This is a set of a few works of Polish philosophers and physicists on philosophical difficulties of time and spacetime. with out proscribing the thematic scope of the papers, the problem conceming objectivity of time circulation runs as a uniting thread via so much of them. partially it really is mentioned directIy, and partially the authors specialise in subject matters that are of paramount significance for one's angle to that question. within the first six papers the authors take care of their themes opposed to the history of latest physics, its theories, its problems and mentioned conjectures. For the paper of S. Snihur that heritage is supplied by means of daily worId-outlook, and the writer discusses the matter of life and personality of the longer term within the mild of simple rules of cIassical common sense. The paper of A. P61tawski, concerning the perspectives of the exceptional polish thinker Roman Ingarden, enriches the thematic scope of the coIIection introducing into it a few questions from philosophical anthropology and ethics. JERZY GOLOSZ movement, house, TIME*. summary. The paper discusses the homes of spacetime we examine by means of examining the phenomenon of movement. Of distinct curiosity are the spacetime symmetries. the spacetime buildings and the ontological prestige of spacetime. those difficulties are thought of at the grounds of the c1assical theories of movement contained in Newtonian physics, specific and basic thought of relativity. the debate among an absolute and a relational notion of movement and its ontological implications also are analyzed.

Example text

Physicists often say that particles 'move' or 'travel' on worldlines just to mean that a partide's history forms a curve in spacetime. ) There are also particles with rest mass equal to zero (photons, gluons, neutrinos) whose worldlines are null curves. This fact explains the name 'light cone' - photons emitted radially from a pointlike lamp as a flash of light describe a null cone in spacetime. Experiment then states that only timelike and null curves can be worldlines for material bodies; spacelike curves are excluded.

And in quantum gravity the metric is a dynamical quantum object experiencing quantum fluctuations. Hence the length of the vector also fluctuates and the fluctuations may convert in a chaotic way a timelike vector into a spacelike one and vice versa. The very concept of classifying vectors (and curves) in timelike, spacelike and null ones makes sense only for a smooth metric field on the spacetime; in case of discontinuous chaotic fluctuations of the metric one cannot say that a curve has adefinite length.

Each of these hypersurfaces is spacelike, in the sense that every curve, which entirely lies on one of such hypersurfaces, is a spacelike curve. In other terms these hypersurfaces are made (woven) of spacelike lines; it is then plausible to regard them as physical 3-spaces. Since the time coordinate is constant for all points of a spacelike hypersurface, one may interpret such a surface as a set of simultaneous events. Choosing a coordinate system in a region of spacetime one chooses a particular splitting of spacetime (in that region) into time and space.
