Prevención ante todo

Un colega atrajo mi atención a un artículo que habla sobre las medidas que se pueden tomar ante la inminente catástrofe (a sólo 5000 millones de años) que sobrevendrá cuando nuestro sol se torne en una estrella gigante roja. El artículo lo encuentran aqui. El abstract lo pueden leer aca abajo.

In around 5 gigayears our Sun will grow to a Red Giant and will swallow Earth. The plan is subdivided into two parts: We propose to construct some kind of parasol to shadow Earth. The position of the parasol will be the (inner) Lagrange Point L1. If we want to survive also the time beyond the next 5 Gy, where Suns luminosity and radius increase hundred fold and oscillate until our Sun develops finally into a White Dwarf, we have to shift Earth into the Kuiper Belt (50 AU) by means of the swing-by technique During this journey of about some megayears or more Earth must be illuminated by an artificial light source. A ring of DD-fusion power stations outstretched on Moons orbit should produce the necessary 175 PW of visible light. In the Kuiper Belt Earth will be brought into an orbit of an artificial Sun, an ArtSun formed in the meantime by the fusion of gaseous Jupiter-like planets imported from other planetary systems in the neighborhood

Me etretienen mucho los múltiples niveles de optimismo que los autores reflejan, además de su espíritu samaritano hacia sus tataratataratatara...tataratataranietos.
