One invention that Hubble invented was the Hubble Law. In the 1920s, astronomer Edwin Hubble proved how minute and peripheral Earth was in the cosmos.
Hubble built his reputation on the wreckage of rival astronomer Harlow Shapley's famous theory that the entire Universe consisted of the Milky Way galaxy. The invention of the 100-inch Hooker telescope enabled Hubble to prove his theory of the existence of other galaxies. Hubble also discovered that the Universe was expanding, and not static as astronomers had believed.
