1915年以前、空間と時間は出来事が起こる固定の舞台と考えられていましたが、それ自体が何が起こるかに影響されないものでした。空間と時間は現在、動的な量です... 空間と時間は、宇宙で起こるすべてのことに影響を与えるだけでなく、影響されます。

Before 1915, space and time were thought of as a fixed arena in which events took place, but which was not affected by what happened in it. Space and time are now dynamic quantities... space and time not only affect but are also affected by everything that happens in the universe.
