What If the Universe Isn't Uniform?

The video discusses the cosmological principle, which posits that the universe is uniform in all directions. It explores the implications if this principle were not true, such as limitations in understanding the universe. Evidence supporting the principle includes the cosmic microwave background and galaxy distribution. However, some studies challenge this principle, suggesting anisotropy in the universe. Ongoing research continues to test these assumptions, emphasizing the importance of questioning even well-established concepts.

What does the cosmological principle suggest about the universe?

• It is constantly changing its fundamental laws.

• It is uniform and homogeneous.

• It has unique laws of physics in different regions.

• It is different in every direction.

Which of the following provides evidence for the cosmological principle?

• The uneven distribution of stars.

• The cosmic microwave background.

• The unique rotation of galaxies.

• The varying speed of light.

What did the Sloan Digital Sky Survey reveal about the universe?

• Galaxies are moving towards a central point.

• Galaxies are distributed similarly on large scales.

• Galaxies are distributed randomly.

• Galaxies have unique properties in different regions.

What did the 2011 study on supernovas suggest about the universe?

• The universe is expanding evenly.

• The universe is expanding unevenly.

• The universe is contracting.

• The universe is static.

What unusual alignment was found in quasars according to the 2014 study?

• They were not rotating at all.

• They were rotating around aligned axes.

• They were rotating in opposite directions.

• They were rotating around random axes.
