Advances in technology have made great insights into habitable galaxies by now adding good figures to the Drake equation first two parameters concerning intelligent life in the Universe. Most scientists pooh pooh this equation and don't believe in extraterrestrials or other life forms in outer space. This could be one of the most backward propositions in the history of humankind.
The equation is completely statistical. One can estimate the parameters by experimental data, or by using the statistical methods which Maccone made. It is a good aspect to realise the extraterrestrial intelligent life and we are not alone in this galaxy. It is statistically consistent, but there is a lack of evidence which is known as Fermi paradox. Doing science always takes time. Encountering with any kind of extraterrestrial life also would take time.
It is obvious there are not many people out there in cyberspace able to handle this question as its gotten almost no interest at all! At least I tried!
Hi Tharaka Thanks for your reply re the Drake equation. Yes I believe there are beings in other dimensions. Science hasn't been able to cope at all with this high probability. We are still in the stone age because of blind thinking!
The elegance of this equation is including and discluding variables. Therefore, every single variable gives a different estimation for any desired case. That is completely statistical.
By analysing your example, if we consider "willingness" as a parameter, a civilisation either wills to contact or not. Hence, fwilling would be 0.5. If we would have any data for willing, would be different from 0.5. The number of technological civilisations in the Milky Way is N. Hence, the number of technological civilisations in the Milky Way which willing to contact would be 0.5*N.
N = R* fp ne fl fi fc L
fc is the technology parameter. If we disclude this parameter, the equation gives the number of planets in Milky Way which intelligent life has risen.
Different life forms are likely, but the probability is unexplored. Except, a life form in other dimensions is deeply speculative. "Dimension" is nothing further than a mathematical term. If one exerts "beings in other dimensions" as a multi-dimension sensitive organism— sensing more than three dimensions; this is similarly speculative. Moreover, considering the possibility of dark matter based life form is also speculative since the dark matter is not wholly solved.
I have taken the idea of dark matter based organism from the Netflix film Spectral (2016)— a science-fiction movie on the dark matter based synthetic soldiers.
Thank you Eftal. Ill work through this later and get back to you. Best regards.
Dear colleagues,
the question is: “Are we alone in the universe?”
I am geologist and palaeontologist, and based on my knowledge of the Earth history I come to the conclusion, that in the whole universe probably are only very planets with intelligent life. It is even possible, that our planet Earth is the only planet with intelligent life in the whole universe.
My detailed reasoning is given in following paper:
https://www.researchgate.net/publication/339644061_Milliarden_Jahre_Evolution_-_Geschenk_und_Auftrag_Billions_of_years_of_evolution_-_gift_and_mission
My considerations can be summarized as follows: The life on our planet is the result of 3.9 billion years of evolution. From the first primitive cell has evolved the abundance of life on Earth - including us, the human beings. In order for this first primitive cell to develop into the fullness and beauty of life and human civilization that we can observe today, the following circumstances and events, which can only be described as extremely extraordinary, were necessary, among others, in the course of the Earth's history:
1. About 4.53 billion years ago, a planet with approximately the size of Mars collided with the Earth.
2. The beginning and the strength of the release of oxygen by water-splitting photosynthesis was such that the Earth always had a temperature that was conducive to life.
3. The impact of a huge meteorite 66 million years ago caused the mass extinction at the end of the Cretaceous period.
4. Shortly after Homo sapiens had emigrated from Africa, was an interbreeding with Homo neanderthalensis.
Although there are an immense number of suns and planets in the universe, it is not likely that there are many planets with intelligent life. When we look at the series of events and circumstances that were necessary to bring forth what we now see on our blue planet, it is hard to imagine that many planets remain. The events are so extraordinary and the necessity that they had to happen at a certain time or at least in a certain period of time is so compelling that the probability of other intelligent life becomes very small. It is possible that planet Earth is the only planet in the whole universe that has produced intelligent life.

By the way, Sandberg et al. (2018) provide a condensed compilation of scientific data on the "Fermi Paradox". Although they take a different approach to their model calculations, they also conclude that there are probably no more civilizations of intelligent life in our galaxy, and possibly even in the entire observable universe.
