If a fact is proven wrong, it is said to have been disproven.
Yes, Einstein's theory of relativity was eventually accepted by the scientific community after experimental evidence supported its predictions. It revolutionized our understanding of space, time, and gravity.
Heinrich Hertz proved the existence of electromagnetic waves. The unit of frequency, hertz (Hz), is named in his honor.
A prediction that can be proved or disproved by experiments is that a chemical reaction will occur when two specific substances are mixed together under certain conditions. By conducting the experiment and observing the presence or absence of a reaction, the prediction can be verified.
Exactly what part about it is wrong? The mass-energy equivalence is widely accepted in modern physics. What is wrong is the popular explanation that "mass is converted to energy" in a nuclear reaction. In fact, both mass and energy are conserved in this case.
One part of Dalton's atomic theory that was proved incorrect is the assumption that atoms are indivisible and cannot be further subdivided. The discovery of subatomic particles such as protons, neutrons, and electrons showed that atoms are made up of smaller components.
If you're talking about the equation where 'e' is energy, 'm' is mass, and 'c' is the speed of light, then that one has never been proved wrong. In fact, it has predicted the correct results thousands of times.
