Partly to ensure that the dimensions of the equation balance.
E=mc2 E=energy m=mass c=speed of light Einstein's equation states that Energy equal mass times the speed of light squared
The energy (E) in any body of matter is equal to its mass (M) times the square of the speed of light (C2)
That equation is the equation that Albert Einstein came up with to describe how to calculate the speed of light. E = energy m = mass c = speed of light
Albert Einstein's most famous equation was probably E=MC2(Energy equals Matter times the (C) speed of light (186,000 miles per second).
This can be answered in two ways... If you're talking about Einstein's equation, then E=MC2. If you are wondering what E means, it stands for energy, so Einstein's equation means, "energy is equal to mass times the speed of light squared'.
Einstein used the equation E = hf to explain the photoelectric effect, where E is the energy of a photon, h is Planck's constant, and f is the frequency of the light. This equation shows that the energy of a photon is directly proportional to its frequency.
C represents a constant (the speed of light).
The equation E=mc^2 was developed by physicist Albert Einstein in 1905 as part of his theory of special relativity. It describes the equivalence of energy (E) and mass (m) and the constant speed of light (c) in a vacuum.
The fudge factor in the Einstein equation refers to the cosmological constant denoted by the symbol Λ, which Einstein originally introduced to achieve a static universe. The cosmological constant represents a repulsive force that counteracts gravity on cosmological scales, leading to the accelerated expansion of the universe in the current understanding of cosmology.
He hypothesized that the speed of light is constant, no matter what the frame of reference is.
The relation between the energy (E) of a photon and the frequency (v) of its associated electromagnetic wave is called the Planck relation or the Planck--Einstein equation:E = hvh is the Planck constant which as a value of about 6.626 * 10-34 J*s (a very very small number)

E=mc2 E=energy m=mass c=speed of light Einstein's equation states that Energy equal mass times the speed of light squared
The formula E=mc^2 describes the relationship between energy (E), mass (m), and the speed of light (c). It shows that energy and mass are interchangeable, with a constant factor being the square of the speed of light. It is a fundamental equation in physics, derived by Albert Einstein as part of his theory of relativity.
The energy (E) in any body of matter is equal to its mass (M) times the square of the speed of light (C2)
Albert Einstein proposed that the speed of light is constant in a vacuum and that light can behave as both a particle and a wave, known as wave-particle duality. He also introduced the theory of relativity, which revolutionized our understanding of time, space, and gravity.
Einstein first published his theory that E = mc2 in 1905. You forgot the = sign, which is pretty important, since the formula means that the energy of an object is equal to its mass times the square of the speed of light.
