Black Holes and Our Cooling Universe

There is ample evidence that the Universe is cooling down. And there are theories why this is occurring (notably an expanding Universe). In this article we discuss, in a qualitative way, the role that black holes might play.

As discussed in the previous article “On Photons and Gravity”, there are theoretical reasons why the photons captured by black holes gradually deplete the net photon flux throughout the Universe. And the Universe’s temperature is a function of this flux. Hence black holes may play a role in Universal cooling. And as the number and gravitational strength of these phenomena increase, so does the rate of cooling.
