In the large conference room of Glitzer 581g, satellite No. 1, it was crowded with people and bustling. There were more and more scientific researchers and reporters coming after hearing the news.

After being moved, there was a fierce and exciting discussion, especially the call for replying to this area is very high.

A female MP said loudly with a red face: "We can build a large signal sending device... to let the people of the Golden Sun know that their strength is not in vain, and also to let them know that our branches of human beings are still full of vitality and vitality."

"I believe that as long as these news reports are reported, the people are very willing to make this choice... not very willing, but strongly demand! The people are more emotional and irrational than us..."

"We have actually developed technology over the years. Although it has only been a hundred years, it is indeed very 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 of captains, they still have majesty. Soon, the conference room became quiet again.

Zhang Yuan said cautiously: "The reply must be answered, and there is no doubt about this. But first of all, we need to figure out what information we send. Our technological progress over the years is quite good, so we must choose some key points. If we keep sending them all, how much data will be? We can't bear this consumption at all."

"The second 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 draw out the people who built Kunlun Mountain to build these large-scale communication devices..."

"So, I plan to build a communication device and send this information to the Golden Sun after the construction of Kunlun Mountain is completed and before the Wandering Plan is really started. Let them know about our ambitious Wandering Plan and share with them the technology obtained from aliens. This should be a better choice..."

"What do you think?"

The electromagnetic wave communication between the universe is too energy-consuming. The strength and distance relationship of electromagnetic waves follows the inverse square law, that is, the distance doubles and the intensity is one quarter of the original.

If the information that is effectively sent for one light year and consumes 1 energy, then sending the information to a place 20 light years away will cost 400! Sending the information to a place 30 light years away will cost 900!

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

According to the distance between Glitzer 581 and Captan, this equipment requires a diameter of at least ten kilometers. It is not impossible to consume 2 months of productivity of a civilization.

So, Zhang Yuan’s words are quite reasonable. Sending messages is important, but first of all, you cannot delay your own business.

"Secondly, the light-speed communication of electromagnetic waves is not enough in the face of huge spatial distances. It took more than twenty years to transmit it. It would be no problem to delay those few years... The Golden Sun should be able to estimate that we have only developed here for a hundred years. According to the conventional development speed, a hundred years are still not enough..."

"So, they won't wait for our reply blindly. Don't be anxious, either."

Many fanatics also calmed down and agreed with Zhang Yuan's point of view from the perspective of the entire civilization. After all, this is not an ordinary email. If you click here, you will receive it immediately.

Next is a more important highlight, about the Golden Sun, the technological progress over the past five hundred years!

All text reports are very streamlined, with a large amount of data or even vacancies, which makes people confused. But as long as you have a general meaning and research direction, it is enough to make people excited!

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

People have a comparative mindset. They are estimating the other party's scientific and technological strength through these materials. Everyone eats the old capital of Earth civilization, and many things are worth a lot, but the papers actually 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 propulsion of spacecraft is contained in this paper!

"Use cosmic strings to trigger gravitational fluctuations and advance!"

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

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

The cosmic string, a hypothetical space-time that may exist in theory. This is a special "matter". As a one-dimensional topological defect, it can be said to be an extremely 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, and has huge gravity.

What does it mean?

Take water freezing as an analogy. If water freezes quickly, there will always be some cracks or bubbles in the ice, which will appear less perfect. The cosmic string is a topological defect that naturally arises in space after the Big Bang, similar to the cracks in ice.

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

Things involving gravity become very complex, especially since this substance only exists in the microscopic environment, but the power it triggers is macroscopic. You must know that quantum mechanics and relativity have not been completely unified!

A PhD in physics sitting behind was already yelling frantically: "The best theory at present is called the supergravity theory!"

"So, what is the supergravity theory?"

When they heard someone talking, a group of reporters rushed up like a vicious dog with flesh and bones. Today's revelation was too big, and they could have predicted the sensation of the people!

For reporters, how could they miss the big news that caused a sensation?

But because I couldn't understand these papers, I was so anxious that I scratched my head and ears, and kept asking people for questions.

"...In the supergravity theory, it is assumed that there is a kind of ferminess in space and time. After introducing the number of opposition numbers, the real numbers and opposition numbers will be used to describe this kind of ferminess in space and time!"

"Doctor, can you explain it clearly?"

"It's like this. General relativity theory regards gravitational interaction as the bending of matter on space-time, while fundamental particle theory regards interaction as the effect of matter on quantum fields. If in a certain force, describing the quantum of fundamental particles becomes part of describing the geometry of space-time..."

"Through a method, the cosmic string is restored to vitality... Oh, it cannot be said to be vitality. It is to give birth to a small-scale shock. It can show its own huge gravity. This gravity can suck the spaceship! You must know that the cosmic string itself has a lot of energy..."

Li Zhendong quickly took a photo of him: "Look at how many beautiful reporters behind you are confused by you. Just tell me what the new way of promotion is, don't make it so complicated."

"Yes, Doctor, say the point, say the point."

The young doctor blushed when he saw so many people watching his fanatical speeches and couldn't speak.

Especially some cute female reporters were staring at him and looking at him curiously...

What are you doing? He just discussed with his colleagues and didn't talk to the reporter at all.
