太空灾难的政治

华盛顿特区 ——2010 年,世界各国得做一个颇为棘手的决定:是否支持俄罗斯联邦航天局( Roscosmos )局长阿纳托利·佩尔米诺夫( Anatoly Perminov )的提议,发射无人驾驶航天器,使一颗小行星偏出轨道,以免它在 2030 年之后撞击地球。

这颗小行星名叫“阿波菲斯”( Apophis ),直径 360 米,比一世纪前导致西伯利亚“通古斯大爆炸”的天体(可能是一颗陨石或 星)大 12 倍。据推测,该天体于 1908 6 30 日发生爆炸,能量相当于核弹,冲击波推到了方圆 2000 公里内的 8 千万棵树木。

据美国航天局( NASA )预测,如果阿波菲斯撞击地球,其释放出来的能量将比通古斯大爆炸强 10 万倍以上。爆炸将摧毁数千平方公里内的一切事物,扬起的尘埃将遮蔽太阳光并引发其他后果,使全球都受到影响。难怪俄罗斯研究人员给阿波菲斯起了个绰号,叫“来自太空的恐怖分子”。

    The Brexit Surrender

    European Union leaders meeting in Brussels have given the go-ahead to talks with Britain on post-Brexit trade relations.

  3. Murdoch's Last Stand?

    Rupert Murdoch’s sale of 21st Century Fox’s entertainment assets to Disney for $66 billion may mark the end of the media mogul’s career, which will long be remembered for its corrosive effect on democratic discourse on both sides of the Atlantic. 

    From enabling the rise of Donald Trump to hacking the telephone of a murdered British schoolgirl, Murdoch’s media empire has staked its success on stoking populist rage.

    The Dangerous Delusion of Price Stability

    Since the hyperinflation of the 1970s, which central banks were right to combat by whatever means necessary, maintaining positive but low inflation has become a monetary-policy obsession. But, because the world economy has changed dramatically since then, central bankers have started to miss the monetary-policy forest for the trees.

  5. Harvard’s Jeffrey Frankel Measures the GOP’s Tax Plan

    Jeffrey Frankel, a professor at Harvard University’s Kennedy School of Government and a former member of President Bill Clinton’s Council of Economic Advisers, outlines the five criteria he uses to judge the efficacy of tax reform efforts. And in his view, the US Republicans’ most recent offering fails miserably.

    The Holy Grail of Genetic Engineering

    CRISPR-Cas – a gene-editing technique that is far more precise and efficient than any that has come before it – is poised to change the world. But ensuring that those changes are positive – helping to fight tumors and mosquito-borne illnesses, for example – will require scientists to apply the utmost caution.
