CHAPTER 2: THE SCIENCE OF LIFE IN THE UNIVERSE (Part 1 of 2)Astronomy: Next Quiz based on :Go into Chpt 2, Chpt 3.22.1 THE ANCIENT DEBATE ABOUT LIFE BEYOND EARTHGreekefforts marked the first attempts to understand the universe through methods closelyresembling the ones we use in science today.Somescholars argued that there must be life elsewhere, while others, especially Aristotle, arguedjust the opposite.Planetsare named after Mythological figures because our ancestors looked at the sky and attributedwhat they saw to the arbitrary actions of mythological beingsHow did attempts to understand the sky start us on the road to science?"The development of science began with Greek attempts to create models to explain observations of the heavens. Although mostGreek philosophers favored a geocentric model, which we now know to be incorrect, their reasons for this choice made sense at thetime.One of the primary difficulties of the model was that it required a complicated explanation for the apparent retrograde motion of theplanets, with planets going around small circles on larger circles that went around Earth, ratherthan the much simpler explanationthat we find with a Suncenteredmodel."Atnight, the stars circle the sky with different constellations prominent at different times ofyear.People of many early cultures believed that Earth is a flat, motionless disk surmounted by adomelike sky across which the heavenly bodies move.TheSun clearly plays a central role in our lives, governing daylight and darkness
and the progression of the seasons. The Moon’s connection to the tides would have beenobvious to people living near the sea.Thesepowerful influence is why the sun and the moon had such important role in inside religionduring early times, as well as used to keep track of time and season.Chinese,Babylonians, and Mayans also kept record of astronomical observations.
