Question:
Which of Hubble’s findings support the big bang theory? Check all that apply.
1)The universe started at a central point.
2)Planetesimals formed in debris disks.
3)Almost all galaxies are moving away from us.
4)The Milky Way is the only galaxy in the universe.
5)The farther away a galaxy is, the faster it is moving away.
Answer:
The following Hubble’s findings supported the big bang theory:
1)The universe started at a central point.
3)Almost all galaxies are moving away from us.
5)The farther away a galaxy is, the faster it is moving away.
Explanation:
After the big bang, the gluon plasma cooled down two trillion degree, after which nucleosynthesis happened by the formation of the nuclei from the primordial protons and neutrons. The fresher debris disks make up the planetary system followed by the protoplanetary disk phase, only when the terrestrial planets finish there growth. The farther away are moving faster because their space is less expanding.
