People here should know about the Electric Universe theory. Trying to solve the problem of the Cosmos like trying to solve a complex puzzle. Every time we think we have an answer, a thousand new questions pop up.
During the Dark Ages, people thought that the Earth was flat. In the case of a Hindu belief, the Earth rested on a giant turtle that swam in an ocean current. While meant to be allegory, the hindu being interviewed took it as literal. When asked who supported the turtle, the hindu said "It's turtles all the way down."
However, experiments done in the Hellenistic Age using shadows showed that the Earth is actually not a flat two dimensional object, but round like a ball. However, people believed that our star orbited the Earth. However, Aristarchus did some experiments and said that the Earth oribited the Sun (for our purposes, we will call it Sol). When Newton expanded on Galileo's proposals for Gravity, he said Gravity is the mechanism which the Earth revolved around Sol. And soon, Gravity became the mechanism that moves all things in the Cosmos.
Once Sol was a fire in the sky. However, later, it wasn't seen as a camp fire in later times, but it became a condensed nebula of gas and dust. In our Nuclear Age, it's seen as thermonuclear.
However, we've discovered and harnessed something that is more powerful than gravity. Electromagnetism is a billion, billion, billon, billion times more powerful than gravity (about 10^36 times more powerful than Gravity). Once Astrophysicists understood this number, they should have thrown gravity out the window as the King of the Cosmos. They did not.
The Red Shift has been disproven as doppler shift, though. Thanks to Halton Arp, the red shift can be used to figure out the age of an object.
