  • Mysteries of Consciousness

    Mysteries of Consciousness
    Nov 16 2025
    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.

  • Journey to the Permian Period - Sleep and ASMR

    Journey to the Permian Period - Sleep and ASMR
    Nov 12 2025
    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.

  • Ancient Lost Cities: Mycenae, Tenochtitlan (ASMR History for Sleep)

    Ancient Lost Cities: Mycenae, Tenochtitlan (ASMR History for Sleep)
    Nov 9 2025
    For tonight, I take you to two "lost" cities, because they were deserted or replaced with another one, but their stories are windows on chapters of human history. First we will go to Mycenae, a city-state and palace from the second millenium BC, that represents well the rise of Bronze Age palatial culture in Greece, long before the more familiar periods of Classical or Hellenistic Greece. Then we will move to Mesoamerica and discover the history of Tenochtitlan, the capital of the Aztec Empire. Tenochtitlan was a marvel of urban planning and engineering, built on an island on lake Texcoco, just where Mexico City now is. With around 200,000 inhabitants, it was one of the largest cities in the world in the 15th century, until its fall to the Spanish Conquest of Mexico. Hosted by Simplecast, an AdsWizz company.

But this was just a start: multiple conflicts saw him dominate Europe for a short time before a spectacular collapse. Hosted by Simplecast, an AdsWizz company.

  • What is the Multiverse? ASMR Bedtime Story for Sleep

    What is the Multiverse? ASMR Bedtime Story for Sleep
    Nov 1 2025
    This episode will give you an overview of the concept of multiverse: where does it come from? What are the various meanings and ideas behind that term? I will detail different versions of this idea, coming from cosmology (the "Eternal Inflation Multiverse" or the "Cosmic Landscape Hypothesis", derived from String Theory), quantum mechanics (the "Many-Worlds Interpretation"), or the "Computational Multiverse" hypothesis. I will also tell you about thinkers such as Anaximander, Copernic or Giordano Bruno, who all contributed in their own ways to the intellectual revolutions necessary for this concept to emerge.
