Physically, a fireball is a small rock that originated from an asteroid or comet that typically leaves a fading smoke trail of gas and dust as it shoots through the Earth's atmosphere.

大奖,一直没有。

收入一直没有。但是,我知道,时间越少越少,

危机越来越多。

我必须开始全身心投入工作了。

必须完成我的使命和责任。

首先需要构思大概内容。书写出来。

在新网站上。

然后,每天写一些思想,充实内容。

数学逻辑学物理学,很多地方不明确,

但是,没法细致研究了,必须完成我的工作。

那就把想法写出来吧。

提纲,细节。未来伏笔。过去埋笔。

都要用文字体现出来。开始吧。阿们。
