We all think of it. What would aliens look like? Are they going to be good or bad? But it seems our "first" encounter is getting closer than expected - that, or stars are getting crazy.
A lot of us alien enthusiasts are always glued to the news when strange "signals" are detected. While skeptics do tend to keep an open mind, they don't necessarily mean they're dismissing the notion.
One recent study was from E. F. Borra and E. Trottier from the Laval University in Canada. And while their study hasn't been peer-reviewed yet, it's getting a lot of interest.
The two used data from the Sloan Digital Sky Survey and analyzed 2.5-million stars. Maybe because they have nothing else to do.
But what's puzzling is that 234 stars are generating "strange" signals. While this is a small fraction of their colossal number, the signals have the "exact shape of an ETI signal."
Of course, this was from one of Borra's previous experiments. In order to prove that such a signal exists, they had to be predicted and then proven.
But the 234 stars aren't entirely "random." They're in the F2 to K1 spectral range, meaning they're similar to our own Sun. And while the Sun has a planet with our species, why can't another's?
The two concluded that there are five potential "causes" of the "signals." They can be instrumental and data reduction effects, the rotational transitions in molecules, rapid pulsations, the Fourier transform of spectral lines, and the ETI signal.
And they're leaning towards extra-terrestrial intelligence.
Point is, there are 234 stars of a million that are generating strange signals
. They're the same signals that, if predictions are right, a technological society
would use if they also use lasers to communicate.
And if aliens really are true, then the first signs of contact will be indeed pulsed light signals.
