Yes this is true as far as it goes but one of the things being discussed
by scientists these days is the issue of dark matter. Now it seems
we are getting closer to defining it, if you see the latest results,
dark matter has had its tempurature taken and it is called 'Tepid'
in cosmic terms, about 10,000 degrees C somewhat warmer than
the surface of the sun but a lot colder than its center. Now this is
of course only speculation but what I think he is talking about here
may be something like life appearing in dark matter. Dark matter
hardly interacts with what we think of as the normal universe, the
two types live independently. So it doesn't take a rocket scientist
to speculate about what that matter is capable of. For instance, if
such stuff can organize itself into more complex units of whatever
the heck it is, then maybe complexity can build on complexity in
that realm just like ours and lead to dark matter planets,
dark matter suns, dark matter beings. So if there were such beings,
as far as we are concerned, they would be as insubstantial as angels
and could be considered to be one and the same. This dark matter
stuff is all around us right now but we can't feel them with any
instrument, unlike neutrino's which we can't feel directly but know
them through our neutrino detectors which decade by decade get more
and more detailed information about just what makes neutrino's
tick. Neutrino's are far more interacting to what we consider ordinary
matter than dark matter ever will be. Neutrino's are thought to
cause some form of cancer and some mutations among life forms
here on earth. There will be no such thing happening with dark
energy, we run our fingers through the stuff like we run our fingers
through empty space (if we could do that). We only know about
dark matter because it has one tie to our kind of matter:
it produces gravity so it has some kind of mass, we just can't
detect it directly, only infer its properties by how galaxies
alter their paths under its influence. So there could be life forms
in that kind of stuff and we would not be able to detect it directly
unless there was some way that life form could make stuff like
light like laser beams or radio waves or gravity waves or even
neutrino message beams. So it is not an impossible thing to have
life that would not respond to our senses, even though it satisfies
all the criteria for life if we could but see it fully.
