Wormholes — shortcuts that in theory can connect distant points in the universe — might be linked with the phenomenon of quantum entanglement, where the behavior of particles can be connected regardless of distance, researchers say. Read the associated APS Physics...
A simple model of forest fires could help explain the distribution of the sizes of earthquakes and their aftershocks, a theoretical physicist says. Geoscientists say they have reservations about the accuracy of the bare-bones model, but they welcome the effort to account...
A planet-hunting NASA spacecraft has not yet detected any sign of black holes with about the mass of Earth's moon in the Milky Way galaxy, limiting the chances that such objects could make up most of the dark matter that has mystified scientists for decades. Read the associated...
A re-evaluation of a 2005 measurement of the lifetime of the neutron has deepened the mystery of why two different experimental techniques yield two different neutron lifetimes. After recalibrating a key part of their beam experiment, physicists confirmed that their value...
Improved model for neutron star crust solves one problem while creating another.
An entangled state of two quantum bits can be created and stabilized using interactions that are normally thought to be detrimental, according to two international groups of researchers. While the groups studied two different physical systems, they have both shown that an...
