Doomsday Bunker Upgrade

When the gravitational source exerts a force on the object, due to the different distances between the points on the object and the gravitational source, the magnitude of the gravitational force is different, resulting in a gravitational difference and a tearing effect on the object. This gravitational difference is the tidal force.

Amplifying this concept into the universe, tidal forces are everywhere.

When an object is massive enough, it is a source of gravity.

In space, whether it is the glowing sun or the blue star itself, or the moon revolving around the blue star, and many planets in the solar system, they all belong to the source of gravity.

However, under normal circumstances, tidal forces cannot shred an object. The simplest example is the Blue Star itself.

The blue star itself is affected by the dual gravitational sources of the moon and the sun. The tidal phenomenon on the blue star is the embodiment of the tidal force, but the blue star itself is not torn apart by the gravitational force of the sun and the moon.

But this time the meteorite that was going to hit the Blue Star was different.

First of all, its size is not large, but it is not small. After entering the Earth-Moon system, it was affected by the triple gravitational force from the moon, the blue star, and the sun.

Originally, in terms of the strength of the meteorite itself, it would not be torn apart by the gravity of the blue star, but who made it threaten the safety of the blue star, was drilled, and then the center was blasted?

The nuclear bomb detonated on the meteorite by the Federals did split the meteorite into two pieces, but it also destroyed the original internal structure of the meteorite.

To put it simply, the nuclear bomb detonated by the Federals not only blew up the meteorite, but also cracked the two parts that were blown up.

If you just leave it alone, it's fine, but when the meteorite's trajectory gradually approaches the blue star, it is more and more affected by the blue star's gravity, and even is simply captured by the blue star's gravity, the problem will come. .

It's like a sheet, which can't be torn by three people when it is in good condition, but when someone pokes a big hole in the middle of the sheet and tore the sheet into two pieces, the remaining piece is pulled by three people together. It is easy to shred the sheet along the cracked area.

So in the same way, the already cracked meteorite was subjected to the dual action of the blue star and the moon's gravitational force, coupled with the sun's gravitational influence, under the triple force, the originally cracked meteorite was torn into three parts.

It doesn't matter that the meteorites are torn into three pieces. If they continue to fly according to their previous orbits, it will be nothing more than three meteorites grazing the Blue Star.

But the problem is that when the meteorite was torn apart, it split into three parts and the weight was reduced, which made the three meteorites all captured by the blue star's gravity and flew towards the blue star.

On the cosmic scale, this matter is nothing but a few meteorites. Whether it is for the moon or the blue star, it is just a trivial amount of dust.

In fact, meteorites ranging from dozens to hundreds of tons fall on the Blue Star every day, but most of them fall in uninhabited places or are burned by the atmosphere before they land, and can really fall to the surface to form The number of hits is very small.

So the matter of meteorite impact, from the perspective of the universe, is really not a problem.

But from another point of view, the meteorite impact is about to die.

Modern human civilization is not bad, technology has climbed to a certain level, and human beings have begun to set foot outside the home planet. They also have a certain ability to withstand and defend against disasters of this level, and they can more or less save a little human beings in the face of disasters. The spark of civilization.

But what if the meteorite impact occurred in the past when human technology was less developed?

There is no need to push it forward for too long. It was only two hundred years ago in the eighteenth century. If a meteorite impact of the current scale occurred, then human civilization could just like dinosaurs, leave the keyboard with both hands and type GG.

Because with the technological level of the steam age two hundred years ago, it is simply unable to deal with such a disaster, and it is impossible to even dig a shelter.

However, even though modern human civilization has gradually begun to have the power to deal with such disasters, our ability to deal with disasters is still limited.

The rescue operation that gathered almost all the resources on the Blue Star was almost half successful, but now the meteorite that should have been pushed out of the impact orbit was not only pulled back by the Blue Star's gravity, but also split into three pieces. The leaders of various countries who knew about this matter instantly pumped up their blood pressure and their heart rate jumped to 120.

We haven't finished the four-kilometer piece, and now there are three more five-kilometer pieces. All the previous efforts have been in vain, and the crisis that mankind is facing has not eased in the slightest, but has become more serious.

Faced with this situation, leaders of various countries want to scold: What a fool!

But now that the four meteorites are smashing towards the Blue Star, it is impossible for them to give up blocking and raise the middle finger when the meteorite falls, so although they really want to quit, leaders of various countries still hold an emergency meeting to discuss How to deal with the immediate crisis.

"At present, four meteorites are flying over the blue star at a speed of 11.5KM/S. If there is no accident, they will hit the blue star in a few hours." A scientist from the United Nations action team was holding a report to the blue star. The leaders of the participating countries reported that in addition to reporting the time of the meteorite impact, he also gave the location of the meteorite impact: "According to orbital calculations, the location of the meteorite impact is likely to be North America and the Pacific Ocean."

Scientists did not say the disaster caused by the impact, because everyone knows that if all four meteorites fall, then there is no need to think about what will happen in the future. Human beings will most likely be extinct like dinosaurs.

So the top priority is to find a way to stop these four meteorites and prevent them from hitting the blue star.

At least not letting them all fall off.

"What other way do we have to intercept those meteorites?" Facing such a crisis, he was the first to ask. At this time, only the leaders of the top five Blue Stars were able to consider interception.

"In fact, we have nothing good to do. In these few hours, even if we want to launch the spacecraft and then perform the interception mission, there is not enough time, there is no time to refuel, and there is no ready-made spacecraft." The British leader was in a very heavy heart at this time, and the expression on his face was also a look of despair.

As an island country, Britain has neither enough depth nor enough resources, and its ability to respond to such a world-class disaster is really limited.

However, the leader of Lucia had a different opinion at this time, he said very firmly and forcefully: "We still have a last resort! Our Lucia spacecraft is still in space, and with them there are more than 20 launched by us. A nuclear bomb! Enough to shatter these meteorites with these nuclear bombs!"

The words of the leader of Lucia made everyone's eyes light up. This is indeed their last resort, and it is the only good news at present.
