the claim

Mass-energy equivalence is expressed by E=mc^2.

the evidence backs this
Recorded sources
10 sources for · 0 against

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that mass-energy equivalence is expressed by E=mc^2?

Yes. A reference article on mass-energy equivalence states that mass and energy differ only by the speed of light squared, and a physics discussion explicitly cites the relation E=mc^2 with experimental evidence. Other items discuss mass-energy equivalence more generally without stating the formula.
