Are We Alone In The Galaxy? Updated Drake Equation Suggests We Might Be

[Maxmars]

If our "presence" within the galaxy is that limited (a mere 200 light-year sphere) we can probably be certain that no other civilization with "similar technology" could ever find us, other than good fortune.  But that's just for any other theoretical civilization 'like us,' within that small portion of the galaxy.

But then, higher technologies will appear as magic to us... maybe someday we'll know more.

Perhaps distance is just 'an illusion' to higher technologies.
