![]() However, it was Karl Schwarzschild (1873-1916) and the little-known Johannes Droste, who independently developed the modern idea for a black hole. ![]() The existence of black holes was first suggested as far back as the late 1700s. Outside the event horizon, v esc < c and there is therefore some hope to escape – if you’re quick enough. Within the event horizon, the escape speed ( v esc ) exceeds the speed of light ( c ), and given that nothing can travel faster than the speed of light, anything inside this sphere is trapped forever. Former KP health minister Atif Khan praised Imran Khan for involving young people in politics and asserted his loyalty to the country.The basic structure of a black hole consists of an object hidden behind an ` event horizon’. Shahbaz Gill, Imran Khan's former chief of staff, claimed disruptions on YouTube and 'X' aimed to hinder the public meeting transmission.

It is not yet known when he will take charge in New Delhi. ![]() Reuven Azar appointed as Israel's new Ambassador to IndiaĪzar is currently serving as the Ambassador of Israel to Romania.

Read all the Latest News, Trending News, Cricket News, Bollywood News , This method has the potential to uncover numerous black holes beyond our immediate cosmic neighbourhood and shed light on the evolutionary process of these enigmatic entities in earlier cosmic eras,” he added. However, gravitational lensing provides us with the opportunity to study dormant black holes, which is currently not feasible when examining distant galaxies. “The majority of the largest known black holes are in an active state, where matter drawn close to the black hole becomes heated and emits energy in the form of light, X-rays, and other types of radiation. Such black holes prove exceedingly challenging to investigate using alternative approaches. Although possessing an immense mass, the black hole displays minimal activity, indicating a relatively low intake of matter and a subsequent absence of intense X-ray radiation. Situated within one of the galaxies comprising the Abell 1201 galaxy cluster, this black hole represents the inaugural discovery utilizing the aforementioned method. By testing thousands of black hole sizes, they eventually identified a solution that aligned with the observed data. Employing advanced computer modelling techniques, the scientists simulated the extent to which light bends around the foreground galaxy housing the black hole. To determine the size of this black hole, the team conducted a thorough analysis of the magnification exhibited by the foreground object in a sequence of images captured by the Hubble Space Telescope. and the leading author of the recent study. Consequently, its discovery is incredibly exhilarating,” stated James Nightingale, an astrophysicist from Durham University in the U.K. ![]() “This remarkable black hole, with a mass approximately 30 billion times that of our sun, represents one of the largest ever detected and pushes the boundaries of our theoretical understanding of black hole sizes. Acting as a natural telescope, gravitational lensing frequently aids astronomers in enhancing the magnification of objects located too far away to be effectively observed by human-made telescopes. ![]() This occurrence arises from the gravitational force of immensely massive objects curving light around them. Out of This World: The discovery of the biggest black hole, 30 billion times the size of the Sun Nasa's Fermi telescope has identified the most powerful blazars known to manīy leveraging the gravitational pull of the foreground galaxy to amplify the background object, astronomers employed a phenomenon called gravitational lensing. ![]()
