我本來就不是跟你辯這個，只是想問你有什麼資格說人家嘴砲。還是你是哪屆諾貝爾獎得主.....
但我相信就算諾貝爾獎得主也不敢說沒得獎的是嘴砲.....
Scientific American 2003 年有一篇完整探討多重宇宙的文章，我上 Scientific American 的網站有找到那一篇，只是要付錢才能看。
有興趣你可以自己去找找，但我可以憑著五年前看過一遍的記憶稍微解釋一下你的疑問。
有時候檢驗一個理論，不一定只能用一種方式。
首先空間無限大的問題，重力理論描述宇宙的曲率如果有不尋常的拓樸，就有可能是有限大但沒邊界（如地球表面）。
但經由宇宙微波背景輻射的檢驗，發現有限大的模型並未受到支持，或者受到極強的限制。然而如果是無限大的模型，則可以符合目前的觀測證據。
再來是物質分佈的問題，根據最近星系的立體分佈觀測和微波背景輻射的證據，發現當尺度愈大時，物質分佈愈均勻。而在某個尺度上就...

你說的是:
Parallel Universes. 作者是 Tegmark, Max, May2003, Vol. 288 Issue 5, p41
這一篇嗎 ? 我可以下載的(當然是合法).
==> 稍稍的看了一下該文章. 你的見解應該是從這裡出來的吧.
這一篇後續有不少的 comment喔. 事實上正如我說的. 這樣的理論因為缺乏"證據". 所以不那麼熱門(我個人的見解)
底下附上一個該文的回應:
-----------------------該 parallel 的回應文之ㄧ -----------------------
Tegmark's argument for other universes parallel to ours is inconclusive because of the systematic neglect of an alternative explanation and a shortage of empirical evidence. Tegmark presents four levels of parallel worlds where twins of himself could abide. On Levels I and 1I, his twins are outside our horizon, where we cannot sense them. How, then, does he infer their existence? He does so partly by extraordinary extrapolation beyond the cosmological data into the realm of speculation and partly by smuggling in a key unstated premise. This premise is that our existence is accidental rather than planned. How could science establish such a result? In Level IV, Tegmark introduces his own speculation. If an infinite unobservable entity is needed to explain the unreasonable effectiveness of mathematics, then, as the scientist-turned-priest John Polkinghorne suggests, theism might also be considered.
In all three cases, the evidence supports the conclusion of either many universes or design, but the design option has been suppressed, with a misleading result. Thus, the inference of parallel universes is not "a direct implication of cosmological observations" but requires a crucial implicit injection of ideology.

當然 我對平行宇宙抱持的態度就是觀望與懷疑--- 在沒有證據出現之前都會這樣 不過對於該文的作者. Tegmark Max. 我底下也附上該文中的敘述.
--------------------about Tegmark Max---------------------------------
MAX TEGMARK wrote a four-dimensional version of the computer game Tetris while in college. In another universe, he went on to become a highly paid software developer. In our universe, however, he wound up as professor of physics and astronomy at the University of Pennsylvania. Tegmark is an expert in analyzing the cosmic microwave background and galaxy clustering. Much of his work bears on the concept of parallel universes: evaluating evidence for infinite space and cosmological inflation; developing insights into quantum decoherence; and studying the possibility that the amplitude of microwave background fluctuations, the dimensionality of spacetime and the fundamental laws of physics can vary from place to place.

其實我以為 arXiv 裡面應該有更多的文章才是. 不過那畢竟不是我的領域.
PS: 個人於PRB的文章是有的. 但無關於天文. 因為跟referee打過交道 所以了解: 有幾分證據說幾分話的道理. 畢竟. 沒人想跟點數過不去. "天文我僅懂皮毛而已". 我提問與回答問題 但求客觀與詳細. 有冒犯之處 尚祈見諒.
