Comments of Professor Giulio Giorello about Renzo Bergamo's painting.

Possibile worlds
An other universe that's consistent with the laws of physics is possible, changing, of course, the basic conditions. When we change, even slightly the basic conditions, the underlying physics is going to change as well and thus other universes, completely different from ours may occur. Within some of these, probably, clusters, stars, planets and maybe life may exist. There maybe someone similar to me saying the same things about a painter as good as Renzo Bergamo, but in many other universes this won't happen and there won't be stars and galaxies or they won't be fit for life; maybe the life of some universes will be short and they will end in a dramatic and sudden way. From a physicist's point of view, this huge pluralism is today a possibility, moreover, it has become the basic setting of the theory known as chaotic inflation, by great physicists such as Andrej Linde, Alexander Vilenkin and many others.
We are not talking, of course, about physics related to fusion and fission or solid-state physics. Rather this is hypothesis of the physical world that gives us a chance to answer questions such as "what was there before the Big Bang?" or "what was there before the beginning?". There was another universe from which we originated.

Painting for Renzo Bergamo
The thing that catches attention, or at least that's what happened to me when I first saw Renzo Bergamo's work, is the power of the representation, the ability to express complex situations with a few strokes, in a wonderful and simple synthesis; this seems to me the common ground of an artistic representation and one peculiar kind of scientific model.In this way Bergamo's mark is able to express those situations that we recognise in some "x rays" of atomic physics, or in some pictures of a more ancient status of the universe.This is a very strong element, able to link different fields with a great expressive skill; is the same kind of expressive skill we find in Leonardo Da Vinci, when he represents the curls of a woman and a water whirlpool with the same mark. In my opinion this mark belongs to a kind of art that's deeply related with reality and one of the most exciting aspects of Bergamo's art.

When I think about light, I think about energy and somehow about Creation. Einstein's E=mc2, that connects so well mass and energy, comes to my mind. I think of the western intellectual tradition that, before Einstein; according to it "Light is the origin of all things" as the Irish philosopher Johannes Scotus Eriugena or, as Robert Grosseteste stated "God creates the world by the light or light is the language of God in the creation of the world". I find all this in the lesson of contemporary physics.

Past Present Future
If I am not mistaken, Bergamo would say that Time is our continuous invention, according to physicists or at least to a certain physics it is a spatial dimension rather than a flowing extent; therefore Future and past are somewhere out there. This is the idea of time that we have inherited from Einstein's Relativity. General relativity is here interesting because this time-space structure has a peculiar and fascinating geometry. "Where do the curve lines go?" says Bergamo, and this makes me think of matter telling Einstein and Mickovski's time-space the way to curve. Vice versa the bending of space-time reveals the presence of matter. According to me this cosmological conception is the way to rethink the concept of time. This may seem to be an abstract practice, compared to the perception of time we have in our daily life, when the past seem to be hopelessly lost and the future is filled with chances because it has not yet fallen into the present.Our referring constantly to a physical universe is still important because the aesthetic and ethic dimension of our experience cannot abstract from a cosmological intuition; maybe every good art, just as every good philosophy is, first of all, cosmology.
