What are the key points from the attached notes on the Voyager Golden Record and early solar system models?

The Voyager Golden Record contains Earth's knowledge for extraterrestrials, attached to Voyagers 1 and 2. Early solar system models include heliocentrism (sun-centered universe by Copernicus and Galileo), geocentrism (Earth-centered universe), and theories by Descartes, Buffon, and Kant on planetary formation.

[{"Voyager Golden Record":["Contains a comprehensive collection of Earth's knowledge.","It is a disc included in both Voyager 1 and Voyager 2.","Created to inform extraterrestrial beings about Earth's existence and send a message during their space journey."],"Early Solar System Models":{"Heliocentrism":["Derived from the Greek word 'helios' meaning sun.","Proposes that Earth and other planets orbit the sun, with the sun at the center of the universe.","Championed by Copernicus, who published 'De revolutionibus orbium coelestium'.","Supported by Galileo Galilei, who found it more convincing than the geocentric model."],"Geocentrism":["Believes Earth is the center of the universe."],"Solar System Theories":[{"Rene Descartes (Vortex Theory)":["Suggested that the sun is at the center of a vast vortex of invisible rotating matter, with planets moving like leaves in a whirlpool.","Every star is a sun with its own vortex, contributing to a cosmos of various vortices."]},{"George Louis Leclerc, Comte de Buffon (Collision Theory)":["Proposed that a comet striking the sun broke off debris that became planets.","Earth was initially hot but cooled over time, leading to the formation of dry land and oceans.","Estimated this process took over 75,000 years."]},{"Immanuel Kant (Nebular Theory)":["Details not fully elaborated in notes but generally known for proposing that the solar system formed from a large cloud of gas and dust."]}]}}]
