One of these days, if we don't destroy ourselves first, someone is going to create a sub-space receiver or some shiat and when they flip it on, they're going to pick up a shiat ton of alien transmissions.

Unfortunately it will be nothing but alien versions of morning zoos.

I'm gonna slaughter a Click 'n Clack joke but here goes:

Aliens give you a device that will allow you to contact them and provide workable solutions for all of the worlds problems including lasting peace.  Do you:
A:  Give it to the President of the United States (old joke/different president)
B:  Take it to the United Nations and demonstrate it before a council of the most learned (learn-ned) scientists on the planet?
C:  Take it apart to see how it worked?

Yup, aliens wouldnt be using radio waves. Surely theres some better way at doing long distance communications, like Star Treks subspace comms.

Interesting side note about that. In ST First Contact we see Earth developing subspace travel... which apparently is mankinds first experience with subspace phenomena. Its only later that mankind figures out how to use subspace for communication. I always thought this was backwards. Surely once you discover that subspace is a thing... communication through it is a simpler tech to develop & implement than actually travelling through it.

That's an odd thing to do with lasers.
 
2017-07-17 10:59:06 AM  
Radio waves are less directional than laser beams.  Also would think that the energy would be absorbed faster.

I don't want any undocumented aliens coming here.  We need to build a roof.

Why would you take it to the council of world dictators? Well, maybe it would give them workable solutions for better dictatorializing.

Just how diffuse would a laser be over dozens or hundreds of light years?

Why would anyone point a laser requiring about the entire energy consumption of the Earth at random stars for a second or two and expect to be answered?  Honestly, that makes about as much sense as the ant trail thing in the Boobies.

If it was done, it would also serve as its own warning system.  Get too close and we have a Zettawatt laser to defend our planet with!
 
2017-07-17 11:05:37 AM  
Actually the premise may in fact be correct, but we would need to 'aligned' with the target destination to pick up the laser signal.

How do you think data is sent from Mars?  We have a broadband laser data link to the planet, with receivers in Arizona and Australia.

Yeah.  Anyone good at math here that can calculate the probability of capturing a laser signal on a detector that small from multi-lightyear distances?

I'm thinking it's near zero.

Earth was a nuclear wasteland by that point. The first thing people probably would want (especially the wealthy ones, who might have caused certain actions to start WW3) is tickets off that planet to a habitable one quick.

We used electricity for mechanical purposes before we used it for communications.

Did they mention that they're trying to detect a beam aimed at us? Maybe they're trying to catch reflections off interstellar clouds which a beam has hit.

Look for quantum entanglement signatures then the FTL traces will light up the sky!

Maybe the first method devised for it is so ridiculously crude/generates too much interference Tthat communication through it is impossible?

Given that the most likely candidates in our solar system for extraterrestrial life are water worlds (Enceladus, Triton, Europa), there's a good chance of that.

I'd think any advanced species would know better than to blast easily detectable unencrypted signals out into the ether. You don't want your nosy primate interstellar neighbors eavesdropping on your hot nude sexting with the Jiggletastic Nippleclusters of Wob.

2017-07-17 11:56:31 AM  
Alien's are most likely using telepathy to communicate instantaneously, so to eavesdrop in, it would only take some tin foil and metal hangers attached to your head.
 
2017-07-17 12:00:27 PM  
Well i just think it would make a cool story if we figured out some sort of quantum or subspace communication system & first time we turned it on, it was already full of alien chatter.

If you knew anything!!anything at all about the nature of the universe, you would have hid from it in fear.

Life, as we define it, hasn't existed long enough in this little backwater of a galaxy for us to have become intelligent enough to recognize real "life" elsewhere in the universe. We can only recognize those attributes that WE have defined as life - Those attributes that apply to US.

The earth, and especially the life forms that cling to its surface have only existed for the mere blink of an instant in time, not near long enough for us to get intelligent enough to recognize that our version of life is probably completely unrecognizable from what actually constitutes most actual intelligent life in existence.

We humans are like blind amoeba, feeling around randomly with our feelers on the off-chance we'll accidentally stumble upon another, different kind of amoeba and from that chance meeting, believe we'll have figured our our place in the universe.

Meanwhile, our (human's) impact on the universe is so infinitesimally inconsequential that it impacts nothing but us. The entire Milky Way galaxy could wink out of existence at 2:00pm this afternoon and the impact of that on the rest of the universe would be absolutely nil.

The radio and laser signals would only be for a very small period of time until they move to quantum entanglement communications for long range communications.

ds615: So you're saying we invented sonar before boats?


We invented speech long before we even knew that air was a thing.

We've had radar & radio & the like for 100+ years now & still havent figured out how to send any physical objects through it or fly around in it.

I see subspace as one of those extra dimensions that string & quantum theory keep telling us about. I think that if we ever found a way to interact with those dimensions, communicating through it would be a trivial matter as compared to actually opening a magic door to it & driving through.

But its all theoretical & sci-fi technobabble anyway, so who am i to judge?
