Question

which of hubbles findings supported the big bang theory? check all that apply. galaxies that are closest to ours are moving more quickly than those located farther away. galaxies tend to move toward each other. there are billions of galaxies in the universe, not just one. the universe formed from a central point. most galaxies in the universe are moving away from earth.

Explanation:

• Hubble's law states that the velocity at which a galaxy is moving away from us is proportional to its distance. So, galaxies farther away are moving faster (not closer ones moving faster as in the first option).
• Galaxies are moving away from each other (not toward each other as in the second option) as the universe is expanding.
• The fact that there are many galaxies (third option) is a general observation about the universe's structure but not a direct support for the Big - Bang theory which is about the origin and expansion of the universe.
• The Big - Bang theory posits that the universe started from a singularity (a central point), but this was a theoretical concept at the time of Hubble's work and not directly an observation by Hubble.
• Hubble observed that most galaxies are moving away from Earth (red - shift phenomenon), which is a key observation supporting the idea of an expanding universe (a major aspect of the Big - Bang theory).

Answer:

Most galaxies in the universe are moving away from Earth.
