The scientist who discovered that the Universe was expanding was
A
Bill Nye
B
Albert Einstein
C
Edwin Hubble
D
Alfred Wegener
Explanation: 

Detailed explanation-1: -Like the Hubble Space Telescope, Edwin Hubble’s discoveries transformed the frontier of scientific knowledge. His work took us beyond the Milky Way and placed us in an ever-expanding universe with a myriad of galaxies beyond our own.

Detailed explanation-2: -Hubble found Cepheids in several nebulae, including the Andromeda Nebula and Triangulum Nebula. His observations, made in 1924, proved conclusively that these nebulae were much too distant to be part of the Milky Way and were, in fact, entire galaxies outside our own, thus today they are no longer considered nebula.

Detailed explanation-3: -Hubble’s Law basically states that the greater the distance of a galaxy from ours, the faster it recedes. It was proof that the Universe is expanding. It was also the first observational support for a new theory on the origin of the Universe proposed by Georges Lemaitre: the Big Bang.
