Scientists hold their breath! A great event happened in the Indian constellation, and the entrance to the parallel universe was found.

On March 14, 2007, NASA's Swift Satellite suddenly received a mysterious signal from the Indian constellation1600 million light years away. This is a long burst of gamma rays with a duration of 102 seconds. It is usually found that this long explosion means a supernova explosion, and the large telescope on the ground immediately focuses on the Indian constellation.

How did supernovae form? This gamma-ray burst has been studied for five years. 20 1 1 year, astronomers put forward an incredible possibility: this may be the first white hole observed in human history!

Everyone has only heard of black holes before. So, what is a white hole? White hole is one of the biggest ideas in the universe. If the white hole really exists, it may change the origin of the universe. Up to now, the white hole is still just a constant in Einstein's field equation. This is just a mathematical guess, which has not been discovered by scientists.

So what exactly is a white hole? The simplest explanation is to turn the characteristics of black holes into white holes.

A black hole is a space-time region. Light and matter can enter the black hole, but they cannot leave it. White hole is also a space-time area. Light and matter can never enter this area, but they can radiate from it. Simply put, black holes can't get in and white holes can't get out.

With the continuous improvement of astronomical observation methods, astronomers have found that quasars do not move so fast. Then why is there such a big red shift? Schmidt believes that quasars are too far away from the earth. Tens of billions of light years away, because the universe is accelerating, the farther the galaxy is, the greater the red shift is. If you subtract the expansion speed of the universe, the moving speed of quasars is not so scary.

However, this discovery is even more confusing. Galaxies can usually be seen as far away as10 billion light years. A dot represents a galaxy, but this quasar can emit light that a galaxy can emit. For example, our Milky Way is a very common galaxy in the universe, containing 200 billion stars. Now a quasar emits 200 billion stars, which is incredible!

When a black hole passes through the interstellar matter cloud, it will attract matter inward, and in the process, it will emit powerful gamma rays; Or a black hole tearing a star will produce millions of times the light of the star. So quasars are actually a phenomenon produced by black holes swallowing matter.

1964, the cosmologist Igor Novikov of the former Soviet Union suddenly put forward a brand-new concept "white hole" and further put forward a scientific conjecture: Will quasars be white holes instead of black holes?

Novikov's theory has attracted many scholars' research. But this idea was a bit too advanced at the time. The main reason is that this theory is not supported by astronomical observations.

After 16 years of observation, astronomers confirmed that Sagittarius A is a huge black hole, with a diameter equivalent to 3 1.5 times that of the sun and a mass equivalent to 465,438+millions of suns, but for the dust cloud covering the center of the Milky Way. Sagittarius A will be brighter than the moon. Every night, we will see a huge fireball in the center of the Milky Way, becoming the brightest celestial crystal in the night sky.

So, is it possible that quasars are white holes? Because it does conform to a feature of white holes, that is, it ejects substances outward. At present, the giant black hole of Sagittarius A star is devouring a small black hole, which scientists have observed. Scientists believe that there is a quasar produced by the merger of black holes, which ejects huge amounts of gas, dust clouds and plasma rays. This shows that the black hole not only can't get in and out, but also ejects outward in the process of swallowing, so the black hole also has the characteristics of a white hole.

This discovery is shocking! The theory that matter falling into a black hole can bounce back from a white hole is very important, which shows that black holes and white holes are probably interchangeable. This photo taken by scientists in recent years shows this spectacular cosmic phenomenon.

The red part of the photo hides a black hole, while the white halo is a galaxy named NGc54 1 with many newborn stars in the middle. This photo reveals that the birth of galaxies and stars may be related to a large amount of matter ejected by black holes, and reveals the theory that the matter that began to subvert the past universe originated from BIGBANG.

Since black holes and white holes can be converted to each other, the question now is: where is the substance sucked by black holes? Where does the substance of the white hole come from? Through what are they interrelated and transformed?

Next, we will introduce the most interesting part. As early as 1930, Einstein and his colleague nathan rosen discovered a strange phenomenon when they were studying the gravitational field equation. There seems to be a wormhole in the universe. This scientific hypothesis is called Einstein-Rosen Bridge.

Because there were no concepts of black holes and white holes at that time, people didn't know what was on both sides of the bridge.

This picture divides space-time into four regions. One and four represent two isolated universes, two represent black holes and three represent white holes, and the connection point in the middle is called Schwarzschild throat. The Einstein-Rosen Bridge connects a universe, and the matter swallowed by a black hole will be spit out from another universe by a white hole.

Some friends will say that if black holes and white holes are responsible for material handling in the universe, are there so many black holes? In the total volume of Hubble, there are about 40 trillion black holes. In our hometown alone, there are more than 65438+ billion black holes in the Milky Way. So the world we live in may have countless parallel universes, and the universes cannot communicate with each other.

The universe is completely isolated, just like cells have cell membranes. However, water and many substances can be exchanged through the cell membrane, which is produced under the action of tissue fluid. Because there is a concentration difference between the liquids at both ends of the cell, the liquid with high concentration will spread to the direction with low concentration. Gravity is like interstitial fluid all over the universe, or to put it another way, all universes are immersed in the gravitational field. The gravitational difference of this universe will promote the material exchange between universes, and black holes and white holes are special channels for material exchange.

Black holes are matter shredders. After entering a black hole, all matter will be squeezed into elementary particles at the starting point, and then ejected from a white hole, just like a rag shredder. Of course, we don't want to turn into rags and be sprayed out. What we want to do is to let people drive the spaceship through the wormhole alive, otherwise it is meaningless.

The connection between black holes and white holes may be the past and the future. If we enter a black hole, there is a way not to be sucked in by the singularity, and it is time to witness history.

We just need to stay in the black hole for a short time. When a black hole becomes a white hole, we will suddenly be spit out by the white hole. This time, it is likely to change the world upside down. When we look up, maybe the Milky Way has merged with Andromeda. It's been 3 billion years, and the whole universe looks different. This is called "one day in the hole, the world has been billions of years."
