The headquarters was located at the European Space Center in Paris. The European Space Agency was founded in 1975 and is an inter-governmental organization dedicated to the exploration of space. It has 22 member states.
The Rosetta comet probe, which was deployed above Mars 'orbit, sent back satellite photos that showed a behemoth that humans could not imagine was slowly descending in a vertical spiral motion about 18,000 kilometers above Mars' orbit.
"Oh my god!"
The president of the European Space Agency covered his mouth with his hand.
The assistant at the side looked at the big screen in a daze and muttered,"Could it be that the Drake Formula was verified today?”
The president of the European Space Agency, Mr. Chris, the famous Astronomist, naturally knew about the famous Drake Formula in physics.
This was the answer to the more famous " Fermi Parabola."
One day in 1951, when Nobel Prize winner and physicist Fermi was discussing UFO and aliens with others, he suddenly said,""Where are they?"
This seemingly simple question was known as the Fermi Parabola.
The implication of the Fermi Paragon was that, theoretically speaking, humans could fly to various planets in the Milky Way in a million years. Then, aliens should have arrived on Earth as long as they evolved a million years earlier than humans.
In other words, Fermi's Parabola showed that this was the case.
A. Aliens do exist-scientific inference can prove that aliens evolved much earlier than humans, and they should have already arrived on Earth and existed somewhere.
B. B. Aliens do not exist-so far, no trace of their existence has been found.
The contradiction between A and B represented the contradiction between the overestimation of extraterrestrial civilization and the lack of relevant evidence.
Later, the mathematician Frank Drake proposed two equations, which were called the Drake formula.
1 is:N= Ang ×Fp×Ne×Fl×Fi×FC× TL [2]
Formula 2 is:N=R*×Fp×Ne×Fl×Fi×FC×L
Among them:
N represents the number of civilizations in the galaxy that may communicate with us
Number of stars in the Milky Way
The proportion of planets in a planet
The number of terrestrial planets in each planetary system
Fl. proportion of habitable planets with life evolution
The probability of fi evolving into a highly intelligent creature
FC The probability of intelligent life being able to communicate
fL The ratio of the duration of a technological civilization to the life cycle of a planet
The difference between Formula 2 and Formula 1 was that R* was used instead of NG, and L was used instead of fL.
R* is the average rate of star formation in the Milky Way
L is the lifespan of technological civilization
The Drake equation was seen as the first formal theoretical response to Fermi's Paragon. According to the calculation of the Drake equation, the number of planets with extraterrestrial intelligent life should be around 1 million.
And we can only come into contact with one alien life at any time.
Could it be that today, the only alien technology that theoretically existed that could make contact with Earth's civilization appeared?
What kind of changes would he bring to Earth?
This was the question in the minds of all astrophysicists.
All the countries on Earth that could observe outer space sounded the alarm at the same time.
The heads of state rushed to the space center.
........
Galaxy.
Tomcat and Zhao Xiaofeng, who had just woken up from hibernation, were discussing.
"Captain, I've just sent out a distress signal through electromagnetic waves and the mother planet Earth.”
Zhao Xiaofeng nodded and frowned.
He knew that it would take about four minutes to contact Earth through electromagnetic waves near Mars.
Including the round trip, it was a delay of about eight minutes.
He was now wondering why the space port that the Human Alliance had deployed above Mars had disappeared.
The images sent back by the Galaxy's infrared detector and thermal imaging sensor showed that Mars was now a dead, dark red planet. There were no signs of life.
As early as 600 years ago, the Human Alliance had begun to modify the ecological environment of Mars.
More than 200 years ago, the first batch of human immigrants arrived on Mars.
Could it be that something unexpected happened to the Human Alliance during his thousand years of interstellar travel?
Zhao Xiaofeng's heart sank.
"Captain, we have received a reply from Earth!”Tomcat reported in a strange voice,""However, the order of this information language is different from that of the Human Alliance!”
"Can it be broken?" Zhao Xiaofeng asked.
"This message seems to be using an ancient programming language called C that we eliminated thousands of years ago."
Tomcat replied with a frown.
"The content of the message is roughly-Hello! This is Earth. May I ask which star field you are from?”
