| Quote (Joy @ Feb. 19 2010,15:39) | | Consider gravity as a condition of existence so self-evident that myriad forms of life that evolved in this particular gravity field 'know' it directly without ever having any knowledge or understanding of Newton or Einstein. The squirrel who does such hilarious gymnastics on the far tiny branches of the dogwood outside my window to get at the ripe berries 'knows' all about gravity. The raven that just flew from the garden fence to the top of a tree on top of the knob 'knows' gravity intimately. That gravity even needed quantification in the first place is something only humans could have decided was "important," and only after somebody asked himself 'what' it was and decided to define it. Until then, nobody asked because nobody thought to ask. Gravity just *is*. |
And the guy spinning the outer arm of a large space station knows what gravity is... except it is centripetal acceleration.
