Most of us have a
pretty good understanding of the basic timeline of our universe. Sometime,
around 13.8 billion years ago, there was a BANG, and our universe came into
being. A few years passed and, roughly 13.6 billion years ago, the first stars
were born. Our own little solar system came about 4.5 billion years ago, and
evidence suggests that life arose around 3.5 billion years ago. Moving on to
humanity, historians assert that civilization formed in various “cradles”
sometime around 3300 BCE. Time passed in much the same way and, eventually, I
typed this little article and (hopefully) you read some of it. But where are we
headed from here? What does the end of everything have in store for us? Photograph
