A rainbow reveals with colors what otherwise remains hidden: light is "refracted" by transparent matter, in this case water ...
Add Yahoo as a preferred source to see more of our stories on Google. In 1920, Danish physicist Niels Bohr proposed that although light (photons) has a dual nature, behaving as both particle and wave, ...
Physicists seem to be obsessed with cats. James Clerk Maxwell, the father of electrodynamics, studied falling feline s to investigate how they turned as they fell. Many physics teachers have used a ...

Laser light and the quantum nature of gravity: Proposed experiment could measure graviton energy exchange
When two black holes merge or two neutron stars collide, gravitational waves can be generated. They spread at the speed of light and cause tiny distortions in space-time. Albert Einstein predicted ...
Measurement-based linear optics implements a huge multi-mode interferometer consisting of beamsplitters (green) and phase delays (blue). The size of the virtual interferometer can be many hundreds or ...

Dark energy — a mysterious force pushing the universe apart at an ever-increasing rate — was discovered 26 years ago, and ever since, scientists have been searching for a new and exotic particle ...
The first experiment to measure gravitational waves from space has been given the green light by the European Space Agency (ESA). The Laser Interferometer Space Antenna (LISA) will use the precise ...
