Active Galaxies and Quasars - Solution
You need to be more careful! You didn't get any of the problems correct.

Galaxy A | 30,000,000 | 0.002 | 15,000,000,000 years |
Galaxy B | 60,000,000 | 0.004 | 15,000,000,000 years |
Galaxy C | 90,000,000 | 0.006 | 15,000,000,000 years |
- What can be said about the velocity that these galaxies are traveling?
- How does this confirm the idea that our universe evolved from a single point in time?
Each galaxy travels at a constant velocity. However, the more distant galaxies are traveling faster.
Each galaxy has been traveling the same amount of time, 15 billion years. This indicates that they came from the same source, thus the Big Bang theory.
