So lets talk hypothetical; you want to send a message to someone in the past, future, another world, the next dimension, you know the usual people you would send a message to. How would you send it? You wouldn't want it to be misconstrued or misinterpreted, what language would you use? There is only one that cannot be misinterpreted, a mathematical language. Religion couldn't twist it into something it's not and politics couldn't hide it behind something else. As my wife would say, numbers don't lie, they can't.
The next question is who do you send it to? A government, no they would try to use it to thier own benifit. A religion, no they would try to turn it into a message from God. You send it to everyone and wait to see who is listing.
What message would you send? Too complicated and very few if any would decipher it . To blatant and the people you don't want to notice a message might see it(i.e. government military) .Your first message might only be like a blinking light , just to see who notices the message . Then wait to see who sends the message back in response . You may now understand why I started the blog in the first place. At some point you would then send a code key or a Rosetta stone .
We are now awaiting the Rosetta Stone and we are listening .
