Overview
Special relativity, introduced by Albert Einstein in 1905, revolutionized our understanding of space and time. The theory postulates that the laws of physics are the same for all observers in uniform motion relative to one another.
Derivation of E=mc²
The equation E=mc² was derived by Einstein in 1905, as a consequence of special relativity. It states that energy (E) is equal to mass (m) times the speed of light (c) squared. This equation shows that mass and energy are interchangeable, and that a small amount of mass can be converted into a large amount of energy.
Implications of E=mc²
The implications of E=mc² are far-reaching. It explains the energy released in nuclear reactions, such as those that occur in the sun and in nuclear power plants. It also has implications for our understanding of the universe, including the formation of black holes and the expansion of the universe itself.
Experimental Evidence
Experimental evidence has consistently confirmed the predictions of special relativity and E=mc². Numerous experiments have demonstrated the equivalence of mass and energy, and the speed of light has been measured with increasing precision over the years.
