Gamma-ray bursts are the brightest electromagnetic events that occur in the Universe, when a few seconds of the burst release as much energy as the Sun would emit in 10 billion years. The powerful explosion, BOAT or GRB 221009A, occurred approximately 2.4 billion light-years from Earth, in the direction of the constellation Sagittarius, and lasted … Read more

Experimental verification of the Bell inequality is also of practical importance, as it allows confirmation of the existence of true … Read more
Two astrophysicists at the Harvard-Smithsonian Center for Astrophysics have proposed a way to observe what could be the second closest supermassive black hole to Earth, a giant 3 million times the mass of the Sun, hosted by the dwarf galaxy Leo I. According to the “Space” website, the supermassive black hole, called Leo I *, … Read more

Astrophysicists at the University of Nottingham suspect that a “fifth force”, mediated by a hypothetical particle called a symmetron, may be at work in space. The Lambda cold dark matter model (ΛCDM) is the current standard model used to explain cosmology and understand the universe.. However, there are several puzzling scientific challenges to this model … Read more
