Jan 26, 2017 · The theory is based on two fundamental principles: Relativity: The laws of physics do not change. Even for objects moving at inertial, constant speed frames of reference.
Sep 15, 2021 · E = mc² is a scalar equation because energy (E), mass (m), and the speed of light (c) all have only single, unique values. But Newton’s F = m a is not a single equation...

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.
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.
- What does Einstein’s equation actually mean?It shows that matter and energy are the same thing — as long as the matter travels at the speed of light squared. The latter is an enormous number...
- Why can't we travel at the speed of light?Einstein's theory predicts that when a mass of matter is multiplied by a square of light's speed, it gives off huge energy. However, for us to move...
- Is E=mc2 dimensionally correct?Yes. When mass and speed of light squared are multiplied, they give the same unit as that of energy – Joules. Thus, E=mc2 is dimensionally correct.
The theory of relativity usually encompasses two interrelated physics theories by Albert Einstein: special relativity and general relativity, proposed and published in 1905 and 1915, respectively. Special relativity applies to all physical phenomena in the absence of gravity.
