How do you see the unity of all Physical Laws ?
I ask this question because between Real Laws
( Newton's , Maxwell's, Einstein's, Lorentz's,
Schrödinger's, Dirac's . . . .etc.) there are many 'black holes'
and ' white spots' ( time, dark energy, dark mass, graviton,
quark, Higgs boson, . . . and 1000 another elementary particles.)
Unity? That's news. But physics keeps striving to reduce the number
of equations necessary to describe everything -- so called unification.
It began when Newton unified gravity on earth with gravity in space.
Unification continued when Maxwell reduced all the experiments
on electricity and magnetism to just 4 equations.
It continued with Einstein's special relativity, which amounts
to the Lorentz transformation. 4 equations. You might say
it unifies space and time. General relativity unifies gravitational
mass with inertial mass.
Then equations of motion for atoms were described by quantum
mechanics -- such as Schroedinger Equation & later Dirac Equation.
These form the common unification of chemistry.
Then quantum electrodynamics was discovered, which unified
electromagnetism with the quantum theory. Some of theory's
predictions (such as the fine structure constant) have been
experimentally verified to something like 10 or 12 decimal places,
a huge measure of success for any physical theory.
Meanwhile the strong & weak nuclear forces were partly
de-mystified: The weak force was found to be unified with
electromagnetism (electro-weak force), while the strong nuclear
force involves quarks of various kinds, with specific rules of
interaction best described by group theory.
And so it goes. The 'holy grail' of physics is to reduce all
of existence (all interactions of all particles) into a single equation,
sometimes called "God's Equation" -- the ultimate unification.

i think there is unity in most laws but not all, after quantum physics
basically there is no real law, we think of time, gravity and matter
in certain ways but in reality they are random forces with mostly
predictable outcomes but not 100 %, then there is parallel
universes and things as such where physical laws go the
wayside , just like black holes. , so in reality , not much unity.

Their is the laws of the microverse and laws for the macroverse
(verse = universe) I wonder if they apply 100% at their own
extents and reduce (perhaps exponentially) as they come closer
toward the other one meshing in the in the middle. thus the
macrocosm still deals with quantum physics at
say .000000000000000000 00000000000 1% near the size
of say our solar system where "normal" laws of say gravity
exist at 99.9999999999999999 999999999% and vice versa
at say the size of an atom it is the other way...?????
?? hhmmmmmmmm?? ?? just perhaps.

Yours is a very profound question. I can tell from your question that
you are ready to be let in on the "Dirty Little Secret" of Theoretical Physics:
We have NOT yet figured everything out. The universe is governed by whole
sets of "Laws" that do NOT agree and are mutually exclusive.
This is a great embarrassment. We assume we live in an orderly, rational
universe that makes sense. Perhaps when Quantum Mechanics and
General Relativity are unified we will have a better answer to your question.

The LAWS must unify, or we are describing things that don't actually exist.

I think that now our Physics looks like the Augean stables.
And if we want to clean them we must start from
understanding not new but the old abstract models:
ideal gas, ideal black body, entropy, electrical harmonic
oscillators, point -particle . . . etc.
