Was passiert wenn ein Schwarzes Loch kollabiert?
Die Sternhülle wird dabei abgestoßen und der Kern des Sterns kollabiert zu einem Schwarzen Loch. Die gesamte Masse eines Schwarzen Lochs konzentriert sich in seinem Zentrum. Dadurch ist die Gravitation eines Schwarzen Lochs so stark, dass selbst Licht ihm nicht mehr entweichen kann.
Welche Temperatur haben schwarze Löcher?
Was da in die Akkretionsscheibe des kompakten Begleiters gezogen wird, ist Materie des normalen Sterns – Astrophysiker sprechen auch vom Wirtsstern, der das Loch füttert. Die Scheibe wird in unmittelbarer Nähe des Schwarzen Lochs extrem heiß, etwa 100 Millionen Grad – rund zehnmal heißer als das Zentrum der Sonne!
Who was Stephen Hawking?
Stephen Hawking was an English theoretical physicist, cosmologist, author and Director of Research at the Centre for Theoretical Cosmology within the University of Cambridge.
What disease did Stephen Hawking suffer from?
Hawking suffered from a rare and life-threatening condition of Amyotrophic Lateral Sclerosis, a condition he suffered all of his adult life. The illness started when he was 21 and pursuing his PhD from Cambridge University. For a major part of his later life, he was almost completely paralyzed and communicated…
What did Stephen Hawking contribute to the field of general relativity?
Hawking has made major contributions to the field of general relativity. These derive from a deep understanding of what is relevant to physics and astronomy, and especially from a mastery of wholly new mathematical techniques.
How did Hawking come up with the theory of singularity?
Inspired by Roger Penrose ’s theorem of a spacetime singularity in the centre of black holes, Hawking applied the same thinking to the entire universe; and, during 1965, he wrote his thesis on this topic. Hawking’s thesis was approved in 1966.
