纽约的美国自然历史博物馆门厅内矗立着新建的“宇宙雕像”,雕像的轮廓呈球面形,球心悬着一个象征银河系的S形铝片。
这是一件科学艺术作品。从科学的观点看,宇宙雕像代表了人类宇宙观的进步—从地心到日心,再到如这座雕像那样将银河系置于天球中心。与阿基米德和哥白尼时代相比,雕塑作者的宇宙观的确是大大的进步了,但问题在于这仍然具有局限性。现代宇宙学认为,宇宙中亿万个像银河系那样的星系的地位都是平等的,宇宙没有中心!以为银河系是我们所在的星系,便将之置于中心,这种观点与古代的地心说在哲学思想上一脉相承,比日心说反而退了一步
艺术观本来就是见仁见智,美感带有很大的主观性。依个人的浅见来看,宇宙雕像庞大的天球造型固然高大雄伟,但缺乏一种艺术魅力。当我们看到“维纳斯女神”雕像时的那种惊艳,非言语所能形容。罗丹的《沉思者》俯首沉思的形象使人产生哲学的联想,从而增加了视觉美的深度,欣赏这些经典杰作,会使人浑然忘我,情不自禁地进入美妙的艺术世界。宇宙至大无比包罗万象,按理更应该具有一种震慑人心的魅力。
宇宙雕像的巨大的金属圆环以及上面的许多连接小支柱使人联想起齿轮,它给人的整体印象是:宇宙是一部不断运行的巨大机器。牛顿时代的宇宙观确实就把宇宙看作一部硕大无比的巨型机器,发轫于此的牛顿力学,为工业革命及随后的机器文明奠定了理论基础,宇宙雕像表现了这种宇宙观。
现代天文学发现了天体的演化,演化过程中的威武雄壮瑰丽奇美,为艺术家们提供了取之不尽的灵感和素材。现代天文学已远远超越了牛顿时代的机械宇宙观,展现出奇幻迷离生气勃勃的演化的宇宙,艺术家有责任将之表现出来。
我国古代神话中,盘古在混沌中开天辟地,清者上浮为天,浊者下沉为地。这不仅与现代天文学里恒星从弥漫在天宇内的星云中诞生的思想不谋而合,且与大爆炸说中整个宇宙从一团炙热的原始物质内诞生有相似之处。我在想,能否以盘古开天辟地为主题与现代演化宇宙观相结合创造出一座具有东方哲理的宇宙雕像如能成功,这一定是艺术与科学的绝妙结合,至少不会使人产生对茫茫天宇的冷漠感和疏离感,因为盘古不是冷冰冰的机器。有心的艺术家们!想不想显一下身手

下列对“比日心说反而退了一步”所指的对象理解正确的一项是( )。

A.宇宙没有中心.

B.银河系是宇宙的中心

C.古代的地心说

D.牛顿时代的机械宇宙观
