Is it possible to prove, for certain, that a scientific theory is true?
A) Yes, by means of a single confirmed experiment that verifies the theory.
B) Yes, by carrying out a sufficient number of experimental observations.
C) Yes, by deducing it logically from other scientific theories that are known to be true.
D) No, because it is always possible that a future experiment will disagree with the theory.
E) No, because of the experimental error, or uncertainty, that is always present in any experimental result.
