Why do virtually all the galaxies in the universe appear to be moving away from our own?

Options:

1. Because we are located near where the Big Bang happened.

2. Because we are located near the center of the universe.

3. Observers in all galaxies observe a similar phenomenon because of the universe's expansion.

Answer:

3. Observers in all galaxies observe a similar phenomenon because of the universe's expansion.

Explanation:

A scientist named Hubble discovered a relationship between two measurable properties of galaxies, their velocities and their distances. According to Hubble's law, the space between galaxies is expanding.

Hubble said that In reality, the galaxies are not really moving through space away from each other. Instead, it is the space between these galaxies that is expanding, as the universe expands, the galaxies get farther from each other, and the apparent velocity will appear to be larger for the more distant galaxies.
