"Four eyes, what is gravitational binding energy?"

Niu Dazhi reached out and patted Lang Xiaonian's shoulder, and decided to ask a very nutritious question.

"Gravitational binding energy, also called gravitational binding energy, how to put it..."

Lang Xiaonian thought about it, clenched his fists and touched them together, and explained: "For example, my two fists, there is gravitation between them, but they are too small to be ignored.

"Gravity exists between all objects. The earth, the moon, and all the stars in the universe are formed into a spherical shape because of gravity.

"A star is bound by gravity into a sphere. If you want to disassemble a star into pieces, you need a force to do work against the gravity of the star.

"The energy consumed by disassembling a star into pieces has a critical value, and this critical value is the binding energy of gravity.

"To put it simply, gravitational binding energy is the sum of energy that condenses matter into stars.

"To break the gravitational structure of a star, the energy required must be greater than or equal to the gravitational binding energy of the star."

Niu Dazhi looked very understanding, nodded and said, "What did you say about the gravitational binding energy of that asteroid?"

"One times ten twenty-third square joules." Lang Xiaonian repeated the result "1×10^23 joules" calculated just now.

Niu Dazhi looked at the ceiling, moved his fingers, and muttered: "If there are 23 zeros, what was Fang Yuan's kinetic energy last time? It seems to be 25,000 Jingjiao, right?"

"Yes, 250 million Jing Jiao, 2.5×10^20 Jiao." Eve interrupted.

"Fuck me! That's not a difference of three zeros. It's a game. I'll lie down." Niu Dazhi heard three zeros and immediately lay back.

"not like this...."

Han Youwei explained: "In fact, kinetic energy impact is very complicated. Simply comparing gravitational binding energy is indeed a way, but in fact, the real situation is much more complicated.

"Even if the kinetic energy produced does not reach the critical point of gravitational binding energy, there can be other ways.

"For example, knocking an asteroid out of its original orbit.

"Or by choosing different focus points, blast the asteroid in half.

"If it's just blasted in half, the energy required? Is less than the binding energy of gravity."

Zhao Anya clapped her palms? Cheer up: "Well, everyone must believe in our strongest man. And? Maybe you can't see? Fang Yuan is much stronger than the last time he sank the continental plate."

Han Youwei think about it? Solemnly said: "We can't put all the pressure on him alone. I applied for an alternate plan, even if I fight for my life, I cannot let the Pegasus fleet come over."

With the current technological level of human civilization? It is impossible to compete with the Pegasus Third Fleet of the Palestine Civilization.

After all, that is a fleet that can destroy stellar civilization.

Therefore? Pegasus Third Fleet, as long as it passes through the star gate, it means the end of mankind has come.

From the perspective of civilization.

If you sacrifice the military research team or even the expeditionary fleet owner? Can destroy the star gate? It is also worthwhile for mankind.

Anyone who understands this principle knows that no matter what kind of sacrifices they make in this matter, they cannot shrink back.

Zhao Anya glanced at the figure who was rushing towards the asteroid? Han Youwei's application was nodded and agreed: "Okay, execute the second plan."

Han Youwei nodded seriously? ran to the hatch.

...

Fang Yuanquan's supernatural power exploded, rapidly increasing his speed? He rushed towards the star with a diameter of more than one thousand kilometers.

The speed soars rapidly, gradually approaching the limit of 1% speed of light? Under the super-high physical attributes? and the star power of the planet Lv.9.

After the speed exceeds 1% of the speed of light? Continue to soar, and finally reach 1.2% of the speed of light, rushing to the asteroid.

This asteroid is very large, one-tenth the diameter of the Earth.

As a result, the asteroid has turned into a blazing fireball under the bombardment of the gamma star destroyer, but it still maintains a complete star structure and has not broken apart.

The function of the Gamma Star Destroyer was originally to kill the life forms on the planet, rather than explode the stars.

Therefore, this asteroid is used as a shelter against the gamma star destroyer, even if it has become a fireball, it can still function.

Fang Yuan was not sure what effect his full punch would have on this asteroid.

However, after the physical strength reaches the constant star level, a kind of strong self-confidence is created invisibly.

This feeling of power is very peculiar.

When Fang Yuan looked at this asteroid, there was a faint sense of power that could destroy it.

Therefore, without accurate calculation, I decided to fight this one.

Moreover, there is no time to calculate step by step now.

In the armor assist system, the numbers on the speedometer keep beating.

However, the average is 3600km/s, which is roughly equivalent to ten thousand times the speed of sound.

Not only that, but the body mass has also reached its peak state ever.

Since the physical attributes exceeded 8000 points, the continuous improvement of attributes has brought more and more obvious changes to the body.

Especially the physical attributes.

After the body surpassed 8000 points, the weight began to increase in a rapid and exaggerated range.

Especially bone density, there is even a trend toward a strong nuclear power structure.

When the physique attribute exceeds 10,000 points, this increase becomes even more exaggerated.

As a result, Fang Yuan must release star power at any time to stay suspended so as not to step on the concrete floor.

When the physical attributes reached 12,160 points, the net weight of the body measured during the physical examination had reached 25 tons, which was similar to a tank.

The increase in body strength allows the weight of the body armor to increase exponentially.

Therefore, Fang Yuan has now reached the 10,000-ton level, and has not reached the limit.

This is probably the real difference between a constant star and a travel star.

Fang Yuan's physical strength has entered the constant star realm ahead of time, so seeing a huge star still has reasons for confidence.

At tens of thousands of times the speed of sound, Fang Yuan dashed across hundreds of thousands of kilometers like lightning, rushing towards the asteroid, his whole body exploded, shouted, and blasted out the dark matter dragon fist.

Bang!

Roar!

The dragon shook the sky, and the violent dragon-shaped fist punched through the sky and the earth, like a violent torrent, crashing into the blazing star.

Bang!

The terrifying fist kinetic energy penetrated into the star and burst open.

The star shook violently and was pushed back by the huge kinetic energy.

Immediately afterwards, the first crack opened on the surface of the star, and the crack grew rapidly.

Then comes the second and third...

In the blink of an eye, the star fell apart and burst into cosmic dust of various sizes, spraying in the direction of the star gate in a funnel shape.

The picture is spectacular, like a splendid firework on a cosmic scale.
