The double-slit experiment is one of the most famous experiments in physics and definitely one of the weirdest. It demonstrates that matter and energy (such as light) can exhibit both wave and ...

The ALPHA experiment at CERN has released the first results from spectroscopy of antihydrogen, so the study of anti-atoms is starting to get really interesting.

The original double-slit experiment, first performed in 1801 by Thomas Young, showed that light behaves as a wave. Later experiments demonstrated that light also behaves as particles, revealing ...

The multimillion-dollar experiment that was years in the making comes as the federal government makes broad cuts to science ...

Instead, to conserve energy, we have to accept that light must change its wavelength (and hence, frequency and energy, too) as it moves through a gravitational field.

"Einstein said information can't travel faster than light, and in this case, as with all fast-light experiments, no information is truly moving faster than light," Boyd said.

The analysis confirmed that both the input and output of the experiment were single quanta of energy. “They actually use quantum light to show that the energy absorption is a quantum event that ...

The light bulb converts microwave radiation into visible light radiation. As they bounce around, the microwaves quickly settle into a stable pattern with areas of high and low energy. "It's like ...
