Deep Space Fleet

Biquge www.xbiquge.bz, the fastest update of Wandering Fleet in Deep Space!

And in Gliese 581g, the large meeting room of the No. 1 satellite, it was crowded with people, and it was extremely lively. More and more scientific researchers and reporters came to hear the news.

After being moved, there was an intense and exciting discussion, especially the response to this aspect was very loud.

A female congressman said loudly with her face flushed: "We can build a large signal transmission device... Let the people of the Golden Sun know that their efforts were not in vain, and also let them know that our branch of humanity is still full of energy." Liveliness and vitality."

"I believe that as long as these news are reported, 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 not bad. Although it's only a hundred years old, it's really good."

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

After serving as the captain for so many years, the majesty is still there. Soon, the conference room became quiet again.

Zhang Yuan said cautiously: "The reply letter must be answered, there is no doubt about it. But first we need to figure out what kind of information to send. Our technological progress over the years has been quite good, so we must pick some key ones. If a Send all the energy, how much data is there? We simply can’t bear this kind of consumption.”

"The second is about the construction of electromagnetic wave communication devices. This is a big project. The most important thing in the entire civilization at present is the Kunlun Mountain project. It is impossible for us to allocate the manpower for the construction of Kunlun Mountain to build these large 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 really starts. 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?"

Electromagnetic wave communication between universes is really 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 1/4 of the original.

If the energy consumed to effectively send a light-year message is 1, then sending the message to a place 20 light-years away costs 400! Send a message 30 light-years away, that's 900!

This also requires larger 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 between Gliese 581 and Kapteyn, this device needs to have a diameter of at least ten kilometers. It is not impossible to consume the productivity of a civilization for 2 months.

So, Zhang Yuan's words are quite reasonable. Sending information is important, but first of all, you can't delay the matter at hand.

"Secondly, the speed of light communication of electromagnetic waves is not enough to see in the face of huge spatial distances. It will take more than 20 years to transmit it, and it will not be a problem if it is delayed for a few more years... The Golden Sun should be able to estimate , we have only developed here for a hundred years, and according to the normal development speed, a hundred years is not enough..."

"So, they will not blindly wait for our reply. Don't be impatient."

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

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

All text reports are very concise, with a lot of data and even blanks, making 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 commotion fanatically.

People have a comparative mentality, they are using these materials to estimate the technological strength of the other party. Everyone eats the basics of the earth's civilization, and many things are not the same, but the papers that are actually sent are quite innovative, including materials science, physics, mathematics, biology, and so on.

One of the most important papers is a study on supergravity and cosmic strings. A new propulsion method for spacecraft is contained in this paper!

"Use cosmic strings to trigger gravitational fluctuations for propulsion!"

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 galaxy clusters, which is inconsistent with reality.

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

Cosmic strings, a hypothetical theoretically possible space-time. This is a special "substance", as a one-dimensional topological defect, it can be said to be a very high-density energy line, it is very thin, and its theoretical diameter is only 10^-29 centimeters, which is equivalent to 10^- the radius of the hydrogen nucleus 17 times, has a huge gravitational force.

What does that mean?

Take water freezing as an analogy. If the water freezes quickly, there will always be some cracks or air bubbles in the ice cube, which will not be perfect. Cosmic strings are the topological defects naturally born in space after the Big Bang, similar to cracks in ice cubes.

Since it does not interact electromagnetically with normal matter, it is difficult to detect it by conventional means. So, there is only one force related to cosmic strings in the macroscopic view——gravity.

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

A Ph.D. in physics sitting in the back has already started yelling frantically: "The best theory at present is called the supergravity theory!"

"So, what is the theory of supergravity?"

Hearing someone talking eloquently, a group of reporters jumped on it as if they saw a vicious dog with fleshy bones. Today's news is really too big, they can already predict the public's sensation!

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

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

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

"Doctor, can you explain a little more clearly?"

"It's like this. The general theory of relativity regards the gravitational interaction as the bending of matter to space-time, while the theory of elementary particles regards the interaction as the effect of matter on the quantum field. If in a certain force, the description of the elementary particle quantum becomes Describes part of the geometry of space-time..."

"Through a method, let the cosmic strings regain their vitality... Oh, it can't be called vitality, it is the birth of small-scale shocks, and it can show its own huge gravitational force, which can attract the spaceship! You have to know that the cosmic string itself has a lot of energy..."

Li Zhendong quickly patted him: "You see so many beautiful journalists in the back are confused by you. You just need to tell me what the new promotion method is. Don't make it so complicated."

"That's right, doctor, get to the point, get to the point."

Seeing so many people watching his frenzied speech, the young doctor suddenly blushed and was speechless.

Especially there are some cute female reporters staring at him curiously...

What are you doing, he was just discussing with his peers, he didn't speak to the reporter at all.

Immediately afterwards, another bunch of microphones were handed over.
