The Universe comprises everything we perceive to physically exist, the entirety of space and time, all forms of matter and energy. However, the term Universe may be used in slightly different contextual senses, denoting such concepts as the cosmos, the world, or Nature. The word Universe is usually defined as encompassing everything. However, using an alternative definition, some have speculated that the "Universe" composed of expanding space-as-we-know-it, is just one of many disconnected "universes", which are collectively denoted as the multiverse. For example, in the many-worlds hypothesis, new "universes" are spawned with every quantum measurement. These universes are usually thought to be completely disconnected from our own and therefore impossible to detect experimentally. Observations of older parts of the universe (which are far away) suggest that the Universe has been governed by the same physical laws and constants throughout most of its extent and history. However, in bubble universe theory, there may be an infinite variety of "universes" created in various ways, and perhaps each with different physical constants. Throughout recorded history, several cosmologies and cosmogonies have been proposed to account for observations of the Universe. The earliest quantitative geocentric models were developed by the ancient Greeks, who proposed that the Universe possesses infinite space and has existed eternally, but contains a single set of concentric spheres of finite size – corresponding to the fixed stars, the Sun and various planets – rotating about a spherical but unmoving Earth. Over the centuries, more precise observations and improved theories of gravity led to Copernicus's heliocentric model and the Newtonian model of the Solar System, respectively. Further improvements in astronomy led to the characterization of the Milky Way, and the discovery of other galaxies and the microwave background radiation; careful studies of the distribution of these galaxies and their spectral lines have led to much of modern cosmology. This high-resolution image of the Hubble ultra deep field shows a diverse range of galaxies, each consisting of billions of stars. The equivalent area of sky that the picture occupies is shown in the lower left corner. The smallest, reddest galaxies, about 100, are some of the most distant galaxies to have been imaged by an optical telescope, existing at the time shortly after the Big Bang.According to the prevailing scientific model of the Universe, known as the Big Bang, the Universe expanded from an extremely hot, dense phase called the Planck epoch, in which all the matter and energy of the observable universe was concentrated. Since the Planck epoch, the Universe has been expanding to its present form, possibly with a brief period (less than 10 seconds) of cosmic inflation. Several independent experimental measurements support this theoretical expansion and, more generally, the Big Bang theory. Recent observations indicate that this expansion is accelerating because of the dark energy, and that most of the matter and energy in the Universe is fundamentally different from that observed on Earth and not directly observable. The imprecision of current observations has hindered predictions of the ultimate fate of the Universe. Current interpretations of astronomical observations indicate that the age of the Universe is 13.73 (± 0.12) billion years, and that the diameter of the observable universe is at least 93 billion light years, or 8.80 × 10 metres. According to general relativity, space can expand faster than the speed of light, although we can view only a small portion of the universe due to the limitation imposed by light speed. It is uncertain whether the size of the Universe is finite or infinite. From Wikipedia under the

Thanks? Q. I've got an audition for a musical and I want to know if singing songs from Across the Universe would be appropriate? There is sheet music for it. Asked by jennjenn:) - Wed Aug 5 12:12:43 2009 - - 2 Answers - 1 Comments A. I'm going to have to go with no. Generally you want to avoid songs from movies (especially since these are Beatles songs) You're going to want to go with an actual showtune, unless they are asking for a pop or rock piece. Answered by Megan - Wed Aug 5 14:22:42 2009 How does the Hubble telescope see the universe in the past? Q. I read that the Hubble has taken pictures of the earliest form of the universe that it has ever gotten, 600 million years after the Big Bang. If the universe now is somewhere like 32 billion years after the Big Bang, how does that work? Be kind for my ignorance. Asked by shaebug - Wed Jan 6 11:41:07 2010 - - 7 Answers - 0 Comments A. All light you see is from the past, because light takes time to go somewhere. It's just for most objects we look at, that time is relatively short. Light from across the room (say 3 meters away) takes 10 nanoseconds to get to you. So what you see is not what is happening right now, but what happened 10 nanoseconds ago. Of course, that's such a short time that for most purposes it makes no difference at all. (It makes a difference for atomic clocks, which do keep time down to the nanosecond. A clock in the US trying to synchronize with a clock in Europe has to account for the fact that it takes millions of nanoseconds for the message from the clock in Europe to get here). Light takes a little over a second to get here from the moon.

Q. Physicists have shown that the universe will eventually "die", probably through lack of heat and light millions of years in the future. What ultimately is the point of humanity if the universe will eventually die? If humanity still exists then, what would we do? Asked by KatGuy - Sun Dec 30 16:44:34 2007 - - 9 Answers - 0 Comments A. What an interesting synchronicity- I heard Proff. Michio Kaku talk about it on Coast to Coast AM today. He said that until this time comes, we will probably (unless we annihilate ourselves first with A bombs) have the technology to "burst" this universe buble and junp to a parallel universe. A very interesting idea, has plenty of meat for SF authors probably. But in my opinion humanity shouldn't have any artificial purpose- whether you like gardening or going to church or hanging out with friends or enjoying in Vegas. For each man should find his own path because, as Aleister Crowley wrote (and many existentialists said a similar thing): Every man and every woman is a star. Answered by Rasputin1916 S - Tue Jan 1 17:51:05 2008 From Yahoo Answer Search: "universe" The universe is often used as a blanket term for quite literally everything that exists. In strictly physical terms, the total universe is the sum of all matter that exists and the space in which all events occur or could occur. Sourced
