Answer:
It depends
Explanation:
Even Newton's laws, valid nowadays and irrefutable for centuries, were corrected by Einstein in 20th century The validity is tested by how many proofs existed that the theory is right; furthermore, when there is proof that a theory is wrong, the proof itself must be tested and evaluated, as it could be inexact for various reasons.
As the example above, Newton's laws, as not perfect anymore in any circumstances (integrated by General Relativity), resisted dozens of tests and experiments to prove their wrongness.
