We should beam back our commercials at them... they may just change their mind and switch to ads-free alternative.
"Earth Peoples, we come for the secret of the ShamWow"
> For the most part, these detections were one-offs, flashing briefly before disappearing entirely. I realize there is most likely an explanation that doesn’t require intelligent alien life, but that screams Dark Forest Theory.
We should broadcast the coordinates of a distant star to see what happens.
Don't known much about astronomy, but day as a unit of time is just a constant specific to our particular solar system. I guess a function of the sizes of the sun and the planets here. There should be nothing special about it. To think that 500M light years away there is something that has similar time proportions to be observed here as periodic is amazing by itself.
If aliens did exist, they would probably compress their communications. And they might use a fault tolerant infrastructure like TCP/IP. In either scenario, real communications would not be periodic but closer to random noise. Has anyone performed a Zipf plot or calculated shannon entropy of non-periodic radio signals?
in the data stream, sure, but the underlying data framing would probably still have very strong patterns as compared to true noise

Until one day when it becomes true ..

As does encrypted data.
That’s why somebody needs to send out a sequence of prime numbers
Isn't it strange that the periods mentioned are integer multiples of days ? Don't known much about astronomy, but day as a unit of time is just a constant specific to our particular solar system.

So the period is neither an integer multiple of days, nor exactly the same each time. There's some small variance involved - about 1%.

Some of the earliest radio broadcasts are Hitler's speeches, as well as other world leaders preparing their nations for global conflict. So there's that.
Ironically in 1948 when FM was standardized and countries were assigned spectrums Germany wasn’t really invited as it wasn’t a state for that short period and wasn’t assigned a spectrum so they started broadcasting in VHF because that wasn’t covered by the Copenhagen Agreement.
A few years later people realized that VHF was supper efficient for FM unlike AM and (W)Germany ended up holding all the cards.
This is why (primarily older) VHF FM radio compatible receivers in Europe will have UKW FM or UKW option in the turner which stands for Ultrakurzwelle (Ultra short wave) that was before UHF was standardized above the VHF spectrum.
If it's periodic, it's something orbiting something. If it's powerful enough to be seen 500 million ly away, one of the two orbiting objects is going to be a black hole.
You can imagine other cyclical processes, but I don't know any are realistic.

Or one thing rotating. You can imagine other cyclical processes, but I don't know any are realistic.
