Physics experiments have changed the world irrevocably, altering our reality and enabling us to take gigantic leaps in technology. From ancient times to now, here's a look at some of the greatest ...

Physics is supposed to be predictable. Drop a ball, and gravity pulls it down. Heat water, and it boils. Light travels in straight lines. Yet throughout history, scientists have encountered ...

Imperial physicists have recreated the famous double-slit experiment, which showed light behaving as particles and a wave, in time rather than space. The experiment relies on materials that can change ...

Quantum physics is the realm of the strange. And one of the strangest discoveries in the field is also one of the most fundamental: Particles fired at barriers with two slits in them can act like ...

Add Yahoo as a preferred source to see more of our stories on Google. A new accelerating wave equation links changing light speeds to relativity, momentum conservation and the arrow of time. (CREDIT: ...

Researchers have combined a laboratory wave tank, validated CFD simulations, a compact analytical formula, and a ...

Scientists have discovered “unexpected physics” by opening up “slits” in time, a new study reports, achieving a longstanding dream that can help to probe the behavior of light and pioneer advanced ...

Physics provides the fundamental rules that govern our universe — or so we thought. Throughout history, brilliant minds have uncovered phenomena that shattered our understanding of reality, forcing us ...

The most beautiful experiment in physics, according to a poll of Physics World readers, is the interference of single electrons in a Young’s double slit. Robert P Crease reports Simply beautiful – the ...

New experiments with cuprate materials explore a connection between so-called charge-density waves and a light-induced state that resembles superconductivity. In 2011 physicists made a surprising ...
