The existence of extraterrestrials and the Drake equation

The idea of ​​extraterrestrial life is nothing new. Many philosophers have hypothesized the existence of life on other planets like Earth – with the idea that the way or cause of life on Earth could also happen on other planets. There are billions of galaxies or galaxies in the universe and scientists estimate that there are about 40 billion stars in these galaxies, including our sun. There are many stars like the sun in this vast universe.

Some of them may contain systems like our solar system, where life could exist. In addition, scientists and researchers have noted some features by observing the Earth’s geology and weather, which suggest that life can or has occurred in a planet. Many people talk about or see UFOs (UFO = Unidentified Flying Object) seen in different parts of the world at different times for proof of life outside the earth.

Astrobiologists, astrophysicists and NASA scientists claim that extraterrestrials visit Earth almost regularly and are seen regularly. So it is not impossible that animals exist elsewhere outside of Earth. There is a clear reference in the Holy Qur’an (Surah Ash-Shura, verse number-29) about the existence of human-like creatures elsewhere in the creation world – ‘One of His signs is the creation of the heavens and the earth and the living creatures He spread between them; He is able to assemble them whenever he wants.

Recently, using the European Southern Observatory’s Atacama Large Millimeter/Sub Millimeter Array (ALMA) telescope, researchers claimed to have been able to detect this fundamental element of life. Harvard-Smithsonian Center for Astrophysics researcher Karin Oberg reported their discovery.

Recently, the James Webb Space Telescope reported that NASA has found unequivocal evidence of life on an extrasolar planet 120 light-years away from Earth. There, scientists identified the molecule dimethyl sulfide (DMS), which is produced only by animals on Earth.

Meanwhile, a star called MWC 480, 455 light-years away from Earth, claims to have found compounds (molecules) like carbon and methyl cyanide in the dust cloud. Scientists have confirmed that many Earth-like planets have such complex molecules, which are the basic ingredients for the origin of life. NASA researchers using the Kepler telescope have discovered 20 planets that may have life on them. According to them, NASA is not far from aliens on different planets.

By 2025, NASA will reach aliens, which will be the biggest recent discovery on Earth. Astrobiologists estimate that our galaxy has about 500 habitable planets. American astrophysicist Frank Drake invented a mathematical model, known as the Drake equation, to determine the number of planets in these numerous galaxies.

The number of stars, the different environment and conditions of origin of life, the movement of intelligent beings and the process of development of civilization with advanced technology can be analyzed through this equation. The origin and development of life on Earth, the birth and death of stars, planetary evolutionary biology, history, politics and abnormal psychology have been considered to gain acceptance of the equation.

The whole matter is expressed in the form of the equation below. ध = जड्धा चड्धड उद्धा धड्धा द्धा द्धा. Here d = number of intelligent beings trying to communicate with humans from the world at the moment. H = Number of stars in the galaxy. f = Probability of finding a planet around a star. U = If there are such planets, the number of planets suitable for the development of life. B = If there is a planet suitable for development of life, there is a real possibility of development of life. O = If life really does develop, it is likely that it will develop intelligence such as communication with otherworldly creatures. J = the time up to which the intelligent creature can survive.

Most stars in the Milky Way galaxy have lifetimes of hundreds of billions of years or more, during which time they steadily emit radiation and provide energy for the origin and evolution of life on nearby planets. It appears that when a star is formed, some associated planets are born along with it. We know this from various sources, such as the presence of satellites of most of the planets of the solar system including Jupiter, Saturn, Uranus, binary stars and the observation of gaseous material revolving around stars.

This suggests that most stars have planets. At present about 3710 planets have been discovered in about 2780 planets. This happened in 20 years. Scientists have shown many proofs of the existence of life on these planets. For example- 1. Temperature – The first characteristic required for the origin or support of life on a planet is temperature.

Because the temperature determines the atmosphere of a planet. If the temperature of the planet is high, the atmosphere will be gaseous and hot. If the temperature of the planet is low then the atmosphere of that planet will be very hard and cold. 2. After water-temperature, the importance of water for life is immense. Even in the context of Earth, the first life arose in primitive aquatic environments. The requirement of water is directly or indirectly important for the survival of life. Note that the ice accumulated on the surface of Mars, which indicates the existence of water on that planet – that is, the existence of life there.

3. Sources of energy – After water, life needs sources of energy. Animals on Earth generally obtain energy in two ways. First, sunlight and second, oxidation-reduction chemistry. Either of these two energy sources must be present for life to exist on a planet. Outside of Earth, the high temperatures, large amounts of ice, and large amounts of gas in the stars and planets prove that life exists there. 4. Nitrogen and Oxygen – Where life exists, proteins or amino acids are bound to exist.

The essential element for amino acids is nitrogen. Nitrogen is therefore an important element for the chemical activity of life. About 78 percent of the Earth’s atmosphere is nitrogen. The presence of oxygen and nitrogen in planetary satellites is noticeable. That is, it is natural for life to exist there. 5. The vastness of the universe also provides evidence for the existence of life. Most of the stars in the Milky Way Galaxy have lifetimes of hundreds of billions of years or longer.

They radiate steadily over long periods of time and provide energy for the origin and evolution of life on nearby planets. Because the universe is so big, according to Stephen Hawking and Carl Sagan, the possibility of life beyond Earth is also high. So the question comes, why these animals are not communicating with the world? The answer is – since each solar system is located many light years away from each other (one light year = 946 thousand billion kilometers), it is difficult and almost impossible for us to find the existence of life there.
