The Greatest Cosmic Mystery
For nearly a century, the Big Bang theory has stood as the predominant explanation for the origin of our universe. But as our observational capabilities grow and theoretical physics advances, scientists are increasingly examining both the strengths of this paradigm and the fascinating alternatives that challenge our understanding of cosmic beginnings...
I. The Big Bang Theory: Foundation of Modern Cosmology
1.1 The Birth of a Cosmic Paradigm
The story of the Big Bang theory begins in the early 20th century with key discoveries:
- Einstein's General Relativity (1915)
- Edwin Hubble's expanding universe observations (1929)
- Georges Lemaître's "primeval atom" hypothesis (1927)
"The Big Bang theory represents our best current understanding of universal origins, supported by multiple lines of evidence." - Dr. Brian Greene
1.2 Pillars of Evidence
The Big Bang rests on four foundational proofs:
