A creationist is having trouble comprehending the finer points of Relativity!? Gee, what are the odds?

You can use drugs to dilate your mind.
You can use a Taylor Series to dilate a mathematical function. You can dilate a claim into an argument. You can dilate the stupidity ICANT spews by responding to him.

If there was non-existence how did existence begin to exist.
Two half-existences combined to make a whole one.

I just thought of something. ICANT, are you being deliberately obtuse.... Ding! Ding! Ding! Ding! Ding! You hadn't realized this yet? I think I find out over a year ago...

So he's not really this stupid but he is pulling our leg? He's playing dumb and banking on you not fullfilling his unreasonable requests (but still, he's not really that smart). Recall that he loves to claim that he's been posting something here for X-timeframe and nobody has shown where he's wrong yet. When they do show he's wrong, he backs up the goalpost a bit and plays dumb like he doesn't understand why he's already refuted.
The least he could have done is to put a smiley face in there. No, no, no. That would break the illusion of sincerity and then he wouldn't get replies to defend himself against.
Unless your saying he is deliberately lying being intellectually dishonest and an insufferable troll. Sort of, but not really. ICANT is *old*. He's happy with just tricking himself into maintaining the beliefs he's always had. (recall that he loves to claim that he figured this thing out when he was a kid and nobody's proved him wrong yet). He doesn't expect to convince anyone else, he just wants his position to be able to withstand any attack. If that means playing dumb to avoid a direct refutation then so be it.
He gets his jollies from appearing to all the world to be as dumb as a stump? I figured this all out while debating my grandfather at his kitchen table. When its his turn to make a point, everybody better shut up and listen to him because its serious business and he has something important to say. When its your turn to make your point, its all fun and games and he jokes about whatever your saying and doesn't really pay attention much. Especially if its going to show he's wrong or make him rethink something. Its the same tactic ICANT uses.
Why would anyone do this? Does the man have no pride? He does it to reinforce his beliefs. He's already got them a priori, now he'll put them up against the onslaught and when they survive and nobody's proved him wrong (because of the dishonesty he employs), then he can remain victorious and feel comfortible in holding a belief that he hasn't seen refuted yet in all these years

Because our universe is behaving exactly like water bubbles in a current. Not really. How so? Simply on a superficial level? You're really stretching on this one....

If you are driving down the road and shine a laser beam perpendicularly out of the side window, do you really excect the beam to curve backwards a little bit because you're moving forward!?
Or can you realize that the laser beam will remain perfectly straight? Now if you had a dector on a pole...

Is Newton's first law which is
quote:incorporated and operational in postulate #1 of SR? If so what external force do you apply to cause the pulse to travel at an angle? Photons are not objects, they don't have rest mass, and are not subject to this law. The detector cannot move relative to the car because its attached to it. But yes, the thought you're having of the light moving at an angle should help. Since its an angle, its going to have to travel a longer distance than a perpindicular line. Now, Velocity is distance over time. Since the distance is longer, and the velocity must remain constant, then the time component has to become larger. That is time-dilation.

So the pulse will travel in a straight line path from the point it was emitted which will be 2 feet from the pole when the pulse reaches the 4 foot height the detector is from the roof of the car. Therefore the pulse will miss the detector. So that's your hypothesis. Now when you actually test it and you find that the puls *IS* hitting the detector, how are you going to explain your results? You gonna have to use time dilation.

Just to be clear, despite being massless, photons do have momentum and changing a photons momentum does require force. How can something without mass have momentum? Heh, just add some mentum to it and there you go... Mo'-mentum. But seriously...
What is going on here is that ICANT is still struggling to understand... I'm sorry you believe that. I don't think that's what's going on at all. Relish the fact that the lurkers are benefiting so that when you realize that ICANT is playing a game here and has no intention of learning then you won't be so let down.
Within a given reference frame, the photon does not change direction. Yeah, he seems to think that if you fire a laser out of your car window, then its going to curve off towards behind you. But that's just because he's caught himself up. He's not honest so I doubt he really thinks much of this stuff. I've debated him in the past... he's really old and stubborn and dishonest.

You claim the pulse will not hit the D but will hit the S instead so please explain how the pulse changes directions, when it is emitted pointed at D. The reference frame is moving.

Catholic Scientist writes: The reference frame is moving. Which reference frame is that? The drivers reference frame inside the car? Yup!

The drivers reference frame inside the car is moving relative to what? Everything else that is not within its reference frame.
That reference frame resides inside the car's reference frame and is at rest relative to the car's frame of reference. And so are the laser and the detector. They are all motionless within the cars reference frame.
According to the laws of inertial that pulse must travel in a straight line from the point emitted in the direction the laser pen was pointed when the pulse was emitted. Within a reference frame... that's the part you're not getting. And the laser and detector are not moving within the cars reference frame. Its only when you have an observer in the reference frame of the ground, when they're watching the car go by and the laser beam hitting the detector, that we start to see any wierdness.
The direction that pulse is traveling can not be changed unless acted upon by an unbalanced force. Within the cars reference frame, there's no need for force because nothing is moving.
Now if you know of some unbalanced force that acts upon the pulse to change it's direction after it is emitted to cause it to hit the S please present that force and it's source. Think it through just a little bit further... If the car moving across the salt flats means that the laser will miss the detector, then the fact that the earth is moving through the milky way would mean the same thing. Hell, I shouldn't even be able to read this monitor in front of me because we're both flying through the universe at millions of miles per hour! Why do you think that isn't happening?

I can't figure out how to draw the inside of the car with the tools I have. It would just look like this: Y| | | | D Niether the laser nor the detector are moving within this reference frame.

Niether the laser nor the detector are moving within this reference frame.
Not quite. I think your answer is based on the old experiment. You are responding to a thought experiment where sensor S and detector D are both mounted on the tracks. Oh, I didn't realize it was a different experiment. Whoops.
But you are right about the central issue here. You don't need to show the interior of a car to show the driver's reference frame. A simple X/Y coordinate drawing is all that you need. You can use the same drawing to show either the car's reference frame or the driver's reference frame. This little animation that Taq provided us with is great!: http://einstein.byu.edu/~masong/htmstuff/Clock2.html
