The wormhole idea may have started with Einstein and Rosen (ER) critiquing quantum mechanics; they regarded it as an incomplete theory.. They believed that quantum entanglement could hypothetically be explained by a wormhole between entangled quantum particles. Plainly that opens the way to fiction paradigms for star trek transporters sending people through shaped quantum wormholes.
A modern theory that may surpass the Lamda Cold Dark Matter CDM model is one that has space-time and all of the contingent-entangled Universe being comparable to an illusion that occurs on or from an underlying timeless realm. Today some believe it could be explained by the four-dimensional universe being somewhat like a physical projection or phenomenon from an underlying two-dimensional field. That is the Universe of four dimensions is comparable to an illusion or phenomenon made because the field fluctuations of the two dimensional field yield waves that become entangled at points as particles and so the extra dimensions exist in the entangled state. The new criterion would allow star-trek style transporters to relocate travelers anyplace in the Universe instantly. In a sense they would exploit quantum entanglement to disentangle themselves from local spacetime and reappear in another. More about that below.
ER=EPR stimulated, as I understand it, further ideas about wormholes between black holes and white holes. I hate to think about the way time is affected between the black hole and white holes in the wormholes. Some opinion based on ER is that the black white hole vector is the only form that wormholes could exist in space-time. One need put an asterisk next to many “only place” ideas obviously for they are difficult to prove.
There are other theories today about gravity and black holes instead of quantum gravity theories. One is that singularities don’t really exist in black holes and instead they stop reducing at a certain size and spew out their mass through the wormhole and white hole on the other end.
Quantum entropy is a new explanation for gravity that obviously isn’t proven yet. Yet it could provide another opportunity for faster-than-light-travel theory. One should be able to use a star trek transporter to reduce an individual to an unentangled state and bounce the information down to the timeless two-dimensional place that uplifts the contingent universe of four dimensions. Space-time in that timeless two-dimensional realm is quite different (no time and no distance in comparison to the four dimension realm). Then one need return the disentangled quanta to a different location in the Universe.
Here is some information about quantum entropy gravity theory summarized by Gemini-
“The "quantum entropy theory of gravity" is a framework that proposes that gravity can be derived from quantum relative entropy, a measure of how different two quantum states are. This approach attempts to unify quantum mechanics and general relativity by treating gravity as an emergent phenomenon arising from the differences in information content between spacetime and matter.
Entropy and Gravity:
The core idea is that gravity isn't a fundamental force but rather a consequence of the increasing disorder (entropy) within a system. In this framework, the geometry of spacetime is related to a quantum operator, and the difference between the natural spacetime metric and the metric induced by matter fields is quantified by quantum relative entropy.
Bridging Quantum and General Relativity:
By linking gravity to quantum information, this theory aims to reconcile the two seemingly incompatible theories of quantum mechanics and general relativity.
Modified Einstein Equations:
The entropic action leads to modified Einstein equations that, under certain conditions, reduce to the familiar equations of general relativity. However, it also predicts a small, positive cosmological constant, which aligns better with the observed accelerated expansion of the universe than other existing theories.
The G-field:
The theory introduces a G-field, an auxiliary field acting as a Lagrangian multiplier, which plays a crucial role in the modified gravity equations and potentially offers new insights into dark matter.
Emergent Gravity:
This approach suggests that gravity might be an emergent phenomenon, meaning it arises from the collective behavior of smaller, more fundamental constituents of spacetime.”
