What is Anaxagoras's Universe?

Anaxagorea's worldview:

Everything has existed in some form or another since the beginning of time, but at first it was just tiny bits of itself, infinite in quantity and irrevocably merged with everything else in the universe.

Everything was contained within this mass, albeit in a disorganized and indistinguishable form, with an endless number of both homogeneous and heterogeneous components.

According to Anaxagoras, worlds similar to our own could be created by the cosmic rotary motion.

The later-born Plato agreed with Anaxagoras when he noted that the moon eclipse is caused by Earth's blocking of the moon's light.

and Anaxagoras on Wikipedia

Anaxagoras proposed a theory of the universe where everything is composed of infinitely divisible particles called "nous" or "mind." These particles have different properties and combine to form all material objects. According to Anaxagoras, the universe is governed by a cosmic mind or intelligence that sets everything in motion and controls the arrangement of these particles.
