Which Stars Are You From?
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.
Waste Lagoon: Circle Four Farms, a Utah-based pork producer, hosts a three-million gallon waste lagoon.
When lagoons like this spill into rivers and lakes as happened in North Carolina in 1995, the result can be environmentally catastrophic. |
Ms. Tzipi Livni is the Foreign Affairs Minister of Israel. On September 17, Golden Year 5 (2008), Ms. Livni won the leadership of the main Kadima party in Israel’s governing coalition. She is now calling for a general election early in 2009 and if elected, will become Israel’s second female Prime Minister and first-ever vegetarian Prime Minister.
