Rainbow gravity (or “gravity rainbow” [1] ) is a theory in which different wavelengths of light experience different gravitational levels and are separated just like a prism splits white light into a rainbow. [2] This phenomenon will be invisible to areas of relatively low gravity, such as planet Earth, but will play a large role for areas of very large gravity, such as a black hole . [3] Thus, this statement refutes that the Universe has a beginning or that there was a Big Bang, because the Big Bang theory requires that all wavelengths of light be equally gravitationally affected. [4] This theory was first proposed in 2003 by physicists Lee Smolin and Juan Mageiu , and claimed that it bridges the gap between general relativity and quantum mechanics. [4] Scientists are currently trying to detect rainbow gravity using the Large Hadron Collider . [five]
Historical Background
The origin of the rainbow theory of gravity is largely a product of the mismatch between the general theory of relativity and quantum mechanics . In particular, “locality” or the concept of cause and effect, which defines the principles of the general theory of relativity, is mathematically incompatible with quantum mechanics. [6] This problem is related to incompatible functions between two fields; in particular, fundamentally different mathematical approaches are applied in the fields when describing the concept of curvature in four-dimensional pseudo-Euclidean space-time. [6] Historically, this mathematical split begins with a mismatch between the theories of relativity of Einstein , who saw physics through the prism of causality, and classical physics , which interpreted the structure of space-time as random and inalienable. [7]
The prevailing idea of cosmic changes is that the Universe is expanding at a constantly accelerating speed; moreover, it is clear that by tracing the history of the Universe in the opposite direction, one can find that at some point it was much denser. If true, the rainbow theory of gravity forbids a feature such as that postulated in the Big Bang theory. This indicates that, looking in the opposite direction, the Universe is slowly approaching the point of ultimate density, without even reaching it, implying that the Universe does not have a point of origin [3] .
Criticism
There are strict limits on energy-dependent light speed scenarios. [8] Based on this, Sabina Hossenfelder sharply criticized the concept of rainbow gravity, saying that “This is not a theory and not a model, but just an idea that, despite more than a decade of work, has never turned into the right model. It is not possible to combine rainbow gravity with a standard model. There is no known quantization of this approach, and it cannot be described at all by interactions in this structure. Moreover, it is known that this leads to non-locality, which are already excluded. As for me, no article should be published on this topic until these problems are resolved " [9] .
