Final answer:

Edwin Hubble's observations revealed that distant galaxies are moving away from Earth at increasing speeds, supporting the concept of an expanding universe.


Explanation:

Edwin Hubble discovered in the 1920s that the universe is expanding by observing that far-away galaxies are moving away from Earth at increasing speeds. This relationship, known as Hubble's Law, indicates that the farther a galaxy is, the faster it is moving away from us, providing evidence for the expansion of the universe.
