The Big Bang
The Big Bang theory is the prevailing cosmological model describing the origin and evolution of the universe. According to this theory, the universe originated from a singular point around 13.8 billion years ago, rapidly expanding and cooling over time. This event marked the beginning of space, time, and all matter and energy in the cosmos. The Big Bang theory is supported by various lines of evidence, including the cosmic microwave background radiation and the observed expansion of the universe. It provides a framework for understanding the universe's structure, composition, and development from its earliest moments to the present day.
