Chapter 709 Civilization Quantity

"Well, it is true."

William has a little bit of agreed.

Before the "three bodies" came out, William, who had not passed, hopes that humans can find alien forces, race and civilization.

But after the "three bodies" came out, William only felt what pioneers and travelers launched by Nasa, it was simply a complete intelligence operation.

Send the detector to leave the solar system, leave, but also engraved on the Earth coordinates, and what is the operation of human DNA?

On-home delivery?

"Two-way foil ... two-way foil." At this time, Harxi is muffy itself, and then holds the right hand of William's left hand, and the appearance of the exciting look:

"After listening to this vocabulary, I finally understand why there will be many complete dark areas in the observable universe.

This is likely to be an attack measures for some higher civilizations, or the interstellar wars between two higher civilizations, resulting in a complete dark zone.

It is impossible to observe that there is no light to escape, or even black holes can not exist.

Just as the author of the "Star Boat Parachi", Robert Hein, Lein, took the lead in the science fiction, and the concept of power, orbital airborne.

Over time, our human science is really like "Star Ship", with tens of thousands of power, and orbit empty soldiers.

Sure enough, scientific progress will never be able to open the romantic ideas or ideas of those sci-fi writers.

You just told me "three bodies", I suddenly made me suddenly turned over. "

"..." See the appearance of Harcya, William feels that the head seems to be big, and then the face is helpless:

"Catherine, I don't think this kind of thing is worth having, if this universe really has a civilization with two-way foil ... Then our human and elite face them, is it not even a good anti-chance?"

"Hum ..." See William said his worries, Harxi also took the smile and said:

"You asked me before, how much is there in this universe, right?"

"Ok."

"This problem is so solved." Harcy said, from her lady's suit pocket, took out the ultra-thin transparent mobile phone of Anbrera Technology.

Touch the fingerprint unlock screen.

Open holographic projection, and then she took another, let a mathematical formula presented in front of her and William.

N = r ** fp * ne * fl * fi * fc * L.

Seeing mathematical formulas, William's headache is even more serious, and then the face is smirk to Harxi:

"Catherine, you help me explain what is this ... Since I have a high school mathematics class, I will never face mathematics after I have a pen on the ground."

"You don't have physical physics, mathematics mathematics ... Fortunately, Ivan and Ye Lianna did not follow you, otherwise it was abolished ..."

Hali made a look at William, then looked at the formulas in front of them, explained William:

"This formula is named Dreick formula, which is proposed by Frank Delhi in 1961 to calculate how many civilizations in the Galaxy system.

The N is obvious, is the number of civilizations in the Milky Way system.

R *, represents the production rate of appropriate stars, such as our sun.

The sun has a sufficient range of livable belts, age is also forty to five billion years.

Like our planet, we used to develop life in millions of years, and a star became a red superstar before this, or a super star explosion, then this star is not applicable.

According to the evolutionary model of the ancestors, there will be such a star in the Milky Way in the year of each east year.

That is, R * is equal to 1.

FP, is the value of how many large planets in the stellar system, such as our solar system, eight planets are 8.

But we cannot use the size and rules of the solar system to estimate the star system in the entire galaxy, so we cannot be determined by specific values.

NE represents the number of planets with life evolution, derivation, and development conditions in the planet of these stellar systems.

If you want to go in, such as the composition of the atmosphere, whether the asteroid will hit, day and night temperature difference, etc.

Fl represents a planet that meets the NE condition, it can evolve the present invention with DNA or genetic substance.

Fi represents a planet that meets the NE condition, it can evolve into a smart life, such as our human existence.

The FC represents the probability of the signal radio wave communication to the outside world to represent the planets that meet the NE condition. .

The last L, representing the average life of science and technology civilization.

For example, in 1893, Nichola Tesla first shows the wireless until now 134 Earth Year.

In other words, Tesla allows us to enter the era of science and technology civilization in the true sense. "

"hiss…"

After listening to a series of explanations in Harcy, William couldn't help but take a breath, and lifted the right hand to cover your forehead, trying to let yourself awake.

a bit sleepy.

Just like the mathematics class, the hypnotic effect of mathematics teachers is much better than any sleeping pills.

"Oh ~." Seeing William's eyes and appearance, Harxi couldn't help but smile, then simply explained:

"Before you have not met the harvest, the mammoth and the Star League, all of the above formulas are 0, then our earth is the most fortunate in the universe, the most probability is also the most lonely existence.

But after encountering these civilization, you can represent the numbers in those values ​​will never be 0.

Two astronomers have boring, using a series of mathematical formulas and models, the value of each of the formulas.

Finally, the conclusions have been concluded that the number of planets in the Milky Way is approximately 11.117336, almost have eleven high civilized planets.

This number is quite accurate after we have encountered the Star League. "

"So the amount of civilization in the universe?" William is curiously asked.

"call…"

The slightly closed eyes of Hali's breath, slowly slow, opened his eyes again, lifted his left hand, start the five fingers:

"unlimited.

In our observable universe, there are more than 100 billion big stars, similar to the silver river is about 10 billion, and the quantity is about 100 billion.

Remember, this is still observable universe.

So I can say that there is an alien higher civilization in the universe, and it is unlimited. It can only be said that our Galaxy is relatively far and desolate. "

"Unlimited ..." After listening to the estimation of Harcy, William's hands holding the railings, and the forehead also seeps some cold sweat:

"That represents the number of three-level civilization, is it a lot?"

"This is not necessarily." Harcy said with a denial:

"The pioneer and ancient human beings are life created by superior civilizations such as pioneers, and quickly evolved into three-level civilization through the pioneer guidance.

The number of civilizations leaping on the three levels of the stars and galaxies can be described as a small number of, although it is placed on the universe, but it is very rare relative to the universe.

I firmly believe that our Galaxy is a special case. "
