Dark energy. Dark matter. These strange and invisible substances sound mysterious and their unexpected appearance in the cosmic census is upending long-held notions about the nature of the Universe. The Universe is known to be expanding but everything indicated that gravity should slow this spread. Instead, the Universe is accelerating its expansion and something stronger than gravity-dark energy - is at work. Evalyn Gates transports us to the edge of science to explore the tool that unlocks the secrets of these little-understood cosmic constituents. Based on the theory of general relativity, gravitational lensing, or "Einstein's Telescope", is enabling discoveries that are taking us towards the next revolution in scientific thinking-one that may change our understanding of where the Universe came from and where it is going.
Evalyn Gates is the assistant director of the Kavli Institute for Cosmological Physics, a senior research associate at the University of Chicago, and the former astronomy director of the Adler Planetarium. Her writing has appeared in Physics Today and the Chicago Tribune.
记得儿时的一个夏天,我和一群小伙伴在院子里望着星空胡说八道,其中的一个小伙伴说出来了关于宇宙的一番奇谈怪论,这番言论之荒诞不经,可能会遭到大人们强烈地嘲笑,但是当他说出来之后,却得到了小伙伴们一致地追捧,他的想法是这样的:宇宙,其实就是一个人体。那些个星球...
評分很好的科普书,《新量子世界》的姊妹篇。文中详细阐述了引力透镜等概念和广义相对论的中心思想。堪称天文爱好者的礼物。用大量篇幅详细地教读者如何提取哈勃拍摄的照片的信息。看完全书后再看看哈勃的照片,会有一种内行看门道的感觉!
評分天文学之于我,是非常温暖的记忆。 我非常清楚地记得在1986年初,当时的我还是个读小学低年级的小孩子。那段时间的的电视和报纸都报道了哈雷彗星要回归地球这个天文奇观。当时我家居然有《天文爱好者》,那是厂区图书馆对职工用比较便宜的价格卖过期杂志,每季度3...
