🌌 How We Discovered the Edge of the Universe (and What Lies Beyond)
Ever wondered how we went from believing the Earth was the center of everything to realizing the entire universe is expanding away from us?

In this episode, grab a cup of coffee and join the conversation as we trace the story of human cosmology. We go step-by-step through the major turning points in physics from ancient Greek astronomers observing lunar eclipses to Stephen Hawking’s mind-bending theories on black holes and quantum gravity.

If you love space, big questions, or just staring up at the night sky, sit back and enjoy the chat!

📌 WHAT WE COVER IN THIS EPISODE
• Ancient Astronomy: How Aristotle proved the Earth was spherical back in 340 B.C. using lunar eclipses, and how Ptolemy's Earth-centered model dominated for centuries.
• The Cosmic Shift: How Copernicus, Galileo, and Kepler overturned ancient cosmology with a sun-centered model, and how Isaac Newton explained universal gravity.
• The Expanding Universe: How Edwin Hubble observed galaxy red-shifts in 1929 and proved space itself is expanding.
• Black Holes & Quantum Radiation: Why collapsing stars exceed the Chandrasekhar limit
and how quantum particles leak out as Hawking radiation.
• The No-Boundary Condition: Hawking and Jim Hartle's proposal using imaginary time, picturing a universe that is finite without an edge or starting singularity.
• The Theory of Everything: What it actually takes to unite quantum mechanics with general relativity into a single framework.
