7 General Theory of Relativity
Advertisement
The general theory of relativity helps us generalize the theory of special relativity and the Newton’s law of universal gravitation. In layman’s terms, it helps us understand gravity as a geometric function of space and time. The Einstein field equations help us better understand the energy and momentum possessed by matter or by radiation, related to the curvature of space and time. In the broader aspect, it helps us understand how the universe is an ever-expanding dimension, and also the nature of existence of its polar opposite, the black hole.

8 Heliocentrism

Heliocentrism was the thorn on the side of flat-Earth believers, who also perpetrated the belief that the Earth is in the center and everything else in the system revolved around it. Copernicus debunked the myth of “geo-centrism” by stating that the in the astronomical schemes, the Earth gravitates around the sun as the central star of the system. This theory was later on contributed to by Johannes Kepler and Galileo Galilei, with observations about other celestial bodies accompanying the Earth in gravitating around the Sun.
