Abstract: | It is found that the existence of spacetime foam leads to a situation in which the number of fundamental quantum bosonic fields
is a variable quantity. The general aspects of an exact theory that allows for a variable number of fields are discussed,
and the simplest observable effects generated by the foam are estimated. It is shown that in the absence of processes related
to variations in the topology of space, the concept of an effective field can be reintroduced and standard field theory can
be restored. However, in the complete theory the ground state is characterized by a nonvanishing particle number density.
From the effective-field standpoint, such particles are “dark.” It is assumed that they comprise dark matter of the universe.
The properties of this dark matter are discussed, and so is the possibility of measuring the quantum fluctuation in the field
potentials.
