Just over a century ago, many prominent scientists believed that luminiferous aether must convey light waves much like air conveys sound waves. Those scientists were right! During an examination of what aether should look like if it actually exists, this book determines the density and pressure of the aether, and how those attributes directly produce mass, energy, and surface tension. Next, the book reveals how the surface tension of black holes produces gravity, electricity, magnetism, and light. In layers, this book describes the various viewpoints needed to reveal the amazing truth about the aether, while also challenging readers with questions and many topics for further research. ERRATA: (page 3) 100 kg is about 1000 N under the influence of normal gravity.
