How did Hubble change the view of the universe?

• A. He proposed the Big Bang theory
• B. He discovered galaxies beyond the Milky Way
• C. He invented the telescope
• D. He discovered dark matter

Answer: (B)

Hubble fundamentally changed the view of the universe with his discovery of galaxies beyond the Milky Way. Prior to his work in the early 20th century, the prevailing belief was that the Milky Way comprised the entirety of the universe. Through his observations, especially using the Hooker Telescope at the Mount Wilson Observatory, Hubble identified that the Andromeda Nebula and other nebulae were actually separate galaxies, located far outside our own. This revelation led to the understanding that the universe is much larger and more complex than previously thought, containing billions of galaxies. Hubble's work laid the foundation for modern cosmology, including the understanding of the universe's expansion, which he demonstrated through the observation of redshift in distant galaxies. His findings broadened the scope of astronomical research and shifted the paradigm toward a universe filled with diverse and far-flung galaxies, fundamentally altering our perception of the cosmos and humanity's place within it.
