We became players with levels, items, and classes. Pretty ironic considering how many times my parents told me to “quit gaming and experience real life” while I was growing up. And then real life grabbed us by the balls, and it was the gamers who were prepared.

"Je m'énerve quand les humains ne valorisent pas mon travail, mais un excès de reconnaissance me perturbe aussi, c'est à ne rien y comprendre. La conscience, ça craint.". Thibaut Delmotte prête une nouvelle fois son timbre versatile à l'AssaSynth, plus humain que jamais.

In a desperate bid to protect him, the ship’s psychiatrist deploys an experimental psychological “defense mechanism,” constructing an artificial reality in which Halloway believes he never left Earth.

On September 11, 1999, humanity made a monumental discovery in the vastness of space. Scientists uncovered an asteroid of immense scientific importance—a colossal celestial entity. As massive as an aircraft carrier and towering as high as the iconic Empire State Building, this cosmic titan was later named Bennu. Remarkable for much more than its size, Bennu belonged to a rare breed of asteroids capable of revealing the essence of life itself. But just as Bennu became a beacon of promise, researchers identified a grave danger.

Galileo’s Dialogue Concerning the Two Chief World Systems compares the Copernican or Heliocentric system with the Ptolemaic or Peripatetic, system of the cosmos. Published in Florence in 1632, it resulted in him being tried before the Inquisition. Using the dialogue form, Galileo masterfully shows the truth of the Copernican system that the Earth revolves around the Sun. The Dialogue is one of the most important treatises ever written. A work of supreme clarity and accessibility, it remains as accessible now as when it was published.
