Many people dream of traveling through time. After watching the conflicting film "The Tomorrow War," you'll know how absurd it is.

The so-called time travel is to travel from one time and space to another through certain technologies or special reasons. For example, we travel from 2022 to 3021 to see what the future looks like, or go to the Qin Shihuang era BC to see how he burned books and buried scholars. There are many plausible theories to support this phenomenon, such as time travel, etc. In science fiction, this phenomenon is even more common.

But the fact is that, so far, there has been no scientific evidence for a time travel event. Logically speaking, if such a theory and technology really exists, even if we cannot master it today, we will be able to master it in the future, so there will be many time travel events in the future.

But so far no such incident has occurred, so there are only two answers:

One is that the so-called time travel is impossible to achieve, otherwise we would have mastered this technology 10,000 years or 100 million years later. Why haven’t we seen people from the future coming back so far?

Another possibility is that humans have become extinct in the future, and they have become extinct before the invention of time travel technology. How long would it take to invent such a technology? With the advancement and development of modern human science and technology, if it is theoretically feasible, it should not take long. 100 years or 1,000 years? So will humans become extinct so soon?

Therefore, scientists tend to believe that time can only flow forward in one dimension, and that it is impossible to reverse time or travel through time and space. In this regard, Hawking, a famous physicist and popular science writer, conducted an experiment called the "Time Dinner" when he was alive, and got the answer that "time travel is impossible."

The process of the "Time Dinner" On June 28, 2009, Hawking carefully planned a gorgeous dinner party: he filled a restaurant at Gonville and Caius College, Cambridge University, England, with toasts and champagne, and balloons and ribbons tied to the pillars. The scene was grand and warm.

Hawking, wearing a suit and sitting in his specially made wheelchair, waited for the guests with his unique temperament. Above Hawking's head, there was a banner that read: Welcome Time Travelers.

The dinner started at 12:00 London time. The guests to be entertained at this dinner were special. They were not our daily friends and relatives, but time travelers from the future. Therefore, Hawking did not invite any modern friends, nor did he send any invitations. He just waited quietly for the future travelers to push the door and enter.

Why would anyone come without an invitation? This is the special design of the dinner. The formal invitations were sent out after the dinner, so that only people from the future can be invited, and people in the present cannot attend.

The biggest feature of this banquet is that it is highly confidential before and during the banquet. For modern people, we need to be invited in advance to attend a banquet, or at least be notified during the banquet, but future time travelers do not need to do this.

Because even if the invitation is sent after the dinner, even if it is sent a few days or even months later, as long as there are real time travelers, they can theoretically come to attend. Because they are at least decades later, or even hundreds or thousands of years later, they can only receive this invitation from historical materials. If time travel is really possible at that time, they can attend the appointment on time.

This is the biggest burden of Hawking's Time Dinner, and only future time travelers can solve this burden.

Unfortunately, Hawking struggled to hold on to his disabled body and waited patiently for several hours, but no one pushed open the door. He was a little disappointed and relieved. In an interview with the American technology blog Ars Technica, he pointed out: "The invitations to the time traveler party were sent out after the party ended. I waited for a long time, but no one showed up." Despite this, the experiment was successful, and the conclusion was that time travel is impossible.

Thus, the conclusion of Einstein's general theory of relativity has been confirmed once again: the speed of light cannot be exceeded and time cannot be reversed.

Many people questioned Hawking's dinner, saying that even if time travel is possible in the future, people may not necessarily come to the dinner, because Hawking's influence is not big enough, so why would they come to meet him? Besides, will people in the future definitely receive an invitation?

I disagree with this view. Even if Hawking's influence is not that great, the whole world knew about this dinner after it ended. The story of Hawking and his dinner party will surely go down in history. If there are time travelers in the future, how could they not know about it?

And if there really are future travelers, who would they rather meet than Hawking? So far, is there any evidence of a future person meeting a great man or scientist? And if those online rumors about John Titor and Andrew Carlson in the United States and Sergei Ponomarenko in Ukraine really happened, why do they always sneak around and avoid seeing the real scene?

Moreover, when our future descendants read this article, why can’t they come and look at our ancestors who are in doubt?

