According to the patent, habitable modules would rotate around a central axis to simulate gravity for crew by producing an outward-pushing centrifugal force. When you purchase through links on our ...

Across social media, inversion tables, devices that tilt users upside down or at an angle, are being touted as a "magic solution" for everything from back pain to age reversal. The most recent person ...

This isn’t your average furniture project. With a clever hidden structure and mind-bending visuals, the floating cave table seems to defy physics. It’s part sculpture, part illusion, all skill... ‘Not ...

A new argument explores how the growth of disorder could cause massive objects to move toward one another. Physicists are both interested and skeptical. Isaac Newton was never entirely happy with his ...

A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum world. However, the new theory remains far from being proven observationally.

We have long taken it for granted that gravity is one of the basic forces of nature—one of the invisible threads that keeps the universe stitched together. But suppose that this is not true. Suppose ...

This month we feature chemicals that have important applications in industry and the lab.—Ed. H 2 SO 4 has a wide range of uses. Most of it (≈60%) is consumed in extracting phosphoric acid from ...

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 ...

All the fundamental forces are thought to be carried by a particle, but a new mathematical model suggests gravity may be a striking exception. Building on a decades-old idea, researchers have revealed ...
