摘要

月球是我们的未来。这似乎是一个预计耗资超过1000亿美元的嵌合体,而且还在不断增加,但迄今为止,阿尔忒弥斯项目几乎没有什么成果。然而,它是我们梦寐以求的最大型望远镜的理想地点,其波长跨越分米射电,从光学到太赫兹FIR。正是这些未来的望远镜,将揭开第一批氢云、第一批恒星、第一批星系、第一批超大质量黑洞以及最近的宜居系外行星的基本奥秘。它还不止于此。我们的月球望远镜将带我们回到宇宙最初的几个月,甚至回到大爆炸后最可能发生暴胀的前10(^{-36}}\)秒。我们的月球望远镜将提供高分辨率的系外行星图像,这些系外行星是与地球相似的“双胞胎”,并提供无与伦比的尝试,以回答我们在宇宙中是否孤独的终极宇宙问题。在这里,我将阐述我对未来几十年月球天文学的看法。

The limits of cosmology

The Moon is our future. It may seem like a chimera with a projected cost in excess of 100 billion$, and counting, dispensed on ARTEMIS with little to show to date. However it is the ideal site for the largest telescopes that we can dream about, at wavelengths spanning decimetric radio through optical to terahertz FIR. And it is these future telescopes that will penetrate the fundamental mysteries of the first hydrogen clouds, the first stars, the first galaxies, the first supermassive black holes, and the nearest habitable exoplanets. Nor does it stop there. Our lunar telescopes will take us back to the first months of the Universe, and even back to the first 10\(^{-36}\) second after the Big Bang when inflation most likely occurred. Our lunar telescopes will provide high resolution images of exoplanets that are nearby Earth-like ’twins’ and provide an unrivalled attempt to answer the ultimate cosmic question of whether we are alone in the universe. Here I will set out my vision of the case for lunar astronomy over the next several decades.

期刊介绍: General Relativity and Gravitation is a journal devoted to all aspects of modern gravitational science, and published under the auspices of the International Society on General Relativity and Gravitation. It welcomes in particular original articles on the following topics of current research: Analytical general relativity, including its interface with geometrical analysis Numerical relativity Theoretical and observational cosmology Relativistic astrophysics Gravitational waves: data analysis, astrophysical sources and detector science Extensions of general relativity Supergravity Gravitational aspects of string theory and its extensions Quantum gravity: canonical approaches, in particular loop quantum gravity, and path integral approaches, in particular spin foams, Regge calculus and dynamical triangulations Quantum field theory in curved spacetime Non-commutative geometry and gravitation Experimental gravity, in particular tests of general relativity The journal publishes articles on all theoretical and experimental aspects of modern general relativity and gravitation, as well as book reviews and historical articles of special interest.
