The two correct answers are:
1. It was extremely hot.
2. It was very tiny.
The evidence supporting the Big Bang theory assumes that two things were true about the universe when it began:
1. It was extremely hot: The theory suggests that the universe originated from a singularity, an extremely dense and hot state. As the universe expanded, it cooled down over time.
2. It was very tiny: The theory suggests that the universe started from a highly compact and dense state known as a singularity. This means that the universe was initially very small in size before undergoing rapid expansion.
So, the correct answers are:
- It was extremely hot.
- It was very tiny.
