The panspermia hypothesis posits that living cells or their precursors could have emerged on another planet or moon billions of years ago and hitched a ride to earth on a meteorite
「胚種假說」假設：活細胞或其前驅物可能于數十億年前發源自其它行星或月球上，並且搭隕石的便車來到地球。 -
Researchers plan to evaluate the likelihood of panspermia by studying whether microorganisms can survive an interplanetary journey
研究人員打算研究：微生物是否可以在星際旅行中存活，並據以評估胚種說存在的可能性。 -
For this reason, the most commonly discussed panspermia scenario involves the transport of microbes or their precursors from mars to earth
基於這個理由，最常受人討論的胚種說就是：微生物或其前驅物，是從火星送到地球的。 -
For panspermia to occur, however, microorganisms need to survive not only ejection from the first planet and atmospheric entry to the second but the interplanetary voyage itself
然而，胚種說真要發生，微生物除了從第一顆行星噴發、進入第二顆行星的大氣時必須倖存之外，還要能在整個行星際旅程中保住小命。 -
Because it is not possible at this time to quantify all the steps of the panspermia scenario, investigators cannot estimate how much biological material or how many living cells most likely arrived at earth ' s surface in a given period
由於當前無法量化胚種說情境中的所有步驟，研究人員無法估計某特定時期內，可能有多少生物體或活細胞抵達地球表面。 -
If we do find evidence of life on other planets, this will lend weight to the theory of panspermia
假如我們在其他行星找到生命存在的證據，便可進一步印證有生源說理論。
