In theUniverse there are hundreds of billionsof stars. Many planets have already been discovered orbiting around stars in our galaxy. Considering this, there must be billionsof planets in the galaxies, which we observe. It is possiblethat there is developed life on some of them. If life on Earth is not just an accident in the planet’s evolution, then space must be filledwith life – diverse intelligent speciesand technologically advanced civilizations. However, we have not found such yet and it seems likethey are missing. This problem and many others find their answers in the modern sciencefor life and stars – astrobiology. I. Extraterrestrial beings and civilizations Possible life forms and life beings’ stage of evolution
The life forms may be small in size - bacteria and microorganisms - or they might be in a size similar to ours. They could have adapted for life on land - air, water, soil environment or in another organism. It is not necessary for life forms to be carbon- based as life is on Earth. They might be made of silicon. Depending on the environment of their planet, life forms may not have senses like we humans do.
Possible life form. Possible life forms and life beings’ stage of evolution
The planet experts examined life forms that might be present on celestial bodies like Mars and Titan (the largest moon of Saturn).
According to scientists organisms on Mars as an intracellular fluid can contain hydrogen peroxide, and the lives of creatures on Titan may be based exclusively on the chemistry of Possible life form. hydrocarbons.
The life of beings on Titan might be exclusively based on the chemistry of hydrocarbons.
Martian rabbit. Civilizations – stage of development
The level of development of a civilization may be considered depending on the amount of energy that it can control. This is the so called Kardashev scale. Extraterrestrial civilizations can be of three types compared to ours:
Possible communication between two forms of life. Civilizations – stage of development
I. Less developed than us
II. Developed as much as us
III. More developed than us (Kardashev scale)
Civilization type I -Technological level close to the level presently attained on earth, with energy consumption at 1016W
Civilization type II -A civilization capable of harnessing the energy radiated by its own star 4x1026W
Civilization type III -A civilization in possession of the energy of its own galaxy, with energy consumption at 4x1037W
A fictional civilization. Scientific projects about the search for alien civilizations
KEPLER MISSION Professor Sasselov suggests that the time needed for the creation of even the simplest form of life may be entirely commensurate with the age of the Universe. Therefore, if our brothers in mind exist somewhere in space it is more likely that their civilization would be less developed than ours.
In the past two years, search for planets around other stars outside our solar system, called exoplanets, led to the discovery of more than 2000 objects. With huge success the Dimitar Sasselov Kepler space mission was realized. Co-Investigator Kepler Space Missions The results of Kepler Space Missions The Fermi Paradox
We owe to Enrico Fermi the idea of his famous paradox, which asks:
"If we are not unique, then where are all the other extraterrestrial civilizations?"
Enrico Fermi The Drake equation
Humanity begins the search for extraterrestrial civilizations with a series of research projects.
Using this formula, he calculated Frank Drake how many civilizations, proficient in radio, there are in our galaxy the Milky Way. R* - the average rate of star formation in our Galaxy;
fp - the fraction of those stars that have planets; ne – the average number of planets that can potentially support life per star that has planets; fl – the fraction of planets that could support life that actually develop life at some point; fi –the fraction of planets with life that actually go on to develop intelligent life (civilizations); fc – the fraction of civilizations that develop a technology that releases detectable signs of their existence into -space;
fL – what part of time of the total existence of the planet will radio communication survive;
The results of the Drake equation can range from one to billions. Analysis of the reasons why there is no established contact with alien civilizations 1. The Earth is unique! 2. Every intelligent life form could face difficulties! 3. The aliens have left the Universe! 4. Earth is not as important as we think it is! 5. We live in a virtual reality! 6. We live in the depths of the Universe! 7. We haven’t detected their signals yet! Our place in the Universe. 8. We cannot recognize their signals! 9. Ultra-organisms are suicidal in nature! 10. They are among us!
We cannot recognize their signals. II. COMMUNICATION Forms of communication on Earth between different organisms
On Earth there are four main types of communication. The Linguistic communication (through a common language), expressions on the face, body language (some kind of dance) and written communication. There are also other types of communication.
There are two main types of communication between animals and humans:
I. Verbal communication II. Non-verbal communication Verbal communication
Verbal communication is when we speak. It is a system of phonetic signs.
Verbal communication has the following properties:
-the content -comprehensibility - the expressiveness Non-verbal communication
gestures – humans
sound – dolphins, whales, horses
light – sea mantis, fireflies
touch – elephant chemical way of communication – ants
image – aliens Forms of communication regarding the variation of alien beings
Communication with aliens could be established by using some of the known forms of communication. They may have senses to perceive anything.
