光速与宇宙学
The Speed of Light and Puranic Cosmology
摘要：
我们调查了早期印度人关于光速和宇宙大小的想法。释迦牟尼（14世纪）说，速度是2，202 yojanas每半nimesha（每秒186，000英里！）。它显示了这种说法如何可能已经出现了从早期的Puranic概念关于宇宙的大小。虽然这个值只能被认为是一个惊人的巧合，但作为这一论断基础的《宇宙经》宇宙学阐明了许多古老的空间和时间观念。
英文摘要：
We survey early Indian ideas on the speed of light and the size of the universe. A context is provided for Sayana's statement (14th century)that the speed is 2,202 yojanas per half nimesha (186,000 miles per second!). It is shown how this statement may have emerged from early Puranic notions regarding the size of the universe. Although this value can only be considered to be an amazing coincidence, the Puranic cosmology at the basis of this assertion illuminates many ancient ideas of space and time.
