The formula demonstrates that mass and energy can be exchanged, provided that the conversion factor (c²), which is the speed of light squared, is used.

How Einstein Formed This Formula?

The formula was originally written by Einstein as m= L/ c², where "L" stands for Lagrangian, a general representation of energy. Later, he replaced "L" with "E," and after modifying the variables, the equation took its famous form, E=m c².

Theory Of Relativity

The equation E=MC2 is a consequence of Einstein's Special Theory of Relativity, which he presented in 1905.

Speed Of Light

In this equation, "c" represents the speed of light, which is approximately 299,792 kilometres per second (186,282 miles per second) in a vacuum.

What E=mc² Means?

The equation E=mc² states that energy and mass are equivalent. This effectively means that a large amount of energy can be created from a little amount of mass and vice versa.

Space and Time

Einstein first proposed the idea that mass and energy are interchangeable through his theory of special relativity, highlighting their deep connection as a universal concept arising from the symmetry of space and time. The theory of special relativity unifies space and time into a single four-dimensional continuum called spacetime.

According to the principle of mass-energy equivalency, even in stationary states, all mass-containing things, or massive objects, have a corresponding intrinsic energy.
