Do we have any theories to unify quantum gravity to gravity?
What is the opinion on this?
What about gravity to the other 3 forces?

AmiBlackwelder said:So quantum gravity exists because natural gravity as most know it exists?
So, if gravity disappeared quantum gravity would too?
AmiBlackwelder said:LOL,
I don't think it is any time soon, LOL
I'm just wondering theoretically what this all means.
So, when we hear 'quantum gravity' what is meant is the standard model plus gravity.
But, I'm confused, because how do we know that the gravity that pushes on the big stuff is the same gravity working on the small stuff?
And does it push that too?
AmiBlackwelder said:Ok, so gravity then works on the big and small.
But the other three forces seem to work on only the small, that seems weird. And gravity also seems to affect light and be a property of space itself? curvature?
the other three forces are not like this?

The concept of unifying gravity is a theory in physics that aims to merge the two fundamental forces of nature - gravity and electromagnetism - into a single unified theory. It suggests that both forces are actually different manifestations of the same underlying force.
Exploring the possibilities of unifying gravity is important because it could potentially lead to a better understanding of the fundamental laws of the universe. It could also help bridge the gap between general relativity and quantum mechanics, two theories that have been difficult to reconcile.
Currently, unifying gravity is still a theoretical concept and does not have any direct impact on our everyday lives. However, if a unified theory is discovered, it could potentially lead to technological advancements and improve our understanding of the universe.
One of the main challenges in unifying gravity is the discrepancy between general relativity and quantum mechanics. These two theories have different mathematical frameworks and it has been a struggle to find a unified theory that can explain both gravity and the behavior of subatomic particles.
Yes, there are several theories and ongoing research on unifying gravity, such as string theory, loop quantum gravity, and supersymmetry. However, none of these theories have been proven yet and the search for a unified theory is still ongoing.
