If the Earth was the center of the Solar System, you'd have to unlearn a lot of what you know about the Universe. The Earth would now be in the middle of everything. Surrounding us would be several layers of other celestial orbits. Right next to us would be the Moon.

What did Aristotle believe about atoms?

As a philosophy, this model worked very well; however, it did not explain why planets appeared to slow down and speed up in their movements. Nevertheless, Aristotle's universe was the accepted model until the 17th century.

What if Earth was closer to the center of the galaxy?

The closer you get to the heart of the galaxy, the tighter stars are packed together. Because of this high star density, the Earth would be blasted with a lot more radiation than what the Sun throws at you right now. Under these circumstances, the odds of life ever evolving would be pretty small.

Which city is the center of the world?
