Do you want to hear my own theory of gravity?

[erik]

I am a mere student in mathematics and physics and by no mean a specialist, however I am fascinated by the quantum gravity problem, so I've read a lot of documentation about it.

I have learned the basic concepts of general relativity and quantum field theory and spent a lot of time trying to understand the intricate relationship between energy, mass, gravity and spacetime.

Recently I have come up with a very simple idea that could explain what is the true nature of gravity and spacetime. What led me to this idea is one of the characteristics of the higgs field, its homogeneity.

However, being a humble newbie, I realize my idea is almost certainly wrong. On the other hand, quantum gravity theories have been stuck for a while, so maybe all ideas are worth listening ?

Please let me know if you want to hear my idea and if you do, I will post it below. Thank you.

Being a humble newbie, you should have posted this in the correct section...speculation.

Sure.  There several members who have a good understanding of general relativity and quantum mechanics so you could get useful feedback on your idea.

Thank you (and sorry for posting in the wrong section).

Before I get started I need to specify that my first language is French so please bear with me if my terminology is inaccurate.

So as I stated above, my idea came up after thinking about the homogeneity of the Higgs field.

I realized the Higgs field appears to behave like a gas that has reached its maximum entropy. Since mass is defined as the interaction between massive particles and the Higgs field, it is reasonable to think massive particles disturb the homogeneity of the Higgs field, and create regions of lower density. If the Higgs field obeys the second law of thermodynamics then it would immediately react by trying to regain its maximum entropy, and much like a gas, it would generate a pressure on massive particles and affect their trajectories. Through the second law of thermodynamics, we could rebuild the mass/geometry mutual influence of the general relativity.

Regions of high matter density like planets or stars would have a low Higgs density, and gravity would be nothing more the Higgs field pressure to regain its maximum entropy.

If this theory is correct, spacetime would be nothing more than the Higgs field itself and the hypothetical graviton would be nothing more than the Higgs boson.

One way to test this theory would be to build a particle accelerator in outer space and see if Higgs bosons are more common in regions of low matter density than they are on Earth.

That's it. This theory is very simple as you can see and I would appreciate your feedback. Thank you for reading.

The hypothetical graviton cannot be the Higgs boson because (a) the former should be massless while the latter is massive, (b) the former should be spin-2 particle while the latter is spin-0.

I think you are referring to the prediction of the string theory, but I completely dismissed the string theory in my post above.

My idea is based on the standard model (quantum field theory) which does not have a graviton.

Which "hypothetical graviton" did you refer to?

Any attempt to build a quantum gravity model requires a boson that carries gravity. But the properties of that boson depends on the model. In my (very modest and probably wrong) "model" I assume that gravity doesn't have a specific boson because it is carried by the higgs boson of the standard model.

Well, then this boson has to be massless in order to propagate with the speed of light as required by GR. And it was Richard Feynman I think that showed that such boson has to be spin-2 particle, based on GR again.

That’s not true. Instead of introducing a quantised field on smooth spacetime, you can quantise spacetime itself, giving you a set of models that do not require a graviton. One example of this is Loop Quantum Gravity.

Higgs bosons do not have the required properties to be carriers of gravity, as Grenady correctly pointed out.

This is a good point actually, since gravitational waves have recently been confirmed to  travel at the speed of light with extremely high accuracy, I have to add a graviton field to my model.

When I think about it, it makes even more sense now since the graviton would play exactly the same role as photons in the entropy of a gas.

Moreover spacetime could emerge from the interaction between higgs and graviton fields, just like the electromagnetic field emerges from the interaction between eletrons and photons respective fields. The higgs field would generate time and the graviton field would generate space.

Sadly I can not edit my post above. Why? Can a mod edit the post above for me or do I have to start a new topic?

No problems. The point I make is that we have had many come to this and other science forums, with new untested, sometimes unscientific ideas, and post them in the sciences, to obtain some air of respectibility.
