Question about space?

Galaxies are huge clusters of billions of stars.  Smaller hunks of stars are called "clusters"  -- but once they get really _REALLY_ big, they're called galaxies. \n\nSolar systems are systems of planets and other hunks of rock orbiting a SINGLE STAR...   so, the Earth and the other planets are part of OUR solar system,  orbiting the sun.  Other suns have OTHER solar systems where DIFFERENT planets are orbiting. \n\nThe speed of light is REALLY REALLY FAST. \n\nIf you turn on a light on the moon, no one on earth will see the light for almost two seconds because it took the light that long to get here. \n\nBut the speed of light is _SO FAST_ that even going from New York to Las Angeles, all the way across the United States it only takes about two one-hundredths of a second to get there (0.016 seconds) \n\nThis shows two things, the moon is a LONG ways away,and light is VERY VERY FAST.  The speed of light is 186000 (one hundred and eighty six thousand) miles per second.  A rifle bullet travels only around two to three thousand miles per hour.  So, light is two hundred thousand  times faster than a speeding bullet.  Really REALLY fast.

Hey I don't wonder about space rather its quite a bit interesting to wander in the space.....Its known journey began from Big Bang.....Our Universe is just 156 billion light years wide.....so keep wandering beforing it comes to an end.....

There currently is a "limit" to space; however, the universe is still expanding from the Big Bang, so the edge of space is constantly moving away from a central point. Beyond this, there is nothing, but unfortunately, this is almost impossible for our brains to conceive because the laws of physics that make up our known world do not exist outside the known universe.

Space was created during the Big Bang, the creation event of this Universe. But space is still constantly being created even now, since the expansion of the Universe is now still ongoing and actually accelerating.

Hi, \n \nSince you have asked "How", I would say the best place to start would be one of the text books. Thats because they always have things in the right sequence. \n\nAlso, you can find almost anything you want to learn about Space on internet. A good place to start would be \nhttp://www.answers.com/topic/space-science?method=6\n\nHere there are a lot of links. Also, any term that you don't understand can be easily researched, as links for terms are also given. \n\nDo not forget to use www.google.com, when in doubt.\n\nHappy Reading! \nAll the best.

It is all throughout space if it exists.  You can't see it because...well...it is dark ;0)

There are ways of calculating the average mass and the size of the universe, but so far nobody there have been several flawless answers that don't agree with one another.\n\nThe answer is going to depend on what shape space is. Gravity is going to work differently in flat space, positively curved space, or negatively curved space. At the tiny, tiny, tiny level (say, a planet or moon), gravity is just going to pull you to the closest physical body. Even on the slightly larger level (a star and its planets), gravity is pretty constant. But when you start looking at the effect of galaxies on one another, and those wacky and inexplicable quasars way the hell out there, suddenly the principles of gravity that seem to simple are breaking apart!\n\nSo is it infinite? Go find an answer you like, and there's probably good evidence to support it. Does the universe stop? That's most likely true, but if you go to the edge of the universe, then the edge of the universe won't be at that point anymore. So again, find an answer you like and be happy with it, because nobody can prove you wrong!

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

Even if we define "space" as everything from the ground up, we still only experience a pressure of about 1 kg per square centimeter. That's the pressure--or weight--of Earth's atmosphere. Beyond the atmosphere where empty space lies there is virtually no pressure.\n\nGod is spelled B-I-G B-A-N-G\nPBrax@netscape.com

Space consists of nothing!\n\nSpace is mostly empty, with a spattering of matter in the form of galaxies, which are drifting further and further away from each other as time moves in the +ve direction.\n\nMatter and energy are mutually convertible.\n\nTime is the fourth dimension, and an important function of entropy or the running down of things.\n\nAs time moves in the +ve direction i.e. forward, entropy increases, things get run down and the energy dissipates over the expanding universe, as does matter, that means that as time goes by, the average density of the universe as we know it reduces, the matter-energy per unit area also reduces.\n\nAs time moves backward, entropy reduces, the space reduces to a point and matter and anti-matter coalesce to nothingness.\n\nst

All the techno babble apart - space has no end.\n\nThere is a distinction between space and universe. When talking about space in common man's language we talk about what is outside earth's atmosphere. That space has NO END. It is infinite in all directions and contains the moon, the planets, the sun, the starts, the galaxies, our universe formed after the big bang and beyond (probably several more universes formed of separate big bangs that are dying or forming like stars do).\n\nNow about a sphere's surface having no end but an area, well this has nothing to do with end of either universe or space or a sphere.. when viewed from the center of a sphere, a line drawn in any direction will intersect the surface of the sphere and therefore the entire surface of the sphere is an end. Space on the other hand has no end, it extends out to infinity.\n\nA simple way of understanding this is imagine you are in a room in a building. The room ends with the walls, but beyond the walls there is something - maybe more rooms. The rooms end with he building's walls but even beyond that wall there are more buildings. There is no end, if you imagine an end and if you could stand at the end there would still be something beyond that end more empty space maybe. No matter how large a number you imagine there is always something bigger. Numbers just like space go till infinity.

If all matter is over 90% empty space, then there should theoretically be small vacuums throughout the entire universe.  However, such a vacuum would be impossible to detect, contain, or sustain.\n\nPerhaps beyond the edge of the universe, a perfect vacuum exists.  All the matter/energy ever can only take up so much space.  However, there is no way to observe or reach that vacuum either.\n\nMmmm... uncertainty!

Yes there is a relation between nuclear and space, infact space affects everything... The advancements we can really explain here in small space. Just go thru google search and find out.

Just supose that the universe end in some point, that has a boundary. What would be outside? Nothing? And... what is between Mars and the Earth? Also nothing. The universe is... "the nothing", and never ends. Anyway, and suposing that you forget the relativity theory and you want to know where is the star/planet/thing that is farest from the "centre", you can say that the radius of the universe is less or equal to the speed of light times the age of the univers.
