sphere, exp(-(R0-R)/a).
The potential itself is static, i.e. is NOT of function of t. But the
potential seen by the particles are not static. It is a function of space,

发表梅晓春文章证明爱因斯坦奇异性黑洞不存在
福州原创物理研究所
美国《国际天文与天体物理学杂志》（International Journal of Astronomy and
Astrophysics）和《宇宙学杂志》( Journal of Cosmology ) 近日发表福州原创物理
研究所梅晓春先生两篇证明爱因斯坦奇异性黑洞不可能存在的文章。
这一组文章的发表意味着，目前宇宙学和天体物理学中流行的种种时髦怪诞理论行将退
出历史舞台。霍金在《时间简史》中宣扬的，宇宙诞生于时空奇点、黑洞内物质崩塌于
奇点，以及所谓的白洞、虫洞和时间机器等被证明都是神马浮云，爱因斯坦引力理论的
弯曲时空描述方式面临严峻的挑战。
梅晓春文章的要点如下：
1. 现有爱因斯坦广义相对论黑洞理论计算的边界条件有误。按照正确的计算方法，黑
洞内物质不可能向中心崩塌，黑洞中心点密度不可能无穷大。因此如果宇宙中存在黑洞
，也只能是牛顿黑洞，不可能是爱因斯坦奇异性黑洞，宇宙从密度无穷大的奇点中诞生
的论断也是不可能的... 阅读全帖 |

This sounds like a physics-inspired problem, so let's try a physicist's

1. define a 2-body interaction energy function E(r) -- to achieve the
desired 2-body distance pdf P(d), set $E(r)=-(\ln P(d))/\beta$. See 3 below.
2. define that there is no direct 3-body, 4-body etc. interaction. Hence the

发帖数: 2024 | 13 There are several ways to consider this problem. You can compute the
electromagnetic energy generated by the charges. Outside the sphere, the
electric field is Q/r^2, inside the sphere, the electric field is zero. So the
static electromagnetic energy is Q^2/(2R). When R increases, the
electromagnetic energy is lowered and so the difference in energy is radiated.
Another way to consider the system is that for radius equals infinity, that's
the lowest energy of the system and choose it as zero. Fo |

Then inflation happens and during the process, the space DELTA

据台湾东森新闻云4月20日报道，《镜报》称，NASA的国际太空站（ISS），17日在进行直播外太空拍摄的画面时，意外发现一个不明物体，它状似马蹄型，出现在地平面上。当画面镜头旋转从背面转向正面时，突然出现断讯的情况。
当时不少观看的太空迷发现画面突然断讯，怀疑事有蹊跷，直觉认为有阴谋，画面一定是刻意断讯的，否则怎么会这么刚好，就在关键画面要显示时就断讯。而且不少网友认为，美国过去就曾有过隐瞒外星人存在的纪录，而且已经很多次，过去也有同样画面被切断的案例。
事后NASA解释，画面会断讯是“意外”，有支持者解释，过去也有过好几次刚好拍到不明物体时，画面正好消失。但是这样的情况又发生，让人怀疑这是否有人在背后蓄意操控，刻意想要隐瞒事实的真相。

试求指出讨论这个问题所需考虑的一些重要因素。
一 “文明”的定义应自史料内部辨认
讲中国文明的起源，第一步的工作自然是说清楚什么是文明，什么是中国文明，
这样我们才能谈到它的起源问题。最近在这个问题上的争论，有一部分是集中在“文

明的起源》，《考古》1987年第5期。）。
给文明下定义至少有两条入手途径。第一条是先决定文明这个概念之下包括什么
