Well, according to E=MC2
Mass is the same as energy divided by the speed of light squared.
But currently no, mass cannot be created.
The downward force created by a mass is equal to the mass multiplied by the acceleration due to gravity. This force is known as weight and it acts in the opposite direction of the gravitational pull.
According to the principle of mass-energy equivalence (E=mc^2), energy and mass are interchangeable. In theory, energy can be created without mass, such as in the case of virtual particles popping in and out of existence in quantum mechanics. These particles have energy but no permanent mass.
The force created on a mass of 50kg is equal to the mass multiplied by the acceleration due to gravity. On Earth, this force is approximately 490 Newtons (50kg * 9.81 m/s^2).
Conservation of mass... but this has been slightly revised since. Now it is the conservation of energy. Mass can be converted to energy. In some chemical reactions in the early 20th century scientists observed that the mass of the reactants did not equal the mass of the products. This was ultimately resolved with Einstein's mass-energy equivalence formula, E = mc^2, where Eistein postulated that some rest mass was converted to energy. From this, we know that energy cannot be created or destroyed.
According to the law of conservation of mass, mass cannot be created or destroyed in a chemical reaction. Similarly, according to the law of conservation of matter, matter cannot be created or destroyed in a closed system. These laws demonstrate that mass and matter remain constant throughout physical or chemical changes.
