    This paper is a brief (and hopelessly incomplete) non-standard introduction to the philosophy of space and time. It is an introduction because I plan to give an overview of what I consider some of the main questions about space and time: Is space a substance over and above matter? How many dimensions does it have? Is space-time fundamental or emergent? Does time have a direction? Does time even exist? Nonetheless, this introduction is not standard because I conclude the discussion by (...)

    Frank Arntzenius presents a series of radical new ideas about the structure of space and time. Space, Time, and Stuff is an attempt to show that physics is geometry: that the fundamental structure of the physical world is purely geometrical structure. Along the way, he examines some non-standard views about the structure of spacetime and its inhabitants, including the idea that space and time are pointless, the idea that quantum mechanics is a completely local theory, the idea that antiparticles are (...)

    In my 2013 article, “A New Theory of Free Will”, I argued that several serious hypotheses in philosophy and modern physics jointly entail that our reality is structurally identical to a peer-to-peer (P2P) networked computer simulation. The present paper outlines how quantum phenomena emerge naturally from the computational structure of a P2P simulation. §1 explains the P2P Hypothesis. §2 then sketches how the structure of any P2P simulation realizes quantum superposition and wave-function collapse (§2.1.), quantum indeterminacy (§2.2.), wave-particle duality (§2.3.), (...)

    In this article it is presented the idea that quantum electrodynamics has to be seen as a theoretical upgrade of classical electrodynamics and the theory of relativity, that permits an extension of classical theory in the description of phenomena, that while being clearly related to the conceptual framework of the classical theory – the description of matter, radiation, and their interaction – cannot be properly addressed from the classical theory. In this way quantum electrodynamics would not be a fundamental theory, (...)

    Extension is probably the most general natural property. Is it a fundamental property? Leibniz claimed the answer was no, and that the structureless intuition of extension concealed more fundamental properties and relations. This paper follows Leibniz's program through Herbart and Riemann to Grassmann and uses Grassmann's algebra of points to build up levels of extensions algebraically. Finally, the connection between extension and measurement is considered.

    The strings of physics’ string theory are the binary digits of 1 and 0 used in computers and electronics. The digits are constantly switching between their representations of the “on” and “off” states. This switching is usually referred to as a flow or current. Currents in the two 2-dimensional programs called Mobius loops are connected into a four-dimensional figure-8 Klein bottle by the infinitely-long irrational and transcendental numbers. Such an infinite connection translates - via bosons being ultimately composed of 1’s (...)

    This paper proposes a critical synthesis about different theories of time in physics and a new interpretation of its operational reality. We built it on two, deeply analyzed, fundamental ideas: the mathematical nature of Newtonian and relativistic time and the consequent need to build physical theories of time starting from the measurements obtained by real clocks. We observe that relativistic theories refer to axiomatic assumptions about clocks, probably not verified by experiments if we use clocks of different construction. We propose (...)

    Starting from a critical analysis of the clock effect, this paper proposes to deduce different operational definitions of time from the different clocks that we can use to quantify durations. A new interpretation of thermodynamic time, as different from absolute and relativistic, is introduced. The analysis leads to infer the coexistence in physics of different incommensurable operational definitions of time and the need of discuss their coherence and reality.

    In recent work, William Blattner claims that Heidegger is an empirical realist, but not a transcendental idealist. Blattner argues that, unlike Kant, Heidegger holds that thinking beyond human life warrants no judgment about nature's existence. This poses two problems. One is interpretive: Blattner misreads Kant's conception of the beyond-life as yielding the judgment that nature does not exist, for Kant shares Heidegger's view that such a judgment must lack sense. Another is programmatic: Blattner overstates the gap between Kant's and Heidegger's (...)

    In a famous quote reported by his biographer Marinus, Proclus says that a philosopher should be like a “priest of the whole world in common”. This essay examines what this universality of the philosopher’s religious practice entails, first with reference to Marinus’ testimony concerning Proclus’ own devotional life, and then with respect to the systematic Platonic understanding of divine ‘locality’. The result is, first, that the philosopher’s ‘universality’ is at once more humble than it sounds, and more far-reaching; and second, (...)

The objective of this paper is to show that the EPT agrees with the knowledge obtained from the successful predictions of Special Relativity (SR). For that matter, the new notion of a `categorical model of the EPT' is introduced: this is a category, whose objects (...)

Several examples of how life has been used to constraint space dimensionality (and vice-versa) are reviewed. In particular, the influences of three-dimensionality in the solar system stability and the origin of life on Earth are discussed. New constraints on space dimensionality and on its invariance in very large spatial and temporal scales are also stressed.

Our concern is mostly methodological: above all, we argue that a number of philosophical puzzles that arise in this field—puzzles concerning the nature of spatial entities, their material and mereological constitution, their relationship with the space that they occupy—stem from a confusion between semantic issues and true metaphysical concerns.

    In the course of the history of science, some concepts have forged theoretical foundations, constituting paradigms that hold sway for substantial periods of time. Research on the history of explanations of the action of one body on another is a testament to the periodic revival of one theory in particular, namely, the theory of ether. Even after the foundation of modern Physics, the notion of ether has directly and indirectly withstood the test of time. Through a spontaneous physics philosophical analysis, (...)

Quantum blobs are in a bijective correspondence with the squeezed coherent states from standard quantum mechanics, of which they are a phase space picture. This allows us to propose a substitute for phase space in quantum mechanics. We study the relationship between quantum blobs with a certain class of level sets defined by (...)

The aim of this chapter is to offer one such interpretation, the traces of which may be found already in Heisenberg's letters to Pauli from 1926, and in Dirac's anticipation of Heisenberg's uncertainty relations from 1927, that stems form the hypothesis of finite (...)

    Time travel is one of mankind's most ancient dreams. It inspires our imagination and provides material for bizarre stories. H. G. Wells' novel, "The Time Machine" (1895), marks the beginning of a long history of science fiction literature devoted to the subject of time travel. -/- A work on the subject of time travel forces us to re-examine our concept of "time". The complexity and the contradictory nature this subject makes it difficult to be more precise about "time". On its (...)

    Das Problem einer einheitlichen Grundlage alles Bestehenden hat seit jeher eine große Rolle in der Philosophie gespielt und stets auch eine große Ausstrahlung auf die Naturwissenschaft gehabt. Exemplarisch werden verschiedene Entwürfe für eine höherdimensionale einheitliche Feldtheorie diskutiert. -/- Es wird der Frage nachgegangen, was überhaupt unter der „Einheit von Theorien“ zu verstehen ist. Dabei zeigt sich, dass sich zwischen unterschiedlichen Ebenen der „Einheit von Theorien“ unterscheiden lässt. Die „Einheit von Theorien“ kann sich beziehen auf übergreifende Begriffe (z. B. Feldbegriff), auf (...)

    A true Turing machine (TM) requires an infinitely long paper tape. Thus a TM can be housed in the infinite world of Newtonian spacetime (the spacetime of common sense), but not necessarily in our world, because our world-at least according to our best spacetime theory, general relativity-may be finite. All the same, one can argue for the "existence" of a TM on the basis that there is no such housing problem in some other relativistic worlds that are similar ("close") to (...)
