Scientists Estimate At Least 36 Intelligent Alien Civilizations Exist In Milky Way Galaxy



There are many efforts going on in search of intelligent civilizations outside earth. It is one of the most preferred scientific riddles of our scientists. Recent research has given a unique opinion on this matter by adopting a different viewpoint. According to this study, there should be the presence of at least 36 intelligent civilizations in the universe at this time.

Estimation Of Civilizations In The Galaxy

It is very difficult to find out how much civilizations will be in our universe, and that intelligent civilizations. Recently published in the journal Astrophysics, research by the researchers of Nottingham University has been published in which they have adopted a different method. They used this preconception that if intelligent civilizations had developed on other planets too, it would have happened just like the Earth. Based on this, they calculated and estimated how much intelligent civilizations will be in our Milky Way Galaxy. According to their calculations, at least 36 active communicating intelligent civilizations should exist in our Galaxy.

Thoughts Of Evolution

While explaining his study on an astronomical scale, Professor Christopher Conselice of Astrophysics at Nottingham University said, "Our Galaxy itself should have at least a few dozen active civilizations if it were to assume that it takes 5 billion years for intelligent civilization to flourish on a planet. According to Conselice, this idea is based on evolution, but on the space scale, we call this calculation the Astrobiological Copernican Limit.

Calculation Of Data By Simplification

The co-author of this research, Tom Westby stated, "The classical method of estimating the number of intelligent civilizations depends on estimates of life-related values. But there are different views on this matter. Our study has simplified the concepts based on new data. This gave us a firm estimate of the number of civilizations in the Galaxy. "

How To Determine Numbers?

Westbay further stated, "Two Astrobiological Copernican limits are two forms of intelligent civilizations that came into existence like the Earth but either 5 billion years ago or 5 billion years later. Whereas many of the Sun's metals are present, we calculated that our own Galaxy should have about 36 active civilizations. " It is noteworthy that our sun is also rich in metals.

What Is The Role Of Technology?

The study pointed out that the number of civilizations depends more on how they send signals of their existence in the universe, such as satellite to the radio, television broadcasts, etc. If other technological civilizations lasted as long as our civilization It is about 100 years old, so according to this, there will be about 36 intelligent technological civilizations operating in our entire galaxy.

How Far Can These Civilizations Be?

The average distance between these civilizations should be around 17 thousand light-years, due to which it should be very difficult for our technology to catch their communication. It may also happen that now only we are left in our Galaxy, but this will happen when our civilization itself cannot last long.

Professor Conselice continued, "Our research suggests that the discovery of distant civilizations will not only give us an idea of ​​how life is made but also give an idea about how long our own civilization will last. If we can find out a civilization similar to ours, then we may exist for a long time, but if there is no active civilization in the Galaxy then it will be a bad sign for us. In a way, we are looking for our own future and results.

Oxford University Has Also Done Such Study

Human has been searching for aliens for years. Scientists have been trying to contact aliens by sending radio waves from the earth. This new study analyzes a mathematical basis of the Astrobiological  Copernican limit, In which the evolution of the universe was put on a scale. Earlier a similar study was done by Oxford University.

The Dirac equation was used in this. In this, a list of possible places was made, where life can exist. Professor Christopher says that the results of our study suggest that there are many more intelligent civilizations in the galaxy.

NASA Is Keeping An Eye On Other Planets With Hubble Telescope

Many countries of the world are trying out many new ways of exploring life in the Milky Way. NASA's Hubble Telescope is monitoring every planet's change that creates an imbalance in its environment.

China Created The Largest Single-aperture Telescope

China is searching for Alien Life by creating the world's largest single-aperture telescope. It is also studying other cosmological dimensions like telescope pulsar, black hole, gas cloud, and galaxy.

Astronomer Zhang Tongji of Beijing University says that we have received many signals from telescopes, which may indicate life in another world. The investigation is continuing.
