Google (谷歌)為其免費地圖服務軟件 "Google Earth" 又新推出了一個可讓上網者探索太空的功能 "Sky"。
這個 Google Earth 結合了 Google 搜尋衛星圖像、地圖、地形、和 3D 建築物的功能，您可以到它的網站上免費下載。
在 Google Earth 裡，您只要輸入地址，按下「搜尋」，就可以馬上放大所尋找的位置。您也可以搜尋學校、公園、餐廳和旅館的所在，或取得行車路線指示。或用傾斜和旋轉檢視以查看 3D 地形和建築物。或往上探索天際。並可儲存和分享您的搜尋和最愛地點。
這個名為“Sky” 的軟件其實就是一個虛擬的太空望遠鏡。它可以讓用戶瀏覽已被天文學家拍攝到的部分宇宙﹐其中包括大約 1 億顆恆星和 2 億個星系的真實照片。
太空望遠鏡科學研究所的天文學家 Carol Christian 評論說﹕「你將能夠以一種全新的方式瀏覽太空。這些圖片都是太空真實的照片。」
在您下載並裝設完最新的 Google Earth 軟體後，請在“view”(查看)的選單中選取 "Switch to Sky" (切換到Sky)，即可使用該項功能。

- 20 Questions About Vegetarianism
...Excess protein consumption can cause a variety of problems including bone mineral loss, kidney damage, and dehydration. Your body can only use so much protein, the excess is either broken down through oxidization, placing an enormous strain on the kidneys, or it is stored as body fat. Neither option is particularly desirable...

Since the vegetarian diet is the most effective solution to global warming, under Supreme Master Ching Hai's guidance, members of The Supreme Master Ching Hai International Association recently opened a chain of Loving Hut vegetarian restaurants around the world, in the United States, Japan, Indonesia, Au Lac and Formosa. These places provide affordable and high-quality vegetarian delicacies to the public, bringing a positive impact on the food and beverage industry...
Meat or vegetables? Independent online (SA)
A recent study has revealed that giving up meat could drastically reduce one's carbon footprint. A diet with meat is responsible for producing in a year (as many) greenhouse gases as driving a mid-sized car for 4,758 km, the Institute for Ecological Economy Research (IOeW) said last week. But the food a vegetarian consumes in (the same period of time) is responsible for generating (gases only) as driving for 2,427km, the IOeW said in a study commissioned by independent consumer protection group Foodwatch...

The term pleather ("plastic leather") is a slang term for synthetic leather made out of plastic, a portmanteau of plastic and leather, the term can be either descriptive, or derogatory, depending upon the user (the derogatory use implies use as a substitute for genuine animal hide leather to cut costs)...

- Galactic Highway - The Wormhole
- Stream of Time
Wormholes are a valid consequence of Einstein's general relativity view on the universe. A wormhole, in theory, acts as a shortcut or tunnel through space and time. There are several versions on the same theme (i.e. wormholes may link different universes; they may link the two separate locations in the same universe; they may even link black and white holes together), but the physics is similar, wormholes create a link two locations in space-time, bypassing normal three dimensional travel through space. Also, it is theorized, that matter can travel through some wormholes fuelling sci-fi stories like in the film Stargate or Star Trek: Deep Space Nine.
If wormholes do exist however, it is highly unlikely that you'll find a handy key to open the mouth of a wormhole in your back yard, they are likely to be very elusive and you'll probably need some specialist equipment to travel through them (although this will be virtually impossible).
Alexander Shatskiy, from the Lebedev Physical Institute in Moscow, has an idea how these wormholes may be observed. For a start, they can be distinguished from black holes, as wormhole mouths do not have an event horizon.
Secondly, if matter could possibly travel through wormholes, light certainly can, but the light emitted will have a characteristic angular intensity distribution. If we were viewing a wormhole's mouth, we would be witness to a circle, resembling a bubble, with intense light radiating from the inside "rim". Looking toward the center, we would notice the light sharply dim. At the center we would notice no light, but we would see right through the mouth of the wormhole and see stars (from our side of the universe) shining straight through.

Plato argued that time is constant - it's life that's the illusion. Galileo shrugged over the philosophy of time and figured out how to plot it on a graph so he could get on with the important physics.
Albert Einstein said that time is just another dimension, a fourth one to go along with the up-down, side-side, forward-back we move through every day. Our understanding of time, Einstein said, is based on its relationship to our environment.
Weirdly, the faster you travel, the slower time moves. (Is it truely weird? Not quite!!) The most radical interpretation of his theory: Past, present, and future are merely figments of our imagination, constructs built by our brains so that everything doesn't seem to happen at once.
