The 2020 Nobel Prize in Physics has been award to Roger Penrose , Reinhard Genzel , and Andrea Ghez for theirgroundbreaking theoretic and observationalwork on black pickle .
one-half of the 10 million kronor ( about $ 1.12 million ) prize goes to Penrose for " the discovery that fatal hole formation is a full-bodied prediction of the general possibility of relativity theory . " The other half is share between Genzel and Ghez for " the discovery of a supermassive compact object at the center of our beetleweed . " The scientist and their squad discovered Sagittarius A * , thesupermassive pitch-black jam at the center of the Milky Way .
Roger Penrose ’s work was crucial to our discernment ofblack hole . Einstein ’s hypothesis of general Einstein’s theory of relativity provided the mathematical peter to identify an physical object so thick that nothing , including light , could get away it . But Einstein did not trust they existed . It was Penrose who came up with a example that described how such an extreme target could form . His revolutionary 1965 paper is the basis for most of the field today .
The other half of the prize is experimental . Reinhard Genzel and Andrea Ghez are both leadership of group of astronomer that over the last three decennary have studied the stars at the very substance of the Milky Way . The orbits of these stars suggest the bearing of an improbably dense aim ; one packing over 4 million times the mass of the Sun into an aim that would fit well within the orbit of Mercury .
Both team have proceed monitoring the centre of the coltsfoot , offer crucial trial for general relativity . They showed thatgravitational redshiftreally does take place and that star do follow orbits that can not be explained withNewton ’s practice of law of gravity .
When asked what a black hole is , Professor Ghez serve frankly about the mystical objects that seem to head to more inquiry the more they are studied . “ We do n’t know , " Ghez , a professor at UCLA , enjoin . " We have no idea what ’s inside the black hole . And that ’s what makes these thing such alien objects that really map the partitioning of our physical understanding , of the jurisprudence of physical science . ”
Professor Ghez is the fourthwoman to receive the Physics Prize(tying female Nobel plunder succeeder with male Nobel winner namedJames , if you ’re go on mark ) out of more than 200 laureates since the Prizes get in 1901 .
“ I ’m thrilled to receive the booty , " Ghez said . " I take very seriously the responsibility associated with being the fourth woman to receive the dirty money . I trust I can revolutionise other young charwoman into the line of business . It is a study that has so many pleasures , and if you are passionate about the skill there is so much that can be done . ”
