"dimension" is usual term here. "Axis" is an element of a plot to show
the Cartesian coordinate system.

Hypervolume. And a n-1 dimensional manifold within an n-dimensional
space is called a "hypersurface". If linear, then "hyperplane".

The time dimension is not symmetrical to spatial dimensions. An
appreciation of Minkowskian space-time will tell you why. Try Wikipedia.

Wait a minute. In a cubic volume 10^100 plank units across, you've
assumed a discrete space-time, with n-states per cell. This gives rise
to 10^300 log n / log 2 possible bits of information in that
volume. How do you get to 10^200?

You lost me on the last point, above.
