Hello all. I've recently had something of an epiphany regarding relativity. One of those moments when things become clear and it all makes sense. However, having not actually performed any of the experiments which may or may not support the whole thing, I have a question. Is there evidence of length contraction? If so, what is it? Are there any alternative explanations for it? Basically it all started making sense in the most amazing way (and it's really far simpler than I had expected), but my understanding of it requires the acceptance of length contraction, which, as I said, I have not personally checked out much.
