The Big Bang theory is a widely accepted scientific explanation for the origin and early development of the universe. While it can be a complex concept to understand fully, it is not considered preposterous within the scientific community. The theory is supported by a substantial body of evidence, including cosmic microwave background radiation, the abundance of light elements, and the observed expansion of the universe.
It's important to note that the Big Bang theory does not suggest that all galaxies, planets, and stars were initially compressed into a single point. Rather, it proposes that the universe began from an extremely hot and dense state and has been expanding and evolving ever since. In the early stages, the universe was in a highly energetic and compact state. As it expanded, matter and energy began to cool and form structures such as galaxies, stars, and planets over billions of years.
The universe is vast, and the distribution of galaxies and celestial objects is not a matter of everything being crammed into a single point. Instead, galaxies and other structures formed and continue to evolve through gravitational interactions and other astrophysical processes. The current understanding of the universe suggests that it is characterized by large-scale structures like galaxy clusters and superclusters, with vast expanses of empty space in between.
Scientific theories, including the Big Bang theory, are continually subject to scrutiny, refinement, and revision as new evidence and observations emerge. However, as of now, the Big Bang theory remains the leading explanation for the origin and evolution of the universe, supported by a wide range of observational data.
