Albert Einstein and Niels Bohr had an ongoing rivalry about the true nature of quantum mechanics, and came up with a thought ...

Physics, particularly forces and motion, can be challenging. By observing everyday motion, conducting simple experiments, and understanding Newton's laws in plain language, the concepts become more ...

The constancy of the speed of light is a pillar of modern physics, but questions persist about its absolute universality.

If you drop a light object and a heavy object from a tower, which one reaches the ground first? As you may recall from high school physics, this is a trick question. Neglecting air resistance, they ...

Stefan Hutzler and Denis Weaire are in the School of Physics, Trinity College Dublin, Ireland. Their postgraduate student Ali Irannezhad currently performs his experiments in his home in Tehran, Iran.

Preliminary results from two experiments suggest something could be wrong with the basic way physicists think the universe works — a prospect that has the field of particle physics both baffled and ...

Does dark matter follow the same laws as ordinary matter? The mystery surrounding this invisible and hypothetical component ...
