That must be true. I am trying to record, speech to text, my tinkling piss in the toilet but so far only soak my pants with the piss. True story bros. I swear my piss is talking to me but it might be my new hearing aids farking with me.

That sounds like the least efficient method of communicating other than stuffing a note in a bottle and flinging it toward the other system.

Bootleg: That sounds like the least efficient method of communicating other than stuffing a note in a bottle and flinging it toward the other system.


yeah, who would ever think about communicating with blinking lights?

Isn't that basically fiber optics?

The conditions that would be needed for someone to pick up and decode any message make it next to impossible. Which way do you point your limited resources? Cloudy night?

Yeah, Hubble is above the clouds, but can see only a tiny percentage of the sky. Again, which way do you point it?

Radio makes more sense than visible light. Much broader spectrum, and a signal in a specific part of the bandwidth WILL stand out from the noise. Broadcast in AM, FM, VHF, UHF. Radio can pass through cosmic dust that would block visible light.

If the target isn't technologically capable of handling radio, they wouldn't be capable of sending any reply via light.

We've been broadcasting radio and TV signals for more than a century, and it's unlikely any of it has reached a planet with life, much less one capable of detecting the signals. It's not essential that the aliens understand the signals; the presence of the 3.58 MHz colorburst in the old NTSC broadcasts would demonstrate an intelligent source.

What are they using to signal with? Giant mirrors? Or did they build shutters over their star?

Something about Ovaltine, I couldn't make it out.

Seriously - was the light gray text on a white background some kind of metaphor for the difficulty of reading alien communications? Because I had to go full squint to read that mother.

Yeah, 'Twinkling' is caused by atmospheric effects, and those effects can be mostly countered by shining a laser up through the air. Stopped reading there.

One of the strongest signs of alien life is Przybylski's Star that has einsteinium in its spectral lines. This is something not thought to be possible without a lifeform doing it, partly because einsteinium has a half life of 472 days. In 1978, it was also discovered to pulsate photometrically with a period of 12.15 min. You want a signal of life? Start there.

Personally, I think a civilization sending out signals into the universe is as good an idea as Anne Frank starting a marching band in July 1944.

Speaking of fiber optics, why do they only use a binary signal? Like, couldn't they also use things like specific wavelengths, intensities, etc to also carry data?

Well sure if you contact that planet of Nazis from Star Trek or those aliens from Battlefield Earth who come and bring death and more scientology.
But what if we make contact with a race of hot, sex crazed females who's men all died out and now they are looking for snu-snu? Is that not worth the risk? Can we afford to not take that chance?
If having our planet conquered and enslaved is the price we might have to pay for hot green skinned alien babe sex, I'm willing to take that chance.

You can't help it.  Any technological species is going to signal its presence in one way or another once it hits a certain level of technology.

At least, that's according to Imperial College London quantum physicist Terry Rudolph, who last week published preprint research

Seriously. Stop with the farking preprints. Do you know what a preprint is? IT'S A FARKING BLOG POST.

Fiber optics do use different light frequencies on the same fiber for massive bandwidth https://en.wikipedia.org/wiki/Wavelen​g​th-division_multiplexing#Dense_WDM Satellite and microwave systems use frequency and phase.  It's all still ones and zeroes, though.

Ah, neat. Internetworking isn't my field, I just always thought it would make sense that you could use different intensities, wavelengths, etc. to transmit multiple signals on one pipe.

Doesn't change that it's as good an idea as Anne Frank starting a marching band in July 1944
