Volume 3 Chapter 31: Encountering a New Civilization (21/25)
In human philosophy of the universe, black holes are a concept that was proposed to prove the Big Bang theory. Pen Fun Pavilion wWw. biquge。 One of the theories that has been controversial for decades is to "prove" the existence of the "singularity" before the Big Bang. The other is to eliminate God's place in the creation of the universe.
But the funny thing is that the vast majority of scientists who believe in the Big Bang theory end up believing in God. Because they are faced with a problem: how did the matter before the Big Bang come about.
According to the Big Bang theory, the universe expands to its limit, eventually collapses and contracts, eventually becomes a singularity, and then the Big Bang again forms a new universe. But was there any substance before the first big bang, and if so, how did it come from?
As a result, some people put forward the theory of "repeated contraction-expansion" and the cosmic membrane theory, but these two theories could not exclude the role of God in the birth of the universe.
How did the universe come into being? Even the Three-Eyed Man can't explain it.
However, the Three-Eyed do not intend to prove that there was no god in the birth of the universe, they believe that the universe is eternal, ever-changing, and infinite. Data collected from the Three-Eyed Man proves that a black hole is nothing more than a compact object formed by the collapse of the remains of a massive celestial body. But it's definitely not dense enough to become a singularity.
Zhuang Bifan recalled the three-eyed man's theory of astronomical research and said: "The three-eyed man believes that the black hole is the heavy matter inside the star after the explosion and the heavy matter is gathered inward, and the closer it is to the core, the greater the pressure. Under high temperature and pressure, the atoms are compressed. If the mass of these heavy matter reaches a certain amount, the electrons in the atoms of the matter at the core are tightly compressed on the protons, and the protons no longer have an electric charge, which is a neutron star. If the mass is larger, and the proton is also crushed, it becomes a quark or even a subquark. But matter always exists, there is a limit after all, and the center of the black hole still has a core with volume. The gravitational pull of this core attracts most of the electrons that have almost no mass. These photons are elementary particles and also matter. In addition, when the black hole absorbs enough material, it will eventually explode due to excessive internal pressure, forming a nebula, which becomes the birthplace of new stars. ”
"The black hole theory of the Three-Eyed Man is a little easier to understand. At least there is no need to verify the question of why all matter can still shrink into a singularity after the temperature of the universe rises when it shrinks. "Sima Yun also dabbled in some astronomy at the beginning. But the more advanced things are simple introductions, even a kind of "I say I'm right" face, and use things that only mathematicians can verify with numbers.
However, the construction of mathematical models always uses only the most powerful factors that can prove themselves, and at the same time discards some parameters that are unfavorable to their calculations. As a result, after a new theory of the universe is proposed, there will be people who will put forward reasonable evidence to refute it half a year later. What's more, these new theories are based on a basic theory. What if all this basic theory is wrong?
For example, the geocentric theory and heliocentric theory of the year. Without Copernicus, perhaps human beings could now use heliocentrism as a basic theory to calculate a reasonable model of the universe.
But it can't be said that that's wrong, human beings always prioritize understanding small things. Confining the universe to a single confines does help humanity form a unified cosmic philosophy.
Zhuang Bifan put away the bad thoughts in his mind, and said with a smile: "Why don't we get closer and take a look." "Although the gravitational pull of the black hole is strong, the repulsive energy field of the mothership can cancel out a considerable part of the gravitational field, and it is not a big deal to observe the black hole closely.
Sima Yun shook his head: "Let's find another place to see what's interesting." "It's not dangerous to get close to a black hole, but the mothership is too energy-intensive, and she's seen the more spectacular scenes of black holes devouring stars, so there's nothing to see about it.
He didn't see that she was really interested, and was about to find a suitable destination from the star map that had been accurately detected. But I heard a loudspeaker in the room from the smart brain: "High-speed flying target has been found." The target is suspected of being a high-speed sailing fleet. ”
Zhuang Bifan was stunned. He didn't expect his previous excuse to come true, and he would encounter other civilizations in a galaxy that had never detected civilization signals before.
He said to Sima Yun: "You should first see if there is any planet you want to go to." ”
Sima Yun knew that he had to think about how to deal with the target he found, so he said, "I'll look for it first." You go busy with yours. ”
He went to the main control room and found that it was methodically monitoring the newly discovered UFOs. The large screen shows a series of blurry black shadows, one of which is particularly large in the middle, while the others are smaller. Some of the data flashed on the screen, which was the analysis of the detection signals reflected back by the intelligent brain from these flying objects.
He didn't see the distance of the target, so he asked, "How far?"
The Hanwu Intelligent Brain displayed the real-time distance data with those flying objects on the big screen, saying, "The distance is about 161,935 light seconds." The maximum length of the target is more than 10 to 20 kilometers, and the number of detectable objects is 91. ”
More than 160,000 light seconds, this second is still the time standard of the new earth. By this standard, one light second is equivalent to about 340,000 kilometers. The distance between the two sides is at least more than 500 billion kilometers. That's a lot of money, but it's a distance that can be crossed in less than half an hour for the Hopping Technique.
