If the "reality" to be calculated is not too complex, then it currently works with simple mathematics;-)
An example for mathematical nonsense, which mathematicians do not have to notice: The "corona"-"incidence" is calculated incorrectly. Not unintentionally. Moreover, we take as a basis of this calculation a count of "cases", where "cases" is not clearly defined. Thirdly, the "cases" are based on measurement methods that do not prove "virus" or disease or infection or anything else. All the beautiful many numbers and calculations are therefore: worthless, meaningless: bu....it;-) So mathematical bu....it;-)
Unfortunately, representations of numbers and diagrams and hospitals and nurses and painted ideas of "viruses" lead to a "real world view", bu....it, which is also no longer to get out of the heads;-)
And now transfer this example into "physics". We have only - perception and psycho-social mechanisms, conditions first of all not discussed - objects and (also their) change. What all are constructs - NOT reconstructions! - which are mentally created by humans to be able to "grasp" "world";-)
Maintaining logic in "complex world" comes BEFORE "mathematics": Man should already know, what he "mathematics" "applies"-)

WTH?
I was talking physics... not statistics used in the bio-chemical sciences.
Often times the "solution" to a problem will offer some components that are "buried in the noise".
The most classical example ( from Mechanics ): A boat is moving through a lake in a straight line, there is no wind, there are no water currents, at some point, when the boat is moving at a constant velocity, the motor (or oars) stops.
Q1) How long will it be before the boat stops?
Q2) How far will the boat go?
A1) The boat will never stop ( for a mathematician ).... for a physicist it will come to a stop when the movement is imperceptible.
A2) The boat will travel a finite distance that can be measured.
A2 causes no issues for the mathematician... but A1 throws them into fits of impudent rage... you see them stuck on the middle of the lake while the physicists got to the other side, are having a BBQ and drinking some chilled beer.
On GRAVITY..
General Relativity claims that space is warped by gravity... or rather, that gravity is a of bending space. BUT, if 3 dimensional space is "bent", I posit that such requires at least ONE more spatial coordinate for the 3D to bend around.... huh? Likely 3 more... so that makes it into a 7 coordinate system.. our 3D, the additional 3D about which "our" 3D bends and the spacetime coordinate. That's just for astrophysics.... the Standard Theory requires at least 8 dimensions. I am not quite sure if they have tied general relativity with the Standard Theory.
Also, if gravity is created by out of balance forces within the nucleon (graviton-nucleon)... why do we see gravity waves in areas that have no mass ( or energy ). Is the gravity wave then composed of mass less (energy only) 'nucleon like' particles that move at the speed of light and that, like electro-magnetic waves ( photons ) self propagate through space?
Or are these "graviton-nucleons" in the other 3D spatial coordinates and what we see in "our" 3D is the bending causes by the particles.
Graviteons.

Speed - (mental result from tracing of) change. No model feasible. Concept.
Energy - (mental result from tracing of) change. No model feasible. Concept.
Mass - (mental result from tracing of) change. No model feasible. Concept.
...
Space (not room, not volume) - (mental result from tracing of) "positioning", "change". No model feasible. Concept.
Time - (mental result from tracing of) "change". No model feasible. Concept.
Space-time - see above ;-)
Also space and time and space-time, and also "universe"! are NOT physical "phenomena"!
They are auxiliary constructs to deal "with" "world":
"ONE, UNI, (collection of) ALL things":
"UNI-verse",
"ALL"-)

Even worse than nonsense is a wrong-sense resembling the truth.
Speaking of wrong sense, see right above your post.
Space, time, energy, speed, mass; all fake.
If ignorance is bliss.....

Mathamaticians are intelligent people with nothing else to do. Physicist are curious people trying to compete mathamaticians. Engineers are practical people who not only doesnot care but never really are good in mathamatics. Technecians like me are like always wrong but always with the loudest of the all.
Even in a 3D universe I feel completely out of my 'depth'! 😀
One hypothesis states that gravitons may allow us to feel the pull of gravity from mass located in extra dimensions that are invisible to us.
These extra dimensions would be very small compared to the usual dimensions of length, breadth and depth to which we are accustomed.
These are referred to as 'rolled-up' dimensions. The analogy is that of a tightrope walker confined to walk in a straight line while an ant can also walk round the circumference of the tightrope wire, thus having access to a small "rolled-up" dimension not accessible to the tightrope walker.
Get two objects close enough together so that they lie within a 'rolled-up' dimension and the hypothesis predicts there should be a greater than normal gravitational attraction between them.
In order to search for these extra dimensions, physicists smash particles together in the LHC and look for deviations from the inverse square law of gravitation.
More here: https://www.pbs.org/wgbh/nova/article/how-many-dimensions-does-the-universe-really-have/
P.S. I read it in order that others don't have to! 😉
Compete? Why would we want to compete with such?
To wit:
Technicians: the best at soldering, best equipment, microscopes. Blue lab smocks with their name on it.
Engineeers: not too bad. White lab smocks with their name on it.
Physicists: a few cold solder spots, depending on how much beer they had the night before. Guest white lab smocks.
Mathematicians: burn their fingers and the house down. No clue about ESD, think wave soldering is a good set of waves at the Newport Beach jetty.
(1) Have you read the book Flatland by Edwin Abbott Abbott? Other dimensions might be completely incomprehensible to us.
(2) CERN and LHC are just an example of "Big Physics" as practiced by the Euros. It's a Works Programs for physicists that don't want to work in R&D. Y(Ou know... "WORK"...
(3) I quit watching NOVA when they always slip something about Climate Change even when discussing ancient Roman villas or sub atomic spin.
I bought the 'Kindle' version some time ago, but have yet to read it in full.
The price has gone up from the 49p I paid for it! https://www.amazon.co.uk/Flatland-Romance-Dimensions-Classic-illustrated-ebook/dp/B0B6Q98K67
The book describes the journeys of A. Square, a mathematician and resident of the two-dimensional Flatland. Square has adventures in Spaceland (three dimensions), Lineland (one dimension) and Pointland (no dimensions) and ultimately entertains thoughts of visiting a land of four dimensions.

