Only one if the theory is correct and can stand up to scientific testing. The number of theories really means nothing other than it gives more ideas to test. You could have hundreds of theories and they could all be wrong.

Does scientific theory have more chemistry and physics than scientific law?

A scientific theory is a theory, no given proof of being a fact, a scientific law is what always happens, essentially a fact. Both is in chemistry and physics. The theory of gravitation happens before it became the Law of gravitation. Scientific theories and laws are similar except laws were proven to be recognize as a fact.


What do scientists do when the evidence from experiments does not support a scientific theory?

They do the experiment again, double check all their calculations, then they come up with a new theory if it's necessary. That's why there's no such thing as a scientific fact, only scientific theories.


Can theories be disproven?

Yes, theories can be disproven if evidence is found that directly contradicts their predictions or explanations. This is a fundamental part of the scientific method, where theories are continuously tested and revised based on new evidence.


Does a scientific fact and a scientific theory carry the same weight in the scientific community?

No, a scientific fact is a direct and observable observation while a scientific theory is a well-substantiated explanation of a natural phenomena based on evidence and experimentation. Scientific theories are more robust and comprehensive than facts as they explain why a phenomena occurs rather than just stating that it occurs.


What is the difference in theory and scientific law?

A scientific law is an indisputable fact: there are no observances dictating it. For example, gravity is a scientific law. A scientific theory is simply a generally accepted explanation for a particular phenomenon or idea that cannot currently be proven or disproven. The structure of the atom and evolution are theories.

Are theories ever changed?

Theories are changed constantly. In fact, many known theories today are only theories from that of someone else only with an improvement. Many scientific theories for example are developed that way. Take this for example, many thought the world was flat, that theory developed (changed) to the fact that the world is round instead of flat. Current theories that are changing daily-- "How was the universe formed?" "How did life begin"? "Was there ever life on Mars"? "What is all that DNA for?" "How do we make more efficient solar cells?" "What will happen with global warming, and how can we modify it?"
