Jet engine output is measured in thrust, not horsepower. Thrust reflects the force moving an aircraft forward, making it the standard metric for jet power.

How, exactly, the laws of physics will crumble if NASA's impossible space engine turns out to really work.

Buhler made public his findings at the Alternative Propulsion Energy Conference, a meeting ground for engineers, scientists, ...

Near-infinite specific thrust from drive that ignores physics Conservation of momentum is for a different universe, apparently.

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.
