That's referred to as Time Dilation...According to Einstein's theory...Time speeds up or slows down depending on how fast you move...!
BTW...the faster one moves the slower time elapses...(not the other way around)
Good observation...plus we have a body that possesses the dexterity to fashion tools and change our environment accordingly. I understand that a porpoise is extremely intelligent, but it cannot fashion a Swiss watch or build a medieval castle.There's a lot more to think about than this weekend's weather or what the Kardashians (sp) are up to. It's that 'thinking OOB' that got us out of caves and into farming among other thing that 'mushrooms on Mars' aren't doing lately.
