Einstein’s E = mc2 Stands the Tests of New Times

Albert Einstein’s most famous equation, expressing the relationship between mass and energy, passes the best tests of accuracy scientists have yet devised, according to a report in the journal Nature.

E = mc2 was confirmed in two tests, according to the report. Measured quantities of energy came within 0.00004% of the amounts predicted by Einstein. The energy in any object can be quantified by multiplying its mass by the square of the speed of light, according to the equation. The formula, part of the theory of special relativity that Einstein published in 1905, shows that matter and energy are equivalent.
