[请教] “能量守恒与转化定律”有没有确凿的反例?
能量守恒与转化定律:
能量既不会凭空产生,也不会凭空消失,它只会从一种形式转化为另一种形式,或者从一个物体转移到其它物体,而能量的总量保持不变。
网上说:
能量守恒与转化定律,在“能量”的不同解释下,是一种实际经验的总结。
迄今为止,并没有“完全充分”的科学证实或证明。
大体是说:
能量守恒与转化定律,是从“不完全归纳法”得到的经验性结论。
所以,请问:
“能量守恒与转化定律”,有没有确凿的反例?
上面问题,特指在“孤立系统”里。
在“开放系统”里,能量不守恒是常态。如太阳能,对地球人几乎就是一个“永动机”。

Energy conservation, however, is more than a general rule that persists in its validity. It can be shown to follow mathematically from the uniformity of time. If one moment of time were peculiarly different from any other moment, identical physical phenomena occurring at different moments would require different amounts of energy, so that energy would not be conserved.
