The laws of thermodynamics contradict themselves unless dualism is true, some kind of dualism in physics.
What do you mean by this?
That description is so vague as to be meaningless. There's a link to wave-particle duality, but that's
standard physics.
which would make the laws of thermodynamics a religion instead of science
Yeah, not so much.
Physics means how the universe works.
If there is no dualism in physics, then by definition, there is only 1 kind of thing in the universe.
This is such a trivial definition of "dualism" that it's
obviously true of physics as it stands today.
Mass and energy are interchangible if you do certain things
But linear momentum and energy are not. Angular momentum and energy are not. Charge and energy are not. All of those things need to be conserved
independently of each other. So obviously there isn't "only 1 kind of thing in the universe."
Its a common idea that everything is made of vibrating strings or surfaces or other equations.
String theory is as of yet untested. It is, at this point, a purely mathematical theory, with no connection to any experiment, and so should not be considered a physics theory.
The "big bang theory" says the "laws of physics" changed during the first fraction of a second of the big bang, or that is where they formed into what they are now.
Not exactly. Rather, the big bang theory cannot predict what happens at the singularity. We don't know if any laws changed.
There is also speculation about the laws of physics changing or not working the same way in some parts of black holes or when enough particles simultaneously hit each other at near the speed of light.
No. That is a mischaracterization of our expectations. Physicists don't expect that the laws actually change, they expect our current
theories to become inadequate. But the laws of physics are whatever they are, regardless of the circumstance.
Perhaps an example would help illuminate the difference. Special Relativity and Newtonian mechanics give two different equations for the momentum of a moving object. We know that Special Relativity is more accurate, at all speeds. But at low enough speeds, Newtonian mechanics still provides an excellent approximation to the special relativity equations. It's not that physics
changes as you go to high speeds, it's that the old theory becomes inaccurate at speeds close to c. Note that accurate vs. inaccurate is
different than right vs. wrong: the Newtonian equations are
wrong at all speeds, but it's
accurate at low speeds. Similarly, our current theories are
accurate where we can currently test them, but under extreme conditions which we cannot yet test, they may become inaccurate.
Thermodynamics says disorder increases over time
No it doesn't. It says entropy does. I know how to define and calculate entropy rigorously. I do not know how to define "disorder" rigorously.
and eventually spreads evenly through the whole universe
Nope, doesn't need to do that.
But the third law of thermodynamics says very accurately what the universe will become and continue to be forever after that. It says heat will spread out evenly to everything and forever approach some constant minimum heat.
If you want to talk about thermodynamics, especially if you're going to be making bold claims like it being possibly wrong, you need to be precise. And you are NOT being precise. In fact, you are using the term "heat" completely wrong.
Heat is NOT thermal energy, and it is NOT temperature. Heat is the
transfer of thermal energy. If the universe experiences "heat death", it will approach some uniform temperature, but
heat will go to
zero.
That is a very well defined and accurate pattern, which contradicts the claim of thermodynamics that patterns will become disorder.
Again, we have the problem that thermodynamics doesn't describe disorder, it describes
entropy. And a uniform temperature IS a maximum for entropy. It's rather easy to demonstrate this with statistical mechanics.
I did not take thermodynamics out of context.
You just took it wrongly.
