Velokovsky (and Ackerman) wrote about the birth of Venus, and Mars waging war on the Earth as an actual hypothesis as to how the solar system got to how we view it today. Hogan, as was often his style, took that idea and wove a fictional story around it.
I wish I had recommendations of other lesser known authors of a similar style, but I've never encountered any. For the most part I probably read the same books that most techies do, Asimov, Gibson, Stephenson. It was just a fluke that my mother bought me the fourth book in Hogan's Giants series for Christmas one year, and despite not having read the previous three books I was hooked.
