"Four Eyes, what is gravitational binding energy?"

Niu Dazhi reached out and patted Lang Xiaonian on the shoulder, deciding to ask a very nutritious question.

"Gravitational binding energy, also known as gravitational binding energy, how to say it......"

Lang Xiaonian thought about it, clenched his hands into fists, and explained: "For example, there is a gravitational force between my two fists, but it is too small to be ignored.

"There is a gravitational attraction between all objects, the earth, the moon, all the stars in the universe, because of gravity, they are combined into a spherical shape.

"The star is bound by gravity into a sphere, and if you want to disassemble a star into pieces, you need to have a force to do the work against the gravitational force in the star.

"There is a critical value for the energy expended to disassemble a star into pieces, and this critical value is the gravitational binding energy.

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

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

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

"One by ten twenty-third joules." Lang Xiaonian repeated the result he had just calculated, "1×10^23 joules".

Niu Dazhi looked at the ceiling, his fingers moved around, and muttered, "If there are 23 zeros, what is the kinetic energy that Fang Yuan played last time?" It seems to be 25,000 Jingjiao, right? ”

"Yes, 2500000 Beijing joules, 2.5×10^20 joules." Eve chimed in.

"Wo Le slot! That's not a difference of three zeros, it's still a joke. I'd better lie down. Niu Dazhi heard that there were three zeros, and immediately lay back down.

"It's not like that......"

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

"Even if the kinetic energy is not reached, there is another way.

"Like knocking an asteroid out of its original orbit.

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

"If it is only blown in half, the energy required is less than the gravitational binding energy."

Zhao Anya clapped his palms and cheered up: "Okay, everyone has to believe in our strongest human beings." Moreover, you may not be able to see that Fang Yuan is too much stronger than the last time he sank the continental plate. ”

Han Youwei thought about it for a moment and said solemnly: "We can't put all the pressure on him alone. I asked for a waitlist plan, and even if I risked my life, I couldn't get the Pegasus fleet to come. ”

With the current level of science and technology of human civilization, it is impossible to compete with the Third Fleet of Pegasus of the Palese civilization.

After all, it was a fleet that could destroy stellar civilizations.

Therefore, the Third Fleet of Pegasus, as long as it passes through the stargate, it means that the end of mankind has come.

Look at it from the height of civilization.

If sacrificing the military research class, or even everyone in the expeditionary fleet, can destroy the stargate, it will be worth it for mankind.

Those who understand this truth know that no matter what kind of sacrifice is made, they cannot back down in this matter.

Zhao Anya glanced at the figure who was rushing towards the asteroid, and nodded in agreement with Han Youwei's application: "Okay, carry out the second plan." ”

Han Youwei nodded heavily and ran to the hatch.

……

Fang Yuanquan's ability exploded, rapidly increasing his speed, and rushed towards the star body with a diameter of more than a thousand kilometers.

The speed soared rapidly, gradually approaching the limit of 1% of the speed of light, under the ultra-high physical attributes, and the star power of planetary level Lv.9.

After exceeding the speed of light by 1%, it continues to soar, eventually reaching the speed of 1.2% light, heading towards the asteroid.

The asteroid is very large, reaching 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 Cannon, but it still maintains an intact star structure and has not broken apart.

The function of the Gamma Star Destroyer Cannon was originally to kill the life forms on the planet, not to blow them up.

As a result, the asteroid is used as a cover against the Gamma Star Destroyer, even if it has turned into a fireball.

Fang Yuan wasn't sure what kind of effect his full punch would have on this asteroid.

However, after the physical strength reaches the stellar level, a strong self-confidence is invisibly generated.

This feeling of power is very strange.

When Fang Yuan looked at this asteroid, he faintly felt a sense of power that could destroy it.

Therefore, without precise calculations, it was decided to spell this one.

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

In the Warframe Support System, the numbers on the speedometer are constantly jumping.

However, the average is at 3600km/s, which is roughly equivalent to 10,000 times the speed of sound.

Not only that, but the body mass has also reached its highest level ever.

Since the body attribute has exceeded 8000 points, the changes brought by the continuous improvement of the attribute have become more and more obvious.

Especially physical attributes.

After the body exceeded 8,000 points, the weight began to increase at a rapid and exaggerated rate.

In particular, bone density even has a tendency to develop towards a strong nuclear structure.

When the Physique stat exceeds 10,000 points, this increase becomes even more exaggerated.

As a result, from then on, Fang Yuan had to release his star power at any time to remain suspended, so as not to step on the concrete floor.

When the physical attribute reached 12,160 points, the net weight of the body measured during the physical examination had reached 25 tons, which was about the same as a tank.

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

Therefore, Fang Yuan's whole body armament has now reached the 10,000-ton level, and it has not yet reached the limit.

This is probably the real difference between a stellar and planetary star.

Fang Yuan's physical strength had already entered the stellar realm in advance, so when he saw a huge star, he was still confident.

At 10,000 times the speed of sound, Fang Yuan crossed a distance of hundreds of thousands of kilometers like lightning, rushing towards the asteroid, his whole body power exploded, and he let out a loud shout and blasted out the dark matter dragon fist.

Boom!

Roar!

The dragon roared and shook the sky, and the violent dragon-shaped fist was shot through the heavens and the earth, like a violent torrent, blasting into the flaming star.

Boom!

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

The star shook violently and was pushed backwards by a huge kinetic energy.

Immediately after that, the first crack opened on the surface of the star, and the crack quickly grew larger.

And then there's the second, and then the third......

In the blink of an eye, the star body split apart and exploded into cosmic dust, large and small, spraying in the direction of the stargate in the shape of a funnel.

The picture is spectacular, like a brilliant fireworks on a cosmic scale.
