按照当时我们所相信的定律,一个热体必须在所有的频段同等地发出电磁波(诸如无线电波、可见光或X射线)。例如,一个热体在1万亿赫兹到2万亿赫兹频率之间发出和在2万亿赫兹到3万亿赫兹频率之间同样能量的波。而既然波的频谱是无限的,这意味着辐射出的总能量必须是无限的。
他的计算结果是根据超高能量和量子引力物理学的假设。
His calculations relied on assumptions about the physics of ultra-high energies and quantum gravity.
只不过圈量子引力理论把空间分为微小的“构建模块”,而CDT假设空间-时间不是分成微小的构建模块—而是叫做pentachorons的四维的小块。
Just as loop quantum gravity breaks up space into tiny "building blocks", CDT assumes that space-time is split into tiny building blocks - this time, four-dimensional chunks called pentachorons.
这就是说,研究环圈量子重力学的理论学家认为无需先作出时空的几何假设,便能表述自然定律。
This means that theorists working on it believe the laws of nature can be stated without making any prior assumptions about the geometry of space and time.
