Our current understanding of physics suggests that there are two main types of matter in the universe known as dark and baryonic matter. Dark matter is made up of material that scientists cannot directly observe, as it does ...
(Phys.org) -- Last year, astronomers discovered a quiescent black hole in a distant galaxy that erupted after shredding and consuming a passing star. Now researchers have identified a distinctive X-ray signal observed in ...

(Phys.org) —A research team with members from the U.S. and Italy has succeeded in building an integrated graphene digital circuit that is able to function at gigahertz frequencies. In their paper published in the journal ...
Oscillatory behaviors are ubiquitous in nature, ranging from the orbits of planets to the periodic motion of a swing. In pure crystalline systems, presenting a perfect spatially-periodic structure, the fundamental laws of ...