From this, let's see how time travel in science fiction can justify itself. "The Tomorrow War" is an American science fiction film released in 2021, telling the story of human time travel in 2022. One day in 2022, Dan Foster was watching the European Cup on TV with his 9-year-old daughter. Suddenly, the TV went dark and a group of people suddenly fell from the sky onto the court, shouting: We are from 30 years later, humans have been attacked by alien monsters and are on the verge of extinction, and we ask the current humans to go to support us.

Dan, who once served in the army, was selected and asked to travel through time and space to the future to provide support. The time is 7 days, and as long as he is alive, he will be teleported back. Dan said goodbye to his wife and young daughter. After entering the future, he saw a sea of ​​fire on the earth. All the cities were destroyed, just like a scene in hell. The monster called White Spike destroyed the human world. It feeds on humans. There are very few surviving humans.

On the future battlefield, Dan met his daughter, Colonel Murray Foster, who was already a famous biologist and a leader in the fight against alien monster invasion. Dan wanted to hug his daughter, but Murray coldly refused. She told Dan that he had changed his personality after returning from the future battlefield, abandoned his wife and daughter, and died in a car accident seven years later, so she hated him very much.

Dan and his daughter gradually reconciled during the battle. His daughter told him that these monsters existed in an alien spaceship that crashed into the Arctic glacier many years ago. As the earth's climate warmed and the glaciers melted, these monsters awakened and were released, starting to destroy humans from Russia. The monsters reproduced quickly and it was difficult for humans to kill them. In order to find a way to finally kill the monsters, Dan kept analyzing and studying the monsters' DNA.

In the end, the father and daughter and the resistance army desperately captured the female monster and developed a toxin to restrain the monster. However, countless monsters have broken through the last bastion of mankind, and mankind is about to become extinct. It is impossible to produce a large amount of toxins to kill the countless monsters that are overwhelming the world. At the last moment, Murray asked her father to ignore her and return to 2022 with the toxin sample to produce toxins to kill the monsters and save mankind.

The monster broke into Dan and his daughter's hiding place, grabbed his daughter and dragged her into the abyss. Dan watched his daughter being devoured by the monster in grief. At the moment when he was about to be killed by the monster, Dan's mission time was up and he was teleported back to the modern era of 2022. After returning, Dan, his surviving comrades and his father, who had once been estranged from him, created a toxin, sneaked into the Arctic glacier in Russia, blasted the ice, and found the crashed alien spacecraft.

After a desperate fight with the awakened monsters, Dan and his father finally killed the last female monster. Humanity finally won, Dan saved his daughter and humanity, and changed the future. Dan and his father returned home and happily embraced his wife and daughter, but his 9-year-old daughter had no idea about all this. Only Dan knew that his daughter would no longer have to suffer the terrible destruction disaster in the future.

The logical contradictions in "Tomorrow's War" are full of insults to intelligence. Logical contradictions 1. Since the future people knew that the monster that destroyed humanity first appeared in an alien spaceship that crashed in the Arctic glacier and was able to travel back, why didn't they send an elite force with high-tech weapons to the Arctic to eliminate the source of the monster? Why did they have to wait until it was almost extinct for modern people to rescue it?

Logical contradiction 2: Dan meets his daughter Colonel Murray on the battlefield in the future. His daughter says that he changed a lot after he went back and abandoned them, and thus became very cold to him. Dan was deeply shocked and blamed himself, and he would never repeat the same mistake again. So did he not meet his daughter and tell her this the last time he went back? But he actually only came here once, how can this be explained?

Logical contradiction 3: After Dan came back from the future, he destroyed the alien white spike monster that exterminated humanity in the future. Therefore, there would be no future call for help, Dan would not be sent to the future to fight, and he would not see his daughter in the future. All of this would not happen, and the future would be completely changed. So what reason does he have to travel to the future? How to solve this paradox?

According to the butterfly effect, any future person who returns to the present or the past will change the past, even if the change is very small. After the chaos amplification effect and chain reaction, the future will undergo major changes. In this way, future people may not have the need to come back, and modern people will have no reason to go there. This is a paradox, an irreconcilable paradox.

And in that battle, all the weapons used were conventional weapons, without even the surgical missiles and drones that are widely used now. Isn't this an insult to people's IQ?

Therefore, I think that time travel is an irreconcilable paradox that can only exist in the fantasy of self-entertainment and cannot be realized in reality. Please just have some fun after dinner and don’t take it seriously. What do you think? Welcome to discuss, thank you for reading.
