can you think that galaxy and other planetary systems are actually the atoms of thing from another world?

I asked my self the same question when I was 12 years old. I like to believe it. It was a nice idea; and then I imagine even bigger things (with the same concept) and smaller ones. But now I know it`s not possible (with the physics laws in our universe). For instance, you can not see nothing, since the diameter of the biggest atom is smaller than the lowest visible wave light. (that`s why we will never be able to see an atom, even with the best microscope ever)

That would be the Milky Way, the same galaxy that Earth and our solar system is in..

i also think aliens exist. out of all solar systems all the planets all the galaxies in the universe we can or should never argue that we are alone.

So far, we can only detect fairly large planets around nearby stars in our own galaxy.  However, the number of planets we are discovering shows us that planets are very common.  There is no reason to think that other galaxies would be any different.\n\nWe don't have sensitive enough tools yet to detect Earth-like planets, but they probably exist. We don't yet know how common life, intelligent or otherwise, is in the universe, but considering how many galaxies there are and how many stars in each one, it seems as though there should be other intelligent beings out there somewhere.

The Outer space does posses gases, but the vaccum is present because of the incomrehensible size of the universe. Had gases  such as Hydrogen and Helium not been present, there wouldn't have been a sun or nuclear fusion... vaccum indicates absence of matter. It becomes a matter of perspective whether you stand on earth and say that the galaxy andromeda is in outer space but earth is not.. when a hypothetical being on andromeda would say that earth is in outer space but andromeda is not... ;)

If you mean our Solar system (there's other suns with planets revolving around them) then our Solar System is in our Galaxy...The Milky Way.

Yes, it is entirely possible that there could be planets in other galaxies with life on them. There is nothing preventing the same conditions on our world being found on another world. It doesn't matter what people think about "aliens visiting our planet" or whether we can know about life out there. It definitely is possible.\n\nAs for the comment from Iamtheweasel: The bible doesn't say that you exist, but there you are! I don't mean to be rude, but does the Bible really have to say everything explicitly for it to be true, or even probable? It absolutely does not contradict that there is life on other worlds. From a fellow Christian, please don't be so closed-minded, especially by using a "No true Scotsman" fallacy of definition to define a Christian as one who doesn't think it's probable that there is life on other worlds.

At least 100 billion galaxies are known to exist in the Universe. Our galaxy is a spiral one, so in terms of structure it consists of galactic core and several spiral arms. In terms of composition it includes stars, planets (made from regular matter, including atoms of all naturally occurring elements and ions), galactic gas and dust (made from regular matter, mostly hydrogen and helium as far as the gas goes, and hydrogen, carbon, silicon, oxygen and some other elements as far as the dust goes), dark matter and dark energy (there is little known about the last two).

The matter that made up the sun and planets existed at one time as a very large disk. As the matter clumped together, it was already on the same plane. That's the theory, anyway.

Water is a necessity for life and that is based on temperature more so than which planet you are from the sun, it could be the tenth planet from the sun as long as the temperature is similar to ours here. \nBut with so many galaxies and suns in the universe I'm sure somewhere there is another world much like our own.\n\nHeres something you might like it shows everything that we are able to see in the universe and zooms down to our solar system.\n\nhttp://www.atlasoftheuniverse.com/universe.html

Yes, how could it be possible that we are the only planet that is positioned currently and close enough to a star in the entire universe?  Plus on a more spiritual aspect there is scripture upon the matter... "And by the word of my power, have I created them, which is mine Only Begotten Son, who is full of grace and truth.  And worlds without number have I created; and I also created them for mine own purpose; and by the Son I created them, which is mine Only Begotten."

The Earth is in the Solar system, the solar system is in the Galaxy and the galaxy is in the Universe AKA outer space. The answer to your question is not known, some say the Universe is the end of that line, stuff is made of atoms, atoms are made of protons, neutrons and electons, protons, neutrons and electrons are made of quarks, which are made of (I think) gluons, huons and mesons. I think that their is another universe, say a ten or eleven dimensional universe, that holds infinitely more four dimesional universes, like ours, this is part of string theory.

Well you can use spectroscopy to find out the composition of distant objects in space.  IE if a star emits light near (usually a slight red shift from distant objects) the emission lines of helium or mercury you could conclude that those elements are present.\n\nMike

Excluding any matter leaving the Earth (satellites) and entering the Earth (meteors), yes.  We are all the by-product of millions of years of evolution and environmental recycling, and could very well be sharing atoms with ancestral monkeys.

I go with the Big Bang theory and that our planet just happened to be in the right place at the right time. If our planet grew life then there is the possibility that other planets in other galaxies grew life as well. We just happened to get the right amount of heat and light from the sun.

i don't think in terms of the universe being massive compared to the size of galaxies,but minuscule compared to that which is outside the universe, that way there is an endless supply of material on hand.here at the"center of the universe"it's all relative to our thinking everything is so large but since all we can do is theorize about whats out there,why cant we theorize outside the box,way outside the box. where did science get this idea ? i believe that a chaotic set of galaxies brings about an ordered universe that is a single organism of a larger set of chaotic universes,which in turn forms ordered groups of galactic multiverses which is a small component of a megaverse ,and so on

Our solar system is not the only solar system in the universe.  There are hundreds and thousands and millions of other planets in the universe, and many are just like ours, but we don't know about them because we have never been able to get anything further than pluto to get a good specific picture of stuff.  In a general picture, though, we do know there are other galaxies in the universe
