Merging the strong force with the gravitational force

In summary, there has been speculation about the possibility of merging gravity and the strong force mathematically. This is due to the compatibility between the two forces, as the gluon is the only vector boson capable of causing a force between similarly charged objects. It has been suggested that there may be a gluonic field that behaves similarly to virtual photons in an electromagnetic field, which could potentially explain the weak strength of gravity. However, there are constraints and complexities involved in this calculation, and it is uncertain if it is being actively considered or has been disproven. The Weinberg-Witten theorem has placed limitations on the idea of the graviton being "emergent" from another quantum field theory, but string theory offers a potential unification

has anyone tried to merge gravity and the strong force mathematically?

The two seem very compatible--the gloun is the only vector boson capable of causing a force to be applied between two similarly charged objects.

Isn't it likely that there is some kind of gluonic field, which behaves similarly to virtual photons in an electromagnetic field, which would basically be gravitation?

it would explain why gravity is so weak too, since the strong force is the most powerful force at 10^-15 meters, but then falls off exponentially. However it is still non zero, and the negative rate of change of the exponential decreases. But if you integrated the strength of the strong force with respect to distance across the mass of the system, then i could see the small components of the strong force adding up and resembling the gravitational pull of a system. it seems like a complicated calculation though.

Just curious if this is being considered at all or if it has been disproven.

The Weinberg-Witten theorem puts strong constraints on the graviton being "emergent" from another relativistic quantum field theory (but things like Sakharov's induced gravity are not ruled out by the Weinberg-Witten theorem). The graviton and something like QCD are unified by string theory which evades the Weinberg-Witten theorem.
 

What is the strong force and the gravitational force?

The strong force is one of the four fundamental forces of nature and is responsible for holding together the particles that make up the nucleus of an atom. It is the strongest force, but only acts over a very short distance. The gravitational force is the force that attracts all objects with mass towards each other. It is the weakest of the four fundamental forces but acts over a much longer distance.

Why do we need to merge the strong force with the gravitational force?

Currently, the strong force and the gravitational force are described by two separate theories - quantum chromodynamics and general relativity, respectively. These two theories cannot be reconciled, and merging them would provide a more complete understanding of the universe at both the smallest and largest scales.

What challenges are there in merging the strong force with the gravitational force?

The main challenge is that the two forces operate on vastly different scales and have very different behaviors. The strong force is a quantum force, while gravity is a classical force. Additionally, the mathematical equations that describe each force have different structures and are not easily compatible.

How far have scientists come in merging the strong force with the gravitational force?

While there have been attempts to merge the two forces, such as string theory and loop quantum gravity, there is currently no widely accepted theory that successfully combines the strong force and the gravitational force. Scientists continue to work on merging these two forces and finding a unified theory of the universe.

What implications would a successful merger of the strong force and the gravitational force have?

A successful merger of these two forces would not only provide a more complete understanding of the universe, but it could also potentially lead to breakthroughs in technology and advancements in fields such as astrophysics and particle physics. It could also help us answer fundamental questions about the nature of space and time.
