2023-12-14 11:06:24 Energy sources are endless and are sometimes found where you least expect them. In China, researchers from Tianjin University hypothesize that the power of black holes could be harnessed as a battery to provide energy, as reported in a study published on November 29, 2023 in the journal Physical Review D. A black … Read more
2023-12-03 18:24:57 More than 50 years ago, military satellites put into orbit by the United States discovered gamma-ray bursts, in English gamma-ray bursts or GRB. These satellites had the mission of detecting prohibited nuclear explosions in or outside the atmosphere. But quickly, the scientists in charge of the satellites understood that these events were cosmic … Read more
2023-11-07 01:19:00 LOS ANGELES, Nov. 6 (Xinhua) — Astronomers have discovered the most distant black hole ever detected by X-rays, using NASA telescopes, the space agency said Monday. The black hole is at an early stage of growth that has never been observed before, with its mass similar to that of its host galaxy. By … Read more
2023-10-26 01:49:00 Scientists question whether the entire universe could be a black hole and we live in a black hole. In conclusion, a black hole or a red hole can be whatever it is…but right now the environment on Earth is no different from a black hole because the environment is deteriorating. Humans only think … Read more
2023-09-22 18:05:27 Gravitational wave detectors on Earth like Ligo and Virgo — or like the one expected to fly into space by the 2030s, the Lisa (Laser Interferometer Space Antenna), a mission which will be led by Esa in collaboration with NASA —, are interferometers. They do not work directly like telescopes or regular glasses … Read more
2023-09-09 14:11:18 Among the stars of astronomyNeil Gehrels Swift Observatory, in English). This multi-spectral telescope (hard and soft X-rays, ultraviolet, visible light) from NASA is still operational despite its 20 years of age since it was launched in 2004. As explained by Phil Evans, astrophysicist at the university from Leicester in the United Kingdom and … Read more
2023-09-02 17:09:00 Certain models of dark matter postulate the existence of very heavy particles which would pass through matter and be indistinguishable from Big Bang neutrinos in detectors on Earth. But these particles could transform neutron stars into black holes of abnormally low masses, like those that are perhaps detected with gravitational waves. In retrospect, … Read more
2023-08-28 17:21:32 Tidal rupture events are cosmic catastrophes that occur when a star passes too close to a supermassive black hole. Simple theory in the early 1980s, they are observed and dissected with the gaze of X-ray telescopes in space. We have just specified the composition and the mass of the star which was destroyed … Read more
