Zhang Ran paused for a while and said, "The second most important task is the relevant experiment of cosmic strings. Cosmic strings are related to basic physics, dark matter and high-dimensional universes."

"Next, Professor Huo Dong from Gaowei Laboratory, will introduce this content."

Cosmic string detection is considered to be a very cutting-edge science.

In fact, even the Sibadi civilization does not know whether the "cosmic string" really exists.

Because cosmic strings are equivalent to dark matter, they are something hidden, only gravitational wave telescopes can discover them.

The gravitational wave telescope of the Sibadi civilization was developed during the battle with silicon-based organisms.

In just 10 years of war, the potential of the Sibadi civilization has been greatly developed. After all, they are a powerful civilization that has completed the fifth industrial revolution, and they do have some background.

But the Sibadi civilization could not study cosmic strings, because cosmic strings only exist in the real three-dimensional universe, and they had already fallen into the high-dimensional world at that time.

"And the cosmic string may be an important reason for the catastrophe of the universe."

Professor Huo Dong's argument quickly attracted the attention of everyone in the venue.

It is precisely because of the great tearing disaster that a series of subsequent events have been led to.

If there was no great tear in the universe, humans might still live a drunken and dreamy life on the earth. The final outcome of human beings may be similar to that of the Sibadi civilization, laying solar panels on the surface of the planet to form a global power grid, and then inventing 3D semiconductors to enter the meta-universe era.

Well, this is actually a pretty good ending.

Or it may be slower, it will take a hundred years, two hundred years, or even more, and it will never be able to achieve the current achievements of the Sibadi civilization.

After all, the earth's civilization is in a state of fragmentation, with national hatred and family hatred and religious conflicts that cannot be resolved in the foreseeable future.

And the Westbadi civilization at least has a coalition government...

Thinking of this, humans are actually inferior to the Sibadi civilization.

Zhang Ran shook his head and threw these random thoughts behind his head. Natural disasters have already happened, and it is meaningless to think so much.

Professor Huo Dong was still on the stage, enthusiastically explaining his latest discovery: "...The existence of cosmic strings will bend the surrounding time and space. Just as a black hole will bend the surrounding light to cover up its own existence."

"But black holes emit Hawking radiation, but the cosmic strings are very quiet and nothing can be emitted, so it is even more difficult to discover than black holes. Only high-precision gravitational wave telescopes can discover them."

"The mass of a string depends on the density and tension of the string. According to our conventional theory, the mass of a 2.5 cm cosmic string is about the same as that of Mount Everest, and the mass of a 1.6 km length of a cosmic string has the same mass as that of the earth."

Professor Huo Dong drew some arrow-like symbols on the blackboard.

According to the unified theory of "weak current", cosmologists believe that the cosmic string was almost the first product of the universe at the 10th-35th second after the Big Bang.

The closer you get to the Big Bang, the higher the temperature in the universe.

"Let's look at it against the time arrow: the universe reached a temperature that was enough to produce pairs of electrons from photons - positrons, at the 30th minute after the Big Bang."

At the third minute, the temperature was high enough to split the nucleus into protons and neutrons.

At the first second, the weak force begins to take effect.

At 0.01 seconds, the temperature was high enough to split the protons and neutrons into quarks, which then bind through strong interactions.

"What did the substance look like before this?"

"In the extremely high energy state in the initial stage of the Big Bang, there is no difference between gravity, electromagnetic force, weak force and strong force, and it only exists in a unified field. However, ultra-high temperature phase change will occur at that time. The cosmic string is the remains of this ultra-high temperature phase change. It is a linear defect in the phase change. These defects contain the high-energy residue after the Big Bang - the extremely thin and heavy unified field, that is, the cosmic string."

Professor Huo became more and more excited as he spoke. He was full of red light: "The existence of the cosmic string was inferred based on the theory of great unification. If it exists, it will exist as a high-dimensional matter for a long time and stable manner in the high-dimensional universe."

"As we all know, most of the matter familiar to us humans cannot exist stably in the high-dimensional universe. For example, our spacecraft will decompose in one picosecond if we enter the high-dimensional world. It is a decomposition at the atomic level, and there is no possibility of being spared."

"Multiple quark particles can last longer, between 1 nanosecond and a few seconds."

"High-dimensional silicon crystal, as the spoils obtained in the silicon-based universe, is the longest-lasting substance we have. Its half-life is 1.2 hours, which means that like radioactive elements, it decomposes half every 1.2 hours. This is also the main reason why there are three words "high-dimensional" in its name."

"But we don't understand how this high-dimensional silicon crystal is made for the time being, so we can only determine that it is a strange substance."

"If the cosmic string really exists, it has been stable for more than 13 billion years! Studying its characteristics will be of great help to our activities in the high-dimensional universe. If we can study matters with slow decomposition speed, it will be of great help to both materials science and the battle in the high-dimensional universe."

Huo Dong's last words expressed Zhang Ran's heart.

Nowadays, humans' combat effectiveness in the high-dimensional universe is almost zero.

