Another world?

Question

I always wondered to myself, what is outside space? outside of the planets, does it go on and on forever, or does it stop at some point? what it outside the space and galaxy? Doesnt this make you think? Maybe is there another world out there that we havent seen? You know how theres an area of planets and stuff? what is outside those walls? So you just passed Pluto on your spaceshuttle, and what if you decide to keep going, what will happen? is there something more out there that no one has found?

I know about the Kupiter Belt, and the Astroid Belt, i learned that all, im saying something that NO ONE has discovered yet, something that NO ONE has seen before, not scientest, NO ONE, this is a kind of question that makes you think, i want your opinion, im not asking about whats there.

Answer 1

Outside of Pluto, you reach the Kuiper belt, which contains a lot of Pluto-like objects. Beyond that, you hit the Oort cloud, which surrounds our solar system. Then it's a lot of emty space for a long time, because even though there are 200 billion stars in our galaxy, they are pretty far apart. Most of these stars have solar systems of their own. Outside our galaxy, there is the local group of ~40 galaxies (only one other nearly the size of our own, the others smaller), and then you get other clusters and superclusters of galaxies. You should look into more astronomy - we know quite a bit about the universe! And it's really cool.

Answer 2

Oh, for sure! There are undoubtedly countless worlds out there that we have never seen, (or ever will see). It is not unreasonable to believe that life may exist elsewhere. At least not until someone can give a good explanation for why life here would be an isolated event. It may even be abundant right here in our own galaxy. There are, roughly estimated, something on the order of 10 to 100 billion billion stars. Perhaps one percent of these are single stars like the sun. Many, even most, of them probably have planets.
If you fly past Pluto you would spend thousands of years in space before crossing any other star systems like ours. Better take along something to occupy yourself. Our best bet would be to listen for radio transmissions from outer space. So far, no intelligent signals have been detected. Looking kind of bleak, so far, I would say.
And there is nothing outside of space. There isn't even an "outside" where the Universe is concerned. Our solar system is one tiny aggregate in a huge galaxy of a couple hundred billion stars. And that galaxy is just one of hundreds of billions.

Answer 3

Well I hope your ready to read a lot. I guess the short of it is once you travel the distance across the Milky Way (even the short way out from our outer spiral arm) there are the intergalactic regions and a billion other galaxy's. But as the universe is still expanding you probably won't catch up to it. Beyond that, a good theory to invest time in is the concept of Membrane Theory which describes our universe as being created from the meeting (and resulting Big Bang) of dimensional membranes (accordingly math predicts 11 dimensions). Below is a site which discusses an excellent NOVA program which gives excellent dialog and visuals to help understand this subject. See it. It is a must!

Answer 4

well well, someone who dreams like i do. my perception of space is that it has a distance farther than we can find numbers for. if you consider the void, the empty space in which all of creation exists, you will find yourself confounded like i am. i am sure that space, or i like to use the term void, goes on forever. there is no time nor distance to measure it except infinity. void is actually nothing, and at one point in time[ and i use the word loosely] it was completely empty and dark. consider that if it were to have an ending, what is on the other side. so it must be forever. if it had a starting point, then what was there before it started. look at the time it must have taken to go from complete emptiness to what it is now a grain at a time. and where did that little grain or gas come from. it appears to progress from absolutely nothing to something. our minds cannot fathom these things, but i am fascinated with the wonder of it all. and there is no one who can correctly explain it to me. whew. maybe we better let god do the creating and let it go at that. I sure cannot figure it out. but it is fun trying.

Answer 5

where does a circle start and finish.we could be looking along our own circle. think if we could travel or even see far enough , might we see ourselves. and if the universe were like an elastic band ball ( that some people make ) with each band going in differant directions to make up a solid object then the universe might never seem to end

Answer 6

Even the most conservatively absurd calculations predict that there are at least 40,000 possible life sustaining planets within our very own Milky Way Galaxy.

It seems rather naive to assume we are alone.

Answer 7

there's a lot of planets and galaxies out there...they're not just for decoration u know...i think that we're not the only ones in such a huge universe. Of course there's another worlds and people.

Answer 8

Dear Lady With Question:

That is an interesting question that you have. Almost one out of every ten young people that come to Yahoo Questions and Answers asks the same thing, and no one bothers to search the previous answers given. So...folks like me have to answer the same question over and over again. It gets tiring after a while.

BUT, since you in particular asked in such a nice way, here goes...

We live on the surface of the Earth. The Earth is a planet; one of nine, by the way, which circle around a central star called the Sun. Some of the planets have moons and some do not.
Some of them even have more than one moon just to make things interesting. And, to further make things fun, there is an
argument going on about the reasonableness of calling Pluto, the smallest and fartherest planet from the Sun "a Planet." So,
there might be 8, or there might be 9 planets circling the Sun, depending upon who you listen to. The Sun with the 8 (or 9)
planets and all their associated moons are called our Solar System (ours, because it is the one we live in).

Our Solar System is located within the Milky Way Galaxy which is more or less all that you see when you look up into the sky on a clear night with your naked eyes. The Milky Way Galaxy is comprised of some 200 Billion Stars. There is not
an exact count because of the overall quantity of them out there. A lot of the more interesting ones have been named or numbered by star gazers over the years and if you look for them, catalogs exist telling you all kinds of neat information about each of them. And, each one of those stars might have from 0 to 10 (or more) planets with their associated moons circling around it.

The Milky Way Galaxy is shaped like a huge disk that is
1500 Light Years wide and about 1.5 Light Years thick. At the center of the disk is a conglomeration of tightly packed stars which give off an erie brightness that rivals the brightness of any individual star we can see out there. For reasons beyond the scope of this brief reply, many people suspect that at the very center of this disk lies a "black hole." Spiral arms reach out from the center of this disk to the fringes of the galaxy. These spiral arms are made up of groupings of stars with the space in between arms being rather empty of significant objects.

The Milky Way Galaxy is only one of thousands or other galaxies out there beyond the bounds of the Milky Way.
Each one of those galaxies may have as many as 200
Billion more stars within it. And, yes, you are correct, each of those stars could have from 0 to 10 (or more) planets (with their associated moons) circling around it just like our Sun does.

So, outer space is really big. In fact it is bigger than most people can easily comprehend. At this time the only size
statements being made are references to what we can now see with our most sophisticated optical and radio telescopes located both on the Earth's surface and out in space. Those instruments can see objects in space out to a distance of 40 Billion Light Years in all directions from Earth. We cannot obtain any useful information from our present day equipment designs beyond that distance. That does not, however, in any way suggest that space stops there. We just cannot see any farther than that. And, thank goodness, we really cant tell you what is beyond that because we just don't know. The idea that space just ends out there somewhere is a bit of a fantasy. Nothing exists to suggest that, and all comparisons wind up being attempts to use experiences on Earth to relate to space which is just not possible given the magnitude of space itself.

Some people say that space is infinite. Well, infinite is a pretty big distance. I really don't know how big that is. But,
I can report that 40 Billion Light Years is a long, long, long way out there. As far as I can figure, from my own standpoint, that distance might as well be infinite.

Hope this helps you out.
Cheers,
Zah

Refer you to several good books on Astronomy for further details... Check your local library. Visit Space dot com.

Answer 9

I expect there is a lot we have no idea concerning its possible existence. Something that may be just as interesting would be to explore the different oceans and find there life forms we are yet ignorant of.

Answer 10

The way that i understand things is that when you reach the edge of the physical universe you will have reached the end of physical matter and with no frame of reference there can be no more distance.
