outer space the nothing in between the something actually has different classifications interplanetary space this is the space within the confines of a solar system defined by the solar wind from the Sun but space reaches further Interstellar space this is the space in between solar systems Beyond reach of any bubbles of plasma being under the rign of only the black hole at the center of the Galaxy while that might sound Dreadful there's another terrifying classification of nothing inter Galactic space the space in between galaxies this is what makes up about 90% of the universe and the
interesting thing is this empty space seems to be inconsistent and fluctuant we can see this in instances like the bues void or more commonly known as the great nothing a spherical space spanning around 330 million Lighty years in diameter or 10 septian 526 sextilion 629 quintilian 999 quadrillion 999 trillion 999 9 bli 348 M 3106 bananas all lined up within the massive volume of the great nothing you could normally expect to see thousands of galaxies but the buz void only has about 60 to give you a better idea of how empty that really is we
discovered other galaxies the Adrina Galaxy in 1923 but if you were to place our galaxy The Milky Way into the middle of the bues Void we wouldn't have even known there were other galaxies in the universe until about the 1960s so why does this Gap in space exist to answer that question we must first have a surface understanding of the nature of the universe the universe is a sponge galaxies group into clusters the Milky Way for example is a part of the Virgo cluster but if you zoom out you'd see that even clusters form into
Super clusters our Virgo cluster being a part of the lakinia supercluster these super clusters have giant voids of their own but if we zoom out one one more time we see these massive voids in between superclusters the biggest being the buz void cool so why does the matter cluster up forming these huge voids the short confusing answer is that we think it's because of various fluctuations just after the big bang that have evolved and expanded over 13.8 billion years to leave a much lower density of materials than the areas around it blah blah blah long
answer is easier to understand but a little more complex let's go back to the Big Bang or more specific ly 10 to the- 32 seconds after the big bin at this point the visible universe is quite small and when I say quite small I mean incomprehensibly small at this scale you'd end up with Quantum fluctuations of SpaceTime which is a lot of words that I barely even know so let's break it down look at the air around you but zoom in really really close to the space in between the atoms you'll see energy spawning in
and out of existence randomly called Quantum fluctuations but they are are so small that they don't really do anything or affect anything but when the entire observable universe is that small you best believe that the random spawnings of energy is going to interfere with stuff you end up with interactions between really simple matter in the universe and light trapped in it being completely confined these interactions caused oscillations or in other words the universe was playing pong with photons and the universe continues to play Pong for about 380,000 years when the combination happens or basically the
kind of stuff becomes real stuff the universe forms its first atoms and because of this the light is not bouncing around in all that kind of stuff and is free to expand out indefinitely into the universe and so is everything else hence the ever expanding universe and we actually have a picture of that very moment called The Cosmic microwave background or in other words the fingerprint of the universe it's a picture of the microwave radiation that fills all of space in the observable universe notice how there's random fluctuations in radiation this is exactly what it
was like when things were first let loose and started to expand which is why everything is clumped up because it started that way from random Quantum fluctuation in the space in between is only getting bigger to the Unstoppable expansion of the universe look on the bright side there's a really big gap that's that's pretty cool
