Extragalactic cosmic ray Extragalactic cosmic ray Extragalactic cosmic rays are very-high-energy particles that flow into the Solar System from beyond the Milky Way galaxy. The energies these particles possess are in excess of 10 eV. Unlike solar or galactic cosmic rays, little is known about the origins of extragalactic cosmic rays. This is largely due to a lack of statistics: only about 1 extragalactic cosmic ray particle per square meter per year reaches the Earth's surface (see figure). There are many ideas about which processes may be responsible for cosmic rays with such high energies. In the 'bottom-up' approach, cosmic rays gain more
Beyond Entropy Architecture. The specific research of Beyond Entropy refers explicitly to some of the production of Arte Povera and Land Art. The prototypes in Venice were instrumental to reconfigure an architectural language articulated in five points: Since 2012, Beyond Entropy operates globally in situations of territorial crisis. Beyond Entropy has defined several regions of investigations: each region is analysed through a set of territorial problems that can be understood within the dialectics of energy and form, transformation and resistance, energy and entropy, matter and action. Beyond Entropy is currently working in the urban sprawl of some of the most industrialized parts
