量子糾纏是咪足以證明世界係虛擬？

Friday invert the mobius strip this time

如果你講人做決定時既因果其實係好抽象既野
而光速（約30萬公里每秒）傳播就係好具體既野 兩樣性質差好遠

例如有人好驚榴蓮陣味（因）而死都唔食榴蓮（果）
用光速去嘗試表達呢pair因果聽落唔太恰當

當佢有日識左個女朋友好鍾意食榴蓮（因）而慢慢變得鍾意食榴蓮（果）
如果你話呢個因果既變化係以光速傳播既話就聽落更奇怪了

In the 1930s, scientists proposed that human consciousness might affect quantum mechanics. Mathematician John Von Neumann first postulated this in 1932 in his book "The Mathematical Foundations of Quantum Mechanics." In the 1960s, theoretical physicist, Eugene Wigner conceived a thought experiment called Wigner's friend — a paradox in quantum physics that describes the states of two people, one conducting the experiment and the observer of the first person, according to science magazine Popular Mechanics. The idea that the consciousness of a person carrying out the experiment can affect the result is knowns as the Von Neumann–Wigner interpretation.

Though a spiritual explanation for quantum mechanic behavior is still believed by a few individuals, including author and alternative medicine advocate Deepak Chopra, a majority of the science community has long disregarded it.

As for a more plausible theory, scientists are stumped.

用比喻都係難明
抽同打開喺實驗過程係指緊邊兩個步驟

其實條link有寫
But the wave function ψ is not a physical object like, for example, an atom, which has an observable mass, charge and spin, as well as internal degrees of freedom. Instead, ψ is an abstract mathematical function that contains all the statistical information that an observer can obtain from measurements of a given system. In this case, there is no real mystery in that this mathematical form of the wave function ψ must change abruptly after a measurement has been performed.

information 傳播唔可以快過光速
所以因果關係唔可以快過光速
可以慢過光速

永恆的零

其實個問題都係返去點解觀察會令wave function改變
上面只係指其實觀察令事件改變並唔係咁稀奇嘅事

唔識就去 YouTube 睇
唔好將你啲 On9 想法當事實咁講

實驗過程有d難科普地用個比喻去指代，但可以咁樣簡單地諗：打開張卡 = 觀察。

打開張卡前，你對張卡既描述，只可以係「50%紅50%黑」；打開張卡後，你就變左100%知道了，打開前後變化的唔係張卡，而係你對張卡既描述。

上面比喻有一個唔妥當的地方，就係宏觀世界張卡本身係已決定的，即張卡本身已經係紅色，只係你未打開；

但量子世界就唔係咁，你打開張卡前，張卡係真真正正既「50%紅50%黑」，係你打開張卡既一瞬間成為100%黑色。呢樣打開卡既比喻，你可以睇Stern-Gerlach Experiment，紅色黑色係比喻緊電子既angular momentum，呢個實驗應該比量子糾纏易明。

如果你真係要再問點解打開果下會有「影響」既話，現代物理學係解釋唔到的，因為物理學家只在乎理論描述到實驗結果，而依家已經成功了，再問落去就變神學哲學，例如你可以用相對論完美描述質量如何令時空彎曲，但你無得再問點解質量有能力「影響」時空。

有興趣嘅可以玩下 quantum information simulator

基礎知道咩係qubit咩係operation可以好多玩法

因果關係係質既改變 - 你整蠱我所以變得好憎你
光速傳播係量既改變 - 重力波以光速（約30公里每秒）傳播

用量既改變去描述質既改變不太相稱 正如你唔會攞把尺去量一個人靚唔靚仔/女

你岩既，但再問就係新物理了，甚至神學哲學，只可以話現代物理學解釋唔到點解wave function會唔同左，而其實大部分科學家都唔會care呢樣野，因為依家已經足夠描述量子世界，再問點解就答唔到、亦無咩科學意義。

例如牛頓萬有引力，描述到質量點樣互相吸引，但你無得再問點用質量可以咁樣「影響」到對方。

真係要解釋就變左新物理學，愛因斯坦相對論，因為質量令時空彎曲。但其實你都仲可以再問，點解質量有咁既「能力」令時空彎曲，咁就真係神學或再等新物理先答到了。

BTW 純粹鳩噏
我覺得物理學家好擅長將任何物理概念講到對一般人嚟講好無聊
可能係因為現代物理好多都係計出嚟，好難落地
令我每次見啲標題越嘩眾取寵，就直覺唔會係物理，係穿鑿附會

咁你可以當人類目前科技未先進到可以唔造成影響下觀察微觀世界

認同，特別係相對論或者量子力學呢d題目，真係要理解既話就只有數學。

一變成科普、比喻，就難免變左質，然後再有d一知半解既人傳下傳下，就會變左咩虛擬世界、精神意識呢d野，例如平時行書局你見到咩人類圖果d書

你可以睇下2022 Nobel Prize果幾個人做既量子糾纏實驗，人地七十年代開始做，一路improve個實驗到依家，基本上都完全排除左實驗儀器既影響了。

實際係點影響到先
你話儀器影響到都係你估㗎咋喎

Ytubers 可能亂講
睇高學歷會好啲

而家係講緊量子糾纏定雙縫？
同埋如果係嘅話最新實驗嘅結果仲係咪好似原先咁 唔觀察係波 觀察就粒子？

有冇睇過Matrix

認真問 有時望緊人/俾人望住會 feel 到， 關唔關量子力學事？

依度嘅因果應該用返物理學個context我諗

當你諗光速係宇宙嘅speed limit
粒子 作用力 photon as a force carrier
同埋宇宙膨脹係可以快過光速等等
咁嘅context下用光速去量化因果似乎會合理

但人同人之間嘅事係以幾何級數咁慢過光速
提到光速的確會覺得好怪同irrelevant
