It is impossible to understand the phrase "space is inflating" without understanding Vector Calculus. People will try to come up with explanations... but there is a reason that civilization invented Universities... as human knowledge increases it takes a longer time to master it.
The detailed particle physics mechanism responsible for inflation is not known. The basic inflationary paradigm is accepted by most scientists, who believe a number of predictions have been confirmed by observation; however, a substantial minority of scientists dissent from this position. The hypothetical field thought to be responsible for inflation is called the inflaton.
How about saying physicists can't explain inflation, because it is a mathematical model which can't be explained in terms we can envision in reality. Or can it, and they just don't like what it looks like?
You can say that the top of the wing being curved causes lift. But that doesn't give you much of an explanation of Bernoulli, nor would it allow you to do any useful work in avionics. The Wright brothers spent a lot of time studying, and writing about mathematics... they did their homework.
Although no record of the exact calculations exists, the Wrights averaged a series of results
from a glider in 1902. Combined with their wind tunnel tests to determine cL and cD, by
directly measuring the drag on the glider using a spring scale and restraining ropes, they
were then able to directly calculate the Smeaton coefficient k from the equation for drag
[McFarland, 574]. 29
L = kSV2cL The equation for lift predicts forces, but does not give us an image. The wright brothers used real airfoils in wind tunnels. The wind tunnel was real, and they could see how it works. We can illustrate it simply in this animation. https://en.wikipedia.org/wiki/File:Karman_trefftz.gif
Atomic orbitals can be the hydrogen-like "orbitals" which are exact solutions to the Schrödinger equation for a hydrogen-like "atom" (i.e., an atom with one electron).
The Schrodinger equation, which also explains and predicts, is only mathematical with no structure in reality to explain it.
The Schrodinger equation provides a way to calculate the wave function of a system and how it changes dynamically in time. However, the Schrödinger equation does not directly say what, exactly, the wave function is. Interpretations of quantum mechanics address questions such as what the relation is between the wave function, the underlying reality, and the results of experimental measurements.
The equation cannot explain why the strong nuclear force exists, but it can explain what an atomic orbital looks like. https://en.wikipedia.org/wiki/Atomic_orbital#/media/File:D_orbitals.svg
This actually shows what orbitals for a hydrogen like atom looks like. Since the detailed particle physics mechanism responsible for inflation is not known, while the detailed particle physics mechanism responsible for lift and Schrodinger equation are known, what better place to speculate than on a forum. At least here you are anonymous, and your credentials (a doctorate or professorship in physics) are not on the line. So lets speculate what a higgs boson or the higgs field looks like. The higgs field and boson, more than likely have a physical structure that is underpinning the shape of the atomic orbitals, while also being the detailed particle physics mechanism responsible for inflation. What do you think it looks like?
