how big is the universe? is the universe everything there is? where did the universe come from?

Okay considering this scientifically (ie not just assuming there is a God) at the moment no one is sure how the big band happened. However the big bang was the start of time as well as space so it is difficult to talk about before. Some scientists believe that the big band was caused by tiny fluctuations of the vacume. Something like the universe can be forever just by never stopping or by time ending much as it began in a 'big crunch'. It is possible that there is something beyond the universe. M-theory suggests that there are many different dimensional universes floating around in a larger dimensional space. All of these are of course theories the point is to try to use these to make observable predictions which will either support or contradict the theory.

First we have to distinguish between the "observable" ("known") universe and the absolute (all) universe. We can only speculate about the size of the entire universe, but for the observable universe most scientists have agreed that it's 13.7-billion light years in size.

space-time itself originated in the big bang.  everywhere in the universe was once the big bang, and the whole universe was the big bang.  it is actually a common misconception that the big bang occurred at a specific location.\n\nhttp://www.sciam.com/print_version.cfm?articleID=0009F0CA-C523-1213-852383414B7F0147\nhttp://map.gsfc.nasa.gov/m_uni.html\nhttp://universeadventure.org/

No, everything came from a source, but its name was never Jehovah.\n\n"In many cultures it is customary to answer that God created the universe out of nothing. But this is mere temporizing. If we wish courageously to pursue the question, we must, of course ask next where God comes from? And if we decide this to be unanswerable, why not save a step and conclude that the universe has always existed?" ~Carl Sagan

does the universe end?  no one knows yet.  the beginning of the universe is much better understood.\n\nhttp://en.wikipedia.org/wiki/Ultimate_fate_of_the_universe

Big Bang is a theory that tries to explain the formation of the universe, its galaxies, its stars and planets etc.\n\nIt says that the Universe was created by an explosion of a Primeval Atom thus causing it to expand and move away from each other. This was actually based on the Hubble Law which says that Galaxies around us are expanding at speeds directly proportional to their distance from Earth, based on the observation of Edwin Hubble, 1929.\n\nIts a huge topic with lots of technical arguments and counter arguments. Here is the link that will satisfy your quest on Big Bang, atleast for starters...\n\n.:Fishie:.

The universe is big enough to contain over 100 billion galaxies, of which the Milky Way is one. It is also expanding. Since it is growing larger, it can't be infinite, since infinitely-sized things can't become larger than infinity.

Before 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 “\n\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/U... 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. \n\nThis 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\nWhich is the end of expanding universe? That may be determined in 300 billion years, when it stops expanding (like a balloon). If any end exists, what will be behind this end? A multiverse void containing other expanding and contracting balloons, referred to as universes, may exist beyond our own.

Simple question, simple answer, GOD. You think the whole universe came from a dot? If you standing tall enough to see the entire milky way galaxy, our earth is smaller than a dot. Scientists can't understand that. How could you ever squish  the whole universe into a dot? \nAnswer: God created heaven and the earth and all that are in them is. I say this because the BIBLE says so.\nHey!! do you know what universe means?\nUNI-single, VERSE-spoken sentence, single spoken sentence(Genesis 1:1).

at the present time we define the universe by four dimensions, length, width, height, and time.\n\nhttp://en.wikipedia.org/wiki/Spacetime

Universe theories talk about a finite and unlimited Universe. The Universe is unlimited because it has no boundaries. There is no edge, no end where a spaceship would have to stop. See it as a tiny bug walking on the surface of a big balloon. The ballon has a finite dimension, but the bug will never find the end, so it is unlimited from the bug's point of view.\nSo, the Universe can be expanding or contracting or staying the same size. This is a very important question to answer in modern astronomy. Latest studies say that it is expanding, but it has not been totally proved.\nAnd where it is expanding? The Universe is creating more space and time where there is nothing.

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

well... the universe is not infinite or so say today's scientists. according to the parallel universe theory,there are various universes and our's is one of 'em . well one cannot really define the *length* of a universe because it is almost impossible to percieve something that big for the human mind.

On one theory, the space of the Universe (as well as its contents) is what's expanding. That theory says the total amount of space is finite, and that finite quantity just gets bigger every second.  What, you might then ask, is outside of space?  There's no outside!  It's like asking, "What's north of the North Pole?"

The visible universe is supposedly that size because we can see the light from the beginning and therfore base the size on how far light has travelled in the time; However, the universe is not actually that size, since there are areas beyond the Event Horizon which light has not come from yet, and thus the universe is larger than that estimate.\n\n More to answer your point, the universe is expanding at its limits, but as it does so it creates teh space that we as three-dimensional beings can move in, like a dot on the surface of a balloon; If the dot could move anywhere on the surface, it could move all over the balloon, but never cover all of it as it expands. In the same way, the univrese is finite in size, but unbounded in dimension and therefore to practiacl purposes probably infinite.\n\n It's a hard concept and many people have trouble with it.:)

Good question.\n\nIn short... there's no way to really know how the Universe was created.  Some look towards scientific research to explain our origins while many others trust in their faith as the answer. For now, we can only speculate.

There's The Universe, then there's the observable universe. No one knows the size of the first one; it's probably infinite. The second one is the universe with a boundary; that boundary is how far we can see into The Universe, about 13.7-billion light years.
