What is the universe and what is it made of?
819436
There are only about 100 kinds of atoms in all the Universe, and whether these atoms form trees or tyres, ashes or animals, water or the air we breath, depends on how they are put together. The same atoms are used again and again. Structure determines not only the appearance of materials, but also their properties. \n\nOur universe consists of all known mass, energy, space, and time. Evidence suggests that our universe began as an incredibly hot and dense region referred to as a singularity. The science called cosmology studies and hypothesizes on how the universe has evolved from singularity to its present as well as possible future states. The dominant theory of universal evolution goes by the familiar name of big bang (or big bang cosmology). At its simplest the big bang refers to a explosive expansion of the entire universe, starting from singularity and continuing to today. Thus, the big bang encompasses all of the events in our universe that have occurred subsequent to singularity. Particularly, all of the energy and mass in our universe was formed within and subsequent to singularity. Every atom that ever was and every atom that ever will be (such as those in our bodies) was created in the course of the big bang.

Creation! The meaning of life is what you make of it. The universe is what is there for you to discover. and everithing is what you live for. put them together and the answer is the same: CREATION

in its present form, it can't describe the state of the universe at time=0.  Thus, it doesn't answer the question of where did all the mass and energy come from

The Universe was created by an event known as the "BIG BANG" and has been increasing ever since.  There are many theories about what the universe will do in the future Ex. ever increasing, saddle shape, or will is contract and implode creating a massive black hole.\n\nVery cool and interesting stuff.\n\nCheck this site for more on the "BIG BANG"

In physics, matter is commonly defined as the substance of which physical objects are composed, not counting the contribution of various energy or force-fields, which are not usually considered to be matter per se (though they may contribute to the mass of objects). Matter constitutes much of the observable universe, although again, light is not ordinarily considered matter. Unfortunately, for scientific purposes, "matter" is somewhat loosely defined.\n\nSee http://en.wikipedia.org/wiki/Matter for more information on matter.\n\nGood Luck!!!

Is our universe in another universe?  \n\nBefore we can address that question, we must first define universe.  \n\nThe word universe denotes all space and everything (matter, energy) contained within it.  The prefix uni means one.  The root verse means word, carnate message, meaningful substance, matter.  Questions regarding our universe persist today.  Does it have a beginning and end, or does it go on forever and ever?  Is it linear or curved?  If it has limits of length or curvature, then what lies beyond the Universe?  If something lies beyond the Universe, then can’t we accurately call that the Universe?\n\nSome lay people and some scientists conceive of the universe as infinite space.  Others define the universe as finite, or limited (perhaps curved), space.  Still others incorporate the elements of matter and/or energy into their definition of the universe, as opposed to the space beyond matter and energy.\n\nGiven these concepts of our universe, some scientists conclude that the “totality of space could be infinite. Shrink an infinite space by an arbitrary amount, and it is still infinite. (Scientific American March 2005).”  \n\nAs to the notion that we live in an ever expanding universe, moving away from every other universe on the fabric of space-time, some scientists are careful to point out that “\nAndromeda, our nearest large galactic neighbor, is actually moving toward us, not away. Such exceptions arise because Hubble's law describes only the average behavior of galaxies (Scientific American March 2005).”\n\nIn accordance with your supposition that our universe is in another universe, “it has been hypothesized by some scientists that the universe may be part of a system of many other universes, known as the multiverse (http://en.wikipedia.org/wiki/Universe).” Modern astrophysicists talk about multiple "pocket" universes that branch off from one another.  Stephen Hawking points out that parallel pocket universes can have no effect on a real observer inside a single pocket, so, according to Hawking, they are theoretical baggage that should be eliminated from cosmology, the study of the origins of the universe.\n\nSome string theories define the universe as a three-dimensional space in an invisible space having more dimensions. This is, in essence, a universe within a universe.  Our zone, a “braneworld” could periodically bounce into another parallel braneworld.  This may create what would appear as a Big Bang from one perspective or a Big Bounce of alternating expanding and contracting universe from another perspective.  Such a cataclysmic event is thought to occur 300 billion years from now, resulting in the rearranging and creation of a new universe.\n\nIs our universe inside another universe?  Well, apparently the Men in Black had it right.  Our universe seems to be inside of something else, another universe, called the multiverse.\n\nSteve\n:-D

the universe is a giant monkey.  We are just a part of a galaxy which is a little blood cell inside the monkey.

Science endevours to reach the truth through experiments and logical analysis-the truth about the origin of the Universe and the cause behind this creation.How this Universe came into being and when,what was there prior to the creation,Is there any God who presided over this creation,whether  the Universe is finite or not-these are some of the fundamental questions that science attempts to answer.

Well, if you want to break it down even more, the universe only consists of minscule, vibrating strings.  At least, that's the most widely accepted theory in fundamental physics right now.\n\nThe beauty of it all is how much complexity can arise from such simple fundamentals.

Actually there is only one universe which encompasses everything: "All matter and energy, including the earth, the galaxies, and the contents of intergalactic space" - http://dictionary.reference.com/search?q=universe\n\nThe earth is part of a galaxy which we call the 'Milky Way'.

The universe is full of surprises.  Things have baffled us in the past, and will continue to alter your current understanding of the universe.  The theory of the Holographic universe may be our current understanding that the whole is contained is every part that makes up the whole.  Every atom is a universe, and every universe is also an atom.

Universe in general is the area of everything including earth, solar systems, nebulas, black holes, galaxies etc are contained within. Everything that is observable to us(human) are so far within this universe. So maybe there are more but to human.. there is only 1.

Physical cosmology is the branch of physics and astrophysics that deals with the study of the physical origins of the Universe (the Cosmos) and the nature of the Universe on its very largest scales.

The correct answer is that no one knows.  We don't even know what most of the universe is made of (right now it's being called dark matter, because all we know about it is that we can't see it).\n\nIf I had to make a bet, I would go with total energy equals zero.  \n\nThere is a lot of matter in the universe, as everyone is saying, and that makes for a lot of mass energy.  But, the flip side is that there is a lot of mass in the universe, and that makes for a lot of negative gravitational potential energy.  It is possible they cancel.

It seems that our universe is all matter, space, and energy that we can perceive in this closed system.  However, that does not mean that there is not additional matter, space, and energy outside our universe.  In other words, there are probably other universes.  Therefore, the zone that we call our universe (or braneworld) may be moving through or expanding into other universes (or braneworlds).  In sum, all universes may be moving through a multiverse.\n \nSteve\n:-D
