Is the search for the "cause" of the Big Bang a fundamental mistake? In this video, we explore the deep truths about time, causation, and the permanent limits of human knowledge. While we have solid evidence for the expansion of the universe and the Cosmic Microwave Background (CMB), we hit a "wall" when we try to look further back.

We explore:

The Observational Barriers: Why the Photon Barrier and the Planck Scale act as a permanent "No Entry" sign for science.

The Problem of Time: Why asking "what came before" might be as logically flawed as asking "what is north of the North Pole."

The Failure of General Relativity: How our equations break down into singularities and why Quantum Gravity might still not provide the "cause."

The No-Boundary Proposal: Stephen Hawking’s idea that the universe doesn't have a beginning in time.

Is the "Cause" of the Big Bang a category error? Join us as we explore the boundaries of scientific knowledge and accept the humbling truth about our cosmic origins.
