Match each statement with the correct term.
Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.
This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.

20. The Big Bang says that the universe has not existed forever. It had a distinct beginning about 14 billion years ago called the 'Big Bang'. Therefore light from any object more than 14 billion light years away has not had time to reach us. The other p
