I had a theory that it was someone walking across the field with an electronic device, like a flashlight. So I looked up the duration of the signal, size of the field, and average walking pace. It matched perfectly.

There's a story of a famous observatory that, iirc, kept on seeing really powerful intermittent signals that they couldn't quite hone in on. It seemed everytime they tried to zoom in on the source they couldn't find it again. Signal was quite elusive. They finally traced it to people using the microwave in the break room in a very specific way. Some people liked to open the microwave door before the timer went off. T…

Thanks... The fact that websites are now blocking Firefox by default as an "ad-blocker" is saddening.

For me it works just fine (with ublock origin enabled).

May be an a-b test?

If you read the article they actually refute it as extraterrestrial.

I'm not sure why you say that, the second abstract clearly says

> implying a galactic source ...

and

galactic source != aliens, astrophysical origin != aliens.

HN armchair astronomer question time. What's your favorite answer to the Fermi Paradox? Any crazy far-fetched sci-fi / pseudo-scientific ideas? I'm not really a fan of "Dark Forest". I prefer these: - We're truly rare, maybe even first. Intelligence is extremely hard. LUCA is old, civilization happened yesterday. - Fragile universe. It's easy to destroy universes by accidentally setting off vacuum collapse. This woul…

Mine is the Great Filter, basically a unification of life itself being rare and the universe being fragile. Though I don't think it reaches the level of destroying the universe, I think the filter happens at the level of being able to destroy a world or maybe a galaxy. I think evolution creates a local maxima that's incompatible with access to advanced technology (read: unbelievable quantities of energy). There's a b…

Mine is that fossil fuels exist on all planets that intelligent life evolves on, and all species extinct themselves once they discover how to use them.

Would you mind expanding on your theory more?

It was after watching a documentary called "WOW Signal". The receiver they built was along the edge of a field, and it's designed to pick up extremely weak variations in electrical signals/radio waves. They go into great detail about how sensitive it is. The signal itself looks like a parabola when graphed, gaining in intensity and then falling off at the same rate. Exactly what you'd expect from someone walking acro…

Also exactly what you'd expect if aliens were beaming a search signal into their sky, no?

galactic source != aliens, astrophysical origin != aliens.

extraterrestrial != aliens

extraterrestrial = not from earth

It would have to be a very specific kind of device. The "Wow!" signal isn't broad-spectrum noise. It's one specific frequency, and it just happens to be a frequency near one we expect to be used as a signal. Somebody could well have been walking across a field with a 1450 MHz generator. I don't know why; maybe it was a prototype of a portable microwave-oven/Walkman mashup. If so, it was leaky, and perhaps that's why…

> it just happens to be a frequency near one we expect to be used as a signal.

What's the reasoning for this? I've seen noted that the Wow signal of 1420 MHz is near the hydrogen line frequency, and is commonly detected astrophysically.

So is the reasoning just that, if you want to send a signal, then you might choose this frequency because other civilizations will probably have detectors tuned to it?

But then the flip-side of that is that if you detect this frequency, then it's almost certainly natural origin, from the excitation of hydrogen.

Yes, but one is far more likely.
