Quantum Spinning Bucket Experiments
Newton’s spinning bucket experiment efforts, like those of the pre-Socratic philosophers Parmenides and Heraclitus (no they weren’t partners) examined the nature of the volume that is space. We would say space-time rather than just space, yet that may be a convention too as time seems like a secondary rather than a primary quality of space. Time cannot appear without mass, energy or matter to act upon with differential values in relation to the location and characteristics of mass.
One might wonder about the nature of the volume that contains a Universe or Universes or any possible configuration of Universes including a Multiverse. Typically physicists tend to describe the configuration of matter (or anti-matter) and energy existentially and phenomenally as if only it existed rather than volume of space. It seems rather plain that a volume of space- truly empty void- that hosts the Universe, doesn’t figure into calculations of modern cosmology. Instead various fields arising from an initial solitary unified field; one indubitably made of energy- a singular sort and condition of energy pervade the expanse of the Universe. The Universe exists only as far as the fields expanding from the initial singular unified field at T=0 (Time equals 0) have traveled.
There are many interesting points about the four basic fields of the Universe that one might consider. Gravity is said to have split off first followed by the strong force. The strong force split and released the electroweak force dividing into the Weak force and electromagnetism as the Higgs Field arose. Apparently each of these fields must equally pervade the entire Universe, yet they may be induced local field phenomena that appear in the presence of entangled mass and energy.
What is called space-time is different than the volume of void that hosts it. Space-time mass and energy is regard as having four dimensions, yet no one knows what a dimension is or if it is made of anything. The field-energy filling the entire Universe, or making the entire Universe is thicker and thinner in various regions as far as mass, dark matter, energy and dark energy go. Overall one might expect that it logically should be generally equal distributed in all directions from the T=0 expansion thought not exactly. Because energy is charged it could cancel out through various means such as matter and anti-matter contacts and spin anisotropy and generate uneven distributions. It is also the case that energy becoming entangled in the Higgs field generates the appearance of mass, and mass is a secondary characteristic of the fields that comprise the Universe rather than primary.
It is possible that there is a difference between primary and secondary fields and field phenomena. The speed of light is the fast possible speed for matter or energy entangled in the Higgs field, yet the primary fields are not subject to the laws of general relativity perhaps- unlike possible secondary field like electro-magnetism. Gravity itself may be just a field generated phenomena and a secondary phenomena without a graviton to transfer its power.
Some wonder much about the spooky action at a distance of quantum entanglement. Mass in one location may quantum entanglement with mass at at a distance. Perhaps the concatenated quantum entanglement of mass with other mass at a distance faster than light creates a secondary effect of mass attracting other mass at light speed. Light speed would be slow in comparison to the faster than light status of primary fields hosting the matter and sub-light speed energy of the Universe. Gravity waves would be generated by mass quantum entanglement comparable to the way that waves may be generated in the water of a swimming pool by a mechanical push at one end of the pool. Gravity waves in thee normal human universe of experience reflect mass quantum entanglement occurring in the primary fields faster than light and lacking the spatial distance values inherent in the subluminal Universe.
Still it is interesting to consider a bucket whirled at the end of a rope half full of water that is in empty space. There is a problem with the definition of empty space affecting the outcome of the experiment. If the bucket was spun in this Universe it would be acted on by the fields pervading this Universe. If it was truly in the void that hosts the Universe and the Universe did not exist (just the bucket and the experimenter) then the experiment and the bucket would be quite anomalous. There would be micro-gravity in this Universe, while in the true void not even the experimenter or bucket could exist- since they are generated from quantum field effects of entanglement in a Higgs field.
Some experimenters and theorists have conjectured about extra-dimensions- maybe smaller ones, that might exist in the Universe in order to explain the structure of matter. Besides the obvious problems that appear when considering time as a dimension with factors of general relativity at the quantum scale there is the problem of the nature or the void that hosts the Universe? How many dimensions does it have and could a Universe appearing within it have more dimension than the pure space-void itself.
Some physicists have said that a pure-void does not exist and that only matter and energy exist even if it is stretched very thin. Plainly though fields are primary and exist although in what true form is to a degree still unknown. Fields exist and dimensions exist at least within the space-time of the Universe where matter and energy arise in a Higgs field.
Maybe the host fields don’t have the same dimensions as the contingent Universe we live in (entangled as mass in a Higgs field). Because they are not like this Universe spatially, there is no distance comparable to the scales of this Universe. Light speed is not a meaningful speed in fields without distances based on mass relations (a contingent phenomenon). The fields as separate from the on singular field may be stacked together like layers in a computer chips and convey information in a different way-for a trivial example horizontally and vertically rather than in a simple linear progression. Non-linear time passage based on a stacked, layered field information would perhaps be different than that of inertially driven mass with relativistic time such as occurs with special relativity combined with general relativity.
I wonder though about the basic question of can this Universe have more dimensions than that of the true void, and I think the answer is no. If a true logical void has just three dimensions and one of time then it probably wouldn’t be possible to construct a 23 dimension or 230 dimension material Universe within it. Mathematicians obviously can construct multi-dimensional models simply changing a number value- a variable. That sort of Multiverse might have no corresponding real value in the world. Aristotle believed that words have a necessary relation to real objects and that is logic would therefore bring true results when formulating logical equations about the real world. Subsequent logicians discovered that words and material objects haven’t a necessary relationship at all. That circumstance probably exists between mathematical models of quantum cosmology and actual quantum cosmology. It is a great tool that applied probabilistically for making judgments provides valuable insight, yet fails the kind of rigorous logic that Aristotle sought when inventing classical logic (although some dispute that he invented classical logic).
A logical volume of absolute space would seem to have three spatial dimensions. A physicist friend of Einstein's said that human life couldn’t exist in a Universe with more than three dimensions and one of time. That judgment was made concerning the structure of quantum particles yet if one consider a true-void primary empty space without fields with more than three spatial dimensions- perhaps six or more it becomes increasingly difficult to imagine any sort of coherent Universe structure existing within it.
Could dimensions rather than being fields of some unknown nature that exist for true void be better compared to vector-directions? Within a three-dimensional unbounded true void their might be a veritable Cantorian infinite number of vector-dimensions radiating out of some central point (for simplicity in visualizing the structure) or existing in an infinite number of other ways with the straight spaghetti strands of some thicker or thinner than others. So while a Universe built from three strands of spaghetti-like dimensions added together selected to build a universe in, there could be thinner, smaller spaghetti strands mixed with it at the quantum level to support loop quanta or something like mini-spaghetti strings. Who can say for sure. A Quantum Chef of spaghetti-sauce may explain the secret recipe someday.
