四维时空 [物] four-dimensional spacetime
- 这个问题是针对四维时空来说的。
This problem is specific to four-dimensional spacetime. - 在四维时空中(以鸟的眼光来看),这些粒子的轨迹就像一团纠结的义大利面条。
In four-dimensional spacetime—the bird perspective—these particle trajectories resemble a tangle of spaghetti. - 我们发现了一类胶子链,在四维时空中的行为就和重力子一样,重力子是重力现象的基本量子。
It turns out that one type of gluon chain behaves in the four-dimensional spacetime as the graviton, the fundamental quantum particle of gravity.
