At some point in the future you may ask yourself this question, “How can gravity pull harder (put more force on some things, like bowling balls) and yet accelerate all things equally?”

  1. Yes if our sun became a black hole (which it can’t ever do because it doesn’t have enough mass), we would lose all our sunlight and probably not last very long.

  2. Karen Daley says:

    Karis asks: If the sun turned into a black hole, would the earth become dark all the time? And would it be radiating the same amount of energy as before?

  3. I think there’s a miscommunication in there… let me see if I can help. One day far in the future, the sun will run out of fuel (hydrogen), then the core will collapse, which causes the core to heat up and get denser. The sun will grow into a red giant and expand past the orbits of Mercury, Venus, and the Earth (we think). During this red giant stage, it’s got helium at its core, which it is using for fuel and transforming into carbon. Once the helium runs out, the sun will blow off the outer atmosphere layers revealing a central carbon core, which is an earth-size diamond. This is a white dwarf, and when it cools, it will be the same low temperature as the rest of the universe and become a black diamond.

  4. I have read that what happens when the sun runs out of fuel is that it turns into a super nova. One of your practice tests says the answer is that it turns into a hard black diamond. Can you tell me why the answer you provide is different from a Super Nova?
