If we had enough axioms about reality could mathematics replace physic

In summary, mathematics has the ability to prove and disprove things, while science can only disprove. This is because mathematics has a set of starting axioms, while science is limited by the constraints of the physical world. It is possible that all laws of physics could be proven using mathematics if we had enough axioms for our world, as Hilbert's sixth problem suggests. However, even if we were able to completely axiomatize the world, it may still be too difficult or even impossible to make accurate mathematical statements due to the complexity of the universe. While approximations can be made, they are not considered the same as mathematical derivations from axioms.

Math is able to prove and disprove things while science can only disprove. The reason we can't prove much about the actual world is because unlike in mathematics we don't have enough starting axioms. If the math world isn't real and is just an object of the mind it would make sense that us humans can definitely prove things in it because it's a product of our mind. However the actual world isn't a product of our mind so maybe we are just not smart enough to prove much about our reality. Do you think all of the laws of physics and more can be proved using mathematics if we had enough axioms for our world?

I think it's true in principle. This was one of Hilbert's main problems by the way: http://en.wikipedia.org/wiki/Hilbert's_sixth_problem

However, let's say that we can completely axiomatize the world, then it might still be far too difficult or even impossible to make many good mathematically precise statements. For example, even if you just assume CM, then the three body problem becomes impossible to solve analytically. So it already is difficult to describe the motion of three bodies. Let alone describe the motion of all particles in the universe. So even though we can find the basic differential equation that underlies motion, it might not be possible to solve it. So it might turn out we find the basic axioms, but they involve equations we can't solve.

Of course, it's possible to give numerical answers by approximations. This is a very useful tool. But I don't count it as a mathematical derivation from the axioms in the same way that group theory or analysis is.
 

1. Can mathematics completely replace physics?

No, mathematics and physics are two distinct fields that complement each other. While mathematics provides the tools and language for describing and predicting physical phenomena, physics is concerned with understanding the fundamental laws and principles that govern the behavior of the natural world.

2. How many axioms would be needed for this replacement to occur?

It is impossible to determine the exact number of axioms needed as it would depend on the level of detail and complexity of the physical phenomena being described. However, it is likely that an extremely large number of axioms would be required to cover all aspects of reality.

3. Would this mean that all physical laws are reducible to mathematical equations?

Not necessarily. While mathematics can provide a framework for describing physical laws, it does not necessarily mean that all physical phenomena can be reduced to mathematical equations. There may be certain aspects of reality that cannot be fully captured by mathematics.

4. How would this replacement affect our understanding of the universe?

If mathematics were to replace physics, it would greatly enhance our understanding of the universe by providing a more unified and precise framework for describing and predicting physical phenomena. However, it would also mean that our understanding of the universe would be limited to what can be described mathematically, potentially leaving out important aspects of reality that cannot be captured by mathematics alone.

5. Is this idea widely accepted in the scientific community?

No, this idea is not widely accepted in the scientific community. While some scientists and philosophers have proposed the idea of a mathematical universe, it is a highly debated and controversial concept. Many scientists believe that mathematics and physics are two distinct fields that cannot be reduced to one another.
