Any Carl Sagan fan knows you're made of star stuff. Protons don't decay into any other particles (as far as we can tell), so you can reliably assume that most bits of you have been around since a second after the Big Bang. But if you're thinking a little more locally, you might wonder whether the Milky Way formed in its entirety before little ol' you were made.

Predicting the future is near impossible -- but that doesn‘t stop us all from having a red hot go. Human beings have been predicting the future since the beginning of history and the results range from the hilarious to the downright uncanny.

One thing all future predictions have in common: they‘re rooted in our current understanding of how the world works. It‘s difficult to escape that mindset. We have no idea how technology will evolve, so our ideas are connected to the technology of today.
