思想实验：在卧室里测量地球的周长
1 分•作者: richardjennings•7 个月前
我想通过卧室的窗户测量地球的周长，而且不需要任何人的帮助。
尽管我尝试了很多次，但如果不先测量一段距离，我就无法确定周长。请告诉我，是否有可能不通过测量就能知道周长。
如果无法明确测量周长，但可以知道轨道角度等数值，那么周长的现实对我来说就处于一种叠加态，对我来说它没有实际意义。
如果我没有使用科学进行测量，我就不存在于经典现实中，而是存在于量子现实中。在没有推导出任何数字的情况下（例如，忙于玩电脑游戏），我如何量化相对论如何应用于我？显然它确实适用，但没有测量这些量。
如果我没有存在于经典现实中，因为我从未测量过任何东西，那么我就不必接受了解周围系统的一切会导致一个确定的结果，我可以相信一个预定的结果不适用。潜在的确定性结果取决于我做出测量的决定。
从我试图在卧室测量地球周长的过程中，我得出结论：经典物理学是科学（测量）的结果，而不是关于现实的根本真理。我确定，通过测量而固定的结果是我决定进行测量的结果，由此我确定我拥有自由意志。

I want to measure the circumference of the Earth by looking out of my bedroom window without having to ask for anyones help.<p>As much as I have tried, I cannot realise the circumference without first measuring a distance. Please tell me if this is not the case somehow.<p>If it is not possible to know the explicit measured circumference, but I can know values such as orbital angles, I find that the reality of the circumference is in a superposition relative to myself, it has no actual meaning to me.<p>Without having used science to make measurements, I do not exist in a classical reality, I exist in a quantum one. How can I quantify how relativity applies to me without having derived any numbers (e.g. too busy playing computer games). Clearly it does apply, but the quantities are not measured.<p>If I do not exist in a classical reality because I never measured anything, I do not have to accept that knowing everything about the system around me results in a deterministic outcome, I can have confidence that a predetermined outcome does not apply. Potentially deterministic outcomes are decided by my decision to make measurements.<p>From my attempt to measure the circumference of the Earth from my bedroom I have concluded that Classical Physics is the result of Science (measurements) and not a fundamental truth about reality. I have determined that the outcome that becomes fixed via measurement is the result of my decision to make a measurement and from this I determine that I have free will.
