Mass-Energy Equivalence: Understanding E = mc²

Einstein’s equation 𝐸=𝑚𝑐² shows mass and energy are two forms of the same thing.
Even tiny amounts of mass contain enormous energy because 𝑐² is huge.
This principle powers the Sun, where mass is converted into energy through nuclear fusion.
Nuclear power plants and atomic bombs both rely on mass-energy equivalence.
When particles and antiparticles meet, their mass fully converts into energy.
Energy can also create mass—high-energy collisions in accelerators produce new particles.
The equation unites matter and energy into a single concept in physics.
It explains why stars shine for billions of years by steadily turning mass into light.
Mass-energy equivalence helps scientists probe the origins of the universe.
𝐸=𝑚𝑐² remains one of the most famous and revolutionary equations in science.
