Dimensional space that devours the starry sky

Chapter 138 The replay of the plot 6500 million years ago?

"Everyone!"

After Hong and Thunder God walked to the center of the conference hall, they stood still and looked around. Hong said in a deep voice, "I tell you a piece of sad news. The disaster and the end of the earth are coming!"

Swish!
The faces of everyone in the conference hall changed.

The person speaking in front of him is Hong, the strongest man of the human race!The first speaker of the God of War Palace!Undisputed No.1 in the world!
And such a strong person actually said that the end of the earth is coming!

"First Speaker, what happened?"

"Master Hong, what's going on?"

The few people who were closest to him asked questions one after another, with anxious and uneasy expressions on their expressions.

Hong shook his head, did not speak, and looked at a gray-haired old man in a white robe standing behind him, "Professor Flamingo, I will let you introduce the specific situation."

Swish!Everyone's eyes also looked over in unison.

The grey-haired old man's expression remained unchanged, he quickly walked up to the rostrum, and bowed to the people below.

Swish!
At the same time, a huge screen appeared right in front of the conference hall, and a PPT began to be shown on the screen. The gray-haired old man pointed to the PPT and said, "Now, everyone, please take a closer look at the screen above."

On the screen, a celestial system structure appeared, among which three specially enlarged photospheres were marked with the names of the sun, the earth, and Mars, so that everyone could know at a glance that this was the celestial system structure of the solar system.

Professor Flamengo pointed to one of the light balls and introduced: "This one represents our earth."

Then, the professor pointed to another smaller light sphere and said, "This one represents Mars."

"Earth and Mars are both planets orbiting the sun independently in their own orbits, and the distance between them is about 0.55 to 4 million kilometers. That is to say, when Mars is closest to Earth, the distance between them is about 5500 million kilometers, and the farthest distance is more than 4 million kilometers. The close contact between the two occurs about every 15 years, and this year, the distance between the two sides is about 9765 million kilometers," Professor Flamenco said on stage Talk eloquently.

Hong from the audience interrupted: "Professor, let's talk about the key points. I don't have time to listen to your popular science now."

Professor Flamingo nodded, and continued: "The current situation is like this. Our astronomical telescope observed that a huge asteroid, slightly smaller than the moon, with a radius of about 1500 kilometers, is now In the orbit of Mars, heading towards the Earth at a speed of millions of kilometers per hour!"

"According to our calculations, there are at most three more days! This asteroid will directly hit the surface of the earth! With the scale of this asteroid, once it collides head-on with the earth—"

A dynamic picture of the earth being torn apart after being hit by an asteroid was played on the screen, and everyone in the conference hall watched with bated breath.

Everyone was staring at the fragmented earth at the end of the dynamic image, and everyone was silent.

Hong said indifferently: "Professor, is there any way to resolve this crisis?"

The President of India on the side also asked: "Can a nuclear bomb be used to blow up this asteroid into pieces? If the equivalent is sufficient, it should be possible, right?"

Everyone stared at Professor Flamingo without blinking, wanting to hear his professional opinion, but they were also afraid of hearing a negative answer from him.

"According to the scientific analysis, if the yield of the nuclear bomb is sufficient, it is indeed possible to completely blow up this asteroid to pieces. But—" After hearing the first half of the sentence, everyone's hearts were relieved, and they could Just do it.

But the professor's words instantly lifted everyone's hearts.

"However, in order to completely blow up this asteroid to pieces, at least a TNT explosive with an equivalent of more than one billion tons is required. At present, all the nuclear warheads on the earth combined cannot reach this scale."

Everyone fell into silence. A nuclear warhead with a yield of billions of tons is completely unattainable with the current level of human technology. The level of technology contained in it requires at least a big step forward for human beings.

"And, most importantly, most of the power of nuclear bombs comes from shock waves, and most areas in the universe are in a vacuum state, lacking gas, dust and other media that can form shock waves. Therefore, if a nuclear bomb is detonated in the universe, the nuclear bomb's The power will also be greatly reduced."

Some people with poor psychological qualities already showed despair on their faces.

Hong Yi frowned and asked, "Then we really have nothing to do?"

"In fact, you don't have to be so pessimistic. There are still ways."

Professor Flamingo said with a smile: "Actually, with the current level of human technology, it is not difficult to blast it into pieces. You only need to gather all the laser cannons on the earth to one point, and use the maximum With a few rounds of volley bombardment, it will definitely be blown to pieces in a few times."

"After all, the characteristic of laser is to 'penetrate'. Especially for an asteroid like this, once the internal core is destroyed, a big explosion will occur and it will fall apart!"

Hearing this, some people breathed a sigh of relief, and smiles gradually appeared on their faces.

Isadona, the chairperson of the HR Alliance, said directly: "All the laser cannons under my HR Alliance are willing to provide them, and let the professor drive them!"

The leaders of the rest of the countries have also expressed their agreement, and are willing to provide all the laser cannons and corresponding energy to survive this crisis.

"but--"

Professor Flamingo hesitated a little, and slowly said: "But we still need to confirm what the material that makes up this asteroid is. If it is all formed by ordinary stones, then how difficult it is to smash this asteroid It’s not that big, you just need to set up a fort in space outside the earth and calculate the intersection point.”

"If there is a lot of metal in the interior of the asteroid, then"

Luo Zhe frowned, and asked, "So what? If the professor has any doubts, just ask, and we can discuss it together."

Hong said directly: "Professor, if you have any doubts, just tell me, I will take care of it for you."

The professor quickly waved his hand and said, "I don't have any doubts. It's just that if there is really a lot of metal inside this asteroid, even if we can blast it to pieces.

But according to its current speed and the relative distance from the earth, there will still be some debris that will continue to fly towards the earth according to inertia, and finally hit the surface of the earth! "

Luo Zhe frowned, and asked again: "If it is true that some planetary debris will directly hit the surface of the earth, what adverse effects will it have on the earth?"

"If some of the planetary fragments are too large, with a radius of several kilometers or even tens of kilometers, then when they hit the surface of the earth, the energy released after complete vaporization is enough to cause large tsunamis, earthquakes and volcanic eruptions, and make a large number of The dust enters the atmosphere, completely blocks sunlight, changes the global climate, and causes a nuclear winter."

"At that time, the end of the earth will really come!"

The professor shook his head and said: "You know, the Chicxulub impact event that happened 6500 million years ago, oh, that is, the meteorite that fell from the sky that caused the 'extinction of the dinosaurs' 6500 million years ago. crash event.

And the meteorite that hit the surface of the earth is estimated to be only ten kilometers in diameter.But it is such a meteorite, after the impact, the energy released by complete evaporation is as high as 5.0×10^23 joules, which is equivalent to more than 90 trillion tons of TNT explosives! "
