现在，出名的公式E ＝ mc2 时常被误解如惯性质量和每个类型的能源之间的无条件的同等（也就是，m ＝E／c2）. 一般显示，依照爱因斯坦的一般相对论，一个如此要求是不正确的。 这一个问题的根由于特别的相对论的不充分的理解是生产出名的公式E ＝ m c2，如同爱因斯坦澄清的，以能量保护一定被了解一样。 举例来说， Reissner－ Nordstrom 度规的举例说明电磁的能源实际上会生产排斥性的引力。 而且，这个非同等是本质的在电磁中, 并且大体上与相对论中详细的计算无关。 一个如此排斥性引力的实验确认被计画。 协同地，一般指出这是Will的书的一个主要的错误，那书"引力的物理学的理论和实验"被物理评论，自然，和科学考虑如无价的。
Currently, the famous formula E = mc2 is often misinterpreted as the unconditional equivalence between inertial mass and each type of energy (i.e., m = E/c2). It is shown that, according to Einstein’s general relativity, such a claim is incorrect. The root of this problem is due to an inadequate understanding of special relativity that produced the famous equation E = m c2 that, as Einstein clarified, must be understood in terms of energy conservation. For example, the Reissner-Nordstrom metric illustrated that electromagnetic energy actually would produce repulsive gravity. Moreover, this non-equivalence is intrinsic in electromagnetism and is independent of the detailed calculations in general relativity. Experimental verification of such a repulsive gravity is proposed. Concurrently, it is pointed out that this is a major error in Will’s book, “Theory and experiment in gravitational physics,” that the Physical Review, Nature and Science considered as invaluable. ※※※※※※ 刘武青 |
