PRI at 50 Lightyears Out
January 24, 2012 12:14 PM Subscribe
Suppose an astronomer was sitting on a mirror of Earth less than 50 light years away and it was about 50 years in the future. On this mirror earth technology is similar to Earth's modern technology. What is the likelihood that their astronomers would have discovered Sol given its size and distance. How difficult would it be for a project the scale of the SETI array to listen to a 10K watt analog Earth radio station? Other details welcome.

For purposes of a detailed simulation. Could I hear a whole program such as, RadioLab, as broadcast from WNYC
from 50 lightyears away on parallel Earth using my massive radio telescope (assuming i found the signal and figured out how to hook it up to a speaker). Would it be especially static filled, or would I actually be able to make out the words from its hosts?
