Key Takeaways

  • Prehistoric astronomy origins: A 17,000-year-old baboon bone carved with 29 notches likely represents the first lunar calendar, tracking the moon's 29.5-day cycle, suggesting women were humanity's first astronomers and mathematicians through observing menstrual-lunar connections.
  • Birth of scientific method: Astronomy midwifed modern science by providing the first domain where quantitative measurements of regular phenomena enabled hypothesis testing. Tycho Brahe's precise planetary observations forced theories to match observational accuracy, establishing experimental verification as fundamental.
  • Distance measurement breakthrough: The 1769 James Cook expedition to Tahiti measured Venus transiting the sun from multiple Earth locations, calculating the Earth-Sun distance at 150 million kilometers. This stepping stone enabled Newton to estimate Sirius sits one million times farther than our sun.
  • Cepheid variable discovery: Henrietta Swan Leavitt's law in the 1900s identified stars whose flashing frequency reveals intrinsic brightness. Using inverse square law calculations, Edwin Hubble measured these variables to prove galaxies exist beyond the Milky Way and the universe expands continuously.

What It Covers

Cosmologist Roberto Trotta explores how observing stars shaped human civilization, from prehistoric lunar calendars to modern science, and imagines how different our world would be without access to the night sky.

Notable Moment

Trotta argues Neanderthals possessed equal intelligence to Homo sapiens but lacked star-driven curiosity that enabled navigation, timekeeping, and abstract thinking. This astronomical disadvantage may explain why they disappeared while our ancestors developed technology and survived for 800,000 years.

But if you're in The UK, the full series is available right now, first on BBC Sound. Hello. I'm Brian Cox. I'm Robin Ince. And this is the Infinite Monkey Cage. Today, we ask a big question. What if there existed a universe that was without Patrick Moore or indeed Brian Cox? What if it was a cosmos without the sky at night? Because there was no sky at night, just an inky blackness. The experience of standing alone on a clear night and looking at the stars, of dreaming of worlds beyond our own, worlds beyond imagination, is not only a powerful emotional experience, but also a powerful intellectual one. The attempt to understand the motion of those points of light in the dark was key to the development of modern science. And it is something it's something we talked about a lot when we were on tour, that beauty that when you you go out on a clear night and you look at those stars and you think about those photons where basically they've been created from hydrogen becoming helium. The photons then travel across distances far greater than we can currently imagine ever traveling ourselves. And then the first thing that they actually collide with is us, something that is able to think of what has happened, think about …
