The Drake Equation

An estimate published in the Astrophysical Journal concludes that there may currently be dozens of radio-capable civilizations in the Milky Way, with 36 being the most likely number. The researchers consider this estimate, created using the so-called Drake equation, to be conservative.
The Drake Equation (first proposed in 1961) is our best and only tool for answering this age-old question, even if it relies on things that are still very speculative.
Our yellow sun, for example, is relatively unusual in a galaxy where red dwarf stars are the norm.
Our location in a spiral arm is also something very special, far enough away from the center of our galaxy. So that suns can be formed that are active long enough and the density of matter is high enough, as well as the stellar mass distribution and the main sequence lifetime of stars. Without the direct influence of a black hole and much more.
It is estimated that our galaxy reached its peak (in terms of star production) about ten billion years ago.
I think 1000 for Cakkavala works very well as an average in our galaxy. Cakkavala, with a mountain Sineru. However, this does not mean that the 36 civilizations that exist there are not capable of cultivating other planets. That means around 1000 worlds with a Mount Sineru and perhaps 10,000 newly conquered terraformed planets.

1000 billion stars sounds like a lot. But 7 billion people and no known Arahant or even 1000, also.

In summary, the same conditions must be present to achieve the same results, and the conditions are very specific to our Earth. Maybe a 1000 in 100 to 400 billion chances. That would be an asymmetrical ratio of 1 to 100 to 400 million. That’s okay.

But as I said, there is no point in studying the finer details of the universe. We want to end the creation of suffering.
