Force carrier particles i.e. gravitons, photons

[FeDeX_LaTeX]

Hello;

How do force carrier particles work? For example, if I drop an object, the force of gravity is carried by gravitons. Does this mean that there is a long stream of gravitons underneath/all around the object? Because the wave would need to be carried through the medium of gravitons. Is this true?

Thanks.

Well, this is all hypothetical, so it may not be true. I'm guessing there isn't much evidence for force carrier particles?

They're a mathematical convenience.

The Hamiltonian operator of the force is an infinite sum of products of a finite number of creation and annihilation operators of particles.

For the electromagnetic force between two electrons, for example, or between an electron and a photon, those operators are of electrons and photons.

But that doesn't mean that any electron or photon is actually annihilated or created.

The photon being a "carrier" or "mediator" for the electromagnetic force only means that its operators appear in the Hamiltonian, not that they themselves actually appear in the interaction.

I'm confused... they're there, but also not there?

I have never heard of the Hamiltonian operator, I will google it.

I can provide some insight into the concept of force carrier particles. Force carrier particles are subatomic particles that mediate the fundamental forces of nature, such as gravity and electromagnetism. They are responsible for transmitting the force between two interacting particles.

In the case of gravitons, they are believed to be the force carrier particles for the gravitational force. However, it is important to note that the concept of gravitons is still a theoretical concept and has not been directly observed or proven. It is a part of the theory of quantum gravity, which aims to unify the theories of general relativity and quantum mechanics.

As for your question about whether there is a long stream of gravitons underneath or around an object, it is not entirely accurate. Gravitons, if they exist, are not particles that flow in a continuous stream like water. Instead, they are exchanged between particles during interactions, much like the exchange of photons in the electromagnetic force. This exchange of gravitons is what carries the force of gravity between objects.

Furthermore, the concept of a medium through which gravitons travel is not applicable in the same way it is for other forces like sound or light. Gravitons, if they exist, would travel through the fabric of space-time, which is not a physical medium but rather a mathematical construct.

In summary, the idea of force carrier particles is a key concept in understanding the fundamental forces of nature. While the concept of gravitons is still a theoretical concept, it may help us better understand the nature of gravity and its interactions with matter.
