Driving Question: How and why do theories become generally accepted?
Billowing clouds of matter spun around and around our young Sun. gradually forming just about everything in our Solar System - from meteors and asteroids to all the planets and moons. One planet in particular would enable the creation of even more remarkable complexity. Why? How did the happen?
Leftovers usually aren't all the interesting or important. The leftovers that circled our Sun just after its birth are another story. Gravity helped to separate that matter by density, forming all the different planets in our solar system. Our own planet, Earth, was uniquely positioned at just the right distance from the Sun and composed of diverse elements. This proved ideal for generating just the right circumstances - or Goldilocks Conditions - for greater and greater complexity. But early Earth was much different than the world we know now. What changed and why?
