Theia’s Legacy: How a Cosmic Collision Shaped the Earth and the Moon

In this episode, MrEarthGuy talks about a brand new research paper which highlights the uncanny similarities between Venus and Earth. From mountains and volcanoes, to plateaus and mantle plumes, we may be getting one step closer to understanding our own history by looking to our twin - Venus!

In this episode, MrEarthGuy discusses the various factors that go into mountain building and why there is a theoretical limit to how tall they can grow here on our planet.

Join us on a captivating scientific adventure as we explore the mysterious depths of hydrothermal vents! These undersea chimneys, once thought barren wastelands, might hold the key to life's origins. Unravel the story of how scientists recreated ancient vent conditions to generate fatty acids - essential building blocks of life - from scratch! Discover how these vents acted as a primordial kitchen, potentially brewing the ingredients for life billions of years ago. Beyond Earth, explore the exciting possibility that similar processes could be occurring on distant icy moons like Enceladus and Europa. Could life be brewing in the depths of our solar system? This episode dives deep into the fascinating world of hydrothermal vents, challenging traditional theories and unveiling the potential for extraterrestrial life. Join the quest to understand where we came from and where life might exist beyond our planet!

In this episode, we explore the fascinating world of insects and how they respond to changes in atmospheric oxygen. We talk to Dr. John VandenBrooks, a researcher who raised different kinds of insects in various oxygen levels and discovered some surprising results. We also discuss the implications of his findings for understanding the evolution of giant dragonflies and other ancient insects, as well as the potential of using fossilized insects as proxies for paleo-oxygen levels. Join us as we dive into the breath of bugs and learn how oxygen shapes insect evolution.

Join MrEarthGuy as he reveals the secrets and mysteries of the Earth and the Moon, and how they were formed by a violent collision between two ancient planets. Learn how the remnants of the impactor, Theia, still lie deep within the Earth, and how they influence its evolution and dynamics. Discover how the Moon was created from the debris of the collision, and why it has a different composition than the Earth. Explore the latest scientific findings and theories, as well as the stories and legends that have shaped our understanding of the Earth and the Moon. This is Theia’s Legacy, a podcast that uncovers the hidden history of our planet and its moon.

In this episode of Earth SciShow, MrEarthGuy explores the fascinating world of ancient diamonds, the rare and precious gems that can reveal the history of continents and life on Earth. We follow the journey of these diamonds from their formation deep in the mantle, to their eruption on the surface, to their discovery in mines across different continents. We learn how these diamonds were formed from a mixture of subducted oceanic crust and mantle material, and how they were carried by plumes of hot rock to the base of Gondwana, a supercontinent that once covered most of the southern hemisphere. We also learn how these diamonds helped Gondwana to resist subduction and to remain stable for hundreds of millions of years, during which it experienced dramatic climatic and environmental changes, and witnessed the emergence and diversification of complex life forms. Finally, we learn how these diamonds were scattered across the globe when Gondwana broke apart, opening new oceans and creating new continents. These ancient diamonds are Earth’s wonders, and they can tell us a lot about how our planet works and how it has changed over time.

In this episode of Earth SciShow, MrEarthGuy discusses the difficult question on when the first animals evolved on Earth. Is there a way for us to narrow down the time period and isolate a moment beyond which no animals existed? Please subscribe and leave a review if you enjoyed the episode!

In this episode, we explore the amazing discovery of glass shards from the Taupō eruption in Antarctica, and how they reveal the global impact of this ancient volcanic event on the climate and history. We also learn how scientists used ice cores and radiocarbon dating to confirm the timing and source of the eruption. Join us as we journey back in time to witness one of nature’s most powerful and mysterious forces. 

In this episode of Earth SciShow, MrEarthGuy unveils a hidden new process within the global carbon cycle. Called Organic Carbon weathering or OCPetro for short, this new process has brought to light a brand new factor in the natural climatic processes in the Carbon Cycle. Are we passed the point of no return for climate change? or can Earth's natural processes support the rapid changes in climatic carbon.

In this episode of Earth SciShow, MrEarthGuy explains how the water on Earth is older than the planet itself. Through some keen observations in early solar systems and lab experiments on Earth, we can show that water was once floating around the cosmos before becoming fused with the protoplanets that became planets today.
