‘This exhibition is of spatial dimension: space as an external space perceived by people (section I), but due to the very fact that it is perceived, it is inevitably internal space, space which is lived and imagined (section III) and moreover, scanned and built according to the precision of mathematical relationships. Ours is an Einstein universe, governed on a vast scale by the gravitation which Einstein explained as being space time curvature. How many dimensions are there in our universe? Are, there hidden dimensions? Are there universes in other dimensions? The exhibition certainly does not give an answer to these and other queries, as at the moment this is impossible, but it does attempt to guide the visitor. The exhibition is in 3 sections: 1st Section: “Cosmic Zoom” is a panorama of 42 kinds of spatial magnitude, or better still of distances. It goes from the 10-13 cm. of a proton’s diameter to the 10+28 cm. of the visible universe, in other words that which we know something about. In this first section, various groups of kinds of magnitude are documented, proceeding centimetre by centimetre from quarks (proton components) to quasars (the most distant objects in the universe). This first section has a synthetic, suggestive image in the form of a space model with multicoloured lights which as distances pass, rises and moves off from the observation point. 2nd Section: dedicated to the modern scientific conception of space resulting from the theory of relativity, it therefore attempts to give a notion of space/time curvature and its effects. By means of mirrors which distort the images and suitable geometric forms, visitors are able to experiment for themselves the deformation and the contraction of space, as well as the alteration of several physical laws, passing from one space to another. The construction of the famous “rubber plane”, which curves under the weight of bodies laid on it, simulating space/time curvature, is also scheduled. By means of this curved table, visitors can carry out experiments on the orbits of heavenly bodies and the deviation of light beams, verifying the effects according to the theory of relativity. This section is also equipped with models of the various possibilities of space curvature (rectilinear, open, closed) as well as models of spaces with several dimensions. 3rd Section: on the subject of man’s perception of space. The term “perception”, must not be confused with “sensation”, or “view”, as it indicates a complicated mental process situated half-way between sensorial and behaviour processes. Visitors will encounter classic images presented by perceptive psychology to make us more aware of our representative mechanisms. Alongside the psychological matter there is a series of reproductions of works by C.M. Escher and Victor Vasarely, two contemporary artists who are aware of the results of research on perception. The realization of the “Ulysses and Cyclopes” distortion chamber will provide visitors with an impressive example of what we see and what we expect to see.’
