Ancient Rocks and Cosmic Forces: Exploring Earth's Origins and the Hunt for a Fifth Force
Episode 136
Wednesday, 19 November, 2025
In this episode of SpaceTime, we delve into remarkable discoveries that illuminate the origins of our planet and the cosmos beyond.Ancient Australian Rocks Shed Light on Earth's OriginsScientists have made significant strides in understanding the formation of Earth and the Moon through the analysis of 3.7 billion-year-old feldspar crystals from the Murchison region in Western Australia. This research reveals that continental growth began relatively late in Earth's history, around three and a half billion years ago, suggesting a shared composition between Earth and the Moon following a colossal impact event. The findings challenge existing theories about the timing of crustal development and provide new insights into the early geological processes that shaped our planet.Hints of a Possible Fifth Force in NatureA groundbreaking report has emerged, suggesting the potential existence of a fifth fundamental force of nature. Researchers have observed unexpected deviations in electron transitions among calcium isotopes, hinting at a new particle, the Yukawa boson. This discovery could reshape the standard model of particle physics and deepen our understanding of the universe's fundamental forces, as scientists continue to explore the mysteries of atomic interactions.Record-Breaking Ocean Waves Observed from SpaceIn an astonishing revelation, satellites have recorded ocean waves reaching heights of nearly 20 metres, the largest ever measured from space. This episode explores how these massive waves, driven by storms, can carry destructive energy across vast distances, impacting coastlines far from the storm's origin. The findings not only validate existing wave models but also reveal new insights into the energy dynamics of ocean swells.www.spacetimewithstuartgary.com✍️ Episode ReferencesNature CommunicationsPhysical Review LettersProceedings of the National Academy of SciencesBecome a supporter of this podcast: https://www.spreaker.com/podcast/spacetime-your-guide-to-space-astronomy--2458531/support.
