... We haven't learned the last one yet, but it will be important later. Alex's research team has used this fact to show that the universe is expanding faster and faster, rather than slowing down as initially expected. Supernovae are extraordinarily energetic events. This next exercise will allow us to ...

Homework #3 Solutions
... What do we conclude if a planet has few impact craters of any size? If we do not see many impact craters of any size, then there must be some sort of geological process erasing the craters (c). All of the bodies in our solar system underwent a period of heavy bombardment early in their formation – s ...
