On June 28, 2009, Hawking sat alone in the room, with delicious food and champagne on the table, and ribbons hanging on the wall, which could be seen that this was a banquet, but it was curious that the scene was empty except for Hawking and the film crew, such a banquet was really rare, until the sun set that day, no one came to the banquet.
Some people asked Hawking, why didn't everyone receive an invitation to come to the meeting? At this time Hawking said: My banquet invitation has not yet been released, and I plan to send out a message in a few days. In fact, the banquet was an experiment that Hawking had done, and the people he wanted to invite were the time travelers. As a result, everyone saw it, and no one came to the banquet.
Of course, we know that Hawking's experiment is not so rigorous, but it is actually quite interesting, which is also a great scientist's bad taste! What is time? From the initial Newton to Einstein to Hawking, who died two years ago, he had a different view of time. The fascinating place of time is precisely its unidirectionality and irreversibility, and the crossing of time is precisely a breakthrough to break the shackles, but it is very difficult to achieve.
The idiotic language of time travelers
In recent years, with the development of the network, everyone has also realized the importance of traffic, being concerned means that there are economic benefits, so there are many people at home and abroad who call themselves time travelers, as a gimmick to attract everyone's attention. One of the more famous in this circle is Noah, who claims to be from 2030 and passed the lie detector test on a show. It's just that things have become more and more skewed later, and the live broadcast room he is in needs to pay a fee to enter, and at the same time, it is also necessary to charge him questions.
At the beginning of 2022, there are several "time traveler" gods on the Internet, and we may as well look at what they all say with a lively mentality.
01, the first god gave three time nodes
On March 15, 2022, a supervolcano will erupt, the ash it produces will cover half the earth's atmosphere, everything will fall into darkness, no light means that plants cannot photosynthesize, then the entire food chain will collapse, and finally a large number of species will go extinct, going to a desperate situation, which is actually similar to the extinction of dinosaurs 65 million years ago.
At the same time, the volcano that can reach this scale may be the supervolcano of Yellowstone National Park in the United States, which has not erupted for 650,000 years, and according to the world interval, there is indeed a possibility of happening at any time.
On June 28, 2022, a plane suddenly disappeared from radar signals and was found a month later in the other half of the planet, but people on board said they were flying normally, and only about three hours had passed.
Einstein's time dilation may be used to explain this phenomenon, but only if the plane is fast enough to approach the speed of light, which is obviously impossible. Or the "Einstein-Rosen ring" predicted by Einstein's general theory of relativity, which is a wormhole.
On August 2, 2022, humans found other biological civilizations, but not in space beyond Earth, but inside Earth. In fact, the statements about the people in the center of the earth are all old yellow calendars from a century or two ago, and who thinks that people often move out now.
02, the second time traveler god also jumped out to speak, also gave three time points (I don't know if they are 0.0 who travel back from an era)
His point is also interesting, the time node is March 11, April 19 and September 17, he said that at these three points in time will first be found "man orangutan", which has the characteristics of both humans and chimpanzees, as the name suggests, is a combination. I think that the inspiration for his term should have come from "lion tiger beast" or "tiger lion beast". The second is the mention of a new coronavirus, which he calls "Omega", and we don't know what it has to do with watches. Finally, there is the giant beast found in the marine ecosystem, which is four times larger than the current largest animal, the blue whale.
I have to say that in order to become a "time traveler" imagination must be enriched, otherwise how to describe the future?
Is time travel really possible?
Many people like to watch science fiction novels or movies, and have seen many ways to travel through time, but in fact, from a scientific point of view, the only thing that supports time and space travel is "wormholes". "Wormholes" are not fanciful things, but are supported by a special solution in Einstein's general relativistic field equations, and scientific theories that "wormholes" structures are real, but so far no figure has been found.
As for the oft-mentioned travel through time and space beyond the speed of light, this statement is completely nonsense, and it is often believed by many people that objects with rest mass simply cannot achieve faster than the speed of light. Of course, there are really examples of faster-than-light speeds in the universe, such as the expansion rate of the universe, the speed of quantum entanglement, and quantum tunneling.
Einstein's general theory of relativity has a deeper interpretation of gravity, the essence of gravity is the result of the curvature of space-time, in an easy-to-understand sentence, that is, the mass of the object tells how to bend, the curved space-time tells the object how to move, in this time and space become a whole and can be bent.
Then there may be a special situation for curved space-time, two points in different time and space in the universe, because the existence of space-time curved space-time they are combined, then passing through this point also means crossing space-time, which is the essence of wormholes. But scientists don't think going through a wormhole is a comfortable thing to do, and you might first be torn into pieces and turned into elementary particles.
There is a saying that there is a white hole in the universe, which is completely opposite to the nature of the black hole, and everything swallowed up from the black hole will erupt from the white hole, then the combination of the black hole and the white hole becomes a "wormhole model", of course, these are only the existence of the prediction.
Say at the end
For the future we can not predict, no matter how far or near, 2022 is not ordinary no one knows, but we must face it bravely. Leaving aside everything, the extreme weather brought about by climate change may still occur in 2022, which is basically certain, whether it is heavy rain, heavy snow or extreme high and low temperatures.
If humanity does not solve the problem of climate change, it will never be able to avoid the emergence of extreme weather.
