+4 Time as we think of it is just really a matter of perspective. If you're thinking about it while considering the few billion years the earth has been around, a century or so seem like absolutely nothing. Now, if you're thinking about it in a "I'm think I'll go drive somewhere with some friends later" way, two or three hours feels like a long time. Switch the situations around, and a few hours sound insignificant while a century sounds like forever, amirite?
