Only if you didn’t want to be found. Which would mean you would only not want to be found, if you had been found before and your planet bombed into near extinction.
Otherwise, the only reason to send a message into deep space is to get a response. If you encrypted that you would be an idiot.
This isn’t an interesting theory at all, it’s a nonsensical load of crap. You wouldn’t encrypt messages.....unless you had to.
Plus, the only way alien messages would be bouncing off our satellites is if they are super high powered(all the nuclear reactors in the world) narrow band laser beams more advanced then anything we have. AND POINTED AT US. If there are alien radio signals out there, they are so dispersed by range that it wouldn’t matter or not.
There can only be 2 reasons we haven’t heard from intelligent life elsewhere.
1.) Space is way way way way way too big. It’s simply not possible to send a understandable message over dozens of light years, well I take that back, probably possible. But you would have to have a habitable planet within dozens of lightyears(there might be one, probably none). So you’re talking hundreds, thousands, millions of light years. Nope not gonna get that phone call.
or
2.) There aren’t any intelligent species.
Aliens WOULD NOT , encrypt their messages if they were trying to contact “EARTH” from light - years away. They just wouldn’t.
Isn't there an element of "natural" encryption here, though?
So far as the aliens are concerned, our signals are in a foreign language -- even if they are not encrypted. And vice versa...
we aren’t searching for messages intended for us. we’re trying to eavesdrop on normal communications... because anyone trying to find random civilizations would have to send signals in all directions in the hopes of finding someone.
this has always been my issue with SETI.
the amount of energy needed to send an interstellar message would be fairly significant in order to avoid dissipating over the vast distance. as such, in order to be efficient, anyone communicating like that would do so in a very tight beam. eavesdropping on such a beam would have a very low probability.
btw, snowden’s concept that the signal would be indistinguishable from background radiation doesn’t work as such energy is extremely weak and wouldn’t travel very far once it hit any kind of obstruction.
as such, encrypted or not, if we happened to be in line with the transmission... it’d be very powerful and would definitely stick out.
the trick is getting in line at the right moment
I just figured the Bible is true and aliens are not in the future reality of the human race because it would muddy what has been revealed by God: JUDGMENT.
Amd yet, mankind has been using encryption for millennia
Checked your bank statement online lately?
If any aliens (or Eddie's erstwhile colleagues) were listening in, they should have seen white noise between the IP headers.
Eddie's theory is that, once a civilization is advanced, it encrypts everything, so that eavesdroppers from afar, if they see anything at all, see only white noise, not signs of civilization.
We’ve been sending messages deep into space since Marconi’s first emission. However, the inverse square law causes our perpetual comms field to dilute and blend, like the ripples of a raindrop on the ocean, long before it gets to the first star.
This isn’t an interesting theory at all, it’s a nonsensical load of Neil deGrasse Tyson.
Fixed it for you.
Our oceans would not protect us in this situation. but what if the aliens were poisoned by greenhouse gases, CO2 in particular?
What would we do then?
And what if they fed exclusively on aborted fetuses?
Would we defund Planned Parenthood?
