First, claiming, "I used length contraction to generate the paradox. I didn’t need anything else," is absurd. Yes, you can create a superficial paradox with length contraction, but resolving it requires simultaneity. Without simultaneity, you have no way to compare events across frames. Length contraction alone doesn’t explain why the car "fits" in one frame and not in another—it just sets up the conditions for the disagreement. Ignoring simultaneity while patting yourself on the back for creating a paradox is like setting a house on fire and claiming you invented arson. Second, your repeated claim, "I’ve stated many times that simultaneity is necessary for frame comparisons," is nothing more than a smokescreen. You say you "accept" simultaneity but treat it like an afterthought—a nuisance you begrudgingly admit exists while refusing to let it do the heavy lifting that relativity demands. The paradox doesn’t just involve "frame comparisons"—it fundamentally hinges on simultaneity to define whether the car fits in a given frame. Length contraction without simultaneity is meaningless. You know this, but you keep pretending otherwise. Now, to your question about simultaneous endpoints for a car that "doesn’t fit." This is where you’re either trolling or genuinely lost. Simultaneous endpoints are always frame-dependent. In the garage frame, if the car fits, the endpoints align with the entrance and exit simultaneously. In the car frame, the endpoints cannot be simultaneous in the same way because of the relativity of simultaneity. This isn’t a hard concept to grasp—unless, of course, you’re trying to muddy the waters for fun. Your final jab, "If endpoints can be simultaneous for a car that doesn’t fit, how can they define fitting?" is yet another transparent dodge. Endpoints define fitting within a specific frame. If you refuse to acknowledge that simultaneity is frame-dependent, then of course you’ll keep spinning your wheels on this question. But that’s not a failure of relativity—it’s a failure of your understanding. You’re not engaging with the physics; you’re playing word games to avoid admitting your argument is flawed. If you want to continue this debate, at least do the bare minimum of accepting that simultaneity is not optional or secondary—it’s the cornerstone of the resolution. Until then, your "facts" are just noise. -- > You received this message because you are subscribed to the Google Groups > "Everything List" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to [email protected]. > To view this discussion visit > https://groups.google.com/d/msgid/everything-list/00670205-f566-417f-a772-79eeeb6b87fcn%40googlegroups.com > <https://groups.google.com/d/msgid/everything-list/00670205-f566-417f-a772-79eeeb6b87fcn%40googlegroups.com?utm_medium=email&utm_source=footer> > . > -- You received this message because you are subscribed to the Google Groups "Everything List" group.
