Subject: 6EQUJ5 aka Wow! Signal.

(NO TL;DR, THIS COMPILATION OF THE WOW SIGNAL IS GOING TO BE LONG, BUT INFORMATIVE)

Two different values for its frequency have been given: 1420.356 MHz (J. D. Kraus) and 1420.4556 MHz (J. R. Ehman). The frequency 1420 MHz is significant for SETI searchers because, it is reasoned, hydrogen is the most common element in the universe, and hydrogen resonates at about 1420 MHz, so extraterrestrials might use that frequency to transmit a strong signal.[1] The frequency of the Wow! signal matches very closely with the hydrogen line, which is at 1420.40575177 MHz. The two different values given for the frequency of the Wow! signal (1420.356 MHz and 1420.4556 MHz) are the same distance apart from the hydrogen line—the first being about 0.0498 MHz less than the hydrogen line, and the second about 0.0498 MHz more.
The bandwidth of the signal is less than 10 kHz (each column on the printout corresponds to a 10 kHz-wide channel; the signal is only present in one column).
Determining a precise location in the sky was complicated by the Big Ear telescope's use of two feed horns to search for signals, each pointing to a slightly different direction in the sky following Earth's rotation; the Wow! signal was detected in one of the horns but not in the other, and the data was processed in such a way that it is impossible to determine which of the two horns the signal entered. There are, therefore, two possible right ascension values.


>Info on Big Ear

The Big Ear telescope was fixed and used the rotation of the Earth to scan the sky. At the speed of the Earth's rotation, and given the width of the Big Ear's observation "window", the Big Ear could observe any given point for just 72 seconds. A continuous extraterrestrial signal, therefore, would be expected to register for exactly 72 seconds, and the recorded intensity of that signal would show a gradual peaking for the first 36 seconds—until the signal reached the center of Big Ear's observation "window"— and then a gradual decrease.
The transmission wasn't necessarily 72 seconds. The Big Ear heard it during the full 72 second window it had. The transmission could have been longer.

What could have been broadcasted longer??

The telescope was fixed and it's view cone covered a distance of 72 seconds, given the speed of the earth's rotation. The signal could have gone for ~23.998 hours but the telescope only caught the first .002% of it's duration. It also could have lasted, say, 23 seconds, in which case the telescope saw 98.6% of it's duration. The point is that the telescope could only see anything for 72 seconds.

t's an attempt at universal reasoning. If you're sending a signal, you have to chose a frequency, which is a choice with a ton of options. You could chose something at random, but then you have to hope whoever you are talking to is listening at 46kHz or 133.33MHz or 35.651GHz or whatever, and that's asking a lot. You can send the same signal over a bunch of frequencies, but that will cost you either transit power or time. So instead, you try to make an educated guess - if we don't know anything about the sending race, and they don't know anything about us, what frequency are we both likely to think of? Turns out hydrogen is really damn common everywhere, highly significant in a lot of ways that are the same everywhere in the known universe, and has a resonate frequency we could use. It's out best guess for a universal, interstellar signalling frequency.

>CHECK POINT
Now we know that the transmission was actually longer than 72 seconds!

We are going to continue with a few words at the Stephen Hawking approach.

The most logical approach is Stephen Hawking's approach- stay as silent as possible and don't broadcast your existence to the universe until you at least have the technology to visit other stars on your own.
Think about it- if there's even one highly advanced life form in the galaxy that's hostile, then the entire galaxy is devoid of all life forms that broadcast their locations. That explains the Fermi paradox- why, even though there's so many stars in the galaxy that it should be dotted with life- we have yet to discover one single trace of intelligent life. Everyone else is either smart enough to shut up, or is doing what we're doing now and has already been destroyed by hostile civilizations. Who knows- maybe there's something headed our way and we don't know about it yet.
Some people think this type of thought process stems from what European civilizations have done to the less advanced, but it's perfectly logical that the prisoner's dilemma forces all civilizations to try to wipe out unknown life forms before they overtake each other. Even non-hostile aliens won't know whether we're hostile or friendly and they might not want to find out. They might be a Type III or Type IV civilization on the Kardashev scale and can take us out with one gamma ray burst.
Or, they might be just like us... in which case it might take hundreds or thousands of years to rely simple messages and we won't be able to meet for generations. It'll be faster to search for the answers to our questions ourselves than to ask them. We have nothing to gain from any of this.

When we put our heads together and tried to list everything we could say with certainty about other civilizations, without having actually met them, all that we knew boiled down to three simple laws of alien behavior:
THEIR SURVIVAL WILL BE MORE IMPORTANT THAN OUR SURVIVAL.

If an alien species has to choose between them and us, they won't choose us. It is difficult to imagine a contrary case; species don't survive by being self-sacrificing.
WIMPS DON'T BECOME TOP DOGS.

No species makes it to the top by being passive. The species in charge of any given planet will be highly intelligent, alert, aggressive, and ruthless when necessary.
THEY WILL ASSUME THAT THE FIRST TWO LAWS APPLY TO US.
They won't come to get our resources or our knowledge or our women or even because they're just mean and want power over us. They'll come to destroy us to insure their survival, even if we're no apparent threat, because species death is just too much to risk, however remote the risk...

I believe there is life on other planets. But no green people with almond eyes living in flying houses on Mars.

vsauce says we should just be quiet so they don't know we're here

It's either radiation or life outside Earth.

ya but planets have formed before earth

it's possible there's life that has had billions of years to evolve and develop technology and we've only really been doing stuff for a few thousand years and look how far we've gotten
