“Scientists have long observed that the capability for a material to absorb electromagnetic radiation — a wave of energy in ...

The first semester of an undergraduate physics course invariably spends a lot of time on two big ideas: The momentum principle and the work energy principle. Both deal with forces acting on an ...

According to quantum physics, energy can be 'borrowed' -- at least for some time. Energies lower than zero are possible, much like a bank account that can be overdrawn. There are, however, certain ...

Low-energy experimental physics, on the other hand-- work in Atomic, Molecular, and Optical (AMO), or "Condensed Matter" (CM, the study of solids and liquids) physics, among others-- is much more ...

Dark energy may have a completely unknown aspect of physics acting as an accomplice in its efforts to defy gravity, suppressing the growth of large-scale structures like galaxy superclusters.

Astronomy Unknown physics may help dark energy act as 'antigravity' throughout the universe. Astronomy A 'cosmic car radio' could help scientists tune in to dark matter within the next 15 years.

Astronomers have spotted the highest-energy outburst of light from a pulsar ever seen. The discovery could indicate new physics around these incredibly dense, rapidly spinning dead stars.
