Mass-energy equivalence is a principle in physics that suggests that mass and energy are interchangeable, and they are two forms of the same entity. This concept is famously encapsulated in Albert Einstein's equation: \\\[ E = mc^2 \\\] In this equation: - \\( E \\) is the energy, - \\( m \\) is the mass, - \\( c \\) is the speed of light in a vacuum (approximately \\( 3 \\times 10^8 \\) meters per second).
