Journey to the Center of the Earth, new issue of Mag Futura

In this new issue of Mag Futura, we wanted to introduce you to the mysteries and dangers of the depth. Because it is beneath our feet that the last unknown places remain. This paradox is regularly noted: we know the surface of celestial bodies millions of kilometers away from Earth better than the relief of our planet. twelve men stepped forward lunelune, while only four have dived to depths of more than 10,000 meters in the Mariana Trench. But scientific research is intended to bring these environments out of the shadows. Scan the depths of the world to study its many layers – and discover new ones! – Using more innovative methods (page 64). By diving deeper in search of treasures buried beneath the sediments, which are not always what we imagine (p. 106). By refining the mapping of the ocean floor to uncover the dangers lurking beneath our feet (page 70) (page 114). or by setting up observatories inside international waters, not without taking inspiration from our space Stationspace StationTo overcome our “gross ignorance” about deep sea life (p. 72).

The main thing is the discovery of fantastic species and a branch of life that has been forgotten by everyone, even our distant ancestors (p. 78)… But there are also new dangers, because the depths of the Earth hide happened MaterialMaterial Raw materials that arouse much desire, and scientists warn: some should not be dug up (page 80). Other underground resources also have potential that remains to be explored. We’ll also meet speleologists, modern-day explorers who encounter the underground world, “the real one.” windowswindows on the past”, whether geological, archaeological or biological (p. 92). Because they host vestigial biodiversity, authentic survivors.

Report / Diving in search of sunken treasure

As deep as Ali Baba’s cave but grander, there are many treasures in the seabed. Far from images of chests filled with gold coins, the submerged wrecks are filled with ordinary objects that tell the story of past lives. We set out on an exploration boat of the Department of Underwater and Underwater Archaeological Research (DRASAM) to meet the scientists who are trying to locate them to uncover their stories.

Key Interviews: Luc-Henri Fez and Stéphane Jellet “Underground environments are real windows to the past”

Among the last environments that humans have yet to explore, map and invest, the underground world is the playground – and research – of speleologists, a small community of enthusiasts eager for science and adventure. Among them, Luc-Henri Fages, explorer, amateur archaeologist and documentary film director, and Stéphane Jellet, research engineer at the CNRS, geomorphologist and expert in karst and caves. Meet these modern inventors. Interview conducted by Cassiopi Toscas.

Art and Science – Crazy Project. What if… we received a supernatural message?

If it was an alien life form that discovered us, and it sent us a message, how would we respond? How will we organize ourselves to decode and interpret it?
