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!

Actually, isn't drake equation is just common sense. We could add more and more variables to that. For an instance, the willingness of the alien intelligence to contact us.

Furthermore, those intelligent creatures could be so different from us. They might be inhabiting the same space among us but we can not sense them. Like in a different dimension.

So I dont think this equation is useful.

Correct me if I m wrong.

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.
