>>> You are correct. This is very sloppy. First, I made a typo in
referring to the cube as 10^300 on a side when I intended to say 10^300
in volume. Also, the time area would be proportional to the other
spatial dimensions (a side) of the cube, not the volume. My apologies.
Again, the "time area" should equal a side if it is considered
equivalent to a spatial dimension.

the interference of all the information from all the alternative
outcomes. We gain the information of one possible outcome. From the
multiverse view, there is no gain or loss of information, but from our
perspective we gain one bit of information and the rest ends up in the
alternative outcomes.

>>> With regards to your last, time area expansion would accelerate
with with spatial acceleration. This means the number of stacks/outcomes
become more numerous. With spatial collapse the time-area would decrease
(stacks/outcomes decrease). (??)
