問題詳情

請依下文回答第 46 題至第 50 題：
Scientists say it could take at least 1,500 years before humans make contact with species of aliens, or for them to communicate with or find us. Astronomers from Cornell University in the USA combined two existing theories about the possibility of life existing on other planets to form a new equation. One of these theories is the Fermi Paradox described by physicist Enrico Fermi in 1950. This states that while billions of Earth-like planets exist in our galaxy, not one has made contact with Earth yet. The other is the mediocrity principle, which suggests that because there is life on Earth, it will typically exist on Earth-like planets throughout the universe.
Study author Evan Solomonides will soon present a research paper on his theory. He said, “We haven’t heard from aliens yet, as space is a big place, but that doesn’t mean no one is out there.” According to Solomonides, extraterrestrials could have received signals from Earth. However, he proposes that ET would not have been able to decipher them. He said they would need to decode the light waves into sounds and analyze 3,000 human languages to understand any messages. He said that signals from Earth have only reached about 8,500 stars and that the Milky Way galaxy alone contains 200 billion stars. He added, “If we stop listening or looking, we may miss the signals. So we should keep looking.”
【題組】46 According to the passage, what might be preventing extraterrestrials from approaching Earth any time soon?
(A) The difficulty in deciphering human languages.
(B) The long histories of 200 billion stars.
(C) The similarity among human and alien species.
(D) The number of planets in the Milky Way galaxy.

【評論內容】科學家表示，人類可能至少需要 1,500 年才能與外星人物種接觸，或者讓他們與我們溝通或找到我們。美國康奈爾大學的天文學家將兩種關於其他行星上存在生命可能性的現有理論結合起來，形成了一個新方程。這些理論之一是物理學家恩里科·費米在 1950 年描述的費米悖論。該悖論指出，雖然我們的銀河系中存在數十億顆類地行星，但目前還沒有一顆與地球接觸過。另一個是平庸原則，該原則表明，由於地球上存在生命，因此它通常會存在於整個宇宙中的類地行星上。研究作者埃文·所羅門尼德斯很快將發表一篇關於他的理論的研究論文。他說：“我們還沒有收到外星人的消息，因為太空很大，但這並不意味著那裡沒有人。” 根據所羅門尼德的說法，外星人可能收到了來自地球的信號。然而，他提出外星人無法破譯它們。他說他們需要將光波解碼為聲音並分析 3,000 種人類語言才能理解任何信息。他表示，來自地球的信號僅到達約8500顆恆星，僅銀河係就包含2000億顆恆星。他補充道：“如果我們停止傾聽或觀察，我們可能會錯過信號。所以我們應該繼續尋找。”
