Ask yourself a question concerning the unknown beyond our universe. If you wish, answer the question.

Question 2

How big is the universe? You calculated the radius of the Hubble Volume (the observable universe) in Procedure 3 . Is it possible to calculate the radius of the entire (everything that is) universe? Justify your answer. (Hint: Consider the expansion rate.)

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.

Dogs have been used in studies to detect various cancers in human subjects. They have been trained to sniff breath samples from humans that were collected by having them breathe into special tubes. These people included 55 lung cancer patients, 31 breast cancer patients, and 83 cancer-free patients. The dogs detected 54 of the 55 lung cancer patients as having cancer, detected 28 of the 31 breast cancer patients, and gave only three false-positive results (detecting cancer in people who didn't have it).
