So your argument is that intelligent life is rare and too far dispersed for physical contact? So what of electromagnetic communication?
I am going to resurrect this thread. My necromancer abilities are decreasing so i need to practice.
Electromagnetic communication? To understand why we might not see ET communication signals, we need an understanding of how we actually do "electromagnetic communication".
Every different intelligent civilization will have a different method for sending electromagnetic signals to communicate. Think of it as different languages. Just like we do here on earth. There are a lot of methods to send a wireless communication. Every method is an electromagnetic wave, but this wave needs to be manipulated to hold the information. This is where the "fun" begins. On earth we have a wide range of methods. Any alien can pick up the "run away" signals (they cover a circle with 70 light years radius), but can they actually see they are made from another intelligent civilization? Who's to say we haven't already picked up someone else interstellar message, but due to noise and other factors, we can't see an intelligent pattern to that message.
I leave you with a half arsed response, and some images you might or might not understand.
Can you tell that the signal in green holds the exact same information as the signal in blue?
This is an easy and very human method of communication, but would an alien understand that this signal comes from another intelligent civilization? Now add about 50 years or quite a lot more (26,400 years to reach the center of the galaxy) of this message flying across space, picking up a lot of noise, and you probably couldn't pick up any intelligent pattern. Leaving another galactic radio noise.
Oh i just thought of something else. Nothing to do with EM waves but still for the Farmi paradox.
According to the paradox, half the world should not have existed. Think of it like this, Rome, one of the most early advanced civilizations had no idea of China ( i may be very wrong here) and China had not knowledge of Rome's existence. So according to the paradox, both of them existing and not being to communicate with each other is very very unlikely. And yet it happens on the same planet, who is smaller than electron compared to the entire universe. I probably do not really understand that paradox, so can you explain to me, once more?
