Wandering Spaceship in Deep Space Chapter 301: Cosmic Strings

In the large conference room of Gliese 581g, the No. 1 satellite, there is simply a crowd of people, and it is very lively. There are more and more scientific researchers and reporters who have heard the news.

After being moved, there was intense and exciting discussion, especially regarding the response work in this area.

A female congressman blushed and said loudly: "We can build a large signal transmission device... to let the people of the Golden Sun know that their strength is not in vain, but also to let them know that we are a branch of humanity. , Still full of vigor and vitality."

"I believe that as long as these news reports are published, the people are very willing to choose this way...not very willing, but strongly demanding! The people are more emotional and irrational than us..."

"Our technological development over the years is actually pretty good. Although it has only been a hundred years old, it is indeed very good."

"Everyone, everybody, please listen to me first." Listening to all the confusion, Zhang Yuan raised his hand to signal everyone to be quiet.

After so many years of being a captain, there is still some majesty. Soon, the meeting room became quiet again.

Zhang Yuan said cautiously: "The reply is definitely to be answered. There is no doubt about this. But first we need to figure out what information to send. Our science and technology has made good progress over the years, so we must pick some key points. , If you keep sending everything, how much data? We can’t bear this kind of consumption at all."

"Secondly, it is about the construction of electromagnetic wave communication devices. This is a big project. At present, the most important thing in the entire civilization is the Kunlun Mountain Project. It is impossible for us to mobilize the people who built Kunlun Mountain to build these large-scale communication devices... …"

"So, I plan to build a communication device to send this information to the Golden Sun after the construction of Kunlun Mountain is completed and before the wandering plan actually starts. We must let them know about our ambitious wandering plan, and They share the technology they got from aliens. This should be a better choice..."

"What do you think?"

The electromagnetic wave communication between the universe is too energy-consuming. The attenuation of electromagnetic waves, the relationship between its intensity and distance obeys the inverse square law, that is, when the distance is doubled, the intensity is a quarter of the original.

If you effectively send a light-year message, and the energy consumed is 1, then send the message to a place 20 light-years away, you will get 400! Send a message to a place 30 light-years away, and it will cost 900!

This also requires larger equipment and more energy. The original Deep Space Foundation was dragged down by this consumption, and the original Deep Space Foundation only sent signals 6 light years away.

According to the distance between Gliese 581 and Captain, this device needs a diameter of at least ten kilometers. It is not impossible to consume the productivity of a civilization for 2 months.

So, what Zhang Yuan said is quite reasonable. Sending a message is important, but first of all, it shouldn't delay what is at hand.

"Secondly, the light-speed communication of electromagnetic waves, in the face of huge distances, is not enough to see. It took more than 20 years to pass on the past 20 years. If it is delayed for a few years, it will not be a problem... The Golden Sun should It can be estimated that we have only developed here for one hundred years. According to the conventional development speed, one hundred years is not enough..."

"So, they won't blindly wait for our reply. Don't worry."

Many enthusiasts also calmed down quietly and agreed with Zhang Yuan from the perspective of the entire civilization. After all, this is not an ordinary email. Click here and you will receive it immediately.

Next is the more important highlight, with regard to the Golden Sun, the technological advancement over the past five hundred years!

All the text reports are very concise, and there are a lot of data or even vacancies, which makes people confused. But as long as there is a general meaning and research direction, it is enough to make people feel excited!

Soon, Zhang Yuan heard that the group of scientists behind him had begun to riot feverishly.

People have a comparative mindset, and they are using these data to assess each other's technological strength. What everyone eats is the foundation of the earth's civilization, and many things are half a catastrophe, but the papers that are really sent are still quite innovative, including materials science, physics, mathematics, biology, etc.

The most important paper is a study on supergravity and cosmic strings. A new way of propelling the spacecraft is contained in this paper!

"Using cosmic strings to cause gravitational fluctuations and advance!"

Under normal circumstances, after the Big Bang, all matter will be evenly distributed in the universe, but if matter is evenly distributed, it will be difficult to form real stars, galaxies, and clusters of galaxies, which is inconsistent with reality.

So, scientists introduced a concept called "cosmic string".

Universal strings, a hypothetical theoretically possible space-time. This is a special kind of "substance", as a one-dimensional topological defect, it can be said to be a very high-density energy line. It is very thin, with a theoretical diameter of only 10^-29 cm, which is equivalent to 10 times the radius of the hydrogen nucleus. Has a huge gravitational force.

What do you mean?

Take water freezing as an analogy. If the water freezes quickly, there will always be some cracks or bubbles in the ice, which is not perfect. The cosmic string is a topological defect naturally born in space after the Big Bang, similar to a crack in an ice block.

Because it does not electromagnetically interact with normal substances, it is difficult to detect it by conventional means. Therefore, there is only one macroscopic force related to the cosmic string-gravity.

Things related to gravity have become very complicated, especially this kind of matter only exists in the microscopic environment, but the induced forces are macroscopic. We must know that quantum mechanics and relativity have not been completely unified yet!

A PhD in physics sitting behind has begun to yell feverishly: "The best theory at the moment is called the supergravity theory!"

"So, what is supergravity theory?"

When someone was talking, a group of reporters rushed forward as if they had seen a dog with fleshy bones. Today's revelations are too big, they have been able to predict the sensation of the people!

For reporters, how can the big news that caused a sensation be missed?

But because I couldn't understand these papers, I scratched my head anxiously, and kept asking people to ask questions.

"...In the theory of supergravity, it is assumed that space-time has a Fermi nature. After the introduction of anti-variable numbers, real numbers and anti-variable numbers are used together to describe this fermi-like space-time!"

"Doctor, can you make it clearer?"

"This is the case. General relativity regards gravitational interaction as the bending of matter to space-time, while elementary particle theory ~IndoMTL.com~ regards interaction as the effect of matter on the quantum field. If in a certain force, Describing the quantum of elementary particles has become a part of describing the geometry of space-time..."

"Through a method to rejuvenate the cosmic string... Oh, it cannot be said that it is vitality. It is the birth of a small-scale shock, which can show its own huge gravitational force, which can bring the spacecraft Suck it! You know, the cosmic string itself has a lot of energy..."

Li Zhendong quickly took a picture of him: "You see so many beautiful reporters behind are confused by you. You just have to say what the new way of advancement is, don't make it so complicated."

"Yes, doctor, talk about the key points, talk about the key points."

The young doctor blushed at once seeing so many people watching his enthusiastic speech, and he was speechless.

Especially some lovely female reporters are staring at him and looking at him curiously...

What the hell, he just discussed with his colleagues and didn't speak to the reporter at all.

A bunch of microphones were handed over immediately.
