Dark energy is not necessarily uniform if it coexists with matter: its density might vary in space and time due to the interaction between the two gravity sources.



I am grateful to Arthur Chernin, James Overduin, and Robert Wagoner for their valuable remarks and discussion. My special thanks go to Chernin who introduced me to cosmology more than 40 years ago, and encouraged my work on this book.
