Scientists have been searching for the origin of some of the most precious metals on Earth – including gold, silver, and platinum – for almost six decades. And now we might finally have the answer.
“Wormholes” are cosmic tunnels that can connect two distant regions of the universe, and have been popularized by the dissemination of theoretical physics and by works of science fiction like Stargate, Star Trek or, more recently, Interstellar. Using present-day technology it would be impossible to create a gravitational wormhole, as the field would have to be manipulated with huge amounts of gravitational energy, which no one yet knows how to generate. In electromagnetism, however, advances in metamaterials and invisibility have allowed researchers to put forward several designs to achieve this.
Exceeding speeds of 760 miles per hour, supersonic jets pierce the sound barrier with a resounding “BOOM!”
Every action creates an equal and opposite reaction. It’s perhaps the best known law of physics, and Guido Fetta thinks he’s found a way around it.
