镜子。“PT定理”。
我们在二维世界中找到了第一个镜子。
(142)
但是通过两个镜子的连续反射,图像的图像与初始物体相同:
(143)
三维情况也是一样的:
(144)
...我们说过四维结构类似于动态全息图。从某种意义上说,你、我都是动态全息图。我们是四维结构。我们在空间中(如果我没记错,肝脏在右边)和时间中都有方向。我们可以分辨“右边”、“左边”,从过去到未来,以及时间倒流的情况。
如果你遇到一个镜像对称的人类生物,测试很简单:看看他的肝脏在哪里。
...时间测试则更困难。但通常,如果你和一个时间倒置的人交谈,过一段时间后,你会注意到:
- 他知道你将要告诉他的所有内容。
- 他忽略你之前说的话。(如果他似乎知道一切,那他就是上帝,按定义而言)。假设一个动态全息图遇到另一个动态全息图。它可以通过普通的镜子看它,也可以通过时间镜子看它。

考虑月球绕地球的运动:
(145)
考虑这个系统的镜像:
(146)
然后反转时间:
(147)
月球的运动及其PT对称形式是相同的。
...从物理上讲:想象你可以拍摄这个现象的电影。你坐在远处,拍摄月球绕地球的运动。然后你复制这部电影。你使用两个投影仪。在第一个投影仪中,你以正确的方向播放电影。在第二个投影仪中,你翻转电影,反转画面的空间方向:
(148)
注意:这部电影对应于三维时空(x,y,t)。然后在将图像投射到屏幕上时,你反转第二组画面的时间顺序。

上帝是一只巨大的蜗牛,它的柄状眼睛各自连接着一半相互作用的大脑,具有相反的生物钟。

Mirrors. "PT-theorem".
We found our first mirror in 2d world.
(142)
But the image of an image, through a succession of two mirrors, is identical to the initial object :
(143)
Same thing in 3d :
(144)
...We said that 4d-structure were comparable to animated holograms. In a way, you, me, are animated holograms. We are 4d structures. We are oriented in space ( if I remember, the liver in on the right ) and in time. We can appreciate what is "right", what is "left", what goes from past to future, avec what goes backwards in time.
If you meet an enantiomorphic human creature, the test is simple : look were is his liver.
...The chronologic test is more difficult. But, normally, if you talk with an antichron man, after a while, you will remark that :
- He knows enerything you are going to tell him.
- He ignores your precedent sentences. ( If he seems to know everything, he's God, by definition ). Suppose an animated hologram meets another animated hologram. He can look at it through an ordinary looking glass. He can look at it through a time mirror .

Consider the movement of the Moon around Earth :
(145)
Consider the mirror-image of this system :
(146)
Then reverse the time :
(147)
The movement of the Moon and its PT-symmetrical are identical.
...Physically : Imagine you can take a movie of it. You seat at distance and film the movement of the Moon around the Earth. Then you make a copy of the film. You use two projectors. In the first you introduce the film with correct orientation. In the second, you turn the film, reverse the space orientation of the frames :
(148)
Notice : this movie corresponds to a 3d space-time ( x, y, t ).
Then, when projecting the images of a screen, you reverse the chronology of the second series of frames.
(149)
God is a giant snail whose pedunclar eyes are each connected of half interacting brains, with opposite biologic clocks.
