relativistic energy

Relativistic energy, a concept from Albert Einstein's special theory of relativity, describes the energy of objects moving at speeds close to the speed of light (c). It is fundamentally linked to an object's mass through the famous equation (E = mc^2). This equation signifies that mass and energy are interchangeable.1

Key aspects include:
* Relativistic Mass: An object's mass increases as its speed approaches the speed of light, requiring infinite energy to reach that speed.23
* Mass-Energy Equivalence: The equation (E = mc^2) shows that mass can be converted into energy and vice versa. This principle is crucial in understanding nuclear processes like fission and fusion, as well as phenomena in particle physics and astrophysics.45
