quote:Originally posted by another_someoneJust out of idle speculation: could there be a minimum speed of matter?I was thinking that, since we have relativity telling us that nothing can exceed the speed of light, could we also have a converse law that says that things must travel with a minimum speed?If such a minimum speed limit were to exists, its effects could only exist at the quantum level.Would not a minimum speed limit would create an ambiguity in the speed of a particle that would be not by unlike the uncertainty principle?George
quote:Originally posted by heikkiIf light-particles can go that measured light speed and light speed is different in different matter-stuff(water.air.space,glass. etc.) then if exist smaller matter-particles which can go faster than measured light-speed then it can and speed therefore can be 500000km/s or ever faster. But anypath, space-nature matter-contitions make limits also of this speed (distance/time). And then there is maximun speed-limit.
quote:So other ways, minimun speed? If one matter-particle stay on it's place without moving any direction, then it's speed is 0m/s. Distance is 0 and speed is 0m/1s.
quote:Originally posted by RazakI think the uncertanity principal will create problems to mesure such a speed.
V(B) >= V(A) + V(0).
V(C) >= V(B) + V(0) >= V(A) + 2 * V(0)
V(C) <= V(A) - V(0)
V(D) >= V(C) + V(0) >= V(A) + 3 * V(0)
V(D) <= V(A) - V(0)
V(D) >= V(B) + V(0) >= V(A) + 2 * V(0)
V(D) <= V(C) - V(0) <= V(A) - 2 * V(0)
quote:Originally posted by HadrianIs it the object that has the speed or the force that is acting on it?
quote:Originally posted by heikkiBasic question.I have mind to control that speed force. I can acting and control it. But i need ground under my leg, otherwice i cannot do anything.Moon have mind to control and acting that speed force or not?Second basic question.I am object, construction is matter.Moon is object, construction is matter also.If moon dont has mind to control it's speed force then something round of moon control it. Earth-ball, sun-ball, space-matter. Philosophically comes clearly next question. What different has moon than sun or earth-ball or space-matter?
quote:What kind of control were you thinking for the moon?The moon has a fairly constant speed (although, because of its orbit, it also has constant acceleration) – so why would it need active control of its speed?
quote:Originally posted by nexusSpeed has direction, a vector, if you go lower than zero you are going in reverse.

quote:But if you simply think that there is minimum unit of time above zero I don't think there is.
quote:Take some billiard balls(on a frictionless pool table), the cue ball hits another, say the 8 ball, straight on, all the speed gets transfered to the 8 ball.Now have the cue ball hit 8 ball at an angle from the direction you want it to travel, only a fraction of the speed is transfered. Now increase the angle a smaller amount of energy is transferred. And so on, approaching the speed of zero but never getting there.
quote:Originally posted by nexusbut just because something is uncertain does that mean that it can't happen?
