We used to believe that Newton's law of universal gravitation, which governs the universe, was static, unchanging, and possibly everlasting.
In just a few short years, all of that drastically changed. Newton's gravitation was surpassed by Einstein's General Relativity, which revealed the connection between matter and energy and the structure of spacetime.
His equations implied that the Universe couldn't be static and had to be evolving throughout time, which the discovery of the expanding Universe proved to be the case.
Additionally, his hypothesis foresaw the existence of black holes, which were eventually identified, detected, and even directly imaged.
