We examine the current status of the physical version of the Church-Turing Thesis (PhCT for
short) in view of latest developments in spacetime theory. This also amounts to investigating …

Looking at very recent developments in spacetime theory, we can wonder whether these
results exhibit features of hypercomputation that traditionally seemed impossible or absurd …

In this paper we present a proof of a mathematical version of the strong cosmic censor
conjecture attributed to Geroch–Horowitz and Penrose but formulated explicitly by Wald. The …

We presented an interlude that the results of computability in the framework of relativity
effect. We would main focus on the computational power of the relevant models. Also, if …

We discuss the impact of very recent developments of spacetime theory, black hole physics,
and cosmology to well established foundational issues of computability theory and logic …

In recent years, discussions of supertasks involved a particular class of physical models
known as Malament-Hogarth spacetimes. One might wonder–what is the role of physical …

Abstract The Church-Turing thesis is examined in historical context and a survey is made of
current claims to have surpassed its restrictions using quantum computing—thereby calling …
