First of all, what does a wormhole look like? 1935, Einstein and his good friend, American Israeli physicist Nathan? When Rosen studied the gravitational field equation, he found that there could theoretically be a shortcut to connect two distant places in the universe. Just like the two ends of a mountain can be connected by a tunnel.
Simply put, in a two-dimensional plane, the straight line between two points is the shortest, but when you fold the paper, the two points on the paper are coincident. It will be found that the coincidence of two points is the shortest in three-dimensional space. Wormholes are the same theory, so if we master the space wormhole technology, then human beings can reach every corner of the universe.
Second, how to cross the wormhole. Trying to cross a wormhole is not as simple as imagined, but also full of danger and unknowns. According to Einstein's theory, if you want to cross a wormhole, you should generally stabilize it first, because the space inside the wormhole is distorted, and even time may be distorted. Therefore, if you want to cross the wormhole, you must first have enough negative energy density materials to support it. Otherwise, when human beings cross the wormhole, the strong tearing force is likely to directly crush human beings. Of course, all this is only speculation so far. Because so far, no one has crossed the wormhole, and no one can make a wormhole to do experiments. At present, human beings are still in the first-class civilization, and can only manipulate the energy of the earth, and even solar energy cannot be completely controlled. The universe is still an unknown world for human beings, and it is still waiting for human exploration.
