Start a Subspace

Half an hour later, in the central meeting room of the Dongfang Panshi, a large number of scientists, research teams, and military brains attended this meeting.

Zhang Ran has always expressed the subject straight to the point, without any pleasantries: As you all know, we have encountered a three-dimensional fragment of a second-type universe. universe.

This is also the first universe that we have encountered that can barely be explored in the past six months.

Actually, it's quite tasteless. We humans have no way to enter it ourselves. We can only let robots enter for a period of time, but these robots are easily damaged. Just like our silicon-based universe, a series of broken cracks can't be retrieved. .”

But I still have a big question here. Why is there a black hole in the middle of the three-dimensional fragments? As the most extreme celestial body, shouldn't a black hole be the easiest to tear space and fall into the high-dimensional universe? Why does it remain in the three-dimensional fragments? Right in the middle? Are all our previous theories wrong?

After saying this sentence, he looked at all the experts in the audience with serious eyes.

After half a minute of silence, Dr. Xia Yu from Gaowei Lab pressed the button to speak.

Dr. Xia, please tell me.

He said: Theoretically, it is really not easy to preserve a massive celestial body like a black hole...

But I have two conjectures here. The first is that black holes can also exist in high-dimensional universes. After all, they are very different from normal celestial bodies. There is no concept of matter in black holes, and there are no quarks. There is no matter, no matter what kind of black hole, its ultimate properties are only determined by a few physical quantities (mass, angular momentum, charge), which is the famous black hole hairless law.

Since there is no matter, it is also possible for black holes to exist in high-dimensional space-time. Including mathematics, some properties of black holes in high-dimensional universes can also be speculated.

The second conjecture is that there happens to be a cosmic string passing through the black hole, causing this region to be in a delicate balance.

As everyone knows, cosmic strings support the universe and can stabilize space.

What will happen if the cosmic string meets a black hole? There may be some unknown phenomena on both sides, so the Hawking radiation that causes this black hole is extremely strong, which is probably millions or even hundreds of millions of times that of a normal black hole...

Speaking of this, Xia Yu became excited instead, and his character was exactly the same as his teacher.

Next, another scientist pressed the speaking button and said: I even doubt that it is a white hole. Because its radiation is a bit abnormal.

white hole?

Zhang Ran showed a strange expression.

In our universe, it seems that white holes have never been observed?

Yes, white holes are just a guess.

The white hole is also a strong gravitational source in conjecture, and its external gravitational properties are the same as those of the black hole, but the white hole can accrete the material around it to the boundary to form a material layer, which is continuously ejected outward.

Because everything is sprayed out, the white hole looks like a black hole...

Of course, it could just be a simple black hole.

These experts discussed various topics and various formulas like tongue twisters, making people confused.

Zhang Ran is no longer obsessed with these things, regardless of black holes or white holes, the most important thing for human beings is matter!

There is no substance here, shit is not here, the key is to leave immediately and find the next place!

He opened his mind and said: So with the level of human technology, can't even distinguish between black holes and white holes... Can these Hawking radiation be used?

Dr. Xia Yu immediately shook his head: You are referring to science-fiction-level technology like Hawking Ring, right?

Leaving aside the difficulty of manufacturing the Hawking ring, which is comparable to or even higher than the Dyson sphere, even if the Hawking radiation is increased by a factor of 100 million, it does not make much sense. After all, we already have controllable nuclear fusion, and energy is not enough. There is no shortage, there is no need to spend a lot of effort to enter a Lanhua world and collect Hawking radiation with low power.

But it's hard to comment on whether there are meteorites in it... Maybe there are meteorites revolving around the black hole at high speed.

The volume of this three-dimensional world is not small.

Zhang Ran cleared his throat: I will leave the problem of finding resources to you, our resource shortage is already very serious!

Our factory produces hundreds of thousands of robots a day, and these robots are being added to all aspects of production. Now it is equivalent to me raising all human beings. If I don't use my creation ability, half of the factory will shut down!

This deformed structure cannot be sustained for long ... I hope everyone knows this.

Zhang Ran's subtext is, no more money, no more money!

Many scientists present showed shame expressions.

In fact, people have so many resources at hand, that is, the small silicon-based universe, which reserves 500 billion tons of nano-cluster corpses, which contain all kinds of elements.

Unfortunately, the nano-cluster corpses are like a cloud of mist, which is troublesome and expensive to collect, and the machines working in this small silicon-based universe are easily broken.

