The so-called astronomical observations are actually the collection of electromagnetic waves in the universe. These electromagnetic waves are the sounds in the universe. They will tell the listener that the story of this universe has happened in the past. There are violent supernova explosions, quiet and larger structures. Nebula body, when and where such a black hole once formed there.

The reason why humans want to build various large-scale observatories and astronomical satellites is to collect electromagnetic waves. Although human eyes can also collect electromagnetic waves, there are limits. Human eyes cannot observe all kinds of electromagnetic waves in the entire universe as they wish. .

　　 And Huogu doesn't need to worry about this. It allows the cell to act as it wishes, which eliminates the need to specifically design a biological structure for astronomical observations.

　　Under the visible light, the planets in the planetary system are not very conspicuous, especially the cosmic background. It is not easy to identify them carefully.

However, if you add infrared and ultraviolet viewing angles, it will become very easy. The ultraviolet rays of stars will be reflected back after contacting the planets, and the star’s light itself has heat, which will heat the surface of the stars. In the infrared perspective, it will It produces microwaves that are very different from the cosmic background.

　　 Hogu soon discovered the asteroid belt, which was nothing but planetary rings, similar to the structure of Saturn’s rings.

　　 Suddenly, Huogu discovered that the planet he was observing was moving slowly. In terms of observation scale, this speed was undoubtedly quite fast.

　　 This is a big event, it can affect the planetary level, and how to say its mass, it can also get the star level.

　　 "If it's a wandering black hole, it's troublesome..."

"where?"

　　 Just as Huogu was nervously searching for observation information, the whine vibration from the cone was transmitted to the sensor cell through the entity.

　　 Huo Gu instantly understood where the problem was, and when he breathed a sigh of relief, he became nervous.

　　 It's relieved because it's not a horrible thing like a black hole, but because it's nervous because the problem lies in its cone, which is not a small pile of sand.

If you want to create something at the level of celestial bodies, it is far from enough to rely on biomolecular science, because it is a physical territory, and the atomic bonds between atoms. At this scale, the strength of the material will be severely weakened, so it needs to be added. Mechanics considerations.

　　 Even if the strong metal is strong enough and does not break, it will be ‘soft’. For example, Huogu, who is searching for the asteroid belt, is facing the swing from the cone.

　　 Originally, this situation should have happened long ago. If Huogu arranged the cone for construction elsewhere, it would probably enter the middle layer at most, and it would tilt and collapse under the action of the planet's latitude and rotation.

　　 However, it is very coincidental that Hogu’s location is on the equator, the problem of latitude is avoided, and the cone only needs to withstand the air resistance caused by the rotation of the planet.

　　 The cone shows a certain curvature as a whole under the action of air resistance.

　　 This is the cone as a whole, the part still looks the same as straight, and the curvature is at the decimal point level. This is the same as the planet's surface looks flat, and it is not easy to notice.

　　 The speed of the giant structure's swing is not violent, but the amplitude is getting bigger and bigger. Huo Gu knows that if this continues, the collapse will happen sooner or later, and the phenomenon caused by the collapse may be described as the collapse of the earth.

　　 If it is said that this is the same as that of the ancient universe, Huogu, of course, does not matter, but now there are a group of intelligent and intelligent creatures living on the surface.

　　 Because of his own mistake, a group of innocent people died, Huogu’s Three Views could not be accepted.

　　 "No, there must be a way to save it."

　　 Huogu used instructions to make a large number of titanium alloy refuges from the rhizomes, and then forcibly ordered those gatherers living near the equator to enter the refuges, and strictly forbidden to leave, he was racking his brains to think about countermeasures.

　　 "By the way, I can make it thicker and wider. If the interior is hollow, the quality will not increase. The required cells do not need too many. In order to ensure the strength, the metal body is increased to a certain thickness... Yes, that's it."

　　 Cone...No, the shape can no longer be regarded as a cone, it is closer to the big round chimney of a nuclear power plant.

　　The hollow area inside the truncated cone is enlarged under Huogu's command, and the inclined surface presents an inward **** inside. This structure can ensure that the center of gravity of the entire structure moves down while increasing the force area and reducing the pressure on the ground.

　　 After hundreds of day and night changes, such a period of busyness, Huo Gu can be considered to be able to take a sigh of relief.

　　 "Finally stabilized, shocked me."

　　 "Speaking of which, I made another big thing..."

　　 When Huogu noticed it, he discovered that what it unknowingly unknowingly would have covered an area equivalent to one-twentieth the size of an octahedron if it included the hollow part.

　　 From the original intention, Huo Gu didn't want to toss such a big thing at first, so he chose the previous design...

　　 "At least...I can still afford this guy. Compared with the octahedron, it consumes less and has no ability to destroy the atmospheric structure. UU Reading www.uukanshu.com"

　　 found an excuse for his behavior, Huo Gu turned to focus on another matter, that is, the calculation of the distance between the planets.

　　To say that the distance between stars is measured, Huogu still has no good way. It is not an astronomy major after all. This is beyond its scope of knowledge. However, if it is the calculation of the planetary system, Huogu still knows a little bit of information.

　　The method is to use radio signals to achieve distance measurement between planets.

The principle of the method is not tall, and it is the same as using sound waves to measure the depth of the canyon. A radio signal is transmitted to the observing planet. The distance traveled by the radio wave during this period of transmission and reception is calculated, and then divided by two. You can get the distance between the planets at that time, and then after several observations and the position of the star at that time, you can basically outline the orbit of the observed planet.

　　 The principle of radio is not too complicated, it is basically divided into two structures, transmitter and receiver.

The principle of the 　　 receiver is that the voltmeter is connected to a wire for electrons to circulate to form a closed loop without power. This is a radio receiver.

The 　　 transmitter is a little more complicated.

　　 The change in the strength of the current in the conductor will generate radio waves, and the change in the electric field caused by the electric waves will generate current in the conductor. This is the basic principle.

　　 Whether it is changing the resistance or switching the power supply, the radio transmission can be realized, and the strength of the radio signal itself depends on the strength of the current generated by the transmitter.

　　 Recalling his knowledge accumulation in the past, Huogu began to measure the distance of the planets in order to prepare for the following actions.

　　 Space travel has never been an easy task, especially for technology that is still in the stage of working fluid advancement.
