The transmission at start of trailer is eerie

It reminds me of some of these 'numbers stations' broadcasting on short-wave radio I've only just been hearing about recently. The little, broken-up voice in the background behind the message is chilling and the 'scare' factor SRS promised us may lie in subtle stuff like this as well as full-on alien creepiness. The thought that this may be transmitting across thousands if not millions of light years through space from the past or future is seriously f**d up and is very eerie. That's just an inspired speculation from me based on the time dilation ideas that Scott also touched upon back in the early stages of this film. I hope he carries these themes across to Prometheus, because I find THAT sort of thing scary and haunting in a very insidious way. Sounds like the voice is saying 'it's coming' or something and I'm sure it's the Shaw and Vickers characters in distress or warning people away. Any thoughts on this?
