On September 30, 2011, the Bristol "Global Community" High Energy Physics Symposium was officially opened.

“... Yes, there are many people who think that these advanced theoretical research in the field of high-energy physics have nothing to do with our daily lives, and it is not worth spending billions or even tens of billions of dollars on particle accelerators, but I am sure that none of you here think so......"

In the large conference room on the top floor of the Lingxiao Group, Noah Ellington, the first initiator of the conference, was giving this opening speech.

As usual at any academic conference, Ding Sheng chose to sit in the most inconspicuous corner, busy with his own business, "Guan Ju, do you have eyebrows?"

"The architectural model of this building has been scanned, Ding Sheng, you look here. ”

Guan Ju said, projecting a model map into Ding Sheng's mind, and enlarging a special mark in the interior of the building.

"Is this an elevator?" Ding Sheng was not sure,

In the area of architectural design, he is completely a novice, and he can guess a name just by looking at the model drawing.

"To be precise, it is an invisible elevator with an inner mezzanine that goes straight to a depth of 150 meters underground. ”

After listening to Guan Ju's answer, the answer is obvious.

Aside from the existence of a super particle accelerator, Ding Sheng really couldn't think of anything else worthy of Ellington building such a private underground elevator in his own group building.

At this time, Ellington on the stage had already introduced the topic of the meeting to the construction of a "super particle accelerator", and the physicists present except Ding Sheng listened very attentively.

When it was time to ask questions, physicists from all over the world could always ask some sharp questions, and in general, the academic atmosphere in the conference room was very strong.

However, Ding Sheng didn't care about any of this, as long as this meeting could keep Ellington out of his body, "Have you found a way to get into the elevator?"

"According to the use records of the elevator's internal system, this elevator is equipped with a double start-stop technology of 'DNA biometrics' + 'behavioral biometrics' with a very high security factor, and only two people can start it. ”

Needless to say, these two men must be Noah Ellington and his butler Abu.

DNA biometrics is basically the ultimate technology in the field of biometrics, coupled with the individual differentiation formed by long-term accumulated behavioral parameters, the difficulty of cracking can be imagined.

I believe that whether it is 007 or Mission Impossible, it will be quite a headache to encounter such a problem.

"How long does it take to force a crack?"

There is a saying that one force will drop ten, so when encountering such a complex situation, the best way is to use the advantages of the super intelligent system, and the technology can be crushed.

"That's the problem, give me some time to do crack these biometrics, but not enough time to get the elevator to cover the nearly 500-metre journey. I calculated that we would be intercepted at the latest when we were on the 21st floor underground. ”

Having built the elevator long enough to allow for a buffer time to ride the elevator, I have to say that these small details of Ellington are well perfected.

Ding Sheng didn't think about it, and immediately changed to another plan, "Such a large underground project, whether it is the entry and exit of staff or the transportation of materials, it must be other entrances, find out." ”

Guan Ju can model the entire earth, not to mention this small Bristol city, it only took less than two minutes to analyze several possible underground entrances according to various conditions.

Ellington is really cautious, and the nearest possible entrance is 25 kilometers away.

"Let's go..."

Ding Sheng said, got together just now, and immediately sat back.

Because at this time, Ellington on the stage seems to have finally begun to get down to business after going around countless circles.

“... Once this super particle accelerator is built, cosmic rays, exotrinos, angel particles, vacuum foam, magnetic monopoles, Higgs bosons, and even miniature black holes will all go further within the scope of study, if bolder ......"

Yes, Ding Sheng only heard this sentence "If you are bolder" before temporarily deciding to continue listening.

He wanted to see how bold Ellington was.

Or what is the purpose of his gathering of so many physicists here?

Everyone in the room fell silent, waiting for the young quantum mechanics scientist on the stage to continue.

"That's right, it's the Big Bang, and this super particle accelerator may eventually perfectly simulate the process of the Big Bang, which took shape over a billion years, until the universe stops expanding..."

"I knew it. ”

When he heard the words 'the universe stopped expanding', Ding Sheng almost instantly understood why Ellington had convened this academic conference.

Or rather, he finally understood how Ellington was close to planeswalking.

"I seem to get it. This time, Guan Ju's reaction speed was obviously slower than Ding Sheng's half a beat.