Whether it is a hydrogen bomb, an electromagnetic gun, or the latest invention of high-energy laser, there is no way to leave the curvature bubble. Once it leaves the three-dimensional space, these things will be directly decomposed. What else can I do?

High-dimensional silicon crystal is the only weapon... and it triggers an explosion through ultra-high-speed projection.

But it’s a bit extravagant, and it can even be said to be too extravagant! High-dimensional silicon crystal is a limited spoil.

An enemy that can attack in the high-dimensional universe is likely to be defeated by projecting some high-dimensional silicon crystals.

so……

"Does it take out a cosmic string and suck others like a whip? Is the wars in the high-dimensional universe all close-range hand-to-hand combat?" Zhang Ran asked in his mind, "It's not right. This whip is too heavy. The 1.6-kilometer-long cosmic string is comparable to the mass of the earth. It is impossible for ordinary machines to take this whip."

Lin Qiuyue, who was sitting in the first row, asked: "Professor Huo, is the tearing of the universe caused by the strings of the universe?"

This is another very important question.

"It is indeed possible that cosmic strings have huge tension. It is precisely because of the existence of these strings that the universe will not be over-expanded." Huo Dong took an example of a balloon, "It is very simple to say that the larger the balloon expands, the greater the weight the 'string' will bear, and the more likely it is to tear it."

"Of course, the death of the universe will not be as fast as a balloon. Once the balloon cannot withstand tension, it will explode in just 0.1 second. Instead, our universe tear up one by one, and this tear spreads from all directions through super-light speed. The whole process may take hundreds of thousands of years, or even more than one million years."

"Professor Huo, has the universe reached the age of natural death?" Lin Qiuyue asked another question.

This question sounds strange, but it points directly to the facts.

Zhang Ran immediately thought of a creepy question. This question was really cold, making the hairs in his pores stand up.

"I don't know if our universe is natural death."

Professor Huo waved his hand and said helplessly, "Our scientific researchers have come up with many assumptions. If cosmic strings are really a very precious thing... Of course, it is just a hypothesis. The number of cosmic strings should be quite large. After all, they support the existence of our entire universe, and the number is definitely not rare! It can even be described as the three words "Baoshima".

"And the cosmic string is very heavy. I just explained that a few centimeters are comparable to a mountain. Even if we humans meet it, we cannot collect it and use it..."

"But if the cosmic string is really a high-level energy source, there will inevitably be a stronger civilization that can be used!"

"The universe is so vast and there are so many galaxies. Even our Milky Way is a very young galaxy. Those elliptical galaxies are generally much older than the Milky Way."

"Our universe has a high probability that there is no moral system that regulates all civilizations..."

"So, everyone should be able to understand what is happening now. Since I can't confirm whether other advanced civilizations are collecting cosmic strings, why don't I collect these important strategic resources?"

"Hiss--" The conference room suddenly fell into silence!

Zhang Ran sat in the seat, sighed slightly, and understood what Professor Huo meant.

Cosmic strings, perhaps very common.

It's as common as stars in galaxies.

But it is also very useful and more valuable than normal matter... After all, it is something that was born at the first time in the Big Bang.

The cosmic strings support the existence of the entire cosmic membrane, preventing the universe from tearing apart too early.

If that's true, the final result can be expected.

He smiled bitterly and took a sip of water. He felt a little frustrated no matter how he thought about it.

That is... some advanced civilizations, endlessly developing cosmic strings, led to the occurrence of this disaster.

This is what Professor Huo wants to express!

He could only sigh and pour a cup of water "gurgled" down. How can I say this feeling of frustration... It's like the uranium mine on the earth. A country with the ability to develop uranium mines must find ways to dig it, and then claim to the outside world that he is "peacefully utilizing nuclear energy."

The cosmic string is even more important than uranium ore, and it is likely to be a kind of scattered thing.

As long as a civilization develops a gravitational wave telescope with sufficient accuracy, it is not difficult to discover cosmic strings.

But it is this kind of cosmic string that supports the existence of the universe itself. If it is drawn too much, or even only one thousandth, one thousandth, or even one billionth, or one trillionth, the universe will aging prematurely and cause a catastrophe!

"In this case, what will humans do?"

Asked himself, Zhang Ran soon had the answer.

If humans become high-level civilizations, they will still dig.

Because humans do not have enough ability to restrain other high-level civilizations. The universe is too big and too big. The observable universe, and the unobservable universe, God knows which corner of the civilization is secretly digging the strings of the universe, hundreds of billions of light years, is it possible for humans to monitor it?

Then the same is true for other civilizations. With this idea, everyone should just dig together!

A truly high-level civilization has long been able to travel through the high-dimensional universe without dying. What does it matter if the universe dies? Just change it to another universe.

What perishes are just low-level civilizations... What does their life and death have to do with high-level civilizations?

This feeling of being trampled on by the roadside ants is really uncomfortable.

The carefully cared for flowers in the family finally walked out of their warm homes, and what came towards them was the iron fist from the dark society. Who said that the moral qualities of aliens must be more noble, just like the satirical paintings of the painter Erwin, aliens may also be eating each other in the same category?!
