The sun produces energy via nuclear fusion—that is, it fuses two atoms into one, releasing a tremendous amount of energy in the process. The most common form of fusion in the sun is when hydrogen atoms are fused into helium—giving off energy in the process due to the lost mass. This is the most efficient […] Continue reading

Like other electromagnetic particles, light has a specific velocity at which it travels. Further, it is presumed to be the fastest theoretical speed of any particle. The speed of light–referred to as “c” in a vacuum–is roughly 300,000,000 m/s. Since it moves so fast, most people never observe light as a moving particle or something […] Continue reading