Let’s take a look at some possibilities:
Possible life near a red dwarf star. Forms of communication regarding the variation of alien beings
The highly-developed creatures are a few types (considering their senses): ones with only hearing, with only sight and sight and hearing. We’ve discovered a planet on which there is highly-developed life. However, the planet is covered with water – one huge ocean. Keeping in mind the diversity of species in Earth’s oceans and their ways of communication between one another, we will take a look at the following possibilities:
The highly-developed creatures are two types: the first I. We suggest the following methodology regarding the first type (hearing) communicate with sounds and the (Communication via sounds) others use colors. II. For the second type (sight) we suggest (Communication via colors) III. For the third type (sight and hearing) we suggest (We use their better developed sense as primary and the other one as secondary) Analyzing possible ways of communication
Alien being: - presence of sight and specific facial growths – most probably sensitive
Home planet: - a huge ocean - aqua civilization - big in size considering the body
Communication: - via colors - images - careful and controlled touch Analysing possible ways of communication
Alien being: It has sight, perhaps also hearing because of the dense air
Home planet: Hot deserted planet, a dense atmosphere similar to Earth’s
Communication: - comprehensible sentences - via images and their - corresponding sounds Analyzing possible ways of communication
Alien being: Presence of sight and sensitive growths
Home planet: A dry deserted planet, low gravity, atmosphere similar to Earth’s
Communication: Communication via colors, careful and controlled touch Analyzing possible ways of communication
Alien being: Slow and steady non- aggressive actions, showcase of images in order to see how intelligent and curious they are.
Home planet: A rocky planet, low gravity, scarce vegetation, dense atmosphere, perhaps large consistency of O2 in the atmosphere.
Communication: Pick up vibrations easily, makes sounds. It can hold and work with objects (perhaps it lives in the tower behind). Analyzing possible ways of communication
Alien being: - present sight - makes sounds - specific growths
Home planet: - planet similar to earth - lots of sunlight - developed vegetation
Communication: Communication via colors, images and sound. Analyzing possible ways of communication
Alien being: Presence of well-developed sight and hearing, specific facial growths, sensitiveness, sound, change in temperature, close to Earth’s species.
Home planet: - a dark humid planet - a dense atmosphere similar to earth’s - diverse vegetation Communication: Possible contact by using the language of mathematics, via images, drawings and sounds. Analyzing possible ways of communication
Alien being: Presence of sight and specific facial growths which are most probably sensitive.
Home planet: - earth-like planet - vegetation - dense atmosphere
Communication: Communication via colors, images, careful and controlled touch. Analyzing possible ways of communication
Alien being: An Earth-like animal species, sound and non-verbal ways of communication.
Home planet: planet with a half-desert terrain; low gravity; vegetation ; somewhat earth- like; probably lots of O2 in the atmosphere
Communication: Slow and steady non- aggressive actions, showcase of images in order to see if how intelligent and curious they are. Analyzing possible ways of communication
Alien being: - developed hearing - uses echolocation - sight
Home planet: - a rocky planet with low gravity - dense atmosphere - earth-like vegetation, probably lots of O2 in its atmosphere
Communication: We will show typical sounds from Earth. Analyzing possible ways of communication
Alien being: Sight is present, probably even hearing, sensitive body. No information about intellect.
Home planet: - an aqua planet with a dense atmosphere
Communication: Contact via sound messages. Analyzing possible ways of communication Alien being: Presence of sight and specific body growths on its body, which are most probably sensitive, bioluminescence and echolocation.
Home planet: -a planet covered with one huge ocean - aqua civilization
Communication: Communication via sounds, images; we will showcase our planet with images . III. CONCLUSION
In the Universe there is a big diversity of planets orbiting around stars, each with its own unique characteristics. The specifics of exoplanets will determine the type and features of any possible extraterrestrial being. When taking into consideration every life form’s individual characteristics we will be able to come up with an appropriate way to mutually understand each other. People face a big challenge in discovering adequate ways to communicate with their cosmic brothers. This is the reason for why it is so important to successfully develop and examine different possibilities. Our project is a small contribution to this cause – it is an attempt to suggest our ideas for possible communication with extraterrestrials. We are certain that in time, along with evolution, humanity will think of ever better and more successful methods to socialize with representatives from foreign worlds. IV. LITERATURE
