i was sitting here wondering about something, and I'm not sure, so ill ask.
suppose you take 2 point masses, say 1 kg each, 1 meter apart, and release them. Would they ever reach the speed of light? As they got very close, the [tex]F _{g}[/tex] would near infinity ( [tex] \lim _{distance \rightarrow 0} F_{g} = \infty [/tex] ), which means that it would accelerate at an infinite rate past the speed of light. but, relativity doesn't allow that, and would start reducing the acceleration as the velocity approached c. so, is [tex] \lim _{distance \rightarrow 0} v = c [/tex] (if v is velocity and c is the speed of light)?
