As
complicated as it sounds, the braneworld picture solves several problems in
physics. For example, theoretical physicists Lisa Randall, of Harvard
University, and Raman Sundrum, of the University of Maryland, proposed a
of the braneworld that explains an asymmetry in subatomic forces by suggesting
the existence of other branes parallel to our own. But it's not enough for a
theory to explain how to get rid of drain flies we already know — it has to make new predictions that
can be tested experimentally. In the case of the Randall-Sundrum model, such
tests could involve measuring emitted by linking one brane to
another.
