Cosmological Entropy and Black Holes in Galactic Halos
Abstract
In this talk we discuss intermediate mass black holes (IMBHs) by their amplilification of distant sources; MACHO searches have studied event times 2 h t0 2 y corresponding masses in the range 10-6 M M 100 M. We suggest that larger masses up to 106 M are also of considerable interest by arguments about the entropy of the universe. One percent by mass of dark energy can provide ninety-nine percent of total entropy.
