Multiverse type 3) The many-worlds picture of quantum mechanics. Suprisingly, physicists still don't fully understand how the collapse of the wave function in quantum mechanics happens, and the many-worlds hypothesis makes an attempt at explanation by proposing that every possible alternate timeline for the universe is real and they all happen in an ever-larger, ever-branching way. Like, a universal choose-your-own-adventure where every possible story happens! If this were the case, we might not realize it because we'd be stuck living out just one of the infinitely many possible lives available to us. In some way, many-worlds is similar to the bubble multiverse model by proposing "maybe anything that can happen, does." And we just happen to exist in the series of happenings that were necessary for us to exist." If you're still not convinced by this logic, don't worry, there is not yet any experimental evidence for this kind of multiverse. 第三種，量子力學下的多重世界面相。驚人的是，物理學家尚未完全了解量子力學中波函數崩縮如何發生。這種多重世界假說嘗試對此提出解釋，它提出宇宙每個可能的時間線都是真實的，且以一個更大、更多支線的方式發生。就像你自己的宇宙自由探險，什麼都可能發生！如果是這種情況的話，我們可能不會意識到，因為我們困在無限可能的人生分支裡的其中一種。某種程度上，多重世界就像是泡泡宇宙模型，它們都提出＂所有可能的事都會發生＂。而我們只是剛好存在於，所有一連串生存的必要條件都發生的地方。如果你還是不相信，別擔心，這種多重宇宙也還沒有任何實驗證據呢。 Of course if you want to get imaginative, you could also combine several of these models together into a multi-multiverse, a new super-speculative model based, itself speculative and experimentally unconfirmed models. But that's not to say we couldn't test the multiverse hypotheses. For example, if our observable universe were really just one of many disconnected bubbles or membranes and if it happened to collide with another bubble or membrane some time in the past, then that collision would certainly have had some sort of effect on what we see when we look up at the night sky. On the other hand, the many-worlds interpretation might be tested fairly soon since experimentalists are becoming increasingly able to manipulate and control ever-larger quantum mechanical systems in their labs -- systems that approach the line between the quantum realm and our everyday experience. So as always, we must remember that physics is science, not philosophy; and in our attempts to explain the universe that we observe, we have to make claims that it can in principle be tested -- and then test them! 當然如果你想有想像力一點，可以把這幾種組合在一起，形成一個多重的－多重宇宙。一個全新、不確定、未經實驗證實的，和極度理論為基礎的模型。但並不是說我們不能測試多重宇宙的假說。例如，如果我們的可觀測宇宙真的只是許多無關聯的泡泡或膜之一，如果它們曾經彼此碰撞的話，必定會對我們仰望的夜空產生一些影響。另一方面，因為目前在實驗室裡已更有能力控制量子系統－這些系統處理量子領域和我們日常經驗的界線，所以多重世界的解釋可能很快就可以驗證。如同往常一樣，我們要記住物理是科學而非哲學。當我們試圖解釋我們觀察到的宇宙時，原則上我們的主張必須是可測試的，然後再驗證它！ ***************************************************************** 這次翻感覺沒有什麼問題，但應該是我自我感覺良好。如果前輩們覺得哪些地方翻得不好麻煩說出來，小弟虛心接受，謝謝 :D 補充: 波函數塌縮這部分我是直接複製維基 http://en.wikipedia.org/wiki/Wave_function 不過塌縮的確沒有 suddenly 的感覺在，我再修改一下。 wave-particle duality 我記得高中物理有提到，質量足夠小時波的性質會顯現出來。因為 dunchee 的回文，我又找了其他東西。薛丁格的貓和哥本哈根詮釋來解釋光和粒子的二相性。和觀察對象產生關係會立即造成 superposition 的停止，但如果是 multiverse 就不會有這種事情。這樣看來的話第三種 multiverse 更有平行宇宙的感覺。這種每個有意無意的決定造成宇宙即時分裂的感覺還滿震撼的XD 感謝，很有啟發。:D -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 36.229.84.131
