Lesson 4: Other MaterialsACTIVITY: Big Bang Snap Judgment
Purpose
This activity gives you a chance to get familiar with some of the big ideas related to the Big Bang.
Process
Think about the following statements:
1. We have a sense of what happened during the first few minutes of the Big Bang.
2. The four fundamental forces are gravity, electromagnetism, strong nuclear force, and weak nuclear force.
3. As the Universe expanded, it got hotter.
4. The formation of the first atoms had an effect on the Universe.
5. Cosmic background radiation is compelling evidence that supports the Big Bang theory.
For Further Discussion
In the Questions Area below, list one statement from the list above and say whether you think it is true or false. Since this is a Snap Judgment activity, you don’t have to list evidence. You’ll learn more about these statements later.

- "We have a sense of what happened during the first few minutes of the Big Bang." True, no one was there to see what happened and we can't say we know what happened but we have evidence so we can still say we at least have a sense of what happened.(8 votes)
- Was the Big Bang the "beginning of time" or did something preceed it?(2 votes)
- Theoretically, the Big Bang is the very beginning of time and there was technically nothing before it. However, if you believe in the multiverse theory, you can say that other universes began before ours.(2 votes)
- Is this what we have any evidence of?(1 vote)
- This is from space(dot)com
Scientists have discovered a predicted thermal imprint of the Big Bang, the universe-pervading cosmic microwave background radiation. And we don't see any objects obviously older than 13.7 billion years, suggesting that our universe came into being around that time.(2 votes)
- We have a sense of what happened during the first few minutes of the Big Bang. This statement, is true. Over the years astrologists, with the new technology and innovative ideas, have realized interesting concepts, which have evidence that can let us think they are true.(1 vote)
- "The four fundamental forces are gravity, electromagnetism, weak nuclear force, and strong nuclear force" True, they are known as fundamental because they alone are responsible for all observations of forces in nature.(1 vote)
- "As the Universe expanded, it got hotter." This is false, because the hot environments reparts in the new space as it gets bigger, this means if we have one known hot mass and it expands with the universe is not that concentrated.(1 vote)
- 3. As the Universe expanded, it got hotter.
False because if something hot grow a ton, then the heat would need to spread out. there would not be enough heat for something that's size we don't even know yet.(1 vote) - The four fundamental forces are gravity, electromagnetism, strong nuclear force, and weak nuclear force. True, these are the 4 fundamental forces.(1 vote)
- "We have a sense of what happened during the first few minutes of the Big Bang". True, because scientist already have an idea about it but not extremly precised.(1 vote)
- 4.
True. I don't think I even need to explain.(1 vote)
