However, many scientists question the reality of singularities, arguing they are mathematical artifacts rather than physical realities. Instead, some models suggest that collapsing matter reaches an extreme density but then undergoes a bounce, transforming the collapse into a rapid expansion—an event remarkably similar to our Big Bang. This process avoids the problematic infinite density and, intriguing enough, its calculations match the famous period of rapid expansion known as cosmic inflation.
