Number of Alien Civilizations ( Extraterrestrial Life ) In Our Galaxy

Based on Earth’s experience, some scientists view intelligent life on other planets as possible and the replication of this event elsewhere is at least plausible. The drake equation calculates the number of advanced civilizations in our galaxy.

Extraterrestrial life is life originating outside of the Earth. It is the subject of astrobiology and its existence remains hypothetical, because there is no credible evidence of extraterrestrial life which has been generally accepted by the scientific community.

The Drake equation is a famous result in the speculative fields of exobiology and the search for extraterrestrial intelligence. It can be used to predicate (read as calculate) the number of advanced civilizations in our galaxy right now. But the result are not accurate and lots of criticism involved.

Disagreement (ie general ignorance) over these numbers leads to estimates of the number intelligent civilisations in our galaxy that range from 10^-5 to 10^6.
i. panspermia predicts 37964.97 advanced civilisations in our galaxy with a standard deviation of 20.

ii. the rare life hypothesis predicts 361.2 advanced civilisations with an SD of 2

iii. the tortoise and hare hypothesis predicts 31573.52 with an SD of 20.

And the number of intelligent civilisations in our galaxy is…

Have no fear

Recently I was reading very nice piece of information. According to Swami Vivekananda ”
The whole secret of existence is to have no fear. Never fear what will become of you. Depend on no one. The movement you reject all help you are free“.
All our problems and fears will come and go, just as we go, even god comes on this earth and go, and so have no fear. Always accept conditions, don’t expect & accept help form anyone.. this way we will not worry more about problems!
