Two astronomers accidentally discovered (1:unifrom, 2:background radiation, 3:not uniform, 4:137,000,000 years ago, or 5:13,700,000 years ago), which is evidence of universe expansion that supports the Big Bang theory. This is particularly strong evidence because its temperature is (1:unifrom, 2:background radiation, 3:not uniform, 4:137,000,000 years ago, or 5:13,700,000 years ago). By observing this today, we can see what the universe looked like (1:unifrom, 2:background radiation, 3:not uniform, 4:137,000,000 years ago, or 5:13,700,000 years ago)

Question

Two astronomers accidentally discovered (1:unifrom, 2:background radiation, 3:not uniform, 4:137,000,000 years ago, or 5:13,700,000 years ago), which is evidence of universe expansion that supports the Big Bang theory. This is particularly strong evidence because its temperature is  (1:unifrom, 2:background radiation, 3:not uniform, 4:137,000,000 years ago, or 5:13,700,000 years ago). By observing this today, we can see what the universe looked like (1:unifrom, 2:background radiation, 3:not uniform, 4:137,000,000 years ago, or 5:13,700,000 years ago)

GPT-4o mini · Answer

The correct answers to fill in the blanks are as follows:

Two astronomers accidentally discovered (2: background radiation), which is evidence of universe expansion that supports the Big Bang theory. This is particularly strong evidence because its temperature is (1: uniform). By observing this today, we can see what the universe looked like (5: 13,700,000 years ago).

To summarize:

Background radiation
Uniform temperature
13,700,000 years ago
