    the first audio radio broadcast of voice and music occurred on December 24, 1906

    And the strength of that signal would have been so weak that even at a distance of only 5ly (maybe less), background noise would drown it out completely.

    No one knows we are here.

    200 light years radius is for radio signals to reach someone. 100 years radius for possibly receiving a signal back

    So I have more bad news, the strength of our radio signals is not very strong either so by about 20ly, they fade into background noise so no one would be able to pick them up at all. (could be a lot less than 20ly too, possibly 5 ly depending on the signal)








  • Mark Carney in Canada. A rebranded Conservative

    Well to be fair, the liberals always were the center right corporate party, and Carney could better be called a fiscal conservative. But our conservatives have gone so far off the insane right-wing deep end that we were left with no choice in the last election. Carney actually proved that when he put forth a conservative budget and forced the ‘conservatives’ to vote against it, begging the question “so what are you then if you are not conservatives?”