"How did you find out about each other?" If it was discovered suddenly, then it can be determined that the UFO is a product of civilization.
However, the commander of the Hanwu told him: "The last time the detection wave returned, this group of UFOs was not found. ”
Zhuang Bifan looked at the screen and found that the UFO was very close to a star, frowned and said, "You mean, they flew behind the star before so we couldn't find them?" Although the light wave detection is accurate, like light, it cannot penetrate large objects, and if the target is very close to the large celestial body, it is indeed difficult to detect them.
And the Hanwu does not emit light waves all the time. Rather, it is launched once every half day. The period is to wait for the reflected signal to be analyzed.
He thought about it for a while, since he could find this UFO, if the other party was a product of civilization, he would definitely receive this signal. If the other side does not have the technology to break through the speed of light and cannot analyze the light waves, then they may still be ignorant of their own existence.
"Every three seconds, a sixteen-fold pulse light wave detection signal is emitted to carry out uninterrupted detection of the target. ”
The largest target is only 220 kilometers, and even if the opponent is a combat fleet, it will not pose a great threat to its side. But he also had to be on the alert. The Reaper taught him a lesson: if the opponent is a high-level spiritual civilization, the size of the fleet is not a factor that determines victory or defeat.
He added: "The fleet accelerated, after which it stabilized at 5,000 kilometers per second. Order the fleet to put on alert level 2. ”
The sixteen-fold pulse detection signal emitted by the Hanwu is reflected by the UFO and only takes three seconds to be re-received by the Hanwu. Although such a signal is very energy-intensive. But for combat readiness, it is very important.
After a while, the Hanwu showed some real-time data on the target: "The target is sailing in a straight line at a relative speed of 9,100 kilometers per second, and the target speed and flight trajectory have not changed. ”
This also means that the flying object must be man-made. Not just because they are fast, but because they fly in a straight line. If they are not artificially controlled, their distance from the star must be affected by the star's gravity, and the trajectory will have a certain curvature before the gravitational effect disappears.
Although it had been determined that the other party was a product of civilization, Zhuang Bifan still did not make adjustments immediately, and after waiting for a few minutes, the other party still did not react, which made him suspect that the other party was still a low-level civilization. It has not yet entered the intermediate civilization stage of mastering the theory of Nyonir, and it is simply impossible to collect light wave signals.
He muttered for a moment and said, "Send a reconnaissance boat to get closer." ”
Soon a reconnaissance boat was launched from the Hanwu, and when the reconnaissance boat sailed at a distance of about 10,000 kilometers from the Hanwu, the reconnaissance boat suddenly disappeared, and it was replaced near the target.
Soon the Hanwu reported again: "The detection boat has been successfully replaced to the predetermined coordinates. It is about 300 light-seconds away from the target. ”
With the detection capability of the reconnaissance boat, the distance of 300 light-seconds is enough for it to accurately detect the appearance of the opponent.
Soon after, the detection boat sent back the detection data through the space displacement device.
The Hanwu reconverts the data into an image and displays it on a large screen. Hundreds of space battleships appear on the big screen. The length of the middle one, according to the data, should be about 16.3 kilometers. It is an elongated, thickened saucer-type ship with a length-to-width ratio of no more than 2.
There are two types of small warships, which are only about a kilometer long, but this type of warship is rectangular and has a length-to-width ratio of about 4. The upper and lower slopes are level, and the slopes on both sides are inclined at an angle of about 120 degrees. There are noticeable thrusters in the rear.
Such space ships obviously belong to a low-level civilization. Such thrusters are very backward and need to carry a lot of material for propulsion. And the acceleration is very small. For the cosmic combat methods of advanced civilizations, such a battleship cannot even be called cannon fodder.
Don't look at how fast they fly. But in reality, as long as they calculate their flight trajectory and attack from tens of lightseconds away, even if they can detect the attack in advance, there is no way to avoid it. Because such thrusters, for the mass of these warships, simply cannot change the trajectory of the voyage in tens of seconds.
For an advanced civilization, attacking such a battleship, not to mention every shot, but absolutely every salvo will work. Moreover, in this way, the battleship can completely jump to within ten light seconds of the distance, and then Shi Shiran will attack. You don't need to shoot a salvo, you can hit them one by one with a direct shot. Because their detection means are still the speed of light, in the event of a laser cannon attack, there is no time for early warning.
Seeing this detection result, Zhuang Bifan was basically relieved. The detection boat actively detected the other party at close range and did not react, and there was a chance that eight out of ten [sensitive numbers that top his lungs] nine was not a super spiritual civilization.
For such a low-level civilization, he put his mind at ease, but he had the heart to get in touch with this civilization. But this time I came out to accompany Sima Yun to relax. He asked to hear what Sima Yun meant.
