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.
在天文学漫长的研究史上,人类每跨出一步,都会感受我们与宇宙的距离既在增近又在远离,这样的矛盾就好比宇宙的加速膨胀和引力作用的强烈存在一样。每当人类看到了更为广阔的宇宙面貌,同时又会发现许多新的未知。于是伴随着很多的设想,宇宙变得越发的不可穷尽。尽管如此,却...
评分很好的科普书,《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!
评分在没看到这本书时,我对暗物质和暗能量的概念一直模模糊糊。看完这本书后,更加迷糊乐。 这不是说这本书不好,恰恰相反,这是目前我见到的对天文宇宙领域最新领域描写得最好的科普。因为它没有避开我们宇宙学的最新结果,没有讨论虚幻的弦理论,而是实打实地告诉我,引...
评分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...
