Answer:
It must be verified by scientists around the world.
Explanation:
A theory is a rational and plausible explanation of a certain phenomenon that occurs in the universe and that can be explained scientifically.
The theory is formulated after certain experiments have been done, however, it is not considered an absolute truth, as it can be motivated through the years by other experiments and with the advancement of technology. In that case, a theory can be refuted and reframed as new evidence is discovered. In addition, in order for it to remain relevant, it must be supported by many scientific investigations over time, until the moment comes when the experiments comprised 100% of this theory, allowing it to start being called "Scientific Law". However, it is not necessary for all scientists in the world to test the theory in their experiments.
