Ummm, not really. In fact I'm pretty sure I made no mention regarding  
anyone traveling around or not.

I was trying to suggest that there may be classes of Dyson spheres that  
are not detectable to us because the inhabitants are so technologically  
advanced they have discovered the technical means to recycle or translate  
what we would consider low grade- low utility emissions back into some  
form of useful energy.

Yes I know what I'm suggesting is scientific heresy, and I should be burnt  
on a thermodynamically correct bonfire.

But I'm just sayin, that we the human race, haven't been practicing  
science and engineering for very long even by human standards. Maybe the  
universe is full of highly advanced alien civilizations that have been  
refining their scientific understanding for millions of years and they  
know things that we currently do not.

That seems like a fair assumption to me, given that we have been after all  
discussing some of the universe's puzzles for which we have no really  
conclusive answers.

And if Eugen doesn't like my suggestion, well tough, I'm pretty sure what  
I'm suggesting is already on the 101 solutions to the Fermi paradox list  
already anyway, and there's nothing he can say to have it taken off.  Nah,  
Nah Nah Nah, Nah! ;-)
