We assumed that the Milky Way galaxy contained all the stars and planets that existed, and that the Universe was fixed and eternal, following Newton’s law of gravity. However, in a matter of decades, our picture of the Universe changed dramatically. Einstein’s General Relativity replaced Newton’s gravity, revealing how matter-and-energy affect the shape of spacetime. His equations also showed that the Universe could not be static, but…
