宇宙的“宇”指的是空间；“宙”指的是时间。或者说，宇宙指的是空间和时间

Universe "yu" refers to the space; "universe" refers to the time. Or that the universe is referring to space and time. We then deep-step look at mass-energy conversion formula E = mC ^ 2. If a person in a place where there is no light, he will not see anything, you can not tell the direction, that he lost his sense of space; and asked if he now is day or night, he could not answer, that he also lost his sense of time.

The universe's "space" refers to space; In other words, the universe refers to space and time. Let's take a closer look at the mass-energy conversion formula E-mC-2. If he puts a man in a place with no light at all, he can see nothing and can't tell the direction, which means that he loses his sense of space;

"Universe" of the universe refers to space; "Zeus" refers to time. In other words, the universe refers to space and time. Let's take a step further and look at the mass energy conversion formula e = MC ^ 2. If a person is placed in a place where there is no light at all, he will not be able to see anything and distinguish directions, that is to say, he has lost his sense of space; if he is asked whether it is day or night, he cannot answer, which means that he has lost his sense of time.
