Lecture 3b: Ancient Cosmologies and the Origin of Time

Hello everyone, and welcome back to the channel. In this lecture, we apply the forensic tools we established last week to look at the absolute first clues our ancient ancestors left behind in the night sky. We travel back 15,000 years into deep human history—long before writing, cities, or agriculture existed—to see how stargazing was born out of pure survival. When our hunter-gatherer ancestors looked up into a dark sky free of modern light pollution, they picked up two massive, unignorable patterns. The first was a completely fixed, unchanging background of stars. The second was a group of exactly 7 unique lights that broke the rules and wandered independently against those stars. In this video, we explore how tracking the Sun gave humanity its baseline unit of a single Day, while tracking the 29.5-day cycle of the Moon gave birth to the concept of a Month. We look at the actual archaeological evidence—sequences of 29 and 30 scratches carved into prehistoric animal bones—proving that hunter-gatherers mapped the lunar cycle thousands of years before civilization began. About Me: My name is Muaz, and I am a graduate Astrophysics student at LMU Munich (The University of Munich) in Germany. My current research and master's thesis specialize in the Hubble Tension, one of the most active observational crises in modern cosmology today. What You Will Learn in This Video: 1. Pattern Seeking: How hunter-gatherers mapped the night sky. 2. Fixed Stars vs. The 7 Wanderers. 3. Why Uranus and Neptune required modern telescopic breakthroughs. 4. The Survival Physics of the Sun: Mapping days and shifting seasonal paths. 5. Lunar Tally Marks: The 29.5-day cycle and the origin of the "Moonth."

Share this video with students, or space enthusiasts who want to learn how the machinery of science truly functions. Thank you for watching! In our next episode, we leave natural astronomical cycles behind to uncover a shocking truth: the 7-day week is a completely artificial human invention. See you next Saturday at 6:00 PM PKT (3:00 PM Munich time)! #AncientHistory #Cosmology #Astrophysics #LMUMunich #TheIntelligibleUniverse #PhysicsLectures #Stargazing #HistoryOfScience #Astronomy #HubbleTension
