How Large is the Universe? Bigger than you can Imagine?

The universe that we can see is so large that it might as well be infinite. Our little solar system is like a speck of dust by comparison. That part of the universe that we can't see may actually be infinite, but we might never know.

The Challenger Disaster: STS-51-L Helicopter Camera

I recently watched a 4 episode documentary on Netflix about the Challenger disaster.  This event happened at an important time in my life shortly after the death of my father in 1986.  The documentary demonstrates that people knew there was a problem and made poor decisions because they considered the risk to be minor.

I just happened to come across a video on youtube that shows the disaster from a slightly different perspective than what I have seen before.
