SpaceX Falcon 9 Launches Starfall Demo

Starfall is SpaceX’s mass-produced reentry vehicle designed to autonomously transport valuable customer experiments and other payloads safely back from space to Earth, including for in-orbit manufacturing. Starfall is a cylindrical-shaped capsule approximately 0.75 meters tall with a diameter of 3.1 meters, weighing approximately 2,100 kilograms, and capable of carrying 1,000 kilograms of payload. It is designed to be carried on Starship flights.

The Physics of FTL Travel

Can humanity ever travel faster than light, or does every shortcut through spacetime break causality itself? We explore warp drives, wormholes, tachyons, and why the universe pushes back.

Merging Humans and AI: The Rise of Biological Computers

It’s no secret that tech companies are racing to build “artificial general intelligence,” or AI that can match a human brain without needing a lifeline. But our brains already do the same heavy lifting with just a fraction of the resources. Whether it’s energy, water, land, components, or, you know… money… human brains are just way cheaper. Right now, you can either buy a human brain cell-based computer… or rent time on a remote one. Yep, even brainpower’s got a subscription plan these days. So what can these living computers actually do? How do they work? And, most importantly, should we be freaking out a little bit?
