In the large conference room of Gliese 581g, the No. 1 satellite, it was simply crowded and lively, and more and more scientific researchers and reporters rushed to hear the news.

After the touch, there was a fierce and exciting discussion, especially about the reply work in this regard.

A female parliamentarian blushed and exclaimed, "We can build a large signaling device...... Let the people of the Golden Sun know that their efforts are not in vain, and let them know that our branch of humanity is still full of vitality and vitality. ”

"I believe that as long as the news is reported, the public is very willing to choose this way...... Not very willingly, but strongly demanding! People can be more emotional, more irrational than we are......"

"Our scientific and technological development in recent years has actually been quite good, although it has only been a hundred years, but it is really good."

"Everyone, everyone, please listen to me first." Listening to all kinds of confusion, Zhang Yuan raised his hand and signaled everyone to be quiet.

After so many years as the captain, there is still majesty. Soon, the room fell silent again.

Zhang Yuan said cautiously: "The reply letter must be replied to, there is no doubt about this." But first we need to figure out what kind of information to send, and we've made pretty good progress in technology over the years, so we have to pick some key points, if we send them all at once, how much data will be there? We simply can't afford this kind of attrition. ”

"The second is about the construction of electromagnetic wave communication devices, which 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 transfer the manpower to build Kunlun Mountain and build these large-scale communication devices......"

"Therefore, I intend to build a communication device to send this information to the Golden Sun after the construction of Kunlun Mountain is completed, and before the real start of the wandering project. It would be a good idea to let them know about our ambitious wandering plans, and to share the technology we have received from the aliens......"

"What do you think?"

The communication of electromagnetic waves between the universe is too energy-intensive. The attenuation of electromagnetic waves, the relationship between its intensity and distance obeys the inverse square law, that is, the distance is doubled, and the intensity is one-fourth of the original.

If you effectively send a light-year message and it consumes 1 amount of energy, then send a message 20 light-years away, and you need 400! Send a message 30 light-years away and you'll get 900!

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

According to the distance of Gliese 581 from Captan, this device needs at least ten kilometers in diameter. It is not impossible to consume 2 months of the productivity of a civilization.

Therefore, Zhang Yuan's words are quite reasonable, although it is important to send information, but first of all, you can't delay what you are doing.

"Secondly, the light-speed communication of electromagnetic waves, in the face of huge spatial distances, is not enough to see, and it will take more than 20 years to transmit the past, and it will not be a problem to delay for a few more years...... The Golden Sun should be able to estimate that we have only been here for a hundred years, and at the usual rate of development, a hundred years is not enough......"

"So, they don't wait blindly for us to hear back. Don't be anxious. ”

Many fanatics also quietly calmed down, considered from the perspective of civilization as a whole, and agreed with Zhang Yuan's point of view. After all, this is no ordinary email, click here, and you will receive it immediately.

Now comes the more important event, about the Golden Sun, the scientific and technological progress of the past 500 years!

All the text reports are very concise, with a large amount of data and even blanks, 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 stir up feverishly.

People have a kind of comparative mind, and they are using these materials to estimate each other's scientific and technological strength. Everyone eats the old books of the earth's civilization, and many things are half a pound and a tael, but the papers that are really sent are still quite innovative, including materials science, physics, mathematics, biology, and so on.

One of the most important papers was a study of supergravity and cosmic strings. A new way of propulsion for spaceships is contained in this paper!

"Use the cosmic strings to cause gravitational fluctuations and propulsion!"

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

So, scientists have introduced a concept called "cosmic strings".

The cosmic string, a hypothetical theoretically possible space-time. This is a special kind of "matter", as a one-dimensional topological defect, it can be said to be an extremely dense energy line, it is very thin, the theoretical diameter is only 10^-29 cm, which is equivalent to 10 times the radius of the hydrogen nucleus, and has a huge gravitational force.

What does that mean?

If the water freezes quickly, there will always be some cracks or bubbles in the ice, which will not be perfect. The cosmic chord is a topological defect that was born naturally in space after the Big Bang, similar to a crack in an ice cube.

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

Things involving gravity have become very complicated, especially since this kind of matter only exists in the microscopic environment, but the force caused by it is macroscopic, you must know that quantum mechanics and relativity have not yet been completely unified!

A doctor of physics sitting in the back was already yelling feverishly: "The best theory at the moment is called the theory of supergravity!" ”

"So, what is the theory of supergravity?"

Hearing someone talking, a group of reporters pounced on them as if they had seen a vicious dog with flesh and bones. Today's revelations are so big that they can already anticipate the sensation of the people!

For journalists, how can they miss the big news that caused a sensation?

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

“…… In the theory of supergravity, it is assumed that space-time has a Fermi-nature, and after introducing the anti-easy number, we use the real number and the anti-easy number together to describe this kind of space-time with Fermiability! ”

"Doctor, can you make that clear?"

In this way, general relativity treats gravitational interactions as the bending of matter to space-time, while elementary particle theory treats interactions as the effects of matter on quantum fields. If, in a certain force, the description of elementary particle quanta becomes part of the description of space-time geometry......"

"Through a method, the cosmic strings can be reinvigorated...... Oh, and it can't be said to be vitality, even if it is born of a small oscillation, it can show its own huge gravitational pull, which can suck the ship through! You know, the cosmic string itself has a lot of energy......"

Li Zhendong hurriedly patted him: "You see that so many beautiful reporters behind you are confused by you." You just have to say what the new way of moving forward is, and don't make it so complicated. ”

"Yes, Doctor, get to the point, get to the point."

The young doctor, seeing so many people watching his frenzied speech, blushed and squeaked speechless.

In particular, there were some cute female reporters who were staring at him curiously......

What the hell, he was just discussing with his peers, and he didn't speak to reporters at all.

Then another pile of microphones came over.
