The Big Bang Theory: A Cosmic Beginning or a Story of Eternal Fluctuations?

Exploring the Origins of the Universe

The Big Bang Hypothesis

The Big Bang theory is a well-established scientific model describing the birth of the universe. It posits that approximately 13.8 billion years ago, the universe emerged from a singularity, an infinitely dense and hot point, and has been expanding ever since. This theory accounts for the observed expansion of the universe and the cosmic microwave background radiation, a remnant of the early universe's intense heat.

However, the Big Bang theory has its limitations. While it provides insights into the universe's origins, it does not fully address the question of what existed before the singularity. This has led to alternative theories, such as the Oscillating Universe Theory.

The Oscillating Universe Theory

The Oscillating Universe Theory proposes a cyclical view of the universe's evolution. According to this theory, our universe is just one in a series of endless cycles of birth, expansion, collapse, and rebirth. The Big Bang event, in this scenario, is not the beginning of the universe but rather the end of a previous cycle and the trigger for a new one.

There is some evidence to support the Oscillating Universe Theory. For example, cosmic microwave background radiation has been found to be slightly polarized, suggesting that the universe may have experienced an earlier contraction phase before expanding novamente.
