A question about "time"!

More than 60 years ago, Albert Einstein put forward the "wormhole" theory. Wormhole, also known as Einstein-Rosen Bridge, is a narrow tunnel that may exist in the universe and connect two different time and space. Wormholes were put forward by Einstein and Nathan Rosen when they studied the gravitational field equation in the1930s. They thought that wormholes could be used for instantaneous space transfer or time travel. However, its existence has not been confirmed.

As early as 1950s, scientists had studied the "wormhole". Due to the limitation of historical conditions at that time, some physicists thought that the wormhole might be used in theory, but the gravity of the wormhole was too great to destroy everything that entered, so it could not be used for space navigation.

With the development of science and technology, new research has found that the super-strong force field of wormhole can be neutralized by negative mass to stabilize the energy field of wormhole. Scientists believe that antimatter also has a "negative mass" relative to the "positive matter" that produces energy, and can absorb all the energy around it. Like wormholes, "negative mass" was once thought to exist only in theory. However, many laboratories in the world have successfully proved that "negative mass" can exist in the real world and captured a small amount of "negative mass" in space through spacecraft.

According to the calculation of researchers in the Department of Physics of the University of Washington, the "negative mass" can be used to control the "wormhole". They pointed out that "negative mass" can enlarge the original tiny "wormhole" enough for the spacecraft to pass through. Their research results have aroused great interest from the aerospace departments of various countries, and many countries are considering funding the research of "wormholes", hoping that "wormholes" can be really used for space navigation.

Astronauts believe that although the research on "wormhole" has just started, its potential return can not be ignored. Scientists believe that if the research is successful, human beings may need to re-evaluate their role and position in the universe. Now that human beings are "trapped" on the earth, it takes hundreds of years to sail to the nearest galaxy, which is impossible for human beings at present. However, in the future space navigation, if a "wormhole" is used, it can reach distant places in the universe in an instant.

According to scientists' observation, the universe is full of millions of "wormholes", but few of them are more than 65438+ million kilometers in diameter, and this width is the minimum requirement for the safe navigation of spacecraft. The discovery of "negative mass" has created new opportunities for the utilization of "wormholes", which can be used to expand and stabilize tiny "wormholes".

Scientists pointed out that if the "negative mass" is transferred to the "wormhole", the "wormhole" is opened, and its structure is strengthened and stabilized, the spacecraft can pass.

The concept of wormhole originated from the study of Schwarzschild's solution. When analyzing the white hole solution, physicists found that the space-time of the universe itself could not be flat through an Albert Einstein thought experiment. If a star forms a black hole, then space-time is perpendicular to the original space-time at the schwarzschild radius, that is, at the horizon. In the uneven space-time of the universe, this structure means that one part of the black hole horizon will combine with another part of the universe, and then a hole will be created there. This hole can be a black hole or a white hole. This curved horizon is called Swansea throat, which is a special wormhole.

Physicists have been interested in the properties of wormholes since they were discovered in Schwarzenegger's solution.

Wormholes connect black holes and white holes and transfer substances between them. Here, the wormhole becomes an Albert Einstein-Rosen bridge, and the matter is completely decomposed into elementary particles at the singularity of the black hole, and then transmitted to the white hole and radiated through this wormhole (that is, the Albert Einstein-Rosen bridge).

Wormholes can also appear in the normal space-time of the universe and become sudden hyperspace pipes.

Wormholes have no horizon, only an interface with the outside world, and wormholes are connected in time and space through this interface. The interface between wormhole, black hole and white hole is a space-time pipeline and the connection of two closed space-time regions, where the curvature of space-time is not infinite, so we can safely pass through wormhole without being destroyed by huge gravity. The wormhole derived from theory has many characteristics, which are not detailed here due to the limitation of space.

There are several versions of wormholes.

One is a tunnel of space, just like a ball. If you want to walk along the sphere, it will be far away. But if you follow a diameter in the ball, the wormhole is this diameter.

The second is the connection between black holes and white holes.

Third, you said just visiting. According to Einstein, you can travel in time, but you can only watch it, just like watching a movie, but you can't change what happened, because time is a line and events end one after another. You can't change the beads or adjust the order.
