Answer:
Einstein's equation E=mc^2 demonstrated the unity between mass (m) and energy (E). This equation expresses the concept of mass-energy equivalence, showing that mass and energy are not separate entities but are interconvertible. In other words, it demonstrates that there is a direct and fundamental relationship between the amount of energy (E) that an object possesses and its mass (m).
The "c" in the equation represents the speed of light in a vacuum, which is a very large constant. This equation essentially states that a small amount of mass can be converted into a large amount of energy and vice versa, as long as you account for the speed of light. It was this groundbreaking idea that revolutionized our understanding of the unity between mass and energy and laid the foundation for modern physics.
