Este artigo apresenta alguns temas de discussão actual na astrofísica…Nunca mais vou encarar a ciência económica como controversa ou irrealista. Um pequeno excerto do artigo do New York Times:
““In the end, inflation saves us from Boltzmann’s brain,” Dr. Albrecht said, while admitting that the calculations were contentious. Indeed, the “invasion of Boltzmann brains,” as Dr. Linde once referred to it, was just beginning.
In an interview Dr. Linde described these brains as a form of reincarnation. Over the course of eternity, he said, anything is possible. After some Big Bang in the far future, he said, “it’s possible that you yourself will re-emerge. Eventually you will appear with your table and your computer.”
But it’s more likely, he went on, that you will be reincarnated as an isolated brain, without the baggage of stars and galaxies. In terms of probability, he said, “It’s cheaper.””
Terminada a viagem celeste, Menzie Chinn analisa vários instrumentos de política fiscal, com especial enfase nos estabilizadores automáticos, no seguinte artigo.
