I found this fascinating story The Fundamental Constants Behind Our Universe at medium.com's "Starts with a Bang" column. Ethan Siegel posits:
But the Universe itself experiences continual growth, constant change, and new experiences all the time, and it does so spontaneously.
And yet, the better we understand our Universe — what the laws are that govern it, what particles inhabit it, and what it looked/behaved like farther and farther back in the distant past — the more inevitable it appears that it would look just as it appears.
[...] We’d like to describe our Universe as simply as possible; one of the goals of science is to describe nature in the simplest terms possible, but no simpler. How many of these does it take, as far as we understand our Universe today, to completely describe the particles, interactions, and laws of our Universe?
The answer? "Quite a few, surprisingly: 26, at the very least." He then goes on to explore what these are and how they are computed.
Sadly, we don't know enough to be able to predict everything. As the article notes, there remain problems with explaining CP violations, matter-antimatter asymmetry in our Universe, cosmic inflation, and what dark matter actually is.
Separately, but related: many years ago I came upon a site that provided interactive exploration of the scale of things in the universe from Planck length on up to the the visible universe. (And, no, it was not powersof10.com) I have a niece who is curious about such things and I would love to share such a site with her. Sadly, I can no longer locate a link. Any suggestions?

Maybe there just are 25 and there's nothing to discover unifying them or expressing one in terms of the others.
There's an interesting historical analogy with Euclid's five postulates where a heck of a lot of human brain power was burned trying to express the fifth in terms of the first four, never got much of anywhere. I think Peano's axioms work the same way, there's five, not six, not four, just deal with it.

Actually, it got us through non-Euclidean geometry and Riemannian geometry all the way to General Relativity.
If people had never put thought into that axiom, they probably never would have recognized that it can make sense to assume that this axiom simply does not hold.
The Tao of math: The numbers you can count are not the real numbers.

Well, yeah, the analogy breaks down in that I shouldda specified traditional plane geometry. The analogy of non-plane geometry would be some kind of multiverse imaginings, I guess.

Or, as Maxwell Demon said, general relativity. Come to that, if you ever try to do geometry on the surface of a sphere, you're violating one of Euclid's principles. The maths to do that only came because people attacked it.

The 25 fundamentals don't appear to cover "chocolate", that is to say the subjective experience of it (nor many of the different things it means to different people).
In theory a universe with those 25 fundamentals and our known laws of physics does not require[1] the existence of consciousness nor "chocolate" and other subjective experiences (Qualia: https://en.wikipedia.org/wiki/Qualia [wikipedia.org] ). I cannot prove to others consciousness exists and yet I know for sure it exists.
Some scientists think consciousness is a fundamental or even universal: http://www.scienceandnonduality.com/consciousness-as-fundamental-building-in-the-universe/ [scienceandnonduality.com]
[1] You could in theory have a simulation of the universe with all these fundamentals and laws and there isn't a need for consciousness to exist is there? But in this universe it somehow exists. If you did the simulation with pen and paper (or with a bunch of rocks: https://xkcd.com/505/ [xkcd.com] ) would consciousness still be emergent?
Or am I the only conscious person in this universe and the rest of you aren't and are: https://en.wikipedia.org/wiki/Philosophical_zombie [wikipedia.org]

Can't overlook self deception as a possible failure mode of the argument.
As far as memes go your assumption is invalid as it seems to be an epidemic meme, its hard to find an individual self reporting as uninfected, and it mostly seems to be transmitted by speech, so obviously somebody is telling some persuasive stuff about it somewhere...

My own consciousness is the only thing I can be 100% sure exists. Can't be as sure of everything else.
