Yes, Indeed! Einstein says “If you can’t simply explain it, you haven’t understood it well enough”. I am very fond of giving lectures to my classmates about these theories and often i don’t have much a grip on one specific topic and while explaining it, it becomes more insightful to you and you can think of it as a whole new idea and that is when one finds inner peace”

That’s a pretty easy thing to imagine. Imagine that the earth is still in the center of the solar system. Sun ans other planets revolve around the earth the there should be day in half region of earth for a significant period of time i.e like half a year (if this hypothetical orbit is round). If its is so then the rising and setting must not be around us. And it is impossible for the earth to revolve if it is not influenced by the gravitational force!
