Cosmic voids don't have black holes, so is it reasonable to assume black holes are the cause of Time? Does Dark Matter have access to time?
A long time ago (around 13.8 billion years before now), there was no comic web. There were, of course, no galaxies and no stars. There were only the fundamental components of the universe: dark matter, hydrogen, helium and a little sprinkling of lithium just for flavor. All this stuff was as homogenous as the milk you buy at the grocery store: pretty much evenly spread throughout the nascent universe.I'm puzzled here as to the defintion of a cosmic void. Is this just space?
Cosmic voids are spaces millions of light years across that contain fewer and more sparsely distributed galaxies than the average. Found between voids are galaxy clusters, the largest known structures formed in the universe, as heavy as 1 million billion solar masses. Gravity controls how quickly galaxy clusters grow, as well as their density.Cosmic voids don't have black holes, so is it reasonable to assume black holes are the cause of Time?

Instead of individual galaxies, we see huge walls and tendrils containing thousands of galaxies; filaments of galaxies connect in nodes. These structures are huge; hundreds of millions of light-years across, containing thousands of galaxies. But the voids between these clusters can be even larger.The definition depends on the speaker, because there are no definitions
