Tracing China: Through history, dialogue between ancient and modern

Chapter 232 Gamma Ray Burst

1 years of future time and space.

Three men and women wearing high-tech battle armor flew across and landed beside Lin Feng with respectful expressions.

Three at the moment.

They didn't know that the handsome young man in front of them was their ancient Chinese.

"Sir, thank you very much, thank you for taking action at a critical moment, this time you really saved our human civilization..."

"My name is Tan Lu, thank you sir for saving my life..."

"Hello, my name is Long Xiangyu, and I am the commander of the twelve zodiac mechanical dragons..."

Two men and one woman opened their mouths, and there was a burst of sincere gratitude inside and outside the words.

of course.

Their faces were also full of confusion, obviously they didn't know where Lin Feng came from.

Because at the highest level of the elite of Chinese human civilization.

They have never seen Lin Feng.

Lin Feng looked ahead and said, "Long Xiangyu, why are you here fighting fiercely with this group of silicon-based alien civilizations?"

Perhaps Long Xiangyu was worried about angering Lin Feng, so he didn't ask any further questions, and explained the situation in detail.

It is said that thousands of years ago, they achieved great results in the research of dark matter and antimatter, and finally achieved the seventh cosmic speed, and thus gained the ability to enter and exit black holes. Beyond the boundless starry sky.

As a result, the most mysterious "white hole" astronomical landscape was revealed.

After countless years of unremitting efforts, human civilization has finally discovered a "white hole" outside the visible universe!
Everyone was so excited.

I feel that from the relationship between black holes and white holes, we may be able to find the relationship between the baby universe and the mother universe.

It can even be truly confirmed whether there is a Yang universe and a Yin universe.

But who ever thought.

Just when they came from a long distance of trillions of light years, they discovered that there was already a super civilization on the periphery of this "white hole".

And they have monopolized this vast starry sky through their own technology.

Countless astral life forms around were brutally killed by this super alien civilization.

even.

The aliens of silicon-based life have built layers of starry sky networks to shield the inside and outside.

Human civilization came here with the control of starry sky mechanical giants, with sincerity, thinking of friendship and mutual assistance.

As a result, these extraterrestrial beings are extremely murderous, and once anyone approaches, they will absolutely kill without mercy.

During that time, human civilization killed and injured tens of thousands of people, as well as countless technological machines.

Humans are not vegetarians either!
Since.

The two sides began to fight openly and secretly, and began an endless fight to the death.

At the beginning.

Human civilization is invincible, but with the passage of time, human civilization has accumulated a lot, and after achieving breakthroughs in key technologies, it has the capital to compete with alien civilization.

Before today's decisive battle.

In fact, there have been hundreds of major conflicts between human civilization and alien civilization, and each time both sides suffered heavy losses.

……

Listen to these words.

The audience who are watching the program are thinking about the first question, what is the seventh speed of the universe?

About this question.

Lin Feng could only shake his head, because he had only heard of the sixth cosmic speed.

The first cosmic speed refers to the speed at which an object moves in a circle close to the surface of the earth (it is also the minimum launching speed and the maximum orbiting speed of an artificial earth satellite), and its speed is 7.9km per second.

The second cosmic speed refers to the minimum initial speed required for an object to completely escape the gravitational shackles of the earth and fly away from the earth, and its speed is 11.2km per second.

The third cosmic speed refers to the minimum initial speed required for an object launched on the earth to escape the gravitational shackles of the sun and fly out of the solar system, and its speed is 16.7km per second
The so-called fourth cosmic speed refers to the minimum initial speed required for an object launched on the earth to break away from the gravitational bondage of the Milky Way and fly out of the Milky Way, which is about 110-120km/s, which refers to the navigation speed required for most places in the Milky Way .If the rotation speed of the solar system around the center of the galaxy is fully utilized, the minimum sailing speed can be 82km/s.Since humans know very little about the Milky Way, the mass and radius of the Milky Way cannot be valued, and it will take a long time for this number to form a public opinion.

The fifth cosmic speed refers to the minimum speed of the spacecraft launching from the earth and flying out of the local group of galaxies. All the galaxies in the local group of galaxies cover an area with a diameter of about 1000 million light-years. According to this calculation, it takes 1500-2250km/s It can only fly away at a high speed. This speed cannot be achieved at the current level of human scientific development. It will take at least decades or even hundreds of years to reach this speed.

The sixth cosmic speed refers to the minimum speed at which a spacecraft launches from the earth and flies out of the supercluster of galaxies. The diameter of the supercluster of galaxies is about 1 to 2 million light-years. According to this calculation, there is no need to consider energy consumption, etc. Under the influence of a series of conditions, it is theoretically necessary to approach the speed of light to fly away.

Yes.

For modern technology level.

It is still difficult to understand the sixth cosmic velocity, even in the academic circles of astronomy and physics, it is actually controversial whether the sixth cosmic velocity exists.

Let alone to understand the speed of the seventh universe.

In the lens.

Lin Feng asked, "Where did your spacecraft end up in the black hole?"

Long Xiangyu, the leader of the speaking team, pointed to the distance and said, "The black hole rushed in, and finally flew out of the white hole. Under the backlog of two kinds of negative and repulsive forces, the aircraft was almost turned into ruins, but our personnel still survived. "

"Eh!"

