Why do stars have shorter lifetimes when they are more massive?

As we all know, stars are the products of interacting with each other and maintaining stability by relying on the outward radiation pressure generated by the nuclear fusion reaction that is constantly taking place inside the space and the inward squeezing gravitational force generated by the universe!

The greater the mass of the star, the stronger the gravitational pull, and the stronger the gravitational pull, the more "powerful" the star's material shrinks inward, and the greater the radiation pressure is needed to balance the gravitational pull.

And if you want a higher radiation pressure, you need to have a more violent nuclear fusion reaction.

The more intense the fusion reaction, the more material is consumed per unit of time.

No matter how massive a star is, there is a limit to the amount of material it can use to carry out nuclear fusion reactions. Once the material used for the nuclear fusion reaction is used up, it is not necessary, and once the hydrogen in the star is consumed by more than 30, the star will appear old, and the life of the star will enter the countdown.

So, the more massive the star, the shorter its lifespan.

That's why Bigfoot is 50 times more massive than the Sun and has a lifespan of only 80 million years!

Bigfoot is so massive that it has a short lifespan, less than 80 million years!

Even if it is short, once the lifespan is decided, as long as there is no accident, there will basically be no major changes, but now, the Manta Tower said that the life span of Bigfoot Star, which only has a lifespan of 60 million years, has swelled to 500 million years!

60 million years!

500 million years!

This made Xue Yu very shocked: "Barbarian Tower, why is this?" ”

"Hehe, because the mass of Bigfoot is decreasing all the time, and this decrease is not due to the consumption of the fusion reaction itself, but inexplicably decreasing.

As a result, the gravitational pull exerted on Bigfoot is also decreasing, and the nuclear fusion reaction inside it consumes less energy and matter.

And because this decreasing speed is much slower than the matter consumed by the nuclear fusion reaction of Bigfoot itself, the life span of the two is increased, and it has at least 500 million years to live! ”

There are two kinds of mass reduction in Bigfoot itself, one is an inexplicable reduction, and the other is a decrease in the nuclear fusion reaction itself.

Although the former is reducing the mass of Bigfoot, it is increasing the lifespan of Bigfoot from the side!

The latter is also reducing the mass of Bigfoot, but it is consuming Bigfoot's lifespan!

Increased life consumption of life!

Therefore, the lifespan of Bigfoot has increased from 60 million years to 500 million years!

Even, as the nuclear fusion reaction becomes less violent, the lifespan of the star itself has increased invisibly!

Xue Jun understands this reason, but what puzzles him is that how can the mass of Bigfoot Star decrease inexplicably?

Thinking of this, Xue Jun seemed to have thought of something, and his eyes couldn't help but widen: "Could it be that the Spirit Fruit Tree is consuming the mass of Bigfoot?" ”

"In the case of the right line, there are many possibilities!" Manta said: "But in connection with the current situation, there should be only this possibility!" ”

"So the spiritual fruit is on Bigfoot?" Xue Yu was overjoyed and urged: "Then you quickly find it out!" ”

"Don't worry, don't worry, take your time, if the Spirit Fruit Tree is really on Bigfoot, hehe, no one can snatch it away, it can only be in our bag!" Brute Tower Road.

"That's right!"

Xue Jun took a deep breath, suppressed the joy in his heart, and couldn't help but have a touch of sarcasm on his face: "I finally understand now, why would Carory tell me the whereabouts of the Spirit Fruit Tree so quickly, it turned out"

"What can I do if I tell you, he is not worried that you can take away the spirit fruit tree at all, nor is he worried that you can pick the spirit fruit, he has nothing to fear!"

Cybertron shook his head.

"Hehe, the Spirit Fruit Tree grows on Bigfoot, except for the sixth-level life that can manipulate space, who can pick it up? What is the difference between telling me and not telling me? Xue Yan shook his head, and the sarcasm on his face was even worse: "Caroli's abacus is clanging, but it's a pity that he still miscalculated, and he didn't know that I was still a space superpower!" ”

"Haha, this is called a thousand calculations, there will always be miscalculations, and it is also called losing the lady and breaking the soldiers! If Carory can bring Kadak and the others back, and then learn about your abilities from them, he will never tell you the whereabouts of the Spirit Fruit Tree in vain! ”

Cybertron laughed: "I can imagine now that once Carory learns the news, she will definitely vomit blood in anger!" ”

"Hehe, it doesn't matter if he vomits blood or not, who let him take advantage of me, but he didn't get any benefits, but not only did I surrender the 13th squadron, but also gave me the spirit fruit tree for nothing!"

Xue Jun laughed, and his heart was really happy!

Await!

Wait silently!

The Brute Tower is scanning, and Xue Yu is waiting!

Time passed slowly in this waiting, minute by minute, second by hour

Gradually, 3 hours passed, and the Brute Tower finally had an answer!

"Found it, haha, finally found it!"

The Brute Tower suddenly roared, and the strange scream of excitement began: "Spirit Fruit Tree, really Spirit Fruit Tree, good guy, it grows so deep, it's incredible!" ”

At this moment, Xue Jun had already been waiting for sleepiness, and was suddenly awakened by the roar of the barbarian tower, and the whole person was full of excitement, jumped up in an instant, and roared excitedly: "Where is it, where is the spirit fruit tree?" ”

"Hahaha, in a place you would never imagine!"

Manta manipulated the flying saucer to create a virtual projection of Bigfoot, and then cut Bigfoot in half from the middle to form an orange cross-section, and at this moment, on this orange cross-section, there is a green dot.

"Look, this is the location of the Spirit Fruit Tree!"

Pointing to the green dot on the cross-sectional map, Manta said with a smile: "It is located at a depth of 990,000 kilometers below the surface of Bigfoot!" ”

"990,000 km? So deep? ”

Xue Yu's eyes widened: "How high should the temperature be there, how can the Spirit Fruit Tree withstand it?" ”

The temperature on the surface of Bigfoot is as high as 8,000, 990,000 kilometers deep, how high should the temperature be?

"Hehe, it's about 24 million, which is not too high, and it is a little higher than the temperature in the center of the sun!" Manta said with a smile, the temperature in the center of the sun is 20 million!

Xue Yan blinked, was speechless for a long time, and only after a moment did he say: "I don't care how perverted the Spirit Fruit Tree is, Barbarian Tower, quickly tell me its exact location, I want to go in and pick the Spirit Fruit!" ”
