Historical Cosmologies

Cosmology and the Origin of Life

Okay, our task is to now remove the earth from the center of the Universe and come up with something more sensible:
Elements of the Universe at this time (Aristotle):

Geocentric Cosmology
Stars and planets on perfect crystalline spheres
Universe is perfect and Changeless

Problems:

observed transient phenomena (comets, novae, variable stars) --> attributed to disturbances in the upper atmosphere of the earth
Aristotelian model makes a definite prediction --> all planets and stars should move in the same direction . But Mars was known at that time to sometimes move in the opposite direction for a brief period of time (this is known as retrograde motion)
So Ptolemy builds an incredible complicated machine to preserve the geocentric model and account for retrograde motion ( The correct explanation)
This model stood for 1500 years before anybody asked this relevant question

Back to the Original Idea Alert:
Cardinal Nicholas of Cusa (15th Century) through a lot about cosmology and came up with the following;

Every direction is relative
The Universe has its center everywhere
The above two means there can be no UNIQUE place in the Universe

The Earth may not be stationary
Wherever one stood in the Universe, the same pattern of stars would be strewn out before them (homogeneity)

Thus for the first time we see the ideas of relativity, homogeneity and non-uniqueness expressed.
Copernicus embraces the non-uniqueness idea and then asks why should the earth be at the center - lets put the SUN there

This is the First Heliocentric Cosmology
Evolving Models of the Solar System and The Scientific Method:

Galileo sees a mini solar system around Jupiter

Tycho searches for stellar parallax --> sees none --> Aarogant rejection of Copernicun Model

Tycho publishes data --> Kepler makes Geometrical Model

Newton invents gravity, calculus but forgets about the speed of light

Einstein invents causality and gravity as curved spacetime
