Chapter 255
"Gemini stars..." Tang Zheng seemed to have thought of something, and hurriedly opened the illustration book.
Finger dots quickly in the light curtain.
Soon, the popular science content of the illustrated book caught his eye.
Gemini stars are an extremely rare celestial system in the universe.
It is composed of two high-temperature stars. The masses of the stars are almost equal, and the gravitational forces are also very close. They attract each other and rotate around each other.
Stars usually have their own celestial system, and the gravitational force generated by their huge mass will cause the surrounding planets to make circular motions around it.
"It means that the gravitational pull of Gemini stars is super doubled. There are more planets hidden around us than the solar celestial system. And..."
And, Gemini The gravity of a star is not always balanced.
The reason is simple, put a large magnet on the left and right sides of the small iron ball.
Then, the ball will definitely fly to the magnet closest to it.
The same is true of the principle of the Gemini star system.
Planetary celestial bodies will make a circular motion around the nearest massive celestial body.
Earth revolves around the sun and the moon revolves around Earth, based on this principle.
But the current situation is a bit special.
It's still a small iron ball and two big magnets.
When the ball flies to the east magnet, how about moving the west magnet to a position closer to the ball?
The small ball will naturally be attracted by the west magnet.
The positions of Star A and Star B of the Gemini stellar celestial body will alternate with each other, which causes the gravity to not always be balanced.
During this period, there will be a strongest point of tidal force and a weakest point of tidal force.
The so-called tidal force is a derivative of the branch of universal gravitation. The head of a rocket closest to the celestial body and the tail section farthest from the celestial body have different gravitational forces.
The gravitational difference will cause the rocket to be subjected to a pulling force that separates the head and the tail. This pulling force is the tidal force, which is also the cause of the ups and downs of the Earth.
"Master! I feel that I suddenly become very light!" With Lan Lan's call, Tang Zheng took away Tang Zheng's thoughtful gaze.
He jumped off the balcony on the second floor and felt the strength of his leg muscles.
Indeed, the whole person has become buoyant.
It seems that this is the time when the tide force is the greatest.
This is the celestial body that is one of the twin stars, when it is the closest to the alien sphere.
The huge tidal force will offset a part of the gravitational force of the alien ball, causing the entire body to become lighter.
Tang Zheng tried to make a leap.
"bang! !"
I jumped directly over the height of the three-story villa, Lan Lan's gaze also instantly lifted from the ground to mid-air, and then fell back to the ground. Live cry out in surprise.
"The master jumps so high!!"
In addition to the bonus from its own attribute, part of it is affected by tidal forces.
Tang Zheng tried again. When he jumped to the highest point, he broke a branch of the canopy.
After waiting for a few minutes, I jumped again.
It was also a leap with full strength, but this time it was obviously not as high as the last time.
Wait a few more minutes, then jump again, a little shorter.
After about two hours of experimentation, Tang Zheng roughly figured out the rotation speed of the twin star.
About 100 minutes of human time (estimated), the tidal force will reach a peak, the gravity of the earth's surface is relatively reduced, the tide rises, and people can jump higher.
"It means that 200 minutes or so is the time for the Gemini stars to complete one revolution."
Open the forum and check it out. Because of the version update, the forum at this time All kinds of posts appeared endlessly.
Tang Zheng used search to find the post he wanted.
A scientist of the original world, through a series of calculations, got a final value.
[The time for a complete revolution of the Gemini is ---Earth time 198:23:46, which is approximately equal to 200 minutes. ]
[And every half a revolution of Gemini, the tidal force on the alien sphere will reach its peak. ]
[By the way, because now you are in a different world from Earth, and the celestial system has also been changed, I would like to make a small suggestion here, suggesting to change the original time system , Because at present it will definitely not be 24 hours as a day, and all time systems will be overthrown. ]
[At present, it is known that the time for a complete revolution of the Gemini is 198:23:46. This time can be used as a measure. The time of one revolution of the Gemini is one Polluteus, or one wave for short, and the time of one half revolution is one Castor. Referred to as one card time. In the follow-up, I will further study the rotation speed of the alien ball and the speed of rotation around this huge blue star. Of course, my data is for reference only, you can each airs his own views. ]
In Tang Zheng's impression, Castor and Polydius are the twins in ancient Greek mythology and the origin of Gemini.
Facing the Gemini star celestial body in front of me, this naming is quite interesting in terms of artistic conception.
Tang Zheng silently liked his post.
Unexpectedly, a single stone stirred up waves.
[The low-key stealth people feel very embarrassed! ]
[Lost, low-key giants think it makes sense, and I think it’s just that way to name it! ]
[What should I do if other areas are not used like this? ]
[Let’s learn about gunfire diplomacy! Low-key giant, take us once again! ]
[What a nice name in a wave, let me ask, who doesn’t like the rough waves. ]
[Cars, fast cars! ]
Chapter 112 Entering the steam age and getting billions of points of civilization reward
The concept of a wave of time and a card time spread in just a few hours, and Has won the recognition of countless humans.
Subsequently, scientists in other regions have calculated that the period of the sphere of otherworldly revolving around the giant planet is very close to 300 wave hours.
The rotation period of the ball of different worlds is approximately equal to 20 cal hours.
