The Sun

About this episode

What if everything you thought you knew about sunlight was just scratching the surface? ☀️🔬

In this illuminating episode of Sunlight Matters, hosts Dave and Georg sit down with world-renowned astrophysicist Dr. Bob Fosbury — a former senior scientist with the European Space Agency, key contributor to both the Hubble and James Webb Space Telescopes 🔭, and a trailblazer at the intersection of astronomy, biology, and human health.

🌌 From black holes and the Big Bang to mitochondria and macular degeneration, Bob connects the dots between cosmic light and cellular life in a way that’s as profound as it is practical. This is not just science — this is a blueprint for how to live in harmony with the energy source that powers everything on Earth: the Sun. 

🎙️ Together we explore how infrared light, once overlooked, is now recognized as vital for metabolism, ageing, mitochondrial health, and even mental clarity. You’ll understand why modern architecture, LED lighting, and indoor living might be depriving us of essential solar wavelengths — and what steps we can take to reconnect with full-spectrum sunlight in our homes, cities, and everyday lives. 

☀️ In This Wide-Ranging Episode, We Cover:

• 🌌 The origins of light — and how it shaped the universe
• 🌱 How photosynthesis and metabolism mirror the thermodynamics of stars
• 🧬 The role of infrared light in mitochondrial function and ATP production
• 🚨 Why white LED lights may be disrupting human biology and increasing disease risk
• 🏢 How urban planning, window glass, and building design limit natural solar exposure
• 🧠 How entropy, aging, and light are intimately connected
• 🧭 Why understanding the energy flow of life can help us build healthier, more sustainable systems
• 🌞 The future of sunlight-based health interventions, lighting design, and planetary living

Whether you're a curious mind, an architect, a real estate professional, a health practitioner, or someone exploring the science of sunlight for personal vitality, this episode offers new frameworks, ancient truths, and practical insights. You’ll never view the Sun (or your indoor lights) the same way again.
