"The Cosmic Energy Inventory"

(Abstract)
We present an inventory of the cosmic 
mean densities of energy associated
with all the known states of matter 
and radiation at the present epoch. 
The observational and theoretical bases 
for the inventory have become rich enough 
to allow estimates with observational 
support for the densities of energy 
in some 40 forms. The result is a global 
portrait of the effects of the physical 
processes of cosmic evolution.
