It's like this; you have a car and a *garage, with the car longer than the garage. Can you use SR to make the car fit in the garage? Well, of course. All that's required is to speed the car to a velocity which, from the frame of the car, contracts the garage sufficiently to get it to fit. * That's not even a correct statement of the paradox. You make the car fit the the garage *in the garage frame* by speeding the car up so the car is Lorentz contracted (I really liked the original tank trap version better). * Problem solved, or so it appears. The various self appointed experts and gurus have an allegedly better solution, but ostensibly somewhat more complicated. Instead of considering length contraction of the garage, they apply the disagreement about simultaneity to show the car won't fit from the pov of the car frame, but does fit from the pov of the garage frame. So, as you should be able to comprehend, both methods give the SAME result! So where is the paradox?* * Truly, it resides in the more-or-less unstated assumption, that there exists an OBJECTIVE reality which precludes this result; that the car fits in the garage frame, but doesn't fit in the car frame. * It's not only unstated, it's un-assumed and non-existent. It's no one's version of the paradox...much less "objective reality". Rather it is Grayson's imagined reality. Brent *How about revealing YOUR version of the paradox? Cat got your tongue? AG * I've both explained it and diagrammed it. As Oliver Heaviside said, "I've given you an argument. I'm not obliged to give you an understanding." Brent *When I asked whether there's an objective reality, you denied it -- and in one of your responses here you again denied it -- but it exists and consists of the car fitting in both frames. Maybe you're suffering from Alzheimer's onset. My intuition was correct, or possibly you don't understand English as well as you think. Why would you expect me to study your plots if you showed lack of understanding what a solution would imply?
