In younger years I was an avid reader of anything my local library held in relation to astronomy/cosmology and would even travel to other libraries throughout Glasgow in search of a book I hadn't read yet.
Sometimes after reading and when, in a moment of quiet contemplation, I thought deeply about the vastness of space, it was freakin' scary if I went too far. Difficult to explain, as if a complete overload and my brain said, 'right, that's enough, we're shutting down' and had to seriously fight hard to get my thoughts back to normality! It would take several minutes or so.
Anyway, we digress and possibly an existing thread for anything related?
