内务大臣梅说她只下令对欧洲公民入境英国时放松边检，其中包括同父母一起出游的小孩，这样警卫人员就能把焦点集中于嫌疑更大的入境者。

Moreover, because the universe is so vast, it takes years for a signal travelling at the speed of light to reach only as far as the next star to our sun.

另外，由于宇宙是如此广袤，信号以光速从最近的一颗恒星传到太阳也要花去数年时间。

Light zips along at the actual "speed of light", faster than which nothing can go, only when it is travelling through a vacuum.

只有在真空中，光的速度才能达到真正的“光速”，这是世界上最快的速度。

Because the light is travelling through cables, the new device is much less likely to go out of alignment.

由于光是在电缆中传播，这个新设备的准确性更高。

When you concentrate on the light at the end of the tunnel, you are travelling and visiting different worlds in different dimensions to yours.

紧盯着隧道深处那道光，你就将在不同维的不同世界里穿越。

Since the speed of light is 299, 792, 458 metres per second, the neutrinos were evidently travelling at 299, 798, 454 metres per second.

因为光速是299 792 458米每秒，而中微子的速度是299 798 454米每秒。
