E = mc2, equation in German-born physicist Albert Einstein's theory of special relativity that expresses the fact that mass and energy are the same physical entity and can be changed into each other.
There is ample experimental evidence that it (mass) is actually a function of the velocity of the body, increasing with increasing velocity according to the relation m = m/(1.
Mass-energy equivalence entails that the total mass of a system may change, although the total energy and momentum remain constant; for example, the collision of an electron and a proton annihilates the mass of both particles, but creates energy in the form of photons.
Albert Einstein's mass-energy equation E=mc2 is inadequate and valid only under certain conditions, with a proper study not carried out, an Indian researcher claimed recently. The famous equation, revealed by Einstein in 1905, means energy is equal to mass multiplied by the speed of light squared.Jan 13, 2016
Light has no mass so it also has no energy according to Einstein, but how can sunlight warm the earth without energy? Light indeed carries energy via its momentum despite having no mass.Apr 1, 2014
The energy of a particle diverges to infinity as it approaches the speed of light. Since we can never have infinite energy for a particle, the speed of light cannot be reached. Since an object has infinite kinetic energy when it approaches the speed of light, it therefore has infinite mass as well.
Derivation of Einstein's Equation The simplest method to derive Einstein's mass-energy equation is as follows, Consider an object moving at a speed approximately of the speed of light. A uniform force is acting on it. Due to the applied force, energy and momentum are induced in it.
This equivalence of mass and energy is a consequence of Einstein's theory of special relativity. Which simply means that mass can be converted into energy and visa-versa.
Einstein's Mass-Energy equivalence Einstein gave mass-energy equivalence relation as: - E=mc2. Any object which has got mass 'm' has mass energy associated with it and it is given as mc2. This relation helps in understanding nuclear masses and interaction of nuclei with each other.
In Summary: Yes, time travel is indeed a real thing. But it's not quite what you've probably seen in the movies. Under certain conditions, it is possible to experience time passing at a different rate than 1 second per second.Apr 30, 2020

E = mc2 Explained. E = mc2. It's the world's most famous equation, but what does it really mean? "Energy equals mass times the speed of light squared." On the most basic level, the equation says that energy and mass (matter) are interchangeable; they are different forms of the same thing.
