Saul Perlmutter, Brian Schmidt y Adam Riess han sido galardonados con el Premio Nobel de Física de este año, por descubrir que la expansión del universo se está acelerando (constataron que las estrellas más antiguas se expanden mucho más rápidamente que las nuevas). Este fenómeno no se ha podido explicar todavía, aunque hay dos principales interpretaciones; que se deba a la influencia de la energía oscura del universo, y la que más partidarios tiene, es la fuerza de repulsión (como la gravedad, pero de signo contrario) que define Einstein con su constante cosmológica.
Lo que parece claro, es que el destino del universo es acabar totalmente helado. Menos mal que faltan muchísimos años para eso. (Ilustración:Nasa)

This phenomenon has not been explained yet, although there are two main interpretations. One of them is due to the influence of dark energy in the universe, and wich has the most supporters, is the repulsive force (like gravity, but opposite sign) Einstein defined as the cosmological constant.
What seems clear is that the fate of the universe is a completely frozen end. Fortunately it will be in a very long time. (Illustration: NASA)
