The Infinite Turn and Speculative Explanations in Cosmology

Abstract: 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?

“…Nevertheless, counterarguments, and serious ones, are still adduced: and not only from the point of view of common sense, but also in respect of the extrapolation method -after all we judge the Universe by observing it from one, maybe vanishingly small, part -and from the point of view of other cosmological theories, which explain the same observations differently (see for example [Kazyutinsky, 1993]). Other doubts and issues concerning the Universe integrity and form see in [Marra, 2017;Panov, 2017;Stasishina, 2017, Kragh, 2014Gil & Alfonseca, 2014;Tavakol & Gironi, 2017;Brandenberger & Peter, 2017;Zinkernagel, 2014;Karpouzos, 2015;Ellisabc, 2014;Ackerman, 2017].…”

“…Somewhat paradoxically, the conservative mainstream of philosophy of science continues in the present period (roughly from the turn of the century) whereby many scientists firmly rooted in special sciences strive to extend some of the standard methodological strictures of previous eras to achieve a variety of new goals. With a few exceptions (e.g., Draper, Draper, and Pust 2007 and Tavakol and Gironi 2017) somewhat outside the philosophical mainstream, these developments have not provoked what we might have expected in earlier epochs. By and large, such work is either ignored by philosophy of physics (the majority) or downplayed and severely criticized (the minority) on the basis of old precepts and views of how real science needs to, has to, or used to be done.…”

“…The number of such universes is usually assumed to be infinite, or at least extremely large 9 . In this context, Tavakol and Gironi [20] speak about the infinite turn in contemporary cosmology.…”

“…Therefore, if we use the multiverse idea to explain some puzzling data in cosmology, we are, in fact, using an "explanation by unexplained" strategy. To quote the same authors: "The aim of a cosmological explanation should be that of providing a deeper understanding of the Universe, but the Multiverse type scenario rather shifts the target of the explanatory task from the finite observed Universe to a postulated relative or real infinite 'Landscape"' ( [20] p. 793) 10 . This consequently opens up a new question about the explanatory power of the multiverse idea.…”
