General relativity, also known as the general theory of relativity and Einstein's theory of gravity, is the geometric theory of gravitation published by Albert Einstein in 1915 and is the current description of gravitation in modern physics.
Special relativity revealed that the speed of light is a limit that can be approached but not reached by any material object; it is the origin of the most famous equation in science, E = mc2; and it has led to other tantalizing outcomes, such as the “ twin paradox .”
E=mc^2 - The Equation Explained with Worked Examples. The purpose of these pages is to explain E = mc 2 in a clear, concise and understandable way with easily followed worked examples, and with further pages examining the Special Theory of Relativity in order to describe its background.
Apr 5, 2014 · It says that the energy (E) in a system (an atom, a person, the solar system) is equal to its total mass (m) multiplied by the square of the speed of light (c, equal to 186,000 miles per second).
Einstein went on to present his findings mathematically: energy (E) equals mass (m) times the speed of light (c) squared ( 2 ), or E=mc 2. The secret the equation revealed—that mass and energy are different forms of the same thing—had eluded scientists for centuries.
In Einstein’s corrected formula $m$ has the value \begin {equation} \label {Eq:I:15:1} m=\frac {m_0} {\sqrt {1-v^2/c^2}}, \end {equation} where the “rest mass” $m_0$ represents the mass of a body that is not moving and $c$ is the speed of light, which is about $3\times10^5$ $\text {km}\cdot\text {sec}^ {-1}$ or about $186 {,}000$ $\text {mi}\cdo...
Sep 19, 2023 · Albert Einstein formulated E=mc² in 1905 as part of his special theory of relativity. He first published a paper in June of that year about the properties of light and time. A few months later, he had reached a new conclusion, which gave us the equation.
