Chapter 357 Wrong calculation, wrong answer

Thanks to Liu Peiqiang's handling of Moss, Liu Qi can now spare a 550W quantum supercomputer to calculate the possibility of Blue Planet breaking free from Jupiter's gravity.

And what is the appropriate angle for the planetary engine to be deflected. However, the result of the calculation is despairing. Even if Jupiter's gravity returns to normal, there is no way for the Blue Planet to break through Jupiter's gravitational circle at the current angle. The final result will still be that it will be captured by Jupiter and become Jupiter's rings.

Liu Qi looked at the results of the supercomputer and the disappointed expressions on everyone's faces, and then said to Li Yiyi, who was in charge of operating the 550W supercomputer:

"Li Yiyi, do the math. Isn't Jupiter extracting the atmosphere from Blue Star? The oxygen in Blue Star's atmosphere and the hydrogen in Jupiter's atmosphere are gathering together. If they are ignited, they will definitely explode. Is it possible that this will push Blue Star to change its orbit and push it away from Jupiter?"

As expected, Li Yiyi, who originally had a somewhat desperate look on his face, immediately controlled the supercomputer to start calculating after hearing Liu Qi's words, and reported to Liu Qi while calculating:
"In the safe time before the Blue Planet reaches the Roche limit, Jupiter will absorb approximately 30 billion liters of oxygen from the Blue Planet!"

As for what is the Roche limit, this question is not a complicated one, because any celestial body with mass will always exert gravity on other celestial bodies, and gravity decreases as the distance between two celestial bodies increases. Similarly, gravity also increases as the distance between celestial bodies decreases.

Therefore, from the perspective of the celestial body that is subject to the force, the gravitational force exerted on a unit mass on its surface and a unit mass at its center of mass will be slightly different due to the different distances from the gravitational source.

Therefore, this gravitational difference is called tidal force. The reason why it is called tidal gravity is that the most typical example is between the moon and the blue planet. Because the blue planet can rotate once a day, the ocean on the surface of the blue planet is more susceptible to the gravity of the moon because the water in the ocean is liquid, which will cause tides!
Because the point on the sea level closest to the moon is naturally subject to greater lunar gravity than other places, the sea level in this place will be raised by the moon's gravity, thereby affecting the sea level of the sea water in other places, so there will naturally be the daily ebb and flow of the tide!

Therefore, for the celestial body that is subjected to force, the tidal force will stretch the celestial body along the direction of the line connecting the center of mass of the celestial body and the celestial body that exerts the force. The closer the two celestial bodies are to each other, the greater the tidal force will be, and the easier it will be for the celestial body to be pulled apart.

The tidal force will increase as the distance between the two celestial bodies decreases. So as the two celestial bodies gradually approach each other, if their density is large enough and there is enough space for the two celestial bodies to approach each other, there will be a limit distance within which one of the smaller celestial bodies will begin to disintegrate due to the tidal force.

When initially calculating this limiting distance, in order to make the model simpler, we may as well assume that the celestial body that is about to break up is only held together by gravity. In addition, we also assume that before the disintegration, the shape of the celestial body remains a perfect sphere. Then obviously, when the gravity of the surface matter of the celestial body is less than the tidal force, the surface matter will break away!

Therefore, the Roche limit is the distance at which the tidal force is equal to its own gravity, and the limit distance calculated by this method is called the Roche limit.

Of course, the Hippocrates limit is that celestial bodies with large mass and large gravity bully celestial bodies with small mass and small gravity, just like big fish eating small fish.

For example, between the moon and the blue star, the Roche limit is that the moon will be torn apart, and between the blue star and Jupiter, it is the blue star's turn to suffer, after all, Jupiter's mass is 318 times that of the blue star!

Of course, for solid celestial bodies, in addition to relying on gravity to hold them together, there is also stress bonding between materials. However, this bonding force is nothing compared to the strong gravity!

Then Li Yiyi continued to calculate how much energy could be released if these 30 billion liters of oxygen were mixed with hydrogen. Just a quick calculation made Li Yiyi's heart half full!
Li Yiyi murmured:
"The mass of one liter of liquid oxygen is 1.14 kilograms. The mass of 30 billion liters of liquid oxygen is 34.2 million tons of oxygen. One kilogram of hydrogen requires eight kilograms of oxygen to burn completely, so 34.2 million tons of oxygen is equivalent to the combustion of 4.27 million tons of hydrogen!" However, before Li Yiyi finished speaking, Liu Qi continued:

"One kilogram of hydrogen can produce 140 million joules of heat when it is completely burned, while one kilogram of TNT only produces 4.2 million joules of energy when it explodes. Therefore, one kilogram of hydrogen is equivalent to the explosion of 33 kilograms of TNT, which is equivalent to the explosion of 140 million tons of TNT! It is approximately equivalent to the explosion of nearly 2.8 Big Ivans!"

Sure enough, after Liu Qi came up with the results of his calculations, Li Yiyi was confused, because he was not sure whether an explosion with an equivalent of less than three Big Ivans could push the Blue Planet out of the orbit of Jupiter.

However, just when Liu Qi was somewhat confused about whether Liu Xiu's original proposal was correct or not, Li Yiyi suddenly said:
"No! We shouldn't have calculated it this way. We have calculated it wrong. Because in addition to the thrust of the planetary engine, Blue Planet also has its own speed. Maybe Blue Planet only needs a very small force to shift it a little distance to get rid of Jupiter's orbit!"

However, just when Liu Qi and Li Yiyi were wondering if they had calculated wrong, Liu Xiu made a video call through the restored network communication.

When Liu Qi saw Liu Xiu calling him via video, he immediately said:

"Captain, I thought of igniting Jupiter to push the Blue Star away, but after calculation, the explosion power generated by the oxygen absorbed by Jupiter is not enough to push the Blue Star to change its existing orbit!"

After Liu Xiu heard Liu Qi's words, he asked:

"So how did you calculate it?"

After hearing what Liu Qi said, he immediately told Liu Xiu the number that Li Yiyi obtained by using 30 billion liters of oxygen in the calculation.

However, when Liu Xiu heard Li Yiyi say that only 30 billion liters of oxygen were attracted by Jupiter, he felt something was wrong. Even though these 30 billion liters of oxygen were liquid oxygen and weighed more than 30 million tons, Liu Xiu still felt something was wrong.

You should know that the total weight of the entire Blue Planet’s atmosphere is only one millionth of the Blue Planet’s mass!
The atmosphere weighs approximately 600 trillion tons. Since the Blue Planet has now lost all surface plants, its oxygen production capacity has greatly decreased. Therefore, even if the oxygen content in the Blue Planet's atmosphere is less than 20% of what it was before, even if the oxygen content in the Blue Planet's atmosphere is only 10% now, the weight of the oxygen is still 600 trillion tons.

The energy generated by the explosion and combustion of 6 million tons of oxygen and Jupiter's hydrogen is equal to the equivalent of more than 240 trillion tons of TNT explosion, which is equivalent to the equivalent of more than 48 million Big Ivan explosions.

Of course, in fact, it is impossible for Jupiter to absorb all of the atmosphere of the Blue Planet, so it is naturally impossible to obtain more than 6 million tons of oxygen. However, it is definitely more than the mere 30 billion liters of oxygen calculated by Li Yiyi.
