There are very industrious experiments being built on Earth -- one called LIGO -- which will detect deviations in the squeezing and stretching of space at less than the fraction of a nucleus of an atom over four kilometers.
そこで人類は地球の表面に 観測装置を作りました そのうちひとつは「LIGO」と呼ばれ 4kmに渡る空間の伸び縮みを 原子核のサイズ以下の正確さで 探知できます
