Phe-nomenon

Universal wave function, 19 | Reductionism 4

Impartial/All is the Noumenon, which is logically impossible for any single observer to observe directly, unless the observer is the whole of the universe. But “self-observation” is meaningless.

Because “state” is expressed in RQM as the correlation between two systems, there can be no meaning to “self-measurement”.

— Wikipedia on Relational quantum mechanics

The Noumenon is a logical implication. It cannot be observed directly. It can be observed partially only, through senses, or phenomena. An observation is an interaction between the observer and the observed.

To really “observe” the Noumenon, all we can do is to observe as many phenomena as possible. In other words, we consider as many observer-observed pairs as possible.

This is because this state would have to be ascribed to a correlation between the universe and some other physical observer, but this observer in turn would have to form part of the universe, and as was discussed above, it is impossible for an object to give a complete specification of itself. Following the idea of relational networks above, an RQM-oriented cosmology would have to account for the universe as a set of partial systems providing descriptions of one another. The exact nature of such a construction remains an open question.

nomenon = all

phe- = part

noumenon = all aspects of the universe

phenomenon = part of the reality of the universe

生疏荒廢

石頭永固 2 || use it or lose it || 不進則退 不用即棄

.

人的腦海之中,有一個「機會成本評價系統」,會自動刪除「沒有用」的才能,以節省記憶和時間資源。

「沒有用」既可以指「本身沒有用」,又可以指「本身有用 但不拿出來用」。對於「機會成本評價系統」而言,兩者沒有分別。

才幹以外,感情亦然。

二次元時間 2.2

Dimension 1.3.2 | Two dimensional time 2.2 | 孖生宇宙 2.2

這段改編自 2010 年 4 月 3 日的對話。

你可以想像,隨著主角多次的「時間旅行」,改變歷史的次數越多,「平行宇宙」的數目亦會越大。假設,主角除了擁有「時光機」,可以「時間旅行」外,他在後來還發明了「平行宇宙機」,令到自己可以,穿梭遊走於各個「平行宇宙」之間。那樣,我們就可以說,「平行宇宙機」連繫了眾多「平行宇宙」。原本的「平行宇宙」,不再完全「平行」。

那樣,要指清一件事件時,除了要指出它發生的時間 —— 例如「2013 年 1 月 14 日 5 時 20 分」—— 外,還要講清楚,它發生在哪一個宇宙的「2013 年 1 月 14 日 5 時 20 分」。原本的時間標籤,是「第一個時間次元」。多重宇宙的標籤,則可以視為「第二個時間次元」。

(安:我覺得有點奇怪。我覺得「多重宇宙的標籤」,既不可以叫做「空間次元」,因為那個標籤或者數字,並不是用來描述「同一個宇宙」中的空間位置;亦不可以叫做「時間次元」,因為「時間」有「因果鏈」的意思。「多重宇宙」是「平行宇宙」,互不相干,沒有「因果關係」可言。)

所以,我剛才視「多重宇宙標籤」為「第二個時間」次元,是建基於「平行宇宙機」的假設。那個科幻故事的主角,發明了「平行宇宙機」,令到自己可以,由原本的宇宙(甲),走到另一個宇宙(乙)行事。那樣,「宇宙甲」的歷史,就可以透過主角,影響到「宇宙乙」的演化,反之亦然。

(安:依你這個講法,除了在科幻小說外,日常現實生活中 —— 如果用比喻 —— 都會有「二次元時間」的現象。)

什麼意思?