Yes. And to follow up on that, Rudy Rucker (Professor Rudolf Rucker) has written a number of science fiction and mathematics books that extend the concepts in Flatland.
Well worth checking out. The SciFi is particularily rich in ideas that can be another StrarTrek communicator/iPhone moment. White Light and the Software/Hardware/Wetware trilogy stand-outs to me. The world needs Wendy Meat.

I wanted to bring Science Fiction into this forum... but didn't want to complicate things and I wasn't quite sure it belongs in this forum. As it is, I think we're sort of pushing the boundaries of DIYAudio discussing Physics.
I mean, NP sort of thinks that DIY is not good at differential calculus... hmm...
https://audioxpress.com/article/Interview-with-Nelson-Pass
"...If you want to communicate with DIYers, you depend more on colorful analogies, a little hand waving, and very little differential calculus..."
Now, I think NP is underestimating the intersection of the sets in the DIYAudio forums.
There is a wonderful world out there in Science Fiction. I got lots of books on the shelves.

Let's say we tolerate them because sometimes they come up with some ideas that are useful to do Physics.
Wendy's was due to open in Scotland as part of a UK push, but I'm not aware of an outlet existing here yet.
Just what we healthy eating Scots need - square hamburgers!
Something to do with Facebook changing its name to "Meta" I read.
Had I watched Nova "Einstein's brain" in 1971, I might have passed Modern Physics 405 with a B instead of a D-. The professor thought a few equations explained everything. I totally messed up the spaceships passing problem on a test. Turns out Einstein was a visual thinker, like me. Nova showed the thought problems visually. The Tensor analysis in the papers came from a mathematician down the hall.
I had to transfer to UH where undergrad physics ended at Maxwell's equations. Which the prof explained in actual English, instead of squiggles on a black board. What is a laugh, Rice was teaching the 8-fold way model of partical physics, while UTx 165 miles away was publishing the Standard Model. I couldn't afford the room & board at UTx. I paid cash from work savings for college, and there was a draft deferment involved while Viet Nam was going on.
I'm so concerned about global warming I quit driving a car. 70 miles a week in summer on my electric bike shopping, meeting, & commuting to summer camp. I use 1/3 the electricity of an "efficient house" in my neighborhood, according to Duke Energy. What the biking is doing to A1C, cholesterol, weight, rest pulse, I might live until 2054 and suffer the heat & violent weather along with the grandchildren.

Not the same Wendy’s.
I will note that a friend, the fellow that invented teh scroller-roller, was one of the developers of their technique to not have to freeze the hamburgers. A vacuum thing as i understand.
Wendy Meat, as developed by Wendy, a scientist on the moon, is meat that grows as a fruit on trees. One of the favorites included her own genes, making it sort of canabilistic.
dave
BTW: of all the fast food places here, Wendy’s is the most tolerable.
On the subject of burgers.... In'N'Out. Double Double, protein style, grilled and fresh onions, mustard.
No contest.. We got one two miles down the road... grab a box of those, with fries, bring it home, get the ketchup and sriracha, open a bottle of good Santa Ynez Valley Pinot and serve. It includes its own salad!
Wendy Meat...??.. Peter F. Hamilton... The Reality Dysfunction? His books on my shelves. Awesome.
I'm afraid the Western Global Oligarchs want us to eat Soylent Green... while they gorge on aged ribeye roasts.

I get a bit frustrated at some of the ideas put forward here:
Is this Larry Niven Sci-Fi RINGWORLD Idea going to WORK?
My opinion is that it will self-destruct as soon as you breathe on it! Many design faults there...
Looks Symmetrical enough, but Symmetry breaks in the Real Universe:
Consider Neutral Pion Decay:
https://en.wikipedia.org/wiki/Pion
Just because the Reduced 3-body problem is solvable, doesn't mean an Hexagonal or Higher Symmetry solution won't shake itself apart:
This Silly bit of Space Engineering will end in Failure, IMO. 🙄
https://www.quantamagazine.org/new-math-shows-when-solar-systems-become-unstable-20230516/
I am a realist. Much as I enjoy Conservation Laws and Symmetry.
IMO, 1915 was the Greatest Year in Mathematics and Physics. Brought us General Relativity too. After that we have got a bit stuck. 🙂
