This "easy to read" book explores how space forms a major part of the cosmos. The book shows some simple experiments that explain how space itself has density and mass. It explains how space influences the way that the various parts of the cosmos interact. How we see the cosmos and even how space influences time and gravity.With this knowledge, and the observations made by various scientists, I explain: -1. why light does not always travel in a straight line,2. why the speed of light is not a constant, 3. the role of space and energy in the evolving cosmos,4.

how space influences time,5. how black holes can form in space,6. how space creates the effect of gravity,There is no complex mathematics, no complex phrases, no "space-time-continuum", simply practical observations and what I think are logical conclusions.
