I don't know what "pure consciousness" is. Can you explain it to me?
And how is it distinct from energy and information?

Sure, everything that exists can be called a component of the universe, but
it doesn't automatically mean that there are existing certain components
that cannot be made from energy.

How about arrangements of energy? They can be created and destroyed, yet
are still just energy in the end.

There's an important difference to what I said and you claimed I said.
Birds are animals, but "bird" has a different meaning to "animal".
Cars could be considered "information", but a "car" is different to
"information".
Cars are made from atoms, but a car is most certainly different to an atom.
My point is that information is just specific patterns of energy. I know
"energy" and "information" have different meanings and refer to different
things, but that doesn't mean information must be made up of something other
than energy.

The second law is statistical.

No you can't, because time is reversible. Entropy is an artifact of measurement.
Take a deck of cards and shuffle it. How likely is the order of cards you
just shuffled? It's exactly the same as the likelihood that all the cards
are in the canonical order (ace to king, sorted by spade, heart, club,
diamond). Entropy is a measurement of how interesting to us a particular
arrangement of atoms is. The fact that you can't get work out of random
heat is simply saying that it's really, really unlikely for random heat to
suddenly all go one direction.
Note that QM has no arrow of time. Reactions going forward are identical
(altho inverted) to reactions going backwards.
Break a rack of pool balls. (I.e., start the game.) Suddenly, it's much less
ordered. But if you could measure exactly where everything is at the end and
how fast it was going before it stopped and exactly how much friction there
was and etc, you could reverse that. (Modulo QM uncertainty, of course.)

The Pauli exclusion principle is not part of GR. It's part of QM. :-)

It does in QM. That's the fundamental problem and tension preventing GR from
being unified with QM.
The *concept* of place exists. It's just a question of whether it's
something real or something that falls out of our math and "common sense".
> Just because space and time are relative doesn't mean they don't exist.
Maybe I'm misinterpreting stuff like this:
http://math.ucr.edu/home/baez/background.html
It seems to be saying that GR says that space and time exist because matter
and energy exist. You can't have space or time without energy to be
experiencing them, just like you can't have sound without air to carry it.

You're trolling, right?

It can be distinct from energy and yet still be made from energy, just like
sound isn't air but it's made from air.
I'll grant you that "information" in the sense of "patterns of combinations
of something else" does "exist". I'm not sure you can say something is "made
out of" information, or that "information" would exist without the substrate
carrying it.
And I'm still not convinced you can actually destroy information. At the
quantum level, time is reversible, which means that information at that
level does *not* get destroyed. From lots of things I've read, figuring out
how you can have black holes and QM.

No, they probably aren't. You can test such things, you know. Dolphins,
gorillas, a few others probably are, including some birds.
Chickens and fish probably aren't.

Not at all; the question is interesting and
I just don't get it why you limit it the the air?
We can easily make and hear sounds under water, can't we?

You are right, it would be difficult to eat them otherwise.

I'd like to, but the language is a very limiting tool for this purpose.
I think of pure consciousness as the very basic self-awareness,
nothing more. It is clearly a distinguishing feeling,
but normally we have it at a very low intensity,
only sometimes it could suddenly become very intense for a short time.
Some find that the easiest way to deal with it is to assume
that it is one of the fundamental feature of the universe in the first time.
>And how is it distinct from energy and information?
This is what I eager to know too. May be information
could be considered as a structured energy?
Or an ideal structure, that could be filled with energy?

Of course, in which case the sound is made out of water molecules.
I'm not limiting sound to only be in air. I'm making an analogy.
