Answer:
No scientific theory can ever be proven true.
Physics has two tremendously good theories: Einstein’s Theory of Relativity, and Quantum Field Theory.
These have been around for about a century and no contradictions have shown them to be false.
And yet these theories contradict each other, so one or both will eventually be supplanted.
Step-by-step explanation:
Science is based upon evidence. And no matter how much evidence you have for a theory, it is impossible to say it is true.
Thus, truth is beyond what science if capable of.
