Speaking of the #MichelsonMorley experiment, if the students in the departments of #Mathematics and #Physics and #Astronomy don’t have an annual (Emmy) #NoetherDragShow , I will be very disappointed. 😔 #ScienceIsFun

I must not have any astronomers among my followers, because although all voting options would make any city famous/infamous, nobody voted for the correct answer! 🤷🏻‍♂️

“No ether drag observed” during the #MichelsonMorley experiment at what is now #CaseWesternReserveUniversity in #Clevelan #Ohio is of existential importance for everyone and everything on planet Earth 🌎. It prove that we are moving in space through a vacuum (no ‘ether’)!

**Who is Aithir?**

Ether, that is how they called the hypothetical medium in which light travelled - until about 150 years ago. It was somehow magic because nobody had proof that it existed. It just lived in some mind experiments. Latest in the year 1887, this haunting came to an end with the famous Michelson-Morley experiment that they still teach at school.

But the term, which could be traced back to the Greek God Aither or Aithir, stayed alive. It became a synonym for TV transmissions and was used as the name of one of our most important network specifications, the Ethernet.

So fifteen years ago, when I searched for a suitable alias for all these accounts in the social networks that popped up at that time, this name seemed perfect for me. Many interpretations and connotations, so cool. One year later, it wore down already and that user name felt as nerdy as collecting D20 dices (👀)

But my name was there to stay.

**Wer ist Aithir?**

Äther, so nannte man bis vor etwa 150 Jahren das Medium, in dem sich Licht bewegen sollte. Ein magisches Medium, das man zu dem Zeitpunkt noch nicht nachweisen konnte. Der Spuk hatte spätestens 1887 mit dem Experiment von Michelson-Morley (das viele aus der Schule kennen) ein Ende.

Dennoch blieb der Begriff, der auf die griechischen Gott Aither oder Aithir zurückzuführen ist, haften. Er wurde zum Synonym von TV Übertragungen und stand Pate für eine der wichtigsten Netzwerk-Spezifikationen unserer Zeit, dem Ethernet.

Als ich mir vor 15 Jahren einen passenden Namen für die aufpoppenden sozialen Netzwerke suchte, fand ich diesen Begriff noch perfekt - viel Zweideutigkeit, viele Interpretationen. Schon ein Jahr später war mein Pseudonym für mich so nerdig, wie D20 Würfel zu sammeln (👀).

Dennoch hat mein Name bis heute überlebt.
