isn't there always a "something" surrounding nothing? Billions of galaxies are in our Universe. What is beyond the universe? Nothing or something and if so what it that something and why is it outside?
The concept of nothing has always boggled the minds of people. What is "nothing"? The dictionary defines "nothing" as: not a thing; no thing. OK then, what's a"thing"? Again the dictionary defines "thing" as: an object or entity not precisely designated or capable of being designated. That seems rather straightforward - where there isn't "some thing" there is no thing, or, "nothing". Given that explanation, we could say that if we're looking at an object and our field of vision isn't blocked, then there is "nothing" between us and the object being viewed (along the exact line of sight). This has been the understanding of people since the beginning of time. The "ancients" looked up at the night sky and saw points of light in a vast emptiness - nothing. Even in the bible, the man Job states, "God stretches the northern sky over empty space and hangs the earth on nothing." (Job 26:7)
Over the years, we have learned a few things. We now know that if we're looking at an object and our field of vision isn't blocked, then there IS "something" between us and the object being viewed (along the exact line of sight) - gas (hydrogen, helium (water), nitrogen, etc.) However, since we can see through them (transparent), we've just assumed they weren't there. The same with the night sky. What we once thought was a vast empty void with numerous points of light, we now know is filled with numerous objects (meteors, comets, planets and galaxies), it's just our proximity to them that makes them "invisible". Then it goes the other direction. We are also surrounded by "things" that are so small that even though we are right next to them, our eyes can't detect them (molecules, atoms, protons, neutrons, electrons, leptons, quarks). Nothing just got a lot more crowded. As of now, we still see "nothing" between these small "things" and we classify it as "nothing". Yet who's to say there isn't actually something there? Just because we cant see something doesn't negate its existence.
One might say that this entire universe is a "container". It 'contains' all that's inside it (quarks to galaxies). It's also possible that this universe is also "contained" inside a larger "container" which is filled with other universes (multiverses?). It's also possible that this universe is all that there is and that outside of it - isn't. Or, perhaps there is what many don't want to admit - God. "By faith we understand that the entire universe was formed at God’s command, that what we now see did not come from anything that can be seen" (Hebrews 11:3)
