Enabling a Universe that Supports Intelligent Life
How did the profound beauty of our Earth, our Solar System, our Milky Way galaxy and indeed our universe unfold? Dark matter, dark energy, and dark gravity have made all the difference in how the universe has developed, and have been key to creating the overall environment that makes life possible.
This book provides insight into what we know and what we hope to learn about dark matter, dark energy, and dark gravity. Each appears to play an essential role in the existence of a universe with characteristics like ours.
We are immersed in a sea of light emanating from ordinary matter that is floating, as it were, on an ocean of dark matter. The dark matter itself floats on the dark energy of the particle vacuum that in turn is embedded within the scaffolding of space-time – which is shaped by the dark gravity effects from all matter and energy.
Only in recent decades have we developed the capability to begin unlocking the secrets of dark matter, dark energy and dark gravity, thus gaining deeper insight into how a universe of this type is possible. It seems that because of dark matter, dark energy and dark (weak) gravity, our universe has the right attributes for the development of complex structure and the evolution of intelligent life that can engage in the quest to understand our world. These “dark” or more hidden attributes of the cosmos have very good outcomes.

The diffuse blue tint is a superimposed mapping of the dark matter distribution in this cluster of over 1000 galaxies. The photo contains over 100 gravitationally lensed images of background galaxies that are distorted by the dark matter in the cluster. Credit: NASA, ESA, and D. Coe (JPL/Caltech and STSci)
