Question
_________ are two vital pieces of proof we have for the Big Bang.
ans. red-shift of light, cosmic background radiation and types of elements.
- We have several Universes to compare and study and cosmic background radiation (CBR)
- The large quantity of hydrogen, helium, and lithium found in the Universe and work on epicycles by Ptolemy’s.
- Work on epicycles by Ptolemy and Hubble’s law of expansion of the Universe.
- Hubble’s law of expansion of the Universe and CBR
Hint:
Hubble’s law of expansion of the Universe and CBR are the two vital pieces of proof we have for the Big Bang.
The correct answer is: Hubble’s law of expansion of the Universe and CBR
- Hubble's law helps to understand the movement of particles in the galaxy.
- Edwin Hubble discovered that the universe is expanding with respect to the particles moving away.
- Hubble's law of universe expansion is a piece of evidence for the big bang that states the origin of the universe.
