The telescope, yes.  But the galaxies it looks at? I don't really 
think so. We could get into a philosophical niggle here about how the 
stuff on the website is *really* the photons which hit the Chandra 
receptors, yaddah yaddah; but that would be off the point, because 
the basic semantic point can be made by having a web page which just 
says, in English if you like, 'This web page is about Julius Caesar'.

Not sure, but I am sure that there are things we can refer to which 
are definitely not part of it under any definition.

Imaginary things, things that no longer exist, things which never 
existed as physical objects (times, dates, numbers), etc etc.  OK 
there can be border cases that we can argue about, but it is 
*obvious* that reference is a wider notion than making links across a 
network, even such a grand network as the WWW.
