There are arguably too many unknowns to do much more than speculate.
But let's say there's some other planet with comparable technology. At what distance could we detect its routine radio emissions?
- fernly 7y agoNo more than 1000LY, per this article: http://www.setileague.org/askdr/howfar.htm http://www.setileague.org/askdr/howfar.htm i.e. 1% the diameter of the Milky Way: https://www.universetoday.com/21998/the-diameter-of-the-milky-way/ https://www.universetoday.com/21998/the-diameter-of-the-milk...
