The Big Bang Theory

2. Term describing the Cosmic Microwave Background as a strong evidence of the Big Bang, observed as an abundant radiance behind celestial bodies.
4. Color often associated with objects moving closer to us, in contrast to redshift of objects moving away.
5. This force played a crucial role in forming denser spots, leading to the creation of galaxies.
7. The Big Bang Theory suggests that the universe was once in this state, as opposed to expanded.
9. The measure of galaxies' movement speed, which notably rises with their distance from us.
12. The uniform quality of cosmic microwave background radiation, indicative of the early universe's cooling phase.
13. This theory describes the universe's origin from a hot, dense state and its subsequent expansion.

1. Initially mistaken by Penzias and Wilson for urban disturbance, this turned out to be a groundbreaking cosmic discovery.
3. These large celestial bodies were formed when the universe got bigger, according to the Big Bang theory.
6. The phenomenon observed when distant galaxies move away, supporting the universe's expansion.
8. The Big Bang theory implies that the universe is constantly doing this.
10. This color is observed in light from objects moving away from us, indicating the expansion of the universe
11. Names of the two scientists who discovered the Cosmic Microwave Background.
