I ask you to build tractors, but you build rockets?

Of course, no one could answer David's rhetorical question. Seeing this, he came to his conclusion:

"Let's take a look at what happened on December 13, the day the first signal was intercepted. Gentlemen, you must remember it."

This date will be remembered as soon as I think about it, and Claire immediately replied:

"Nuclear bombs, two hydrogen bombs exploded."

Snapped!

David snapped his fingers:

“Yes, two hydrogen bombs exploded and we intercepted the first signal on the same day.

Although we intercepted another signal three days after the explosion of the third hydrogen bomb, if you think about it and found nothing in the past ten years, the correlation between the explosion of the hydrogen bomb and the signal is the closest. Otherwise, there is no reason why we have found nothing for so many years, but now we have found nothing. Can find things. "

"According to what you say, it should have sent such signals countless times."

Sullivan meant something. Humanity has conducted thousands of nuclear tests, large and small, in the last century. If there is any correlation, signals should have been sent frequently.

"Yes, but at that time we had too few detectors going to Mars, the working hours were very short, and the detection capabilities were not strong enough. By the time new detectors were sent there in the new century, nuclear testing around the world had almost stopped, and only a few limited The illegal test yield is also very small."

Sullivan and Claire looked at each other and reluctantly agreed with this statement.

Those detectors in the 20th century were very primitive and had no ability to intercept camouflaged signals. There were indeed no high-yield nuclear tests in the intervening 20-year gap, which also explains why later detectors could not capture any signals at all.

So there is one more doubt about this statement: why are nuclear explosions related to signals?

This question was not difficult for David, and he became serious:

“Although we know nothing about aliens or alien civilizations, from an overall perspective, what should be the biggest common denominator between any civilization, or within civilizations?

It's a disagreement! As long as it is not a group intelligence type, but a civilization like ours that is composed of individual intelligent entities, there will definitely be differences. And when these differences are too big to be resolved, what is the most likely result? "

"war!"

John blurted out that when differences between different groups reach a certain level, they can only enforce their will through the most violent means.

Although the others looked solemn, they nodded in agreement, especially many employees who worked in the Hexagon Building. They agreed with this statement very much.

The relationship between civilizations can only be friendly or hostile, so there must be the possibility of war. This should at least be a common law for most civilizations in the universe.

David was quite pleased with the response and continued:

"Yes, war, war never changes; just like us humans, from fighting with spears between tribes, to scimitars and armor as cold weapons, to the roar of cannons in the era of hot weapons, war will never stop. There has never been a day in the history of civilization without a war.

If we distinguish by energy, we can divide wars throughout the ages into three stages: the cold weapon age, the hot weapon age, and the atomic age.

In the initial era of cold weapons, humans had very little energy, and the most they could do was set off a fire.

Later, gunpowder changed everything in the era of hot weapons. The energy that humans can use for war has greatly increased. One battleship heavy gun is enough to level an entire football field, which was impossible in the era of cold weapons.

In the atomic age, the energy released by an atomic bomb explosion was higher than the combined energy released by all previous human wars. The most terrifying Tsar hydrogen bomb had an yield of 50 million tons. If it was used to clean up nuclear radiation, it could directly wipe out the island country. And this It is also far from reaching the limits of thermonuclear weapons.

If we want to observe the development of a civilization from a long distance - I mean a distance of more than light years, the simplest and most efficient way is to install an energy detector. When the energy released exceeds a certain threshold, We will know roughly what stage that civilization has developed.

If there is such a super civilization, in order to prevent enemies from suddenly developing around it, it can release such simple detectors everywhere. If there is an alarm, it can take a look and decide how to deal with it.

If human civilization develops to a certain height, it will inevitably consider interstellar defense issues, and the best defense is to nip danger in the cradle in advance! "

As David spoke, the expression on his face became more ferocious, as if he was that alien civilization full of malicious surveillance of humans.

“The range of power of an atomic bomb or hydrogen bomb explosion is not worth mentioning in the universe or the solar system, but as long as the sensitivity of the detector is high enough, it can still be detected through small gravitational fluctuations or abnormal electromagnetic radiation values.

The distance from the Earth to Mars is not too far. According to discussions among our technical experts, even humans are expected to realize this technology in a few decades, let alone alien civilizations. "

Everyone sitting there opened their eyes wide and felt shocked, not because it was too exaggerated, but because it was so possible, especially since it fit well with their way of thinking.

Energy theory is not a new idea. Some people have previously classified civilizations based on the scale of available energy, and this has been generally recognized by the scientific community.

This is a rule that humans have personally summarized: the higher the scientific development, the more energy can be utilized.

It is common sense that the most cutting-edge technology is used in war, so the theory of war energy is basically established.

Claire even thought of other places. In the past, some people had been worried that human beings' reckless radio signals would be discovered by aliens. In fact, this was unnecessary.

Not to mention how much effort it takes to decipher these mostly meaningless signals, these signals cannot be directly linked to war capabilities, and the basis for attitude selection between civilizations is the comparison of war capabilities.

You only need to confirm the level of the opponent's war potential to formulate the most reasonable response. After all, the laws of physics cannot be encrypted and are the easiest to perceive.

"Then we should prevent continued nuclear testing and prevent more nuclear bombs from exploding."

It was John who spoke. He instinctively did not want to be more exposed to the eyes of the "enemy". This feeling would make people very passive.

"It's too late."

David shook his head slowly:

"There have been countless nuclear tests in the last century, and the yield was much greater than now. Alien civilization must have known that we have entered the atomic age. If they are ready to intervene, then the Star Fleet may have already set off.

We don’t know when they are coming. We should work hard to develop our strength instead of burying our heads in the sand. This is meaningless. Maybe more explosions can make them face the power of mankind... Although this is also very difficult for a super civilization. ridiculous. "
