In the context of modern physics, the role of gravitons is related to the theory of quantum gravity, which seeks to reconcile the principles of quantum mechanics with the theory of general relativity. However, the concept of gravitons and the idea of gravity as an illusion created by time dilation gradient are somewhat distinct and arise from different theoretical frameworks. Let me explain further:
Gravitons: Gravitons are hypothetical particles that are postulated within certain quantum theories of gravity, such as string theory or loop quantum gravity. These theories attempt to describe gravity in a quantum mechanical framework. According to these theories, gravitons would be the elementary particles that mediate the force of gravity, much like photons mediate the electromagnetic force. However, it is important to note that the existence and properties of gravitons are still speculative, and their direct experimental confirmation has not been achieved.
Gravity as an illusion created by time dilation gradient: This idea seems to be rooted in the notion that gravity can be explained purely in terms of the effects of curved spacetime, as described by general relativity. According to general relativity, the presence of mass or energy curves the fabric of spacetime, and objects move along the geodesics (paths) dictated by this curvature. The curvature of spacetime can lead to phenomena such as time dilation and the bending of light.
In this perspective, the concept of gravity as an illusion arises from the interpretation that the observed effects of gravity, such as the motion of objects or the acceleration experienced, can be explained solely by the curvature of spacetime rather than invoking a fundamental force mediated by particles like gravitons. Instead of attributing the effects to a force, they are seen as emerging from the geometry of spacetime itself.
It's worth noting that the concept of gravity as an illusion created by time dilation gradient is not a widely accepted or mainstream view in physics. While time dilation is indeed a consequence of the curvature of spacetime, it is generally considered an intrinsic property rather than a result of an illusion. The vast body of experimental evidence supports the existence of gravity as a fundamental force and its description by the theory of general relativity. The precise nature of gravity at quantum scales, including the role of gravitons, remains an active area of research and a topic of ongoing theoretical investigations.
