Ripples in the fabric of space-time could reveal how the universe was created nearly 14 billion years ago. But finding these ripples, known as 'gravitational waves', has so far proved elusive. Now, US ...

Imagine standing by a lake and throwing a stone into the water. Waves spread out in circular patterns and can reflect at obstacles and boundaries. Researchers at the University of Regensburg, in ...

While the concept of time travel has long captured public imagination, modern physics actually approaches time in a much more ...

A ripple tank can be used to measure and calculate frequency, wavelength and the speed of waves on the water's surface. A ripple tank is a transparent shallow tray of water with a light shining down ...

Heat is not supposed to behave like this. In everyday life, warmth seeps and diffuses, spreading from hot to cold in a slow, smearing process that never looks anything like a crisp sound wave. Yet ...

The program explores the nature of mechanical waves, questioning how they move and what creates them. It demonstrates wave motion through various experiments, including using a slinky and a wave ...

Electron microscope image of the superfluid wave tank used in the experiments (blue) coupled to an optical fibre which brings laser light in and out of the device. The zoom-in shows the photonic ...
