United Nations International Minor Planet Early Warning Team.

Now, it's no secret that 2024GY48 is approaching/approaching Earth. Observatories around the world, including aerospace agencies, non-governmental astronomy enthusiasts, and even individual observers, as long as they are located in the Northern Hemisphere, can use astronomical telescopes to see the white dot reflected by the sun at night. It was a spot of light that did not flicker, pale in color, and if the telescope magnification was large enough, it could see the light and dark changes between the light and dark of the sunlight across the cold ravine, and these alternating shadows seemed to grow from the blood in the pupils of the day and night travelers.

The United Nations International Minor Planet Warning Team has made it clear that 2024GY48 is coming to the Earth with a 98% chance of impact, based on the observational data provided by member states (especially the data provided by the Purple Mountain Observatory in China).

The leader of the group made similar remarks in a television interview. He said that this is the first time that humanity is facing a crisis greater than a world war, but we are fully prepared. Since God has endowed mankind with wisdom, he will not destroy it easily.

Of course, the reason why the person in charge made such a confident and generous statement was not just to reassure people. Preparing for what would happen sooner or later when an asteroid kissed the Earth had been prepared for half a century ago. For example, destroying it with a package of nuclear bombs; Use a solar sail to increase the thrust of the unilateral solar wind (the force generated by photons in solar radiation on the blocker) to deviate from its path; Propelling an entity with a rocket to knock a meteorite off course like bowling; Install a high-power rocket directly on the surface ....

Many of the schemes were put forward after modelling meteorites, but in reality, most of them did not work. For example, the problem of scattered debris after destruction; Rotating meteorites, fixed azimuth problems of solar sails; Bowling ball impact and high-power rocket pushaway advance (since the mass of the man-made impactor is insignificant compared to the asteroid, the deflection angle that can be produced is very small, generally one ten-thousandth of a degree. The opposite side of this angle is the diameter of the Earth, so the edge should be long enough so that the extension of the meteorite path does not coincide with the Earth. This lead time generally takes more than 20 years) and so on.

After numerous simulations and revisions, the most accepted approach is the "push-away" scheme of the nuclear bomb. The Committee on the Outer Space, a coalition of the leading members of the United Nations Security Council, has begun preparations for a "push-away" program, which is partly a space-drowning drone with one or more nuclear bombs. The flying robot comes with a spraying device that, when flying side by side with a meteorite, the giant spray gun first sprays a mercury-like reflector at the target. After the spraying is completed, the no/man/machine performs a suicide dive and detonates the nuclear bomb at the same time.

The explosion of a medium-yield nuclear bomb can produce radiation forces orders of magnitude greater than that of an artificial bowling ball or a high-powered rocket, which is enough to send 2024GY48 away from Earth and Moon ten miles away. Moreover, the reflector reduces the absorption of explosive energy by the meteorite itself, which can improve the efficiency of thrust reversing.

Materials Testing and Analysis Laboratory of Nantian University in a city in China.

Two days later, the old professor pushed open the door of the laboratory, and the director had a depressed face and bloodshot eyes, and he stayed up all night.

"I did a re-analysis of the electron probe, and I didn't get even half of the diffracted rays, where the hell did you get this thing? I've been working on materials for 36 years and I've never been in a situation like this. ”

"Did you try the laser?" The old professor answered by asking questions, avoiding questions that could not be answered yet.

"Tried. I put the crystal in the focal point of all the holes and turned the power up to 90%, do you know how hot it is at that point? ”

"It can't be higher than the sun, right?" This old professor really doesn't know.

"When the focal point reaches 10 times the temperature of the sun's core, anything in the world, close to the point, will immediately vaporize, but crystals do." The director still couldn't believe the scene, and he was looking for the right words to explain his feelings.

"But it's intact, isn't it?" The old professor took it for him.

"It's not enough." The director is like telling a fairy tale to a child: "It's a vampire. All the energy is like a black hole injected, all of which has gone and never returned, and what is even more incredible is that the surface of the crystal actually maintains its original temperature. ”

"Did you take the temperature?" The professor frowned.

"Measured, room temperature."

"What about quality?"

"No change."

"That's weird. Suppose it has a structure that absorbs energy in one direction, but any object with a three-dimensional structure should obey the law of conservation of mass and energy. Even if it's a vampire, if you suck something in, it should gain weight, huh? ”

"It could really be a ghost, a ghost from an outer high-dimensional space." The director's voice was so light that it seemed to be talking to himself, which was a bit infiltrating.

"You say this stone is from a non-three-dimensional space?" The old professor laughed, as if he was laughing at himself, and as if he was laughing at the incident itself.

"This is the only explanation at the moment, otherwise any existing laws of physics would not make sense." The director spread his hands helplessly.

"You mean to say that the energy that was sucked away went to another dimension?"

"Is there a better explanation?"

"Then why only absorb energy and not matter?" The old professor reacted suddenly.

"Although energy and matter can be converted by the mass-energy equation, their properties are completely different. Energy is unrivaled in its penetrating and conductive properties, and it is easy to decompose into tiny units, or even into quanta; There are also advantages in terms of mass, such as a photon that can travel at the speed of light despite the theory of relativity, but it is difficult for matter to do this. It's no wonder that some scientists predicted that if time travel could be realized, the first traveler would likely be a wave of energy. Now it seems that this makes sense. "The director is engaged in materials, and the morphology of matter is his strength.

"Can you be more explicit and direct?" The old professor studied biology, which was something that could be seen and touched, and he only remembered Einstein's words about quantum physics: God doesn't roll dice. But what this junior said just now was like rolling a dice in his brain, and the crystal clear but opaque crystal was like God's dice shaking in front of his eyes.

"I mean, the reason why we don't absorb matter, we only absorb energy, because the crystal is so small. If there's a big crystal, or thousands of these crystals combined, it might be able to suck your whole body in. Got it now? "The director felt that the old professor didn't trust him, and every time he mentioned the origin of the crystal, he avoided the topic.
