Gravity is a function of mass. Every basic mechanics coursedoes the calculation which determines the amount of centrifugal forcedue to the rotations of the earth is s approximately .5% at theequator. Moreover, the gravitational force at the equator is actuallyLESSENED due to the spin of the earth, as it is providing thecentripetal force. Gravity is defined by newton's law of gravitation, that isG*m1*m2/(r^2) where m1 and m2 are the masses of the objects (earth andyour) and r is the distance between their center of masses. G is thegravitational constant, and it is suitably puny (6.67259 x 10E-11 inmetric units...). It has nothing to do with rotation.However! If we were to stop the rotation of the earth about the Sun,then we'd have a different problem: we'd collapse into the Sun's core,and burn up. But that is independent of the earth's axial rotation.Also, the dark side of the earth would like die off due to cold, butthat's irrelevant to the problem.	   ------------------------------------------------	  |        Justin Hahn <jehahn@raven.bu.edu>       |	  |Systems Administrator, Boston University SPI Lab|	   -------------------------------------------------To unsubscribe from this list: send the line "unsubscribe linux-kernel" inthe body of a message to majordomo@vger.rutgers.eduPlease read the FAQ at http://www.tux.org/lkml/`
