Most astronomers use the Big Bang theory to explain how the universe began. But what caused this explosion in the first place is still a mystery. The Big Bang event is a physical theory that describes how the universe expanded from an initial state of high density and temperature. Various cosmological models of the Big Bang explain the evolution of the observable universe from the earliest known periods through its subsequent large-scale form. These models offer a comprehensive explanation for a broad range of observ… WebThe Big Bang was the earliest known event in the universe. We can trace the history of our universe back about 14 billion years, to a fiery period known as the Big Bang. At that time, the universe was extremely hot and dense.
