試想一下,如果人類能夠按鍵即可到達任何地方,甚至是九宵雲外,了解宇宙的森羅
萬象,豈不是很好?因此,不少人渴望擁有這誘人的超能力。究竟瞬間移動只是遙不可
及的憧憬還是有可能成為未來的科技呢?
首先要說明的是,以傳真比喻瞬間移動並不恰
當,因為物質會在一端消失,隨後在另一端出現。
2012年,英國萊斯特大學的四位物理學家估
計瞬間移動是不可能的。他們計算瞬間移動人類
到太空所需的時間和功率,並考慮到了人類基因
組序列,心理數據和錯誤。得出的結論是要傳輸
4.55x10
42
位元(資訊基本單元)的數據。要達到這
目的,就須要4.58x10
15
年才能完成,其間要持續
每小時供電5.76兆瓦 [1]。也就是說當宇宙經歷終
多次循環週期後,數據傳輸還未結束。

the time and power required to telepor t a

bit (basic
unit of information), which took into account
the human genome sequence, mental data
and er ror s due to inter ference. For al l of
this data to be successfully transferred, it is
believed that it would require 4.58x10
15
years
and 5.76 megawatts per hour to power the

points [1]. Sadly, the time necessary for this
communication would be more than sufficient
for the birth and death of the universe many
times over.

Possibility?
