How can outer space never end?  It's weird to imagine!?

space is either is behind human comprhension whether it is infinite or not. if it is infinite, it is too rgeat to comprehend, if it stops, it's even harder to comprehend what's beyond that. it could be anything. does time stop? does space stop?

The universe has no end, just as the surface of a sphere has no end. In terms of the surface you can't describe its end, only in terms of a higher dimensional geometry. In that sense, "beyond" is meaningless since it is a term to relate to the same dimension as the universe. It's like "beyond the end of the world" for the surface of Earth -  there is no end, and at some time you might return to where you started from.

definitely, I mean so many people are so wrapped up in our lives that although we know there's outer space - we never think about it. It would be gr8 to know there are other things going on than what we can just see. Aliens (cos that's what they'll be even if they have two feet and two pairs of eyes etc) mark a whole new "time" for us - the potential to discover new things there may be things that could help us have a better quality of life that others have discovered that we haven't, to udnerstand more of what is going on around us. We think that knowing my stuff works is not important, but it definitly is... too many people live in ignorance and take things for granted.

Time is infinite, the end will never come.

No that assumtion is wrong. Space is continuinly expanding, so therefore people will assume it is infininte. Leaving religion out of it, space we know was created by a big bang, I find that hard to believe, not for religious reasons but I see it phyisicaly impossible. It is not infinite, just very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, big

yeah, i guess it could wrack almost anyone's brain.  spacetime is not infinite.  it is finite yet has no edge.  it may be something like the two dimensional surface of a sphere.  nothing inside or outside the sphere exists for the surface.  nothing exists outside the universe or before the universe.  i have something else for you to think about.  the universe is 13.7 billion years old, yet we can observe parts of the universe that are about 46 billion lightyears away.\n\nhttp://en.wikipedia.org/wiki/Big_bang\nhttp://map.gsfc.nasa.gov/m_uni.html\nhttp://www.sciam.com/print_version.cfm?articleID=0009F0CA-C523-1213-852383414B7F0147

It depends on which space you are referring to. Common people refer to space as the void in which everything else is contained. This space is infinite.\n\nScientists commonly think of space as a fabric acting like a balloon which is being blown into and expanding. At a given moment, this three-dimensional space of our universe is finite (having an end), although two-dimensional travel through space fabric is thought to be curved (and therefore endless). This balloon that scientists refer to as our universe containing what they call space is defined as being one of many universes moving in a larger multiverse. This multiverse is very similar to what most people would call space and may well be endless.\n\nIn sum, lay space never ends, but scientific space does.

It doesn't end.  It goes on. If you took a line and ran it in any direction off the planet's surface it would just keep going into infinity,  if you could freeze time and walk on that screen,  you would never get to the end.  There is no end.

The Universe cannot be infinite, because it is expanding, which points to its origin where everything began at the same point, namely the singularity of the Big Bang.  Therefore, if it is expanding, it is bounded.\n\nHowever, it is thought that it probably doesn't have an edge, much like the Earth doesn't have an edge.  If you started in a spaceship and went in a straight line, you would eventually end up where you started, much like if you started at the North Pole and went in a straight line, you would end up back the North Pole.\n\nThe reason: although you would be going in a straight line on the 2-D surface of the Earth, that line is curved in the 3rd dimension.  So, if spacetime is curved in the 4th dimension, you could be going in a straight line 3 dimensionally, but it would be curved 4th dimensionally.

I believe the universe is a 'closed' shape, meaning that there is no 'edge', however it does have a finite size.  But just to entertain your question, if we one day did reach the End of the Universe we literally would be unable to describe anything on the otherside.  Everything we know about physics, space time, the fundamental forces, the universal constants and so on only exist in this universe.  Anything 'outside' of the universe could potentially then have different laws of physics and thus would be completely beyond our comprehension.  Words would literally fail.

