Answer to Question 1

Students with good imaginations may have questions or views about what lies
beyond our current limits of observation. Formulating and discussing such questions
may be fun, but it must be remembered that any speculations about these regions of
space are not backed up by any concrete data and must be treated as possibilities
only.

Answer to Question 2

Since space appears to be expanding and accelerating, the radius must be increasing.
Our present data places no limits on this expansion and since it is space itself that is
expanding, we cannot begin to calculate the location of an outer edge even if such an
edge does exist. Because of this we cannot determine how big the universe is so no
total radius can be calculated.
