Part 5/9:
The conversation shifts to the trajectory of cosmological theories, particularly those emerging from Einstein’s groundbreaking work in general relativity, which rocked the foundations of classical physics. His equations, while complex and nonlinear, hint at a universe that is not static but dynamic—constantly expanding from an initial singularity, approximately 15 billion years ago. This fundamental shift contradicts a static, everlasting universe and introduces the idea of a universe birthed from nothingness.
