Gas clouds across the universe are known to absorb the light produced by distant massive celestial objects, known as quasars. This light manifests as the so-called Lyman alpha forest, a dense structure composed of absorption ...
Today, many research teams worldwide are trying to detect dark matter, an invisible substance that is believed to account for most of the matter in the universe. As does not reflect or emit light, its presence has been indirectly ...
While many studies have hinted at the existence of dark matter, a material that does not absorb, reflect or emit light, this elusive substance has not been directly observed so far. Over the past few decades, many teams worldwide ...
Researchers at Massachusetts Institute of Technology, Hebrew University of Jerusalem, and Ohio state University recently carried out a study examining the possible effects of a first-order phase transition in a confining ...
Past physics theories introduced several fundamental constants, including Newton's constant G, which quantifies the strength of the gravitational interaction between two massive objects. Combined, these fundamental constants ...
In September 2020, the LIGO/Virgo collaboration, a large team of scientists working at different universities worldwide, announced that they had detected most massive gravitational wave binary signal observed to date, which ...
The North American Nanohertz Observatory for Gravitational Waves (NANOGrav) is a gravitational-wave detector that monitors areas in the vicinity of Earth using a network of pulsars (i.e., clock-like stars). At the end of ...
Many cosmologists believe that the universe's structure is a result of quantum fluctuations that occurred during early expansion. Confirming this hypothesis, however, has proven highly challenging so far, as it is hard to ...
Axions and dark photons are two of the most promising types of particles for unveiling new physics. The axion scalar field explains the absence of an electric dipole moment for the neutron, while the dark photon resembles ...
The concept of universal physics is intriguing, as it enables researchers to relate physical phenomena in a variety of systems, irrespective of their varying characteristics and complexities. Ultracold atomic systems are ...
