Although the conditions in ancient times were very difficult, I still want to go back to ancient times. Can cross?

In recent years, novels and TV plays have emerged one after another, and they are also very popular with everyone. Everyone also wants to travel to ancient times and live a moist ancient life by virtue of their Oracle ability. So is there really a crossing?

Let's take stock of several magical ways to travel through time and space.

1, black hole crossing

According to Einstein's theory, the passage of time is not static. Time passes slowly in some places and quickly in others. Hawking also wrote in the article that time is like a river, with different flow rates in different sections, which is the key to the journey to the future.

Hawking believes that the super-large black hole is a natural time machine, which will obviously reduce the time speed around the black hole, at least twice as slow as the earth's time. But the danger of approaching a black hole is very great, so it is difficult to experiment.

2. Wormhole crossing

In many sci-fi movies, time travelers use time machines to open a tunnel that can travel through time and space, but they can't be sure where to go. Physicist Hawking said that such an operation is difficult to achieve in reality, but the idea is not crazy.

For physicists, just visiting may be a wormhole. Hawking said that the wormhole is around us, but it is too small to be seen by the naked eye. Everything in the universe has holes or cracks, and this basic law also applies to time. Time also has tiny cracks and gaps. The gap smaller than that between molecules and atoms is called "quantum bubble", and wormholes exist in "quantum bubble".

3. Stimulate brain crossing

American scientists have discovered a new way to virtually teleport people back to the past. They will stimulate some parts of the human brain to achieve crossing.

A 22-year-old volunteer said that during the experiment, he was sitting in the laboratory, but he felt immersed in his pizza shop. From the shop, he could clearly see the scenery outside the window and even saw a local railway station when he was a child.

In the film Source Code, this concept has been fully expanded. The protagonist is a soldier, who basically declares his physical death. The scientist uses a technique to preserve his consciousness, and then weaves a script to let the protagonist transfer to the past memory to perform the task. Finally, the protagonist discovers that the world is actually a real world.

4. Faster than light.

Hawking believes that if the speed of the spacecraft exceeds the speed of light, then the spacecraft can avoid being inhaled by the black hole, so that the time in the cabin will not slow down. In this way, the spacecraft flew in the black hole circle for a week, and it may have passed 100 years on earth, so it can go to the future.

5. Bermuda Strait

People often disappear in Bermuda. 198 1 In August, the cruise ship "Sea Breeze" suddenly disappeared in Bermuda, and six people were missing. Eight years later, this ship miraculously appeared in Bermuda's primitive waters! The six people on board just felt that they lost their feelings at that time and thought it was just a moment. They were told repeatedly that it was eight years before they reluctantly believed it. If you want to cross, you can try Bermuda, but it is very risky and you can't come back more often.

6. Time machine crossing

1955, mallet, a physics professor at the University of Connecticut, wanted to find and build a time machine. He believes that using laser beam halo to create gravitational field, the gravitational intensity generated by halo is enough to distort space. When people walk into this laser beam halo, they will walk into the cycle of time, so as to achieve the effect of crossing.

20 10 in may, hawking published an article in the daily mail, pointing out three ways to travel through time and space. One is to enter a wormhole (scientists believe that wormholes are cracks and gaps in time), the other is to enter a black hole, and the third is to fly at a speed close to the speed of light.

Jules verne, a French science fiction writer, wrote the famous science fiction novel The Time Machine, in which the future described is the complete class polarization of mankind, even becoming a completely different species. Jules verne described the function and shape of the submarine in detail in his novel Two Wan Li under the Sea.

7. Frozen crossing

If you are frozen and resurrected decades later, then for you, you have crossed.

In 2005, American scientists exposed mice (non-hibernating animals) to a small dose of hydrogen sulfide and found that their metabolism slowed down because hydrogen sulfide would combine with oxygen in cell receptors. The experimental results showed that the body temperature of mice decreased to 65438 03℃, and the metabolic rate decreased by 65438 00 times. After 6 hours, the mice can be revived without any side effects.

1967, a doctor was allowed to freeze his lung cancer patients, and promised to be revived 50 years later, that is, to thaw in 20 17, but there was no follow-up news in 20 17, which may be a fundamental failure. Between freezing technology and biomedicine at that time, I think patients were basically declared dead when they were frozen, let alone resurrected 50 years later.

20 15 Du Hong, a science fiction writer suffering from pancreatic cancer in China, signed a freezing agreement in Alcor, USA, and his head and body were frozen separately.

8. Dragon Triangle

The terror zone with the same name as Bermuda Devil's Triangle in the Caribbean is located in the Dragon Triangle between China and southern Japan. If you think Bermuda is too far away, you can try here.

The terror of the Dragon Triangle has existed since ancient times. Jian Zhen's monks went to Japan for four times, all of which were narrow escapes. The Yuan Dynasty went to Japan twice because of the weather, which caused heavy losses.

1September 8, 980, Debyxia, a huge ship twice the size of Titanic, was loaded with150,000 tons of iron ore and came to a place 200 nautical miles from the coast of Okinawa, Japan.

This huge ship is perfectly designed and has been sailing at sea for four years, which is the most ideal period of mechanical condition. Therefore, anyone on board will feel very safe.

At this time, Debbie Charles' ship was attacked by a hurricane. But the captain is not worried about this. In his eyes, a well-designed large cargo ship like the Deby Charles should have no problem in dealing with this weather. He told people on the radio that they would arrive at the port later, a few days at most.

However, after the people on the shore received the captain's last message (we are struggling with the strong wind with speed of 100 km and the huge waves with a height of 9 meters), the Debyshire and its crew disappeared without a trace.

Hawking, a world-famous scientist, held a mysterious banquet before his death, but in the end no one attended, only Hawking sat in the hall and waited. It turns out that this is a time traveler's party. No invitation was sent to this banquet.

Because Hawking believes that if there is time travel technology in the future, it will naturally know that there have been such banquets in the past, so there will naturally be uninvited time travelers. But it turned out that the time traveler didn't arrive. This is very frustrating. Maybe time travel technology doesn't exist at all, maybe it's because of the so-called law of time and space. In short, we are still not sure about the authenticity of time travel.

Related research has made continuous progress. In 20 13, scientists demonstrated for the first time what it would be like to travel back to the past through computer models.

Because they found the space-time solution of the closed time-like curve in general relativity, people can use this special space-time to travel in time. Using this theory, they simulated the process of time travel.

If one day the "time machine" is born, many people will be delighted. The "time machine" may make people go back to the past to stop a war or a massacre, but it also means that it is very simple to change history.

But the paradox of time and space also exists. I went back in time and committed suicide. So who am I and who died in the past? In the end, we can only prevaricate with parallel universes.
