But do we really know this? We have to get an idea of the biggest we can think of, to answer this question. This can only work if, since the beginning, the universe follows everywhere the same rules. The rules, which we know from our local cosmic neighborhood. That is to say, all laws of nature are valid at any place at any time - what is not self-evident.[[BR]][[BR]]The presentation will explain the known universe by continuously traveling farther away into space and back in time. It will be explained how astronomers measure the distances in the universe to get an idea of its size. And, we will follow the evolution of the universe starting at the most extreme physical state of the universe - the big bang.[[BR]][[BR]]Presentation: German [[BR]][https://svn.mpia.de/trac/gulli/att/raw-attachment/wiki/AlteVortraege2015S2/2015-09-18_Wie_gross.pdf Slides: German][[BR]]Questions: German, English[[BR]][[BR]][[BR]]'''The history of light in the universe[[BR]]'''[[BR]]Presentation: German [[BR]][https://svn.mpia.de/trac/gulli/att/raw-attachment/wiki/AlteVortraege2015S2/2015-09-18_Geschichte_des_Lichts.pdf Slides: German][[BR]]Questions: German, English || |
