Quantum computers get a lot of attention, even though they are not ready for prime time, but quantum sensors are already ...

Here’s what you’ll learn when you read this story: Discovering a machine that could somehow produce thrust without releasing propellant would be a game-changer for human space travel. There’s just one ...

For decades, scientists have dismissed the idea of reactionless propulsion—the concept of generating thrust without expelling propellant—as a fantasy that defies the laws of physics. But Charles ...

At long last, a unified theory combining gravity with the other fundamental forces—electromagnetism and the strong and weak nuclear forces—is within reach. Bringing gravity into the fold has been the ...

This mission will pave the way for groundbreaking observations of everything from petroleum reserves to global supplies of fresh water. Researchers from NASA's Jet Propulsion Laboratory in Southern ...
