What Are the Odds That Aliens Exist?
Aliens and their types, as well as visitors to our planet has been a matter of study for scientists and many other researchers for a number of years now. It has been a subject of interest for the movie-makers as well as the common public, and that is why from various corners of our planet frequent news of visit of aliens and their various proofs of presence come forward. It is doubtlessly a matter of challenge for the scientists involved in space research as well as those who study the civilization and presence of life on various planets.
All think of human being, as the most intelligent, technologically advanced species in the whole universe. But when you see things upside down, there are more than 400 billion stars in our own galaxy – Milky Way only, and there are more than two trillion galaxies in the whole universe. Now it may seem that life can be inevitable in some of these places.
The perception one may have that there is no other superpower for science than human beings. They have grown big in all manner, developed in all aspects. The world has gone much ahead of the past. The mediocrities that certain factors bring into the light has a strong thought about the expectations about life into a big dilemma.
In this huge universe, there is an almost exponential number of prospects for advanced lifeforms, but till date, it is the humans that the universe knows as a superpower and the most advanced technology savior. Frank Drake, a known scientist, was the first one who came up with the first equation to predict how many such technologically advanced empires are present in the great cosmos in the present time.
His prediction relied on the sequence of indefinite magnitudes, that could make an approximation and later arrive at how many such technologically progressive alien species are present in our galaxy and the universe visible and know to us at the moment. But the precision in technology has advanced quite ahead in the past 58 years.
So these magnitudes that were indefinite in the past are now quite definite to an incredible degree of precision. For beginners, the understanding of the extent and measure of the cosmos has been enhanced dramatically. This is only being possible with the state of the art space and ground laboratories, that jackets the complete scale of the wavelengths, and can determine, how many galaxies are present within it and how many beyond.
No one has a better indulgence of the reality of stars and how they work. This is when one can look out into the fascinating chasm of deep space. One can analyze what the number of stars in the galaxy is. Not only in the Milk way but also all other the entire cosmos dating back to the era of Big Bang.
The integer is quite huge. It is somewhere close to 1024. This big number signifies the probability the universe has ever had, over the past 13.8 billion years, the age of its existence. Certain things can overturn as well. The key ingredients of the very first start come augmented with the heavy elements and constituents that are necessary for life.
The elements for the periodic table namely carbon, oxygen, sulphur, silicon, copper, iron, phosphorous and many more are found even in the interplanetary medium and also at the molecular gas clouds. These elements are just indispensable for the normal life as all know it. They happen to be the key bodily element.
The meteors and asteroids in the solar system do not have these elements, but one can find many organic molecules like sugar, carbon rings, and amino acids. If the theory is to believe, there are close to 1022 earth like planets in the universe. There lies a deceptive meaning behind this too. Not only, there are only alike planets, but there is also a probability that life is existing there or can exist.
These planets might have the atmosphere as of the earth or there may many civilizations flourishing. There can be a lot of biospheres that may have earth like circumstances and researchers are close to quantifying these worlds in Milky Way galaxy and other galaxies present in the universe as well.
There are three big steps, to get a civilization like a human
- The first step is the phase of abiogenesis. This is where the rare constituents are connected with animate dealings essentially develop what you be familiar with as “life.”
- Life must sustain and embellishment for billions of ages on a world to grow multicellularity, difficulty, inconsistency, and, in conclusion, what you call “intelligence.”
- And to conclude, that intelligent life must then grow a nominal advancement, either in advance the ability to state its incidence to the Universe, to spread out outside its home and see the sights of the Universe, or to reach the stage where it can listen for other forms of smartness in the Cosmos.
If one even gets to reach there, how intermittent is a tool, or technology developed rocket ship launching type like that of the human beings? The creatures like reptiles, birds and many more could be well thought out to be intelligent by many metrics. These creatures have been in existence for more than hundred millions of years, on the contrary, human beings have been predicted to be in existence for less than even one million years.
But they have evolved to be the most technologically advanced in the last century. When you start identifying the cosmos, it truly gives a bright light of many probabilities. You know that life like a human being ascended once in this Universe, at least, so the prospect must be non-zero. But further than that?
The fact that other creatures as advanced as human beings, can also have an existence or they may be the new descendants shortly. The future generation is going to noteworthy, for the reason that they have an opportunity to interact with the new species.
