The original waves. In 1924, French physics doctoral student Louis de Broglie proposed that matter has a wave-like property. De Broglie was inspired by the discovery of wave-particle duality in light.

When two black holes collide, space and time shake and energy spreads out like ripples in a pond. These gravitational waves, predicted by Einstein in 1916, were observed for the first time by the ...

The first part ably introduces the reader to quantum mechanics, founded more than a century ago, yet still perplexing. Is a beam of light a succession of waves or a host of particles?

Various large-scale astrophysical research projects are set to take place over the next decade, several of which are so-called cosmic microwave background (CMB) experiments. These are large-scale ...

An international team of scientists found that powerful shock waves may help explain why black holes spew matter into space, shedding light on one of the biggest mysteries in the universe.

This low-frequency background hum of gravitational waves in our universe was originally attributed to a change, or a "phase transition," that occurred shortly after the Big Bang.New research ...

For nearly a decade, scientists have been hunting for the gravitational wave background, a faint but persistent echo of gravitational waves thought to have been set off by events that took place ...

Physics Gravitational waves produce a background hum across the whole universe. After decades of searching, astronomers have found a distinctive pattern of light, from spinning stars called ...

Identify the features of a sound wave and learn about pitch, frequency, amplitude and loudness in this guide for KS3 Physics students aged 11-14 from BBC Bitesize.
