More than half a century ago, Sir Roger Penrose envisioned a scenario in which energy could be extracted from a black hole ...

Quantum physics tells us about the properties and behaviors of atomic and subatomic particles. But scientists have long held the belief that the rules that govern the microscopic world should also be ...

Analog machine learning hardware offers a promising alternative to digital counterparts as a more energy efficient and faster platform. Wave physics based on acoustics and optics is a natural ...

We just turned the volume up on the sky. Gravitational waves, the booming echoes of massive objects moving all over the universe, have been detected for the first time by LIGO, the Laser ...

Taken from the October 2018 issue of Physics World, which celebrates 30 years of the world’s best physics magazine. James Hough outlines the last 30 years of gravitational-wave astronomy, from ...

Where the information comes from: In the experimental part of the work, the researchers placed Teflon objects (orange cylinders) in a waveguide with a rectangular cross-section. They then injected an ...
