Now you have to define "exists." :-)
The text "exists" only because I look at it and the light from the ink and
paper stimulates the neurons in my brain into a different pattern. The
information represented by the text does not "exist" if there's nobody to
read it.

Sure, in some sense. The arrangement of the atoms of ink and paper have a
surprisingly large causal effect when they are (for example) a declaration
of war. I don't know that you can say the *information* exists independent
of the text, for example.

Entropy is order, not information.

From lots of stuff I've read, information can't actually disappear. Or, to
put it another way, the "information" measured by entropy is only
"information of interest".
Certainly if you take a dynamic but deterministic system, like perfect balls
bouncing around inside a perfect box, and you start with all the balls on
one side and none on the other, entropy will increase even tho there is no
state of the box you cannot deduce from looking at any two moments of state.
QM does have a concept of "information" as well, and it's a symmetry (i.e.,
it might change form but the total amount stays the same). Indeed, that
gives rise to one or the other of the conservation laws that everyone accepts.

My understanding is that spacetime (aka timespace ;-) doesn't actually
exist, and the lack of its existence is the difference between SR and GR. If
you reformulate special relativity in such a way that you don't have a
"background" coordinate system but only the interactions between what's
there, you get GR. (I may be misunderstanding this, tho.)

I think that it's more a question of definitions than facts. :-) We have
names for all sorts of things that don't exist in the way they're defined,
like "meaning".

I don't know about "pure" consciousness. It's pretty easy to understand what
self-awareness is, and hence get an idea of what consciousness is.

That's self-awareness, not consciousness.

Probably a question of terminology;
here these terms were considered as synonyms
(pure consciousness = self-awareness, nothing more, no structures)
as in one of the definitions of consciousness on the Web:
"an alert cognitive state in which you are aware of yourself and your
situation".

I think you can be conscious without being self-aware. I'm pretty sure that,
for example, chickens would be considered conscious, even tho they're
probably not self-aware.

Or, more specifically, we have mass/energy, and we have relationships
between bits of mass/energy. While those relationships exist, they're not
"made of" anything beyond what they're relating. We think of relationships
(like information, "force", etc) but they doesn't exist outside our own
conceptions of them. If there were no thinking beings, there would be no
text, even if the paper with the ink on it was unchanged.
Sound exists as a pattern of air molecules. But it's made out of air
molecules, just like the molecules are made out of atoms, and the atoms are
out of protons and electrons and such. If you beleve that sound is made out
of something other than air, then you believe that air is made out of
something other than atoms.

what happened to the sound under water? Is it made of "air molecules"
too?

Yes, it is convenient to think so, but on the other hand they probably are.

Yes, it exists and it's made up of atoms. The atoms can either be part of
ink on the paper, transistors in a computer, or neurons in an animal brain.
It's like saying "happyness" exists, it only exists conceptually, physically
it's just represented by atoms.

Cars exist, and they can be created and destroyed, so cars cannot be the
same thing as energy. I don't get your point.

> Energy and information, and they are not the same thing.
Cars also exist, and they are not the same as energy or information, so we
have at least three different things. I'm not convinced by your logic
here...

Time must exist, or else it would be impossible to postulate essential
properties of physics such as the second law of thermodynamics. (In fact,
the concept of a closed system "going forward in time" is completely
equivalent to its entropy increasing; the two things are tied together.
You can unambiguously distinguish if a closed system is going forward in
time by measuring its entropy.)
Space must exist, or else it would be impossible to postulate essential
properties of physics, such as the Pauli exclusion principle. (How could
you state that two particles cannot be at the same *place* at the same
time if the very concept of "place" wouldn't exist?)
Just because space and time are relative doesn't mean they don't exist.

You can measure the entropy of text or a car, and you can compare it to
the entropy of something else. You could even ostensibly define a unit
of measurement for this.
If something is observable and measurable, and the properties of that
something can be well-defined, then that something is rather obviously
real, in other words, it exists. If it exists, the it's part of this
universe, in other words, it's one component of the universe.
If it exists and it can be created and destroyed, that makes it distinct
from energy, which cannot be created nor destroyed.

On what do you base the claim that they are not information?
