Publisher description
There was a vast period of time from the origin of our universe to the formation of Earth. The Big Bang is estimated to have occurred 13.6 billion years ago, and the Earth is dated at 4.8 billion years. Evidence for life on Earth goes back to only 4.1 billion years. That leaves a period of about 8.8 billion years of existence before Earth formed, 9.5 billion if we presume a lifeless first billion years on Earth. We consider the times and places before life on Earth that might have provided suitable environments for life. As the universe changed considerably during this vast epoch, there is much time and space to which we can apply our imaginations and observations in estimating where, when, and in what circumstances life might have arisen. Is Earth life de novo, or derived from previous life?"
No book nor any review article or paper covers this cosmic time period from the point of view of its potential for life.Provides multiple hypotheses on the origin of life and distribution of living organisms in space, which go beyond the accepted dogma that life originated on EarthExplores the diversity of physical environments that may support the origin and evolution of lifeIntegrates contemporary views in biology and cosmology, and provides reasons that life is far more mobile in space than most people expectIncludes access to a companion web site housing supplementary information such as animated computer simulations
