Query: The infinite turn and speculative explanations in cosmology   Infinity, in various guises, has been invoked recently in order to `explain'
a number of important questions regarding observable phenomena in science, and
in particular in cosmology. Such explanations are by their nature speculative.
Here we introduce the notions of relative infinity, closure, and economy of
explanation and ask: to what extent explanations involving relative or real
constructed infinities can be treated as reasonable?
