Okay, to give a little contextual background, for one of my units we have been given an abandoned town in south-west queensland (AU). It was inhabited by the natives for a while, then Australia was colonised, now no one lives there and there's a few garbagety buildings that are falling apart...

my friend posted this on another forum, and one of the replies he got was that time is continuous, not discrete, I've come across the term before and i think i sort of get it but if someone could clarify what he means, that would be great =D

i think what you said is right, but then it raises a few more questions so having already established it crosses it at some point, the questions is, where? brain-ache :P

i wouldn't say it has nothing whatsoever to do with the problem stated two bodies, the car and the train, both moving with a constant speed, two things being launched off the object, the ball, and the light (if were treating light an a particle) and when you answered it you answered it as if...

i thought of that myself, and it seems like the most probable answer, so what your saying is that it passes through all those points, but in the finite amount of time that it takes to raise the temperature of the object, so it must, then, cross the boundary at some point?

Doc Al, i was talking theoretically, but since your going to be like that whos going to stand ontop of a train traveling at 50mph anyway, and then pitch a ball at exactly the same speed as the train, not to mention the headwind and everything else that is wrong with the question so let's say...

Yeah its like pi is infinate, but when you keep adding digits, it gets closer and closer to the exact answer, but never quite reaches the .99999 was just an example, same thing can be shown with, say 39.1-39.2 passes through 39.11178263 or whatever, there is no limit to it, but it will never...

ouch i feel the brain ache aswell, i still don't really know what waves are, since I've not gotten onto them at school yet :( you still answered the question with some reasoning and logic (Y) rekon you could take a look at my thread, its about two below this one, cheers

ah but relative to an observer, what would you see? assuming you could see it before its gone from sight :P

another riddle is if you were in a car traveling at the speed of light and your turned the headlights on, what would happen? relativity states the speed of light is the same relative to all observers right? so the light can't go at 2c because it can't travel faster than itself, so would you...

Ok I am 16 and the other day my mind started wandering until i started thinking about this, there was no inspiration for it and I've not seen anything like it elsewhere, so tell me what you think :), sofar I've not been able to get a solution for it, I've never done one of these before so I am...
