Dark Matter

In one of the English sections of my SAT test, critical answer questions were taken from a passage about dark matter. In case you don’t know what dark matter is, it is a form of matter in the universe that exists in space and not much is known about it. Personally, I had never heard of dark matter before taking the SAT, but the small amount that I read about it was very interesting and compelling. From what I remember of the passage and from a small amount of research,  scientists have reason to believe dark matter exists based on something to do with the stars. It’s too confusing for me to fully understand to where I can explain it, and honestly scientists don’t understand it fully either; currently dark matter is still a theory. According to nasa.gov, “We are much more certain what dark matter is not than we are what it is. First, it is dark, meaning that it is not in the form of stars and planets that we see.”

Here is the link to that article: http://science.nasa.gov/astrophysics/focus-areas/what-is-dark-energy/. Anyway, the point is, there is a lot out there about the universe that humans don’t know and every once in a while, a huge discovery is made and the world is never the same. I am just wondering if there really is such a thing as dark matter and if there is, how it might affect our understanding of everything we know.

I am out of school now for the summer so I have time to wonder about such things.
