DESCRIPTION:Greetings\,The Physics seminar this week will meet on Friday\, 
 November 8 at 3:00 pm.  You can join online at this link:  https://wright.
 webex.com/meet/sarah.tebbensThe speaker this week will be Dr. Andrea Ghez 
  (pre-recorded).  The talk was originally presented in 2020 when Dr. Ghez 
 was awarded a 1/4 share of the 2020 Nobel Prize in Physics.  The talk is t
 itled\, “From the Possibility to the Certainty of a Supermassive Black Hol
 e.'I hope you can join us\,Dr. Tebbens---Black holes and the Milky Way’s d
 arkest secretThe 2020 Nobel Prize in Physics was shared by three scientist
 s.Roger Penrose invented ingenious mathematical methods to explore Albert 
 Einstein’s general theory of relativity. He showed that the theory leads t
 o the formation of black holes\, those monsters in time and space that cap
 ture everything that enters them. Nothing\, not even light\, can escape.Re
 inhard Genzel and Andrea Ghez each lead a group of astronomers that\, sinc
 e the early 1990s\, has focused on a region called Sagittarius A* at the c
 entre of our galaxy. The orbits of the brightest stars closest to the midd
 le of the Milky Way have been mapped with increasing precision. The measur
 ements of these two groups agree\, with both finding an extremely heavy\, 
 invisible object that pulls on the jumble of stars\, causing them to rush 
 around at dizzying speeds. Around four million solar masses are packed tog
 ether in a region no larger than our solar system.Using the world’s larges
 t telescopes\, Genzel and Ghez developed methods to see through the huge c
 louds of interstellar gas and dust to the centre of the Milky Way. Stretch
 ing the limits of technology\, they refined new techniques to compensate f
 or distortions caused by the Earth’s atmosphere\, building unique instrume
 nts and committing themselves to long-term research. Their pioneering work
  has given us the most convincing evidence yet of a supermassive black hol
 e at the centre of the Milky Way.“The discoveries of this year’s Laureates
  have broken new ground in the study of compact and supermassive objects. 
 But these exotic objects still pose many questions that beg for answers an
 d motivate future research. Not only questions about their inner structure
 \, but also questions about how to test our theory of gravity under the ex
 treme conditions in the immediate vicinity of a black hole”\, says David H
 aviland\, chair of the Nobel Committee for Physics.
