Astronomy

Today's video is an introductory video someone made about an Astronomy course.

I think this is really cool, and it poses some interesting questions at the end (paraphrasing):
1. How did the Universe begin?
2. Is there an end to the universe?
3. What are black holes?
4. Is there other life out there?

Even though they made their questions so that they would have a rhyming fashion, I actually think these are interesting topics to start looking at. So for the next few weeks, we are going to tackle these.  I'll share my thoughts on the subject and then you can give your own thoughts below!
