Stars can exist in other universes
Science News: Fred Adams has calculated that, contrary to some previous claims, stars are not only common in our cosmos but are also ablaze in myriad other universes, where the laws of physics may be drastically different. Even in a cosmos where balls of gas and dust never collapse and ignite to make conventional stars, radiation produced by black holes and clumps of invisible material called dark matter may play the same role as stars, says Adams, a theorist at the University of Michigan in Ann Arbor.
“In fact, all universes can support the existence of stars, provided that the definition of star is interpreted broadly,” notes Adams in the August online Journal of Cosmology and Astroparticle Physics.

Since cosmologists have gone so far as to speculate that even if our universe is of infinite spatial extent,it may be just one universe on an infinite tree of universes each universe giving birth to innumerable baby universes during each differential unit of time. These baby universe, or at least some of them, inflate and give birth to additional universes in a never ending fractal tree, thus the reason for the name Chaotic Inflationary Theory for the associated theory of the cosmos.
If there can be one such fractal verse or multiverse, why could their not exist innumerable fractal trees or fractal-verses that are either very weakly casually coupled or completely non-coupled.
Perhaps there are higher levels to this hierarchy such as degenerate or completely separate scalar fields wherein each scalar field gives rise to a perhaps ever growing set of innumerable fractal verses. Perhaps there may be no end to the level of such hierarchies.