This is also a manifestation of the lack of technological strength.

For example, silicon-based life can survive in the first, second, and third types of universes, but carbon-based life cannot, and even the created robots cannot. This is because the principles for the birth of intelligence are fundamentally different.

Everyone thinks, should we carefully explore this three-dimensional fragment? Or look for the next first type of universe that is easier to explore?

A scientist surnamed Zhu quickly said: Your Highness, silicon-based robots are our current research direction, that is, robots made of imitation silicon-based life, which can continue to work in different universes... The development of this kind of robot is relatively difficult. It could take years.

But I still feel that this third type of universe that we have found cannot be easily given up.

According to the current samples, the number of universes of the first type has been found to be one, which is the real universe we just came out; the number of universes of the second type is two, the universe where the Sibadi civilization is located and the one we are encountering now. The rest are all hydrogen-only universes of the fourth type, about 30 of them.

The current sample size is relatively small, and there is no way to estimate the specific proportion...but I can probably get some guesses.

A three-dimensional image appeared on the screen, and some starry sky models were played on it.

This is our universe, which I named the carbon universe, and there is another large group of universes, which I named 'silicon universe', which is the birthplace of silicon-based life. Why are there more silicon universes and fewer carbon universes? Maybe It is the rule of the silicon universe, and the deviation value is smaller than ours.

The professor cited a very classic mathematical model - normal distribution.

In the carbon universe where human beings were born, the deviations of various cosmological constants are relatively large, exceeding 3σ, and the probability of encountering them is below 0.1%. It's just because the original universe of human beings has just collapsed, so the probability of such cosmic debris has temporarily increased.

Relatively speaking, the deviation values ​​of the various cosmological constants of the silicon universe are small, so the number is more.

As for Lanhua, it is equivalent to the standard deviation of the regression of physical rules. The deviation of the carbon universe is the largest, and it will slowly return to the silicon universe with a slightly larger number. The silicon universe also has deviations, and then slowly returns to the largest number, which is completely impossible. The rules of the universe that carry matter. In the end, it turns into nothingness.

So that's how it is... Zhang Ran was serious about this three-dimensional image. In addition to the carbon universe and the silicon universe, there are other massive universes, which are empty, nothing at all.

These universes are the final result of Lanhua, and the whole process will take a very, very long time...

Of course, it is also possible that human theories are not enough to describe what these universes are, because the probe exploded as soon as it entered, and there is no way to get too much information.

Professor Huo said: Since we will understand what the 'silicon universe' is sooner or later, since we have encountered it now, we might as well try to find a way to see what's going on inside. In case there are silicon-based organisms or something... you can leave directly.

It is foreseeable that silicon-based life is not willing to fight in the high-dimensional universe. Therefore, the probability of the enemy's frantic pursuit is not high.

At this moment, someone pressed the speaking button, and it was Zhou Chengfeng, the chairman of the council: How much resources do we have to consume to explore this third type of universe? Cost-effectiveness is very important. If there are too many broken robots, we really can't bear it. kind of loss.

This three-dimensional fragment is not a small universe. If the machine in the small universe is broken, you can find a way to recycle it. If the exploration spacecraft here is broken, it will fall directly into the black hole. How can these resources be recycled? The exploration spacecraft should not be too cheap. ?”

This time, no one spoke.

The most important thing is money.

If the exploration spacecraft breaks down a lot of human families who are not rich, it will be even worse...

Moreover, the diameter of this space is 150 million kilometers, which is many times larger than the space of the Sibadi civilization. The probability of the spacecraft being damaged midway is really not small.

Those relevant scientists, researchers, engineers and their colleagues are talking with each other, and seem to be considering the countermeasures.

Your Excellency Erwin, can you clearly see what's going on inside? Someone thought of Mr. Erwin, a high-dimensional perceiver who has been cultivating his health and rest.

You can let him try... But when it comes to unknown celestial bodies like black holes, don't expect too much. Zhang Ran nodded.

You can also drop a hydrogen bomb to illuminate the world to see if there are meteorites spinning next to the black hole. If there are really meteorites, it is also cost-effective for us to break a few spacecraft and pull it back.

Of course, this plan also has flaws... If there are enemies inside, we will be discovered in an instant, and we will no longer be able to hide ourselves.

Only these two reliable and relatively cheap solutions were discussed.
