Hi,
The aliens are not out there viewing I Love Lucy or Bert Newton. I was quite relieved when I found that out.
Those signals were broadcast by omni antenna and quite true, propagate as a bubble, rather than a beam, from Earth. They however degrade and "smear" quite quickly, and would not be intelligible (well, maybe even at broadcast
) much beyond our Solar system.
Cheers
