Query: Probing the Geometry of the Universe at the NLC   The hierarchy problem in particle physics has recently been approached from a
geometric point of view in different models. These approaches postulate the
existence of extra dimensions with various geometric properties, to explain how
the hierarchy between the apparent scale of gravity ${\bar M}_P \sim 10^{18}$
GeV and the weak scale $m_W \sim 100$ GeV can be generated. Generally, these
models predict that the effects of gravity mediated interactions become strong
at the weak scale. This fact makes the NLC a promising tool for testing such
extra dimensional models.
