妳/你會過濾多少收到的電子郵件呢? 妳會先確定他的真實性, 然後才傳給別人嗎?

今天檢查我的電子郵件時,看到這樣聳動的標題,從八月起,天空可以清楚的用肉眼看到火星的樣子,這是火星最靠近地球的時候,想看到這樣的情形,恐怕要等到 2278年了。我想,這麼勁爆, 不去查察資料怎麼對得起自己,沒想到在辜狗上面一搜查,原來事情早在兩年前就發生的,不知道哪個渾球,還硬是改了今年的日期,真是的,大家也就這樣不明就 裡的傳來傳去,就在我查了正確的資料後,馬上寫封信糾正自己已經發出去的電子郵件,真是對不起大家啊!

photo : space.comSummary:Email claims that Earth and Mars will have the closest approach in recorded history in August and will be a spectacular site for stargazers. Status:Was true in 2003, but is now outdated. Example:(Submitted, May 2006)
The Red Planet is about to be spectacular! This month and next, Earth is catching up with Mars in an encounter that will culminate in the closest approach between the two planets in recorded history. The next time Mars may come this close is in 2287. Due to the way Jupiter's gravity tugs on Mars and perturbs its orbit, astronomers can only be certain that Mars has not come this close to Earth in the last 5,000 years, but it may be as long as 60,000 years before it happens again. The encounter will culminate on August 27th when Mars comes to within 34,649,589 miles of Earth and will be (next to the moon) the brightest object in the night sky. It will attain a magnitude of -2.9 and will appear 25.11 arc seconds wide. At a modest 75-power magnification Mars will look as large as the full moon to the naked eye. Mars will be easy to spot. At the beginning of August it will rise in the east at 10p.m. and reach its azimuth at about 3 a.m. By the end of August when the two planets are closest, Mars will rise at nightfall and reach its highest point in the sky at 12:30a.m. That's pretty convenient to see something that no human being has seen in recorded history. So, mark your calendar at the beginning of August to see Mars grow progressively brighter and brighter throughout the month. Share this with your children and grandchildren. NO ONE ALIVE TODAY WILL EVER SEE THIS AGAIN!

Commentary: Someone has recently resurrected and sent off this message and it is once again being passed from inbox to inbox. Although the year is not specifically mentioned in the message, recipients may naturally assume that it is referring to the current year, 2005. The events outlined in the message were more or less true back in 2003 although they were a little hyped even then. According to NASA, on August 27, 2003, Earth and Mars were the closest they have been for around 60,000 years. Mars was indeed a spectacular site in the night sky during several months of 2003. However, this fact is not quite as earth shattering as you might think. A 2003 NASA article on the subject explains that:
Much has been made of the fact that the August 27th encounter with Mars is the closest in some 60,000 years. Neanderthals were the last to observe Mars so favorably placed. This is true. It's also a bit of hype. Mars and Earth have been almost this close many times in recent history.
Mars will in fact pass close to Earth once again in 2005, although it will be at its closest on October 31st rather than August 27th. However, the red planet will not pass quite as close as it did in 2003. In 2003, Mars came within approximately 34 million miles of Earth. In late 2005 it will pass at about 43 million miles. In reality, this distance gap will probably not make a great deal of difference to casual observers on the ground. Mars will still be a spectacular and compelling site in the night sky in late 2005 in spite of the fact that it will not be quite as close to Earth as it was in 2003. What's more, these close encounters are not such uncommon events. Thus the claim that "NO ONE ALIVE TODAY WILL EVER SEE THIS AGAIN!" is a little misleading. It is true that the next time Mars will be as close to earth as it was in 2003 will be on August 28, 2287. In the mean time however, there will be plenty of other close approaches, so our children and our children's children are not likely to miss out altogether. Perhaps by 2287 some of our descendents will be observing the close encounter from the Martian perspective.

類似這樣的電子郵件,或是轉記求救的信,說真的在時效上面,是有點値得懷疑的,我通常會先看上面的日期,說起來這次也是有點高興的昏了頭,都還沒有先查證,就急著把電子郵件送出去,以致後來自己查資料的時候懊悔連連。


好的文章,是沒有時效的限制,我也樂於接受。但是像這類的信件,現在的我會好好的看清楚在寄了。畢竟像這樣的大事,一定會有傳媒的報導,如果最近都沒有傳媒在報導,那肯定是哪裡出了錯。
