Physicists Measure Pressure Distribution inside Proton

The proton, one of the components of atomic nuclei, is composed of fundamental particles called quarks and gluons. A team of physicists at the Department of Energy’s Thomas Jefferson National Accelerator Facility has found an extremely high outward-directed pressure from the center of the proton, and a much lower inward-directed …

Physicists Entangle Two Macroscopic-Scale Objects

Entanglement — an intriguing phenomenon in which two distant objects can manifest correlations, even if they are far away from each other — has now been made a reality in macroscopic-scale objects. An illustration of tiny drumheads prepared on silicon chips used in the experiment; the drumheads vibrate at a …

Physicists Find New Way of Exploring Cosmic Microwave Background

A team of Canadian physicists has developed a new way to improve our knowledge of the Big Bang by measuring radiation from its afterglow, called the cosmic microwave background radiation. The team’s results, published in the journal Foundations of Physics, predict the maximum bandwidth of the Universe, which is the …
