El nuevo acelerador de partículas LHC ya es el más potente del mundo
La máquina europea supera en energía a la estadounidense Tevatron, que mantenía el récord hasta hoy
Los ingenieros y físicos del nuevo acelerador de partículas europeo LHC siguen trabajando a toda máquina para ponerlo a punto y esta madrugada, sólo diez días después de inyectar los primeros haces de partículas, han logrado acelerarlos hasta una energía de 1,8 teraelectronvoltios (TeV), que es el record mundial. El LHC se ha convertido así en el acelerador más potente que se ha construido nunca, superando al Tevatron de Fermilab (Chicago, EEUU) que tenía el récord hasta hoy con casi 1 TeV por haz. “Todavía estamos haciéndonos a la idea de los bien que está transcurriendo esta fase de puesta a punto del LHC”, ha dicho esta mañana Rolf Heuer, director del Laboratorio Europeo de Física de Partículas (CERN, junto a Ginebra, en cuyo túnel de casi 27 kilómetros de circunferencia está instalado en nuevo acelerador. “Es fantástico”, añade Heuer. “Sin embargo, seguimos haciendo todo paso a paso y todavía queda mucho antes de que podamos empezar los experimentos de física, en 2010. Yo guardo el champagne en hielo hasta entonces”.

Space, Research And Never Ending Questions
Science@ESA: Space, Research And Never Ending Questions.
With 2009 being the year of astronomy it is important to underline that Space activities and scientific research in general need curious people who are not afraid to keep asking difficult, awkward questions even if they appear crazy.
Space scientists increasingly spend time, and have much fun, explaining in simple terms the nature of their research, often difficult to understand.
This video provides a lively example of this in an interview with astrophysicist Dr. Anja Andersen. She evokes her natural curiosity, in her field own of research and in everyday life, and gives examples of the some times startling questions that space scientists and engineers have to ask themselves.
When men strive to push back the frontiers of knowledge, science and dreams often come together in an extraordinary journey of imagination.
The Universe we know and our immediate environment are in constant flux. Each new answer on their mechanism entails a flurry of new questions. Scientists are never content.
Dr. Anja Andersen is a Danish astrophysicist working in Heidelberg, Germany. She exemplifies the scientist who juggles with seemingly impossible questions much like a child plays with a toy. And an interview with her can feel like an encounter of the third kind.
Over the years, the European Space Agency has proved that space visions can be turned into reality, and justify investments that may seem expensive.
Harnessing international efforts, like ESA does, to understand the Universe is no easy task. The men and women who work on the front line can take many risks. But space research and exploration also have another, less immediately visible benefit.
Far removed from the old idea of a scientist in his ivory tower, throughout her conversation Anja Andersen inspires by intertwining the more difficult theories of her field of research with practical issues of everyday life and reflection about mans existence.
It is thought that our Sun will burn itself out in some five billion years, engulfing its environment – and us turning into a dwarf star. By then, will be have understood the Universe? Not at all sure, but scientists will certainly have had time to ask themselves even more questions.
