Is there an alien civilization in the universe in which the Earth lives?

I believe that no one can give an absolute answer to this question, and neither can Ding Sheng.

Dante knows that there is a multiverse in this universe, and in one of the parallel universes called the Marvel Universe, there are countless alien civilizations.

The earth in the Marvel Universe is because the cosmic coordinates are exposed, which leads to more and more aliens visiting the earth, and the earth has been plagued by disasters for a long time.

Because Heimdall has a pair of eyes that can see into the universe, Marvel Earth was included in the territory of the Nine Realms by King Odin of Asgard a long time ago, and the coordinates were exposed early.

Fortunately, Odin is a qualified guardian, and when the alien race Frost Giants attempted to use the Extreme Cold Ice Coffin to freeze all mankind in 963 AD, Odin led his subordinates to meet the battle, and did not let the flames of war burn to the mainland of Marvel Earth at the cost of one eye.

Under Odin's protection, the Nine Realms, including the earth, were relatively safe in the early stage.

Later, after a long time, Odin also got old, and Marvel Earth's technology became more and more prosperous, and the situation changed.

Until the eighties of the 20th century, S.H.I.E.L.D. scientists, led by Hank Pim, vigorously developed quantum research and achieved fruitful results.

In the 90s, Elias Starr, a scientist who was kicked out of the quantum team by Dr. Pym, caused a quantum anomaly of a considerable scale due to experimental errors, which caused a huge leak of energy in the quantum field and caused abnormal numerical fluctuations.

This data, through the quantum channel that had not yet been discovered at that time, broke out of the Nine Realms and spread to the entire universe, and was finally accepted by aliens.

Since then, Marvel's Earth has been separated from Odin's protection and officially entered the era of the Great Universe.

Later, the Kree and Skrulls came to Earth one after another, and the story of forging the strongest local superhero took place during this period.

In 2012, the Zetarians invaded Earth, and the Battle of New York took a heavy toll on the world. Fortunately, the Avengers were founded, and Marvel Earth finally has a team of superheroes with a certain ability to protect themselves.

So in the window period from the nineties to the establishment of the Avengers in 2012, was there no alien invasion?

Definitely.

During that time, the reason why Marvel's Earth was not tossed by aliens to the point of being torn apart was due to another person as strong as Odin.

Ancient One.

Marvel Earth is still like this, if the cosmic coordinates of its own Earth are exposed

Ding Sheng didn't dare to imagine what would happen.

If there is an alien civilization in the universe, and as it is said in "The Three-Body Problem", the universe is a dark forest, and every civilization is a hunter with a gun, if you don't destroy me, I will destroy you.

Then the earth, the crispy exposed coordinates, will definitely die.

Thankfully, the coordinates of the Earth have not been revealed at the moment.

First of all, the farthest Voyager series probe launched by mankind has just flown out of the heliosphere, and it has not even flown out of the solar system for decades.

Secondly, the electromagnetic waves used by human beings decay very quickly in the universe, and if the electromagnetic waves want to travel far, they must use a high-power emission source, which must be at the stellar level.

The probability of exposing the coordinates is also not very high.

And in the end, and at the same time, what Ding Sheng is most worried about is the quantum realm.

One of the most critical is quantum entanglement.

On the planet where Ding Sheng was born, the first person to describe "two temporarily coupled particles, which are still related to each other after they are no longer coupled" as "quantum entanglement", was Schrödinger.

Theoretically, the speed of information transmission in the state of quantum entanglement can exceed the speed of light, which violates the speed limit set by the theory of relativity, so at the time, the concept was quite unpopular with Einstein and was considered unscientific.

Everyone knows what happened later, even Einstein, it is inevitable that there will be times when he looks away, with the development of quantum mechanics, quantum entanglement is more and more accepted by physicists.

In 1964, John Bell proposed the famous "Bell inequality", which is mathematically formed by pxz-pzy≤1 pxy,

It provides a preliminary theoretical and experimental basis for the study of quantum entanglement.

In 1972, the first experiments to detect Bell's inequality were completed.

In 1996, Wei Jian, a 20-year-old master's student from China, went to Austria to study for a doctorate.

In 1998, Wei Jian participated in the experiment organized by the Austrian Academy of Sciences and successfully realized the exchange of entangled states.

In 2003, the Weijian team successfully realized the teleportation of free quantum states for the first time.

In 2006, a research team led by 19-year-old Katherine Oxton realized a decoy state scheme that extended the quantum state transmission distance to 100 kilometers.

In 2009, the Weijian team extended the distance to 200 kilometers.

Originally, according to the normal development of the science and technology tree, the next step in the research on quantum entanglement is to develop quantum satellites, and then in the next ten years, the transmission distance of quantum information can reach more than 1,000 kilometers.

At such a speed, it will take at least a few decades for earth scientists to touch the real quantum entanglement phenomenon, and then vigorously develop quantum technology to carry out ultra-long-distance quantum transmission, cross-solar system transmission, and galaxy transmission

Then, it is to discover the quantum realm in the quantum space and realize quantum traversal.

Such a set of processes can take as little as one or two hundred years, and as many as five or six hundred years.

During this period, the progress of other scientific fields was also changing with each passing day, and even if human beings really exposed the coordinates of the earth due to the development of quantum science, at least they had a certain ability to protect themselves at that time, so as not to sit idly by.

But things don't always go in the desired direction.

In 2010, CERN's quantum radar prototype detected the world's first non-experimental independent phenomenon of suspected quantum entanglement.

Fields that should have been explored by humans decades later have been put on the table.

And two of the smartest quantum physicists on Earth have embarked on a journey to study quantum entanglement.

The end result is nothing more than three.

1. Under the respective leadership of Wei Jian and Catherine Oxton, mankind has been smoothly researched in quantum entanglement, and finally succeeded in it.

Result: The exposure time of the Earth's coordinates was greatly advanced.

Second, the research did not go well, and an incident similar to "Elias Starr" broke out.

Result: The Earth's coordinates were immediately exposed.

3. The two discovered one day that this quantum entanglement was not an independent phenomenon, but a docking of time and space, a phenomenon caused by quantum traversal.

Ding Sheng's personal crossing exposed a small matter, and accidentally discovered the multiverse, and even connected to the Marvel universe

Here, there is no Odin, no Ancient One, no Avengers, and Ding Sheng, who has the strongest personal scientific and technological ability, has not even made the Ark reactor.

Don't say anything, gg.

In the final analysis, if Ding Sheng doesn't come back, there is no.

The sign of a man's maturity is that he knows how to take responsibility, so what Ding Sheng has to do now is to take on this responsibility.

There are two ways to do this.

prevent or disrupt human research on quantum entanglement;

Or comprehensively promote the earth's technology, and at the same time become higher, faster and stronger, and if something really happens in the future, defend the earth by force.

Fools can tell which one is easier.

So, Ding Sheng dialed Song Lizhang's phone, which was already the biggest person he knew.

"Dean Song, I have a question for you, can I have an interview?"
