This would be my message to ET

I'm sure various people involved in science and humanities discuss what message and information to send into space. I've looked at some of the sent and proposed messages, and frankly I think they're trying to hard. Unless you understand the context of the message, it's not going to have much more relevancy than mud soup. And throw in noise and other stuff, and the soup becomes muddier still.

As for my message, it's a hell of a lot simpler. And for anyone that sees it, it will be obvious once they bother to really look at it. Because it will be inherently artificial (of a pattern that isn't normally known to occur naturally) and that it will display some inkling of knowledge in mathematical constructs. So what is my message? It would be nothing more than counting to 100 in base 2. That's right, counting to 100 and repeating in binary. If you can use adjacent frequency pulses as the numeric placeholders, it seems that it would be possible to put a lot of directed energy behind them without too heavy of an average power demand. Also it doesn't need to be too fancy since the signal is only 8-bit, since we only need to count to 100 for our purposes. As for the bitrate? What's the longest dwell time needed to drive the signal to peak power on the transmitter? (I'm not sure on this, but I suspect it's pretty quick.) So the signal is pretty efficient in comparison to a constant and modulated carrier signal. And because the pulses are synchronous and ordered in a binary count, their artificial nature should stick out to anyone who analyzes them like a sore thumb. As for why counting to 100? Base 10 mathematics has pretty much been the basis for our scientific understanding of mathematics, which strongly influnces the rest of our understanding of science. So what is 10 squared? Exactly...

Ok, that significance might not be the most obvious to another society. But it would be a starting point in regards to setting up the foundation for a return signal and possible communication. Any similar binary counter over a series of adjacent pulsed carrier frequencies should be obvious, regardless of the arbitrary timescale chosen.

Now imagine each place holder as being a carrier frequency, with each digit being that carrier turned on. And of course that frequency is determined by it's placeholder value in the sequence. That seems obvious enough. And binary counting produces a nice branching fractal if represented as a grid. Even using the normal 1's and 0's it's still got a nice pattern to it.



At first one will most likely see repeating signal sources represented by the lower placeholder on the right, and at first hand may dismiss them for natural cyclic signals like pulsars. But if a bit more patience is taken, and all frequencies from a given source are analyzed. Then you notice the syncronicity and repeat rates for each digit. And then binary counting really sticks out, especially if it repeats at some chosen value that isn't a base 2^x and breaks the pattern when restarting.

And here's another site that shows the pattern.

Added a pic of what to send, or what to look for. At least this is how I'd do it.
