Today, We Know More About The Universe Than Ever Before

Have you ever looked at the stars in the night and wondered what they actually are? Well, if you have, you're not alone. Stars have always held an importance for our people. The nomadic people used the stars to set times for gatherings, pick fruits and even the migration times of the buffalos. Also, we are not the only ones to determine things based on rotationof celestial bodies. Even the planets in our solar system rotate in a certain pattern. Ptolemy used this to theorize that the Earth was the center and everything revolved around it.
