Sleep and ASMR by The French Whisperer

The silurian hypothesis is not a theory, but rather a thought experiment: what if a civilization had existed on Earth millions of years ago? After such a long time, could it have left any trace, taking into account the natural decay of all materials, sedimentation and plate tectonics? This video is not about an actual ancient civilization of which we have zero evidence. It is about how long the remains of a technically advanced civilization such as ours could last, and testify of our existence. This means looking into things such as the durabily of the materials we use and the things we build, the time it takes for our waste to disappear, geology, erosion... And also what kind of physical evidence of their existence different civilizations may leave behind them. Hosted by Simplecast, an AdsWizz company.

Let's go back to Prehistory tonight! Behavioral modernity is a concept created to describe a series of traits and behaviors that our species, Homo Sapiens, adopted over the past 100,000 years. The list of these traits, their timelines, their maps and the way archaeological records reflects them are still debated among paleontologists and paleoanthropologists. However, there is no doubt the phenomenon is real, and in this episode I tell you about the concept of behavioral modernity itself, its manifestations (burials, figurative art, long distance transportation of resources, better blades and tools...) and what could have triggered it.

In tonight's episode, I invite you to an overview of rooms, since humankind started to build homes. For much of our history, most people lived in single-room dwellings and multiple-room homes were a privilege for the happy few. This started to change after the 16th Century, and rooms multiplied for almost everyone, often influenced by aristocratic and bourgeois homes. From medieval long houses and manors, to aristocratic apartments, parlors or drawing rooms, to living rooms and modern bedrooms, we have a lot to discover! Hosted by Simplecast, an AdsWizz company.

What is this subjective experience, this awareness of existence, that we call consciousness? In tonight's episode, we will examine some of the aspects of this philosophical, scientific and spiritual question. Is consciousness a binary thing, or is it a kind of continuum with different "levels"? Do animals experience a degree of consciousness and how can it be infered of measured? Is it reductible to biology, is it the product of the treatment of information, is it something immaterial and detached from the physical world? Could an AI acquire consciousness from a silicon substrate, and if yes, what would be the pre-conditions and consequences? These are some of the questions we will try to answer, or at least understand better. Hosted by Simplecast, an AdsWizz company.

Our episode tonight takes us way back to 252 million years ago, at the end of the Permian geologic period. We will discover what marine life was like in the gigantic ocean called Panthalassa, as well as the flora and fauna of the supercontinent Pangea. In the last millions of years of the Permian, marine and land species began to go extinct in larger and larger numbers, culminating in the last million years in the most severe extinction event observed in the history of our planet. What are the possible causes of this extinction: volcanism, climate change, collision with a meteorite...? Hosted by Simplecast, an AdsWizz company.
