Loljesse.
What is this topic for?
I still havnt figured it out yet...
I know what the thing under Dennises picture is xD
N = N* fp ne fl fi fc fL - but none here =
The Drake Equation was developed by Frank Drake in 1961 as a way to focus on the factors which determine how many intelligent, communicating civilizations there are in our galaxy. The Drake Equation is:
N = N* fp ne fl fi fc fL
The equation can really be looked at as a number of questions:
N* represents the number of stars in the Milky Way Galaxy
Question: How many stars are in the Milky Way Galaxy?
Answer: Current estimates are 100 billion.
fp is the fraction of stars that have planets around them
Question: What percentage of stars have planetary systems?
Answer: Current estimates range from 20% to 50%.
ne is the number of planets per star that are capable of sustaining life
Question: For each star that does have a planetary system, how many planets are capable of sustaining life?
Answer: Current estimates range from 1 to 5.
fl is the fraction of planets in ne where life evolves
Question: On what percentage of the planets that are capable of sustaining life does life actually evolve?
Answer: Current estimates range from 100% (where life can evolve it will) down to close to 0%.
fi is the fraction of fl where intelligent life evolves
Question: On the planets where life does evolve, what percentage evolves intelligent life?
Answer: Estimates range from 100% (intelligence is such a survival advantage that it will certainly evolve) down to near 0%.
fc is the fraction of fi that communicate
Question: What percentage of intelligent races have the means and the desire to communicate?
Answer: 10% to 20%
fL is fraction of the planet's life during which the communicating civilizations live
Question: For each civilization that does communicate, for what fraction of the planet's life does the civilization survive?
Answer: This is the toughest of the questions. If we take Earth as an example, the expected lifetime of our Sun and the Earth is roughly 10 billion years. So far we've been communicating with radio waves for less than 100 years. How long will our civilization survive? Will we destroy ourselves in a few years like some predict or will we overcome our problems and survive for millennia? If we were destroyed tomorrow the answer to this question would be 1/100,000,000th. If we survive for 10,000 years the answer will be 1/1,000,000th.
When all of these variables are multiplied together when come up with:
N, the number of communicating civilizations in the galaxy.
It is the formula for the possibility of intelligent life in the universe. However humanity has not yet proven itself to be intelligent as evidenced by the ramblings and idiocy on the internet. Hence the “none here” comment.
It's a pretty ridiculous formula imo, and is completely useless for any practical applications.
Hypocritical paradox. Owned.
There is nothing hypocritical or paradoxical in a self inclusive opinion of the state of humanity. I have no illusions of my level of intelligence and know that not everything is about me, unlike others.
Your comment makes no sense Dennis. You cannot base the "possibility of intelligent life in the universe" on the behaviour of people on this forum. The "none here" can ONLY pertain to the ENTIRE UNIVERSE, by definition of your formula.
Hence making your thought pattern rather "nietszeggend", as we say over here.
Also, intelligence can go together with "internet rambling", some people can completely seperate the two "worlds" from each other.
Then you should probably make it more clear that it's just your opinion. Otherwise, it just makes you look more stupid than you claim to be. This is only a problem because the only reason I could see somebody making such a blasphemy of an avatar would be somebody who has a degree of ego based personalty earned through hard work.

Only because you wish to argue.

you misconstrue and misinterpreted in an attempt to create an argument without merit or else your English skills are not up to understanding the context . It is clear from my post that I feel that humanity as a whole is not intelligent and should not be included in the Drake equation as one of the possible intelligent, communicating civilizations in the universe that the equation postulates. Your assumption that I solely base my opinion on the ramblings of internet postings is either another attempt to argue with everything I say or a truly non-contextual mind set unable to conceptualize beyond the obvious but in either case it irrelevant to my opinion of humanity. Feel free to hold a differing opinion of humanity.

I would have thought it was obvious that it was indeed an opinion, as most generalities about humanity as a whole tend to be. I apologize if I shook your world view and led you to believe that it was a cold hard fact.

But as if other civilisations on other planets would make the same technology as us, they could be on hoverboards by now with virtual paper-thin computers or still building castles. And as if they would invent the same technology as us, its not like we broadcast the invention of a new gadget across the whole universe - example
"We made an iPad!........" Earth
"Picking up signal, unscrambling, activating super firewall, taking a donut break, resuming work, checking message, sighing because the other planet is technologically un-advanced compare to them, and finally activating halo and commiting suicide...." Other planet...
Okay too far... Off subject, correction, 2nd subject...
And yes we will kill ourselves, in alot of ways. Here are a few examples of what my grandkids are gonna probably die from...
Radiation from all the bloomin' waves from everything
CO2 poisoning
skin cancer from no ozone
laziness from when cars become useless due to no oil... (yes they will die unfit)
drowning from ocean rising
boiling in ocean if it warms too much
having no trees and dying from CO2 (again)
and anything else anyone wants to contribute to.
Thats right, say what you think humans are gonna die from in 30-150 years...
Seriously though, gimme the donut!!!
