David's rhetorical question, of course, was unanswered, and it was only then that he came to his conclusion:

"Let's see what happened on the day the first signal was intercepted, December 13, gentlemen, you must remember."

This date is remembered only a little, and Claire immediately replies:

"Nuclear bombs, two hydrogen bombs exploded."

Syllable!

David snapped his fingers:

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

Although we intercepted the signal again three days after the explosion of the third hydrogen bomb, if you think about the previous ten years of nothing, the correlation between the explosion of the hydrogen bomb and the signal is the closest, otherwise there is no reason why we have not found anything for so many years, but now we can find something. ”

"If you say so, it must have sent such a signal countless times."

Sullivan meant that in the last century, there have been thousands of nuclear tests, large and small, and if there are correlated signals, they should have been sent frequently.

"Yes, but at that time, we had too few probes to Mars, the working hours were very short, and the detection capability was not strong enough, and by the time new probes were sent in the new century, the global nuclear tests had almost stopped, and the limited number of illegal tests had a very small yield."

Sullivan and Claire looked at each other, barely agreeing with the statement.

Those detectors in the 20th century were very primitive, how could they intercept camouflaged signals, and there were indeed no large-yield nuclear tests in the interval of more than 20 years, which also explains why later detectors could not capture any signals at all.

So this statement is still a doubt: why is a nuclear explosion related to a signal?

The question didn't bother David, and he began to get serious:

"Although we don't know anything about extraterrestrials, alien civilizations, but from a general perspective, what should be the greatest common denominator between civilizations, or civilizations, from a civilization in general?

It's a disagreement! As long as it is not a group intelligence, but a civilization like ours composed of individual intelligences, there will be disagreements, and when such disagreements are too large to be resolved, what is the most likely outcome? ”

"War!"

John blurted out that when the differences between different groups are so great that they can only enforce their will through the most violent means.

Others, despite their solemn faces, nodded in agreement, especially many of the staff who themselves worked at the Hexagon, who couldn't agree with the statement.

There will only be two kinds of relations between civilizations: friendly and hostile, so there must be the possibility of war, which should be at least the common law of most civilizations in the universe.

David was pleased with the response, continuing:

"Yes, war, war never changes; Just like us human beings, from the spears fought between tribes, to the scimitars and armor of cold weapons, to the roar of cannons in the age of hot weapons, wars never stop, and there has never been a day in the entire history of human civilization that there has not been a war.

If we distinguish by energy, we can divide the wars of the past and present into three stages: the age of cold weapons, the age of hot weapons, and the age of atoms.

In the early era of cold weapons, human beings had very little energy at their disposal, and at most a fire was the limit.

Later, in the era of hot weapons, gunpowder changed everything, and the energy that human beings could use for war was greatly increased, and a single battleship heavy gun was enough to raze the entire football field, which could not be done in the era of cold weapons.

In the atomic age, the energy released by an atomic bomb explosion is higher than the energy released by all previous human wars, and the most terrible Tsar hydrogen bomb has a yield of 50 million tons.

If we want to observe the development of a civilization from a great distance, I mean light years or more, the easiest and most efficient way is to place an energy detector, and when the energy released exceeds a certain threshold, we know roughly where that civilization has developed.

If there is such a super civilization, in order to maintain that there are no enemies around it that suddenly develop, it can completely release this kind of simple detector everywhere, and take a look at which one alarms and decide how to deal with it.

If human civilization develops to a certain height, it will inevitably consider the issue of interstellar defense, and the best defense is to strangle the danger in the cradle in advance! ”

As David spoke, the expression on his face became more and more hideous, as if he was the alien civilization full of malicious spying on humans.

"The range of power of an atomic bomb or a hydrogen bomb is not worth mentioning in the universe or in 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 anomalies in electromagnetic radiation values.

And the distance from Earth to Mars is not too far, and according to our technologist discussions, even humans are expected to achieve this technology in a few decades, let alone extraterrestrial civilizations. ”

Everyone sitting in the seat opened their eyes wide and their hearts were shocked, not because it was too exaggerated, but because it was too probable, especially since it was very much in line with their way of thinking.

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

This is the law that human beings have summarized themselves: the higher the development of science, the more energy can be utilized.

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

Claire even thought of other places, there had always been fears that human beings would be discovered by aliens because of their unscrupulous radio signals, but in fact it was unnecessary.

Not to mention how much effort it takes to debunk these mostly meaningless signals, these signals are not directly linked to the ability to war, and the basis of the choice of attitudes between civilizations is the comparison of war capabilities.

It is only necessary to determine the extent of the opponent's war potential, and then to be able to formulate the most reasonable response, after all, the laws of physics cannot be encrypted and are the easiest to perceive.

"Then we should stop the nuclear tests from continuing and not let more nuclear bombs explode."

It was John who spoke, and he instinctively didn't want to be exposed to the eyes of the "enemy" more, which 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 is much larger than it is now, and extraterrestrial civilizations must have known that we have entered the atomic age, and if they are ready to intervene, then Starfleet may have set off.

We don't know when they're coming, we should try to develop their strength instead of burying their heads in the sand, it's pointless, maybe blowing up more will still make them face up to the power of humanity...... Although this is also ridiculous for a supercivilization. ”
