You see that is the problem, we use digital encryption, randomizing signals over several frequencies, such as spread spectrum techniques does, do you think you can tap those signals without the right key and hope to even see one single frame of data or image?
Nope, you can't.
Isn't that what I just said :confused:

No, I mean that from the OP the scientists are not seeking to view them, they're are only looking to detect them, which is a big difference.
No, that's the problem. If a signal is properly encrypted then it just looks like noise. You
can't detect it. Or at least you can't tell it apart from the background of natural radio emissions.

I, for one, can't wait for the real live tentacle porn.

So that would mean Japanese are really alien, eh?
Y'know...bukakke...tentacle porn...*cough*

It would be weird if the first signals we detected and decoded were from some kind of alien facist dictatorship. I'm not sure if that would classify as ironic or not, but it would sure be weird. :eek: :eek:

I can see the sci-fi novel/TV series now: Humans discover Nazi aliens, proceed to bring cause of Freedom into new worlds by means of LASERS.

There is a SERIOUS LASER DEFICIENCY in that picture.

A broadcast can't be a perfect encrypted stream as a receiver then couldn't decrypt the stream if it started in the middle. The broadcast needs to be split into blocks of short length, each of which is encrypted seperately.
Also a transmission (even an encrypted one) would have a finite number of recognizable symbols even if the symbol order was completely random or undecodeable.

I don't see how this is news. It's been known for ages that a civilisation in a certain stage in development tends to spray out highly distinctive patterns of electromagnetic radiation as a by-product of communication, and scientists have often speculated that we could use this to spot the trace of an intelligent civilisation. We've had radiotelescopes capable of picking up this kind of EM radiation for ages. There's no way of knowing what wavelength it'll be when it gets to us, because a) We don't know what wavelength it was when it started and b) Everything gets slowly red-shifted anyway.
Seriously, as far as I can tell, the story here is "Active wavelength of new radiotelescope happens to coincide with TV wavelength".
