Alien Civilization Calculator is one of the best tools that help to analyse the number of civilizations in our galaxy. It takes the help of either the Darke equation or the Astrobiological Copernican Limits method to find the answer. You have to select one model, provide required input details in the milky way assumptions and hit the calculate button to check the number of civilizations in the result section in a less amount of time.
Alien Civilization Calculator: Calculating the number of alien civilizations is very difficult. So take the help of the flexible and free calculator available here. Get the meaning of the drake equation, astrobiological copernican and the simple steps to compute the number of active extraterrestrial civilizations.
Check out the more useful information about the civilizations in the galaxy, and how many ETs are really there. You can compare two models and which is giving the highest number of alien civilizations count. Read on to know the complete details about the concept of an alien civilization.
The following are the simple steps to calculate the number of alien civilizations in a milky way using two methods drake equation and the astrobiological copernican principle.
Astrobiological Copernican Principle:
The famous astronomer's Tom Westby and Christopher J. Conselice have published a new research paper in the Astrophysical Journal saying that there might be at least 5 other civilizations sharing the Milky way. So, we use this Astrobiological Copernican Limits method to find the total number of advanced civilizations. It is the most recent method that was developed.
The Astrobiological Copernican Principle equation can be defined as N = N* * fL * fHZ * fM * (L/τ')
N is the number of intelligent and communicable civilizations in the galaxy
N* is the total number of stars in the galaxy
L is the average lifetime of an advanced, communicable civilization
fHZ is the percentage of stars that host a suitable planet for supporting life
fL is the percentage of stars that are at least 5 billion years old
fM is the percentage of stars for which there is a sufficient amount of mental resources allowing the formation of advanced biology and communicable civilization
τ' is the time in which life ould exist
It is one of the popular ways to calculate the number of active extraterrestrial civilizations in the galaxy. Its simple formula is the multiplication of all the parameters. It was developed by Frank Drake to get the number of detectable civilizations in our universe.
The simple formula of Drake equation is N = R* * fp * ne * fl * fs * ft * L
R* is the average rate of star formation in the space
ne is the average number of hospitable planets per star
fp is the percentage of stars that have at least one planet
fl is the percentage of planets where life actually emerges
fs is the percentage of planets where life evolves into intelligent beings
L is the lifetime civilizations remains detectable
ft is the percentage of planets with intelligent creatures capable of interstellar communication
With the help of results from the Drake equation or Astrological Copernical Limits, we can estimate the probability of an alien civilization at closer distances.
It uses the volume of the cylinder, maximum volume in the space to find the probability. Its formulas are along the lines:
P = Vsearch/Vmax
Vsearch s the search space volume
Vmax is the maximum volume
P is the probability of distance

It is divided into four categories. They are

1. What is the use of the Alien Civilization Calculator?
Alien Civilization Calculator makes use of the Drake equation or Astrobiological Copernican Limits model to compute the number of advanced civilizations. At first, you have to select the model and give the different input values to get an accurate answer.
2. What is the formula of the Astrobiological Copernican Limits method?
Astrobiological Copernican Limits equation is N = N* x fL x fHZ x fM x (L/τ'). The parameters are N is the number of civilizations in the galaxy, N* is the total number of stars in the galaxy, fL is the percentage of stars that are at least 5 billion years old, fHz is the percentage of stars which host a suitable planet for supporting life, L is the average lifetime of a civilization, and τ' is the average amount of time available life to develop on a planet.
3. What is the Drake equation?
The Drake equation is the probabilistic equation that is used to find the number of active civilizations in the Milky Way galaxy. The formula is N = R* * fp * ne * fl * fs * ft * L.
4. Were aliens on Earth?
Some people say that aliens visit the earth just like scientists reached the moon and mars to check the existence of humans there. The assumption to describe the existence of aliens is the construction of large or heavy work that is impossible for humans. Examples are Egyptian pyramids and large mysterious stone statues on Easter Island.
