Versuchst du dann eigentlich im Grunde dei, das Le-, dein Leben lang zu gucken, wo liegt eigentlich die Grenze?

Auch, ja.

Also wenn da 'ne Grenze ist, versuche ich daran zu rütteln, aber ich kann auch akzeptieren, dass sie da sind.

Und tatsächlich, wenn du dir die Physik anguckst der letzten 100 Jahre, dann haben wir natürlich unfassliche, äh, Entwicklungen mitgemacht.

Was wir alles heute können, machen, was wir sehen können.

Also wir können heute Bilder sehen, die keine Generation vor uns jemals sehen konnte.

Ja, wir haben Bilder, scharfe Bilder vom Mars.

Also warum ja, natürlich?

Briefly, before we get to EHT, could you talk about radio astronomy and how the very long baseline interferometry telescope works?

Yeah, I mean, radio astronomy, I think, has a special role because it was sort of developing in the 30s.

Krawczynski in the US, you know, found there was, he was investigating radio, for radio communication, and there was some noise, and he figured out that this noise was coming from the Milky Way.

The cosmos was making radio waves.

That was the first time that we were doing astronomy in a color that's not visible to the naked eye, so to speak.

we were looking at the universe at different electromagnetic waves.

And radio is light as the light we see with our naked eye, just at a much lower frequency.

Could you talk about that and the role of Fourier transform in producing an image from this data?