"Several variants of the Big Bang model believe that our universe will one day stop expanding and then begin to contract, in which case time will use this as a tipping point and begin to rewind until the universe collapses again into a singularity. A beautiful figure quietly walked in from the back of the conference room and sat next to Ding Sheng.

"Am I right?"

Catherine's arrival directly added a lot of scenery to the boring conference room.

"Of course, I don't think anyone would be stupid enough to question you. Ding Sheng smiled politely.

In fact, a simpler metaphor is that under this cosmic explosion model, what happens in the entire universe will happen all over again.

And your life, one day, will be like the movie "The Curious Case of Benjamin Button", rejuvenated.

It's just that an individual model like human beings is not worth mentioning at all to the vast universe.

If the individual human model continues to be reduced to a mirror, this phenomenon is called broken mirror reunion.

Shrinking to a basin of poured water, it is called covering water and collecting...

Let's continue to scale down the model to a single particle at the subatomic level in quantum mechanics, so that this particle can completely reverse the laws of physics that have always been in place, turning the future into the past, and the past into the future, playing with time, traveling through time.

In this case, there is still a "pointer" to distinguish the inherent past from the future, and that is the "arrow of time".

So Ding Sheng finally understood that everything Ellington was doing now was to simulate this model, and then seize this arrow of time.

"Is this theory feasible?" Guan Ju asked.

"It's hard to say..."

This is the first time since Ding Sheng's return that he has shown a lack of confidence on major academic issues.

In the Marvel world, you only need to find a way to enter the quantum realm, and because the flow rate of the quantum realm and the real world is different, you can travel through time and space by finding a suitable point in time.

And all kinds of different natures of time and space travel are also difficult coefficients.

The simplest thing is that Ding Sheng goes home, and only one space-time machine is enough.

For more complicated things, for example, if you want to go to a space-time where "you" exists, then the time paradox is involved, and you may need to use it with Pym particles to achieve better results.

It's even more complicated if you want to borrow something from that world and come back to use something like Infinity Stones, i.e., resist the time paradox.

Anyway, when Ding Sheng left Marvel, Tony Stark hadn't solved the problem.

But on Earth, at least so far, the tech tree has not developed to the level of the "quantum realm" at all, and people don't know that they can travel through time and space by entering the quantum realm.

So the "arrow of time" model that Ellington wants to use is a "non-Marvel-style" approach.

This method has not succeeded on Marvel's side anyway, or because Marvel has discovered the quantum realm, no one will take this path.

And most of Ding Sheng's scientific and technological knowledge comes from Marvel, and before he cooperated with Iron Man, he didn't even have a way to travel through time.

So on the whole, Ding Sheng does understand this concept a little better than most of the physicists here, but it is not at the level where it can solve this problem.

Why mostly?

Because there is one person here who is still quite buggy.

Thinking of this, Ding Sheng glanced sideways at Catherine beside him, if someone was destined to solve this problem, then Ding Sheng would definitely vote for her.

"You're right, I just searched for the 'Arrow of Time' in all the databases around the world, and then I got this information. ”

After Guan Ju finished speaking, he projected a copy of the information on the cover of the Silver Arrow into Ding Sheng's mind.

After scanning the first page, he saw the byline of "Katherine Oxton".

"This information was just updated a few days ago, and it has great reference value. Guan Ju added.

Thirty minutes later.

After a quick glance at the project document called "Arrow of Time", Ding Sheng couldn't believe his eyes, "It's too fast, as long as Catherine can solve the problem of 'Maxwell's Demon' that needs to detect and control the movement of single molecules, combined with the 'entropy' related state function, the high-entropy heat death state can guide the direction of the arrow of time... In this way, this model that can travel through time is established. ”

It's only one step away.

Except for shouting cowhide, Ding Sheng didn't know what to say.

Fortunately, Maxwell's demon is only an imaginary idea, and there is no possibility of realizing it yet.

Call...

Secretly relieved, before he could put his hanging heart back, Ellington's voice came from the podium again.

"With the help of this conference, I proposed a scientific blueprint for the 'arrow of time', hoping that everyone can participate and advance and retreat together..."

"At the same time, I can responsibly tell you that the super particle accelerator must be able to detect the movement of single molecules. In other words, humanity is very close to catching Maxwell, a scientific beast, so close that you can't imagine it!"

The words fell, and the applause was thunderous.

At the same time, a man and a woman in a corner of the conference room all changed their complexions.
