Okay, so week 4 was really interesting and I feel like we learned a lot of new material which was exciting. But, I guess it's being in this class that has made me a skeptic, because during most of the classes I kept thinking "how do we know?" I mean, especially when it comes to atoms and other really tiny things, we basically just have to trust that all the "tests" and microscopic observations of these scientists are correct. It so tiny! We can't observe that! I thought about atoms in particular when it came to talking about how they are comprised of mostly blank space. How do we know? I know we have Rutherford's test and all of the other "proof" but what IS "blank space?" Air? No. Water? No. What is it? I began to think about that when we zoomed out of our spectrum and started talking about space. SPACE. What is this space? I just don't buy it. I think that it has got to be some other material that we haven't figured out how to process or identify yet. I guess with things past 10 to the -7 and things past 10 to the 2, I don't completely trust the information given to us about them. Maybe my next webpaper will be on this...
