I asked for him to give us another try. He said he didn't know how to respond, needed some time/space to think, and that we'd talk soon. MeFi poll: how many days would this mean to you? Explanation inside. [more inside]

Would an alien radio pick up a cacophony or a damp fizzle?

If an alien located on a planet 100 light years from here was to switch on a big, multi-frequency radio receiver, and record all the noises coming from outer space for the next hundred years, on all frequencies, how many soap operas, advertisements and new broadcasts would they pick up from Earth? Would a mass-market radio, similar to our Earthly equivalents, pick up anything? Over time, as the number of Earth transmissions increases exponentially, would the alien pick up a cacophony or a damp fizzle? [more inside]

The mimetic and narrative capacities of artefacts

I am interested in the mimetic and narrative capacities of artefacts, how cultural remnants transmit information through time and how meaning is translated once an artefact is re-appropriated or examined from a new perspective. I have several avenues of study at the moment (a list in extended explanation), but would like some more ideas. Areas of critical theory, linguistics, evolutionary psychology and poetics are all relevant. [more inside]

Factoring 'Time' into Astronomic Observations

AskMeFi Physics folk: How do astronomers account for the temporal distinctiveness of their galactic subjects in their calculations? I understand that observations of the red shift of quasars delinates a speed increase in the expansion of the universe - yet my brain explodes when I try to understand how the enormous expanse of time is factored into these models.
