A good, informative read. The essays are laid out in such a way that a scientific virgin can understand what is being presented and decide for themselves whether to accept or refute each of the arguments presented herein.
This is also the story of Vulcan, the 1st, IntraMercurian planet that scientists desperately sought for a century based on orbital and gravitational anomalies of the planet Mercury - a search that finally led to the Second Law of Gravitation - in that any gravitational field of the size and power of Sol or larger, will create a gravitational bulge that will mimic in all aspects except that of the physical an actual planet.
In the Sol system, this bulge would go by the name of Vulcan. [or Hephaestus if you prefer the Greek to the Roman name] ( )
