Modern Astronomy is a pseudoscientific validation of the Star Trek universe for the purpose of making you think that Biblical prophecy about stars falling to Earth is ludicrous.
Axiom III is "Earth is the Center of the Observable Universe." We can deduce Principle I from the following physical evidence, empirical observations or established theories which are part of Axiom III.
Theoretical and empirical are opposites, like dark and light. Empirical means verified by direct observation. Theoretical can't be seen, it's what we hope for, which is why we became a scientist.
An overwhelming majority of people believe that we observe the Earth orbiting the sun but it’s not an observation, heliocentricity is theoretical. We observe the cosmos from Earth, which makes it Geocentrospheric.
Supposedly, distant stellar objects are so large that they have to be very far away. Either that or they're so far away that they have to be very large. It's a phenomenon we call the geometry of despair.
It’s ironic that today is April Fools’ Day because today we (that's me and the Holy spirit) begin to make the case that the universe is Geocentrospheric, but this isn’t a joke.
