provide details about why this initial unification is so widely accepted and indeed it could be totally wrong. However, If we assume that the theory is correct then we'd be left with the four individual forces of today, three of which have verified messenger particles associated with them (weak nuclear force propagated by W+, W- and Z-zero particles, electromagnetism propagated by the photon, and the strong nuclear force propagated by gluons) It seems only logical and reasonable that gravity too should have a messenger particle (graviton), and if so then it too can be quantized.

To me it also seems significant that spacetime, which can also be quantized, responds to what we call gravity. Can some quantifiable cosmic feature be influenced by an unquantifiable phenomenon? I don't know.

Answer 5

I lean toward it being quantitized; that is, at one point a gravitational field would not have the ability to pull a particle toward it.  I don't really have a problem with it doing that.

As it is, I am elated that the case for time and space being discreet has gained so much ground.  It helps me to disprove Hawking radiation... but it isn't the only reason.

I'm just a boy from the sticks and it would make my day to understand how a gravitational field can affect the flow of time for the local area.  I am still a little skeptical that space-time curves as a response to mass.

Call me crazy but sometimes things are not quite as they as taught by the best minds... like Bekenstein saying that a black hole has lots of entropy in the form of information that it could theoretically store.  

Okay, I'm just babbling now.

So, back to your question... gravity is so very interesting and I believe that this business of how gravity can affect the flow of time, in one moment be the weakest force, and then in a singularity be the most powerful force, how perhaps its speed of propogation may allow it to effectively the universe in a single unit of Planck time (given that it was not a quantum field) and exceed the Universal Speed Limit of c without violation because it is not matter,...

I'm sorry; I'm getting all side-tracked there again.  What I want to say is that our attempts to define and understand gravity as it exists today are in search of conditions and laws of a universe that is almost to the end of being whole; whole meaning as it was at the moment of the Big Bang, when things were proper and the four forces were one.  Everything after that has just been the breaking down of the Prime Conditions.  We ask why the four forces are so unalike in their present condition; why symmetry is broken; etc.  And that is the answer.  As the universe now stands, it's a near dead relic of what it was.  The temperature of the universe is less than three Kelvin.  It used to be in the billions and much more.

Why do we think that our universe as we pesky little human viruses see it is of any importance?

Okay, I need to go to bed and stop ranting like the lunatic that I am.  You deserved a much more coherent and succinct answer.  My apologies.

--------------------------

Now that I have gained my sanity, I came back to delete this answer of mine... but I see that I have received three thumbs up and no thumbs down.  So I guess that it wasn't too bad after all.  I am humbled.

Answer 6

Well.....  If anybody ever figures out 'Grand Unification' we may be a bit closer to understanding how to unify GR and QM.  But I think that's going to be quite a few years away.

Answer 7

I doubt it. There is evidence that gravity travels at the speed of light. If so, there must be a transfer particle (graviton), and if there is a particle it is quantized.

Answer 8

I believe that gravity is nothing but a measure of space-time (it is not a force). If you look at space in one direction for example, distance changes with distance and gravity represents the non linear space-time. As you approach matter (which I believe to be made of photons and photons are nothing but a knot in space-time fabric), space becomes more stretched.

I think space and time move in the direction of matter. for this reason:

1) Gravity is not a force

2) F=mA...if F=0 then A=0

3) An object in motion remains in motion unless acted upon by a force.

4) Space-time moves toward the earth.

5) hold an object in your fingers and it is accelerated against space-time moving toward earth.

6) release the object and it continues moving with space-time

7) it appears to accelerate relative to us, but it is just traveling at a constant velocity in accelerating spacetime.

But I am ready to be reasoned with.

I am not sure about the quantizing though. It is the only way I can see time "stopping" and space "stretching to infinity" at an event horizon. I think as I approach the event horizon, the horizon moves away from me due to my space-time being closer to the space-time of the event horizon as observed by a distant observer.

Answer 9

OK~~~~

Here's where I get to show off my lack of schooling in

Physics.  

Speaking as a total layperson with a keen interest

in science, it just seems to me that gravity would have

to be part of the "Perfect Model" that unifies all the laws

of physics.  And Gravity certainly seems to be part of

physics, and the laws of nature.  How can you omit it?
