The question of what happened before the Big Bang is one of the most fascinating and challenging mysteries in science. The Big Bang theory describes the universe's origin from an incredibly hot and dense state about 13.8 billion years ago, but it doesn't explain what, if anything, existed before this event. In fact, some scientists argue that the concept of "Before The Big Bang" might not even make sense because time and space as we understand them began with the Big Bang itself.
Several theories attempt to address this mystery. One idea is that our universe could have originated from a quantum fluctuation, suggesting it might be one of many universes in a larger multiverse. Another theory, the cyclic model, proposes that the universe goes through endless cycles of expansion and contraction, meaning the Big Bang could be just one phase in an eternal series of events.
While we don't have definitive answers, exploring these questions pushes the boundaries of our understanding of the cosmos. As our scientific knowledge and technologies advance, we may uncover more clues about the true nature of the universe and its origins.
