Are our universe's days numbered? Yes and no, depending on how you look at it. Travel as far into the future as possible in a video describing the five ages of the universe. The narrator begins the tale in current days, which are the infancy of the universe, then illustrates its physical transformation to the very end. He also discusses alternate endings, leaving hope for what lies incredibly far ahead.

• This video is hosted on YouTube

Pros

• Presents content in a very organized manner, which makes the video easy to follow despite the difficult topic
