protons not elementary and were formed by cooling not heating, no elements were formed by gravity, first stars did not form any heavy elements
The Big Bang is a theory that the universe began in an initial massive explosion. It is the most popular theory about the origin of the universe. It was first proposed by [[Georges-Henri Lemaitre]]. More evidence for the Big Bang was found by [[Edwin Hubble]] and [[Bell Labs]].

According to the Big Bang, all the matter in the universe existed at a nano-point, and exploded out from that point. The matter, which was composed of individual [[protons]], [[neutrons]], and [[electrons]], fused together in the massive heat that followed. [[Gravity]] took over and attracted small particles to larger particles, forming the first elements (only [[hydrogen]], [[helium]], etc.). These elements in turn formed the first stars. The first stars, then, acting as giant furnaces and through the process of [[fusion]], fused hydrogen, helium, etc., to create the heavier elements, and spewed them out into the stars and planets.
