How We Acquired Planets In The Sagittarius Stream

Introduction  Our solar system’s unique layout with four rocky planets, three of which are in the Habitable Zone, and four gas giants in the outer solar system stands apart from all other class G star systems. This paper presents an original hypothesis that around 4.5 billion years ago within a dense trail of stars we call the Sagittarius Stream the Sun captured Saturn, Uranus, Neptune, and their moons from one or more passing stars in the Stream, indicating that such planetary exchanges may actually be common, but only in something like the Stream. We will also look at the Electric Universe theories about planetary capture 6,000 years ago and show that the Grand Tack explains the solar system without any need for recent planetary captures. Ancient rock carvings and Sumerian myths support the Electric Universe hypothesis, which also could explain Venus’s backward spin and Saturn’s rings, but the Electric Universe theory by Wal Thornhill and others that claimed Saturn was a brown dw...

Our Solar System Appears To Be Uniquely Capable Of Supporting Life

     Over 60 years ago the Drake Equation was created not to actually calculate the number of intelligent ET races in the Milky Way, but to "stimulate conversation" at the first meeting of SETI the Search for ExtraTerrestrial Intelligence in 1961. One of the claimed factors that would have resulted in intelligent life forming everywhere was that there would be other planetary systems like ours that had formed over the past 13 billion years of our Universe, and because people took the Drake Equation as something serious, countless science fiction franchises were formed and spun off, all based around the concept that life must have been created in many places just in our galaxy alone.      The Drake Equation calculates the percent of stars in the Milky Way galaxy that are assumed to be class G stars, similar to our Sun, and then starts making wild assumptions. One key assumption is that our solar system must be typical, and that we would eventually find plane...
