Conventional physics emphasizes experiments verifying objective reality but both quantum mechanics (QM) and originator of the multiverse hypothesis Hugh Everett suggest there's no such thing as objective reality.
Regarding QM - if quantum superposition is taken to its logical extreme, everything in the universe would affect everything else. Regarding Everett - his idea of the universal wavefunction says the observed and observer are all mixed together. These two references mean an experimenter's consciousness can never avoid influencing (technically, biasing) an experiment.
Physicists would be aware of these QM/Everett things but they seem to be unconsciously reverting to a classical view in which objective reality exists in all space-time, and not just in the limited perceptions of humans or animals. Our restricted senses (along with the limited technology and mathematics developed by humans to date) might view a quantum superposition where everything, including consciousness, fills all space and time very differently. For example - instead of occupying the whole of spacetime, a subatomic particle could be interpreted as being in more than one place simultaneously.
Another instance of quantum mechanics being re-interpreted: The ones and zeros of binary digits are compatible with quantum mechanics and may be referred to as the Hidden Variables which Albert Einstein advocated to complete quantum physics, and to give its calculations an exactness which would bring a hidden order to its chaotic randomness and superficial uncertainty. If the universe can be quantized and viewed as comprised of infinitesimal ones and zeros, how could it not obey quantum physics? And if those ones and zeros are all ultimately connected by Quantum Gravity to make everything in space and time parts of a unification, waves and particles could never be separated but wave-particle duality would rule.
The precise, merely superficially probabilistic Quantum Mechanics proposed here unites each quantum object in space, and in every period of time. Macroscopic objects are composed of quantum ones and the two scales should be unified by a QM that produces exact results and is as applicable to the micro as much as it is to the macro. Unification of the microscopic and macroscopic in all of space and time can be regarded as only one point ever existing (a state reminiscent of John Wheeler and Richard Feynman speculating that the universe consists of a single electron zigzagging through time). This might be termed unipositional quantum mechanics in which transmissions throughout spacetime are instantaneous. If signaling can be instant, distance may be an illusion, making intergalactic travel feasible and eliminating all “distance” between past/present/future periods of time).
It's plausible that quantum entanglement by "advanced" and "retarded" components of electromagnetic and gravitational waves will play a role in this UQM. In 2008's "Physics of the Impossible", Michio Kaku writes -
"When we solve (19th-century Scottish physicist James Clerk) Maxwell's equations for light, we find not one but two solutions: a 'retarded' wave, which represents the standard motion of light from one point to another; but also an 'advanced' wave, where the light beam goes backward in time.”
(In 1925's "Electrodynamics in the general relativity theory", George Yuri Rainich discovered that Einstein's equations state gravitational fields possess enough data about electromagnetism to allow Maxwell's equations to be restated in terms of them. Therefore, gravitational waves may likewise have retarded and advanced portions.) Advanced waves were much loved by Richard Feynman. They travel back in time and when combined with the retarded waves which go forwards in time, their entanglement would result in an "eternal present" necessary for time travel.
John G. Cramer wrote in his 2022 article "Advanced Waves Detected" - “In summary, it appears that advanced waves do exist and have been detected. Much more work must be done to ensure that this effect is real and can be extended, but the physics implications are gigantic.”
