Imagine if you could take in all of human history in the blink of an eye. Well, from the first steps on the moon to the first steps out of the slime, that's exactly what we are in cosmic terms. But in that short amount of time, we have done quite a bit. If you could travel through time, you could witness the rise and fall of the many species that existed long before we were here. What would you see if you traveled one billion years into the past? Did Earth ever look like a giant slushball? How far back would you have to go to see the first humans? And, are we already going extinct? Would you need to go through a wormhole or perhaps travel faster than the speed of light? Watch as history unfolds in front of your eyes.
