To date, SETI (Search for ExtraTerrestrial Intelligence) has focused on ETs who 'phone home' using the radio part of the electromagnetic spectrum, and even a very small region within that.
But what if ET's phone doesn't use radio waves? Sure the xkcd comic, is funny, but maybe it points to a deep flaw in our attempts to contact, or hear from, an ETI?
When Giuseppe Cocconi and Philip Morrison suggested the possibility of interstellar communication via electromagnetic waves in a 1959 paper in Nature, only radio was feasible, as we then had the ability to detect only artificial radio signals, if produced by ETIs with 1959 human technology. Since then we've developed the ability to detect a laser signal, brighter than the Sun (if only for a nanosecond) if it came from a source several light-years away ... but lasers weren't invented then.
What might ET's equivalent of ants' pheromones be?

This is a letter from ET to Earth: Do You Wish That We Show UP?
Translated to English:
This long letter to humanity appeared with no apparent return address. It is being posted here and there. This is another Internet piece for which I cannot assess the validity. All I CAN say is that it sounds like a good idea, is coherent, and is written skillfully at a level of intelligence and maturity with I would associate with a serious, non-technical, matter-of-fact level of discourse. It is not ethnically loaded and the writer has a very good understanding of language and human psychology, though there are a few moments where the grammar is different than we are accustomed to and there are a couple of language errors.
Most importantly, it makes no reference to impossible constructs, faux-tech, nor any type of religious or New Age buzzwords. I am also sending it to you because it might be real.
"Whatever it was, I got it while on an Evening photoshoot of the city and Venus." - Sean McCormick
The Norway spiral comes to mind when TheWeatherSpace.com received photographs and even an amazing video of the event. An object swooped down from the sky and then returned in a brilliant display on Friday night across the Western Canada areas.
Three different photographers have given their photos to TheWeatherSpace.com in what looks like something out of a science fiction movie. We cannot see what would cause this one Earth. The Norway spiral was said to be caused by a missile launch in the Russian territory. But what is this?
BENA, Minn. - Bigfootalive and living in northern Minnesota? The co-founders of the Northern Minnesota Bigfoot Society say, "100 percent yes."
They said they have received more than 75 reports of sightings, captured images, and Bigfoot footprints in just three years. They're sharing their insight while sorting fact from fiction as they take KSAX on the hunt for Bigfoot.
"I'm a skeptic of Bigfoot because I've trapped this whole area and never, ever did we see any Bigfoot tracks or see Bigfoot anywhere," William Tucker of Bena said.
Long time trapper William Tucker is anything but a believer, but just miles away from Bena, mind boggling footprints were found.
Each track was a bit different, different pressures, different depths, eliminating the possibility of some sort of footprint stamp.
A list of 10 of the most famous UFO incidents in history and how the authorities explained them.
One of several documented cases of triangular craft seen and recorded over Belgium during the 1990s during one of the most famous UFO "flaps" of the last 30 years.
Some of the most notorious alien sighting have been explained away by
1. 1947 Roswell crash: UFO proponents claimed that the US military had captured a crashed alien aircraft. This well-publicised, controversial incident became a pop culture phenomenon.
Explanation: the US military maintained that it had recovered debris from an experimental high-altitude surveillance balloon belonging to a classified programme named "Mogul".
2. 1947 Kenneth Arnold case: the press coined the term "flying saucer" after this American businessman and pilot claimed he had seen nine objects flying in a chain near Mount Rainier, Washington. Arnold described them as saucers skipping across water.
Explanation: The US Air Force formally listed the case as a mirage.
