双语:科学家发现宇宙绝不止一个

除了地球,还有其他宇宙吗?除了地球,还有其他宇宙吗?

  Alternate or parallel universes may actually exist, according to the findings of one astrophysicist, but many in the scientific community aren't convinced.

  根据地理物理学家的发现,平行宇宙可能真的存在,但许多发现都没有在科学界获得认可。

  Ranga-Ram Chary, U.S. Planck Data Center's project manager in California, recently discovered a “mysterious glow” by mapping the Cosmic Microwave Background, otherwise known as the light that was left over from a few hundred thousand years after the Big Bang.

  最近,美国加州普朗克数据中心的经理Ranga-Ram Chary,在绘制宇宙微波配景辐射图时发现了一束“神秘亮光”,被以为是宇宙大爆炸几十万年后遗留的光芒。

  Ordinarily, Chary would have found nothing “except noise.” But the spots of light were 4,500 times brighter than they should have been.

  通常,Chary的发现除了噪音没有别的,但这一束光的亮度相比之前的高出4500多倍。

  Chary concluded that the glow could represent matter from another universe “leaking” or colliding into ours. This would validate the hypothesis that our universe is merely “a region within an eternally inflating super-region,” said Chary in an Astrophysical Journal study published in September.

  Chary以为这束光代表着另一个宇宙的物质“泄露”或是闯入到了咱们地点的宇宙,他在9月份发表《地理物理期刊》中称这一发现证实了之前的假设,即咱们地点的宇宙空间存在于一个“一直收缩的超级大空间”之中。

  Cosmologists have speculated about multiple universes for years, but have thus far been unable to prove their existence. Chary's research is therefore significant because it could lend credence to the theory that cosmic inflation — which is the notion that the universe began inflating right after the Big Bang — led to multiple universes.

  多年来宇宙学家一直在推测多重宇宙的存在,但至今都无奈证实。因此Chary的研究意义重大,因为其证实了宇宙收缩说,即宇宙在大爆炸之后开始一直收缩,最终导致多重宇宙的产生。

  However, this type of claim would “require a very high burden of proof,” Chary wrote. There's a 30 percent chance that the glow is nothing out of the ordinary.

  但是Chary还写道,这种论断“须要非常确凿的证据”,该光束是普通光芒的几率仍然有30%。

  Other scientists share this skepticism. Alexander Vilenkin, director of Tufts University's Institute of Cosmology, doesn't see how “this signal can be explained by a collision with another bubble universe.” Any collisions must have been “more like little nudges,” Vilenkin added. “But a collision that would greatly enhance the density of protons seems to require a much more violent encounter.”

  另外一些科学家对此持怀疑态度,塔夫斯大学宇宙学研究所主任Alexander Vilenkin以为,这束光芒“无奈说明为宇宙碰撞的线索”。他说:“任何碰撞都更像是微小的震动,但要使碰撞能够极大的增加质子密度,则须要更强烈的破坏力。”

  ”The supposed observations of a giant void and an apparently cold spot in the cosmic background radiation have so many types of potential explanations,” said Jay Pasachoff, chair of the astronomy department at Williams College. He maintains that it's too premature to cite an alternate universe as the explanation.

  威廉姆斯学院地理系主任Jay Pasachoff称:“在宇宙配景辐射中观察到的巨洞和类似的冰点都存在多种形式的说明。”他强调引用平行宇宙来说明这一发现还为时过早。

  ”But it could also be something new and unexpected,” Vilenkin added.

  Vilenkin最后说道:“但是,这束光芒也有可能是新的未知事物。”
