Who gave the expanding universe hypothesis?

Correct option is C

The correct answer is (c) Edwin Hubble

• The expanding universe hypothesis was first proposed by Edwin Hubble.

• In 1929, Hubble discovered that galaxies were moving away from each other, and their redshift indicated that the universe itself was expanding.

• This discovery laid the foundation for what is now known as the Big Bang Theory and changed our understanding of the cosmos.

• Hubble’s work is considered one of the most significant contributions to the field of cosmology.

Information Booster:
• Hubble's Law states that the velocity at which a galaxy recedes from us is proportional to its distance from us, which supports the idea of an expanding universe.
• His discovery was made through observations with the Mount Wilson Observatory's 100-inch telescope.
• James Clerk Maxwell contributed to electromagnetism and the theory of light, not the expanding universe.
• C.V. Raman is known for his discovery of the Raman Effect in light scattering, not for contributions to cosmology.
• Galileo Galilei made significant contributions to astronomy, such as improving the telescope, but did not propose the expanding universe hypothesis.

Additional Information:
• Hubble's work led to the understanding that the universe is not static, as previously thought, but rather expanding. This is a key element of modern cosmology.
• The discovery of the cosmic microwave background radiation later provided further evidence for the expanding universe and the Big Bang Theory.
