can any one explain what does E=MC2 means ?????????????
E = mc2 is the energy-mass equivalence relation and is probably the most famous formula in physics. It simply means that the two physical quantities energy and mass are related to each other and are equivalent. In other words, mass means energy and energy means mass. Here 'c' is a constant which represents the speed of light.
This is the main idea behind the working of the atomic bomb.
