"...
string theory has undergone many developments and changes. By the mid-1990s, the theory was developed in
5 different independent string theories, but in 1995, it was realized that all versions where different aspects of the same theory named
M-theory (M for “membrane” or the “mother of all string theories”).
It has now become the focus of
theoretical work for its success in explaining both gravity and the inside of an atom at the same time. One of the most important aspects of the theory is that
it requires the
11-dimensional space with one time coordinate and 10 other spatial coordinates. ..." -
How Many Dimensions Are There? 11-Dimensional World and String Theory - Learning Mind
There is an a priori involved. It "requires". The maths didn't lead them, their 'theory' (aka 'guess') requires the direction of at least 11 dimensions (10 +1). There is no scientific evidence or repeatable demonstrable cause and effect involved. It's just numbers on a chalk board.
"... By the 1960s, physicists had discovered two additional forces of nature, both operating at the subatomic scale. Called the
weak nuclear force and the
strong nuclear force, they are responsible for some types of radioactivity and for holding quarks together to form the protons and neutrons that make up atomic nuclei. In the late 1960s, as physicists began to explore the new subject of
string theory (which
posits that particles are like minuscule rubber bands vibrating in space), Kaluza’s and Klein’s
ideas bubbled back into awareness, and
theorists gradually began to
wonder if the two subatomic forces could
also be described in terms of spacetime geometry.
It turns out that in order to encompass both of these two forces,
we have to add another five dimensions to our mathematical description.
There’s no a priori reason it should be five; and, again,
none of these additional dimensions relates directly to our sensory experience. They are
just there in the mathematics. So this gets us to the 10 dimensions of string theory. Here there are the four
large-scale dimensions of spacetime (described by general relativity), plus an extra six ‘compact’ dimensions (one for electromagnetism and five for the nuclear forces), all curled up in some fiendishly complex, scrunched-up, geometric structure. ..." -
How many dimensions are there, and what do they do to reality? | Aeon Essays
Notice, the maths describing the natural universe didn't originally show anything of this. It came about by several "theories" and was
placed into the maths at an attempt
to unify all theories and known phenomena and guessed at phenomena. There was no evidence in any of it to even suggest that it could, should or ought to be unified in the first place. They simply tried to smash
their theories (guessing) and maths together. In other words the math did not lead them, they lead the maths based upon how they thought the universe began and ran (beginning with their Big Bang and expansions).
"... More confusion about higher dimensions was generated in the press beginning in 1984, when physicists became excited about so-called
"string theory.'' Physicists have
never been able to work out a theory of gravitation that is consistent with quantum mechanics and also has some feature that indicates it might be uniquely correct! String theory provided a geometrical description of quantum processes that incorporated gravity very naturally. But three other forces besides gravity are known.
Borrowing the idea of Kaluza and Klein, physicists
incorporated the other three forces and their "couplings" by adding space dimensions— the only thing you can do in a theory that is purely geometric. A typical string theory had 9 or 10 space dimensions and 1 time dimension.
The extra space dimensions had to be there to incorporate phenomena other than gravity geometrically, but they could not "actually'' be there or the theory would not have worked. ...
...
So far, physicists have no concrete idea as to what a unified theory of all quantum processes and gravity might look like, but it is certainly possible that such theories will remain multi-dimensional. It is important to realise that these theories have absolutely no contact with experiment at present. There is no experimental evidence of any kind whatsoever for dimensions beyond the usual four." -
Higher Dimensions?
"... Let start with its hypotheses.
Can we measure or observe the one-dimensional vibrating strings of energy that form the core hypotheses of string theory? The answer is no, and that is an emphatic no. We cannot measure them with today’s science, and it is unlikely that we will ever be able to measure them. According string theorist the one-dimensional vibrating strings of energy are about equal to the Planck length, which is the smallest length science theorizes to exist. It is equal to 1.616199(97)×10^−35 meters and is defined from three fundamental physical constants, which I won’t to into here for the sake of brevity.
The problem is that today’s science is unable to measure anything smaller than 10^-18 meters, which is billions of times larger than a Planck length. Many in the science community
do not think we will ever be able to measure a Planck length, regardless of improvements in measurement technology.
Therefore, the first significant problem with string theory is that its hypotheses are not verifiable. ..." -

It's all just mental brain-farting, that is vomited upon a blackboard, based upon a disproven, or rather falsified, myth of origins that began from a religious amalgamation from a known order of charlatans in the anti-christian system that denies the plain word of God by its utter disbelief therein.
