"The mind is a compact, multiply connected thought mass with internal connections of the most intimate kind. It grows continuously as new thought masses enter it, and this is the means by which it continues to develop."

Bernhard Riemann On Psychology and Metaphysics ca. 1860

Heraclitus and Astronomy

It is remarkable that when speaking of events billions of years in the past, the use of verbal tenses here is so very muddled. This galaxy obviously no longer exists as such. We are imagining a steady state of galactic evolution for no apparent reason. Take heed of the words of Heraclitus some three millennia ago on this subject.   How has the lawful evolution of star formation changed and why?

Artist’s impression of the monster galaxy COSMOS-AzTEC-1. This galaxy is located 12.4 billion light-years away and is forming stars 1000 times more rapidly than our Milky Way Galaxy. ALMA observations revealed dense gas concentrations in the disk, and intense star formation in those concentrations.
