Respecting dimension spends this term, some closer year of frequency that appears it seems that is increasing, let a lot of people that do not catch a cold to physics so, began to discuss physical world, and this should be attributed to Liu Cixin of writer of famous science fiction, his work " 3 body " let Chinese science fiction successfully move toward the world not only, the most important depend on letting a lot of people generate enthusiasm to physical He Yuzhou from now on.
It was mentioned in the novel so called " fall dimension is hit " one word, pass namely in the novel 2 Xiang Bo undertakes dimension is hit falling, the world that spends Gao Wei becomes low dimension to spend, three-dimensional become 2 dimension, the deadliest to a world harm also saying in the novel is to fall dimension blow, put forward with respect to somebody then, is the division skill of our mankind denied prevent this kind to fall is dimension hit? The scientist made a response to this, our world is not a novel, at least 3 kinds of methods can be answered.
Actually this is the solution that mentions inside 3 body, its reason is velocity of light it is the rate of a maximum in the universe, won't any can surmount velocity of light, to falling dimension is hit, we need to overtake velocity of light to be able to escape only the ground of this one death, in fact the scientist also finds the method that overtakes velocity of light already, that is a fast airship, the speed that the scientist discovers to the universe explodes greatly is even faster than velocity of light expand, want to imitate cosmic big burst to made airship go only, although the scientist is at present helpless still, believe future meets what can accomplish nevertheless.
As similar as airship of velocity of light still one kind is called bug hole to pass through, in science fiction film we often see, a few airship cross peculiar " passageway " , when they come out again, had been another space, the scientist had confirmed bug hole exists really nowadays, just the high speed instability as a result of bug hole interior, all material that enter bug hole can be smashed, because this still cannot use bug hole truly at present, at present nevertheless the scientist also is thinking way.
Black region isolation may be very much the person had not heard of, actually this " black " those who point to is a black hole, the scientist passes observation discovery, be in the space all round the black hole is twist actually, as a result of the black hole powerful gravitation place causes this, whether can scientist tentative idea adopt the method that imitates space of black hole twist, will make circuit the defence wall around the earth, can resist so fall dimension was hit, do not pass this project really special huge is.
Human world is mixed from beginning to end the novel is different, in the novel we have a final result only, but in reality our mankind has wisdom, have the capacity of adapt oneself to changing circumstances, although a lot of idea cannot come true at present, but sooner or later we can turn into it reality, this ability is human force.