Another team member named Chen Chao sighed, "It's a pity that the survivors were all killed by these aliens."

Tan Lu said angrily, "All our scientific research results have been stolen by them."

Is that so?
Lin Feng said, "How can a terrifying celestial black hole communicate with an absolutely rare white hole?"

Long Xiangyu explained, "This is temporarily unknown, maybe it's the work of alien civilization."

Unspoken.

Those aliens with silicon-based life forms on the opposite side are planning a big chess game in the universe.

Intent to control this dark and cold cosmic world.

Lin Feng asked again, "You have inherited ancient Chinese war wisdom, why can't you beat each other?"

The so-called Star Wars.

In Lin Feng's eyes, can the ancient war strategy be used?
If you can't fight clearly, you won't hide your position?You won't draw from the bottom of the pot?You won't steal the day...

But Long Xiangyu shook his head and said, "Sir, we have indeed practiced thousands of ancient tactics, but they were all defeated by the opponent."

a force?
What super cards do these alien civilizations have?
Tan Lu continued, "Sir, they can control the absolutely terrifying "Gamma Ray Burst"!"

Lin Feng, "..."

He froze in place.

why?
Because this knowledge point is beyond his cognition!

He, an ancient man from 1 years ago, a Chinese ancestor from 0222, has never heard of him!

Maybe noticed this.

Tan Lu, who was wearing a set of technological battle armor, gave an explanation again, or popularized knowledge.

"Weight ray burst."

Also known as gamma burst, it is a phenomenon in which the intensity of gamma rays from a certain direction in the sky suddenly increases in a short period of time, and then rapidly weakens, with a duration of 0.1-1000 seconds.

It is said that gamma bursts were discovered in the 60s, in the modern era of information-based Blue Star.

In fact, people do not understand its essence very clearly.

It can only be confirmed that it is an eruption process occurring in a stellar-class celestial body on the cosmological scale.

Gamma-ray bursts are the most violent explosions to occur in the universe, theorized to be produced by the collapse and explosion of massive stars as they run out of fuel, or by the merger of two nearby compact stars (black holes or neutron stars).

Gamma-ray bursts can be as short as a thousandth of a second and as long as several hours, releasing huge amounts of energy in a short period of time.

If compared with the sun, it releases in a few minutes the equivalent of trillions of years of sunlight, and the energy of a single photon emitted is usually hundreds of thousands of times that of typical sunlight.

More serious.

Through certain calculations, it is found that powerful gamma-ray bursts can kill a certain range of life in the universe, and what is even more deadly is that gamma-ray bursts still occur regularly, which is bad news for life in the universe, because this Circumstances can prevent cosmic life from evolving into advanced species.

In other words, gamma-ray bursts may have cleared about 90% of the galaxy space, and the Milky Way will also be impacted by gamma-ray bursts. Life on earth may face a similar fate in the future.

Gamma-ray bursts come from stars that explode at the end of their lives, with powerful radiation that can damage DNA and cause planets to lose their atmospheres.

Some people have also discovered that gamma-ray bursts have hit the earth in the past 5 million years or so, leading to the extinction of a large number of lives. This explanation may explain why we still have not found other life in the universe. According to the results of sky survey observations, gamma-ray bursts have also been found Could render many galaxies lifeless.

The earth has also been "baptized" by gamma-ray bursts in the past years, but life on earth has survived tenaciously. This situation will also appear on other celestial bodies in the universe, which means that life on other celestial bodies may have a more tenacious vitality.

There are two types of Gamma-ray bursts, short bursts (less than 2 seconds) and long bursts (greater than 2 seconds).

Long bursts are generally considered "supernova analogues," marking the devastating outbursts of stars 50 to 100 times the size of our sun.When such a massive star explodes, it leaves behind a black hole and sweeps this information across the universe in the form of gamma rays.

……

After listening to this.

Lin Feng frowned and asked, "Is this gamma ray burst very powerful?"

He is thinking.

Can I stop this thing by relying on my "traceability system" skills?

Team leader Long Xiangyu nodded and said, "Strong, very strong, so strong that I can't find friends in this vast universe."

Lin Feng felt ashamed again, "..."

Can you speak more plainly?

I'm not your future super doctor!

The girl named Tan Lu is more reliable. She obviously knows that Lin Feng is not good at knowledge of celestial bodies and starry sky, so she came up with a more vivid metaphor.

As she said, the earth receives solar energy equivalent to less than 2 kilograms of matter per second.

The sun converts about 400 million tons of matter into energy every second. If all the energy emitted by the sun is aimed at the earth every second, the ocean will boil in less than 2 seconds; the ocean will evaporate in a little over 11 seconds; Get the earth out of a glass surface.

The sun emits enough energy in a year to blast the earth and push its debris out of the solar system more than 40 times.

Then a gamma-ray burst is equivalent to the sum of the energy released by 7 suns from birth to death, and the short burst is only 2 seconds.

If it is a long storm, it is even more terrifying, it can last more than ten minutes.

It has been recorded in history that a gamma-ray burst observed by scientists for 50 seconds released energy equivalent to the sum of 200 years of energy emitted by the Milky Way.
The numbers are not big.

But when it came to my mind, and I thought about it carefully, it made people feel scalp numb and feel chilly all over.

A gamma ray burst.

It is equivalent to the sum of the energy released by 7 suns from birth to death!
Who can stand it?
