It was contracting
It was very tiny.
It was composed of ice.
It was extremely hot.
The correct answers are:
- It was very tiny.
- It was extremely hot.
To determine which two answers are correct, we need to understand the evidence supporting the Big Bang theory. The Big Bang theory is a widely accepted explanation for the origins of the universe. The evidence for this theory includes observations such as the redshift of galaxies, cosmic microwave background radiation, and the abundance of light elements.
One of the correct answers is "It was extremely hot." According to the Big Bang theory, the early universe was in an extremely hot and dense state. This is supported by the observation of the cosmic microwave background radiation, which is considered the afterglow of the Big Bang.
The other correct answer is "It was very tiny." The evidence supporting the Big Bang theory suggests that the universe began as an incredibly small and dense singularity. This conclusion is based on observations such as the expansion of the universe and the cosmic microwave background radiation.
Consequently, the evidence supporting the Big Bang theory assumes that the universe when it began was extremely hot and very tiny.
The two correct answers are:
- It was very tiny.
- It was extremely hot.