u know wot!space doesnt even have enough air to carry sound waves !so lifeforms we know have no damn way sustaining their life in space!\n\nbut , there is oxygen in space, however, the majority of it has already \nbeen captured gravitationally by stars, planets, or other celestial bodies.  \nSo space is almost a perfect vacuum, but gas and dust particles do float \naround out there.  These particles are referred to as the interstellar \nmedium by astronomers.  \n\nAccording to Thomas Arny's "Explorations: An Introduction to Astronomy," if \nwe were to compare the amount of gas in interstellar space to the air we \nbreathe, it would be like "one marble in a box 5 miles on a side compared \nto the same box filled completely with marbles."  So needless to say, there \nisn't very much oxygen in outer space, but there is some.  And the reason \nthere isn't more is simply that the gravity of all the other various \ncelestial objects out there, including galaxies, has captured most of the \ngas and dust.\n\n\nbut universe is so large , who knows there could be other places where air could be found even then i seriously doubt the presence of enough oxygen\n\n\nAstronomers have detected the first presence of oxygen and carbon in the atmosphere of an extrasolar planet, a world already known to be venting massive amounts of gas into space. \n\nThe find is evidence of an atmospheric "blow off" in action, where energetic hydrogen gas drags heavier elements along for a supersonic ride into space.\n\n\n\nDespite the oxygen, the faraway planet is not one that would support life.\n\n\nThe Jupiter-like planet is officially called HD 209458b, tcalled  Osiris after an Egyptian god who was dismembered by his brother Seth. It orbits a Sun-like star 150 light-years from Earth. \n\nAstronomers already knew the planet was rapidly losing its atmosphere after they  found it spewing out enough hydrogen gas to create an envelope that extended and trailed the extrasolar world. \n\nThe planet was thought to be losing at least 10,000 tons of material each second, but researchers weren't sure the process was powerful enough to dredge up heavier elements.\n\nCarbon and oxygen atoms are 10 times heavier than those of hydrogen, and therefore would normally lie low in a planet's atmosphere. So a force stronger than gravity is driving them up along with the hydrogen gas into the extended envelope around this planet\n\n\nThe venting process has been attributed to a pair of reasons, namely the intense gravitational forces between the planet and its parent star, as well as the super-hot temperature of the planet's atmosphere. HD 209458b circles its stellar parent every 3.5 days from a distance of just 4.4 million miles (7 million kilometers), which is closer than Mercury's orbit around the Sun.\n\nThe tight orbit causes intense gravitational tiding that stretches the planet's atmosphere into an oval shape, not unlike a rugby ball, which can allow gas to escape. The upper atmosphere itself is baked up to 18,000 degrees Fahrenheit (10,000 degrees Celsius), which forces hydrogen atoms to expand outward at supersonic speeds. \n\nThe hydrogen wind erupts away from the planet like a geyser and is powerful enough to sweep up carbon and oxygen with it. \n\nThe planet may eventually shed its entire atmosphere, leaving behind only a solid core remnant of its once massive self.  \nThe process is similar to one that may have eventually produced the atmospheres around more local planets, such as Venus and Earth\n\n\n\nHD 209458b orbits a star in the constellation Pegasus, which can be seen with binoculars from the ground. The planet was first detected in 1999 using the wobble method of planet hunting. A separate team of astronomers previously detected sodium in the planet's atmosphere as well\n\nso maybe u r not so silly after all ,as this is a question to be answered satisfactorily answered!!

well unfortunately, outerspace is a whole lot of nothing, so it doesnt have to take up any space.  granted there are molecules floating around out there, but for the most part there isnt any matter in empty outer space

if only someone really knew, I think the universe never ends.  I would really hope that we would find new planets outside our own solar system and we would really find other planets like Earth.  I still have time to pay attention and hope they continue to explorer.

This is an interesting idea, and yes it is plausible.  Unfortunately, there is no way for us to surmise whether or not it is true, so this is something that can never make the status of a scientific theory.  \n\n(Misconception: most people think a theory is just an idea, but a true scientific theory must stand up to experimental scrutiny in order for it to make the status of a theory.  Since this concept is impossible to test or verify, it can never be a theory, and must stay in the realm of ideas and friendly debates.)\n\nHere is another cool thing to consider:\nThe Universe cannot be infinite, because it is expanding, which points to its origin where everything began at the same point, namely the singularity of the Big Bang. Therefore, if it is expanding, it is bounded.\n\nHowever, it is thought that it probably doesn't have an edge, much like the Earth doesn't have an edge. If you started in a spaceship and went in a straight line, you would eventually end up where you started, much like if you started at the North Pole and went in a straight line, you would end up back the North Pole.\n\nThe reason: although you would be going in a straight line on the 2-D surface of the Earth, that line is curved in the 3rd dimension. So, if spacetime is curved in the 4th dimension, you could be going in a straight line 3 dimensionally, but it would be curved 4th dimensionally.\n\nHowever, one could look at it this way instead: The Universe does have a definite edge, but as ou approach that edege, you and everything else shrinks, which means you could never make it to the edge.  You wouldn't be aware of the shrinkage because even the measuring devices would be shrunk, so you would think you were going endlessly in a straight line, when in reality, you were approaching an actual finite edge, but never making it.  Again, it can never be tested, so just a thought ;0)

It does not end and its growing, before you try tackling such a question, answer the micro-level questions of the same kind.  The universe encompasses all that exists, and by default then, it is largely unknown.  We don't know where the universe ends, and all evidence points to it being endless and growing, therefore we make a conclusion based on a portion of the information actually needed.

Space is infintie.  The universe,however, is not.

it's never ends like universe.it is also vast
