In these regions the formations of gas, dust and other materials 'clump' together to form larger masses, which attract further matter, and eventually will become big enough to form stars." -Wikipedia Our ancestors envisioned an aeolian universe, and longed to listen to the 'music of the spheres'. They may not be faulted for thinking as such, as these marvels of nature do indeed bring to mind the whalesong of the deep oceans.
