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.
據(jù)科學(xué)家表示,若想和外星人取得聯(lián)系,或要讓他們發(fā)現(xiàn)我們至少要等1500年。來自康內(nèi)爾大學(xué)的天文學(xué)家將兩個(gè)“外太空生命”原理結(jié)合在一起,形成了一個(gè)新的等式。原理之一是1950年物理學(xué)家恩里克·費(fèi)米提出的費(fèi)米悖論。費(fèi)米悖論指出,銀河系內(nèi)存在著數(shù)十億個(gè)類似地球的行星,但尚未有行星與人類取得聯(lián)系。另一個(gè)是平庸原理,它指出因地球上存在生命,宇宙中其它類似行星也存在相關(guān)的自然過程。
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 analyse 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."
研究作家埃文·索洛莫尼德斯不久將發(fā)表研究報(bào)告。他認(rèn)為:“我們尚未與外星人取得聯(lián)系,宇宙之大無奇不有。”據(jù)索洛莫尼德斯表示,外星人很有可能收到過地球信號(hào)。但他認(rèn)為目前外星人還無法破譯。稱外星人需要將光波破譯成聲音,通過分析3000種人類語言來了解信息。他認(rèn)為地球信號(hào)所能遍及的范圍約8500個(gè)恒星,但光銀河系就有2000億個(gè)行星。他補(bǔ)充道:“如果我們停止觀測,我們就會(huì)錯(cuò)過外太空信號(hào),我們要做的是繼續(xù)觀測。”
