The graviton is a hypothetical elementary particle that is currently only a concept in certain theories of quantum gravity. It is proposed to be the mediator of the gravitational force, similar to how photons mediate the electromagnetic force. However, it's important to note that the existence of gravitons and their properties are still purely theoretical at this point, and they have not been observed or discovered yet.
If gravitons were to be discovered and their properties confirmed, it could potentially lead to a deeper understanding of gravity at the quantum level. However, it does not necessarily imply that gravity could be directly manipulated without mass or velocity.
Gravity is a fundamental force that arises from the presence of mass and energy in the universe. According to our current understanding, the distribution and movement of mass and energy create gravitational fields, which in turn influence the motion of other objects. The discovery of gravitons would provide insights into the quantum nature of gravity, but it would not necessarily mean that gravity can be manipulated independently of mass or energy.
It's important to remember that the hypothetical discovery of gravitons and any subsequent understanding of their properties would require extensive research, experimentation, and theoretical development. Speculating on the potential applications or implications of such a discovery is challenging until it becomes a reality and a more comprehensive understanding of its properties is established.
