      The equation E = mc², formulated by Albert Einstein, expresses the relationship between energy (E), mass (m), and the speed of light (c) in a vacuum.

      Here’s what it means:

      E stands for energy,

      m is mass,

      c is the speed of light (approximately 299,792,458 meters per second),

      c² means the speed of light squared.

      This equation tells us that mass and energy are interchangeable—they are different forms of the same thing. A small amount of mass can be converted into a tremendous amount of energy because the speed of light squared (c²) is a huge number. This principle is the basis for nuclear energy and atomic bombs, where tiny amounts of mass are converted into vast energy releases

      Hey! 👋
      E = mc² means energy (E) equals mass (m) times the speed of light (c) squared.

      It shows that mass can be converted into energy, and even a small amount of mass gives a huge amount of energy because c² is very large. 💥
