### Cooperation makes it possible!

A true expert round had gathered a week after the first release of the images of a black hole. Professors Luciano Rezolla, Heino Falcke and Michael Kramer met in an auditorium of the Goethe University Frankfurt am Main and reported on the theories and practice of the massive gravity monster and its photographs. All three were involved in the Event Horizon Telescope (EHT), but only the first two in the European Commission represented the project on site.

Beginning with a simple introduction to the principle of gravitation, in depth to the two most well-known theories of Newton and Einstein, every listener became aware that we are reaching the limits of our imagination and physics with a phenomenon of this magnitude. Therefore, one hopes that this "revolution" brings us closer to the desired "world formula" (the unification of relativity and quantum mechanics). Nevertheless, gravity remains the most mysterious force in the universe.

### To the emergence of this century recording

It was urgently necessary to achieve a sufficiently high resolution in order to get something so far away visible. However, this seemed impossible with today's technology, since the following formula applies:
$Aufloesung=\frac {\lambda}{d}$$Aufloesung=\frac {\lambda}{d}$ The wavelength of the light (λ) could not be further reduced, so that consequently only the diameter of the telescope (d) used came into question. And so you came up with the idea of not building a new one with a record diameter, but simply 9 interconnect radio telescopes distributed throughout the world. The result: a telescope with earth diameter!

Another condition was a clear sky for perfect shooting conditions. What is already hard enough to guarantee in one place had to occur simultaneously through this principle throughout the globe. And as unlikely as this is otherwise, almost exactly two years ago, it was really fortunate to have unimpeded visibility for days and days. This was written on 11.04.2017 cosmology history!

An unbelievable amount of data (12600 Terrabytes!) Was evaluated for days and it would be an understatement to say that the results surprised: You were really afraid of measurement or other errors because the data was just too perfect for the simulations and calculations. The major project of over 200 scientists from 18 countries has created a milestone in astronomy. Future plans include both an improvement in telescope satellite images and sighting of other galactic centers. Our own is not yet photographable, but it is hoped to further progress to accomplish this in the near future.

So it remains exciting, which further scientific findings still arise. Be it theoretical, in the form of the new understanding of gravity, or even practical, when new detailed recordings of black holes allow!
