The Big Gang Theory is likely a misspelling of the Big Bang Theory. The Big Bang Theory proposes that the universe originated from a singular point of infinite temperature and density, roughly 13.8 billion years ago. This event marked the beginning of the expansion of the universe, resulting in the formation of galaxies, stars, and eventually the conditions necessary for life to develop. Over time, galaxies continue to move apart due to the expansion of space, leading to the continuous evolution of the universe as we know it today.
