Who gave the expanding universe hypothesis?
Show answer & explanation
Correct answer: C
Explanation
Thecorrect answer is option 3 i.e. Edwin Hubble.
The expanding universe hypothesis was first formulated based on the observations of Edwin Hubble in the late 1920s. By studying distant galaxies, Hubble discovered that they were moving away from the Earth, with their speed proportional to their distance—a relationship now known as Hubble’s Law. This implied that the universe itself was expanding. Hubble’s findings provided strong evidence against the previously held idea of a static universe and laid the foundation for the Big Bang theory. His work revolutionized cosmology and our understanding of the universe’s origin and evolution.

CV Raman – An Indian physicist known for the Raman Effect, not related to cosmology or the expanding universe.
-
Galileo Galilei – A pioneer of modern astronomy, but he lived in the 17th century, long before the concept of an expanding universe.
-
James Clerk Maxwell – Known for formulating the electromagnetic theory, not for work on the universe’s expansion.
