A block universe does not allow for consciousness.
Indeed! How is it even possible for any part of the block to have
anything like "something that is it is like to be conscious of some
other portion of the block"?
The fact the we all possess consciousness, so we think,
means that our universe is not completely blocked,
although the deviations from "block" may be minor
and inconsequential regarding the Omega Point.
To be conscious is to, somehow, be external to that which one is.

In Liouville mechanics, states of incomplete
knowledge exhibit phenomena analogous to those exhibited
by pure quantum states. Among these are the existence
of a no-cloning theorem for such states [21, 23],
the impossibility of discriminating such states with certainty
[21, 24], the lack of exponential divergence of such
states (in the space of epistemic states) under chaotic
evolution , and, for correlated states, many of the
features of entanglement . On the other hand, states
of complete knowledge do not exhibit these phenomena.
This suggests that one would obtain a better analogy
with quantum theory if states of complete knowledge
were somehow impossible to achieve, that is, if somehow
maximal knowledge was always incomplete knowledge
[21, 22, 27]. This idea is borne out by the results
of this paper. In fact, the toy theory suggests that the
restriction on knowledge should take a particular form,
namely, that one’s knowledge be quantitatively equal to
one’s ignorance in a state of maximal knowledge.
It is important to bear in mind that one cannot derive
quantum theory from the toy theory, nor from any
simple modification thereof. The problem is that the
toy theory is a theory of incomplete knowledge about
local and noncontextual hidden variables, and it is well
known that quantum theory cannot be understood in this
way [28, 30, 31]. This prompts the obvious question: if
a quantum state is a state of knowledge, and it is not
knowledge of local and noncontextual hidden variables,
then what is it knowledge about? We do not at present
have a good answer to this question.
