Pulsare

Of the 70 trillion stars that exist in the cosmos, a pulsar has come into focus. A pulsar is a neutron star

that has mutated from a gas giant of 1-2 solar masses after the material

resources necessary for its existence were used up by a gravitational collapse

in a massive supernova explosion into a dwarf star consisting exclusively of atomic

nuclei with a diameter of 10-20 km. In the process, it develops

the unimaginable rotation speed of 0.001 seconds (the Earth needs 24 hours for

this) and hurls lightning pulses into space that can be received with radio

telescopes. On the outside, these

processes take place measurably with the metric precision of a cosmic atomic

clock. The intraprocessual polymetric

physical mutations, however, remain hidden from us. But this state of existence

also comes to an end when the substance of the atomic nuclei is exhausted. Then the pulsar collapses into

a black hole and disappears into pure massless energy in the singularity. Up to this point, the

composition lives from the unwavering continuity of the cosmic metronome. As a thank you and a tribute,

I dedicate my composition "Pulsars" to the memory of my friends and

teachers Hans Werner Henze and Bernd Alois Zimmermann
