In the past few centuries, the subduction zone off the coast of Sendai has generated earthquakes of up to magnitude 8 or so, but nothing as powerful as a 9, which releases 30 times more energy.

在过去的几个世纪里，仙台沿海地区的俯冲带发生的地震震级最大才达到8级，从未达到过9级，而这次地震释放的能量是8级地震的30倍。

The theories of particle physics predict the strength of dark energy to be about 120 orders of magnitude larger than what is observed, and general relativity cannot explain this enormous discrepancy.

粒子物理学理论预言暗能量的强度要比观测到的大约大120个数量级，而广义相对论不能解释这个巨大的差异。

Quantum calculations, however, predict that the amount of vacuum energy in the universe should be more than a hundred orders of magnitude greater than has been observed.

然而，量子计算预示着宇宙中总真空能量应比已被观测到的能量高出一百多个数量级。
