The 1st Law of Thermodynamics said that energy can not be created nor destroyed. But part of Einstein General Theory of Relativity (E=mc^2) said that energy can be created from matter. A one Kg matter contains enormous amount of energy.|||It is not a violation. You'd have no problem with "kinetic energy" or "potential energy" conversions, right? "Storage as mass" is just another form of potential energy. "Storage as rotational kinetic energy" as in a flywheel, "storage as flowing charge in a superconductor", "storage as vibrating molecules " (heat), and "storage as mass raised in a gravitational field" are other methods you might recognize.|||But matter is energy, you haven't destroyed nor created it. The amount of energy in the Universe is a constant.
At the big bang we had no mass only energy. Fundamental particles where then created from the energy. However we have lost no energy as energy and mass is the same thing.
Therefore no, it does not contradict.
All E=mc^2 says is that mass and energy is interchangeable.|||The equation doesn't say that energy can be CREATED from matter - it says that mass is just another form of energy. It says that mass and energy are equivalent quantities that are simply measured in different ways. They are two sides to the same coin.
