The Test and A Part of The Article.

Before the test, I thought I was going to do absolutely terrible, seeing I was out for 3 days straight, so I thought I missed out on some class review that would of helped me during the test. But during the test, I was doing fine, I didn't screw up on too many questions, though I did do some miss clicking on some questions because the touch screen on the chromebooks isn't the best, that or I just have big fingers. I think I did well on the test, I got most of them correct, and the half points really helped out, so I didn't get too many questions entirely wrong. The one problem that I seem to have is that I mixed up the formulas to find density with finding the formulas to find mass or volume.

Now to summarize a part of the article called The 11 Greatest Unanswered Questions of Physics by Eric Haseltine. I'm going to summarize the How did we get here section of the article. It talks about how Astronomers can't go all the way back to the start and see how everything began, but they can make inferences on how it began. It starts out with telling us about the Big Bang (No, not the TV show), and what happened during it. Then it tells us how planets, stars and galaxies were created. They were created by atoms that had cooled, creating gases that created planets and such. It also talks about how gravity helped make stars, which helped make galaxies and planets.
