1
The vast majority of the cosmos is voids.
2
Gigantic, unfathomably large  spaces of empty nothingness.
3
Bubbles of eternal night, stretching  hundreds of millions of light-years, almost entirely devoid of  galaxies, stars, or light.
4
The loneliest places in existence.
5
Voids are not just the absence of stuff but  weird worlds of darkness that are growing, drifting, colliding and merging with  each other – Inside them space itself is stretched violently and it's  almost impossible to enter them.
6
Simply put: voids are weird and scary.
7
But they sculpt the entire universe  and may ultimately decide its fate.
8
Today we know of over 8,000 voids and  supervoids, and we keep discovering more.
9
No matter how large a cluster or  supercluster of galaxies gets, there always seems to be  an even larger void nearby.
10
Let’s jump off the cosmic cliff and drop  into the heart of cosmic nothingness.
11
The Loneliest Place in the Universe You are zooming away from Earth, at  thousands of times the speed of light, leaving our solar system and  our solar neighborhood behind.
12
Now we see the entire Milky Way  with its 200 billion stars and dozens of dwarf galaxies zipping around it.
13
2.5 million light-years away on a collision course is giant Andromeda and its own  swarm of satellite galaxies.
14
We are now moving a million times faster than the  speed of light, seeing the local group of over 50 galaxies woven together by gravity, rivers of  gas, and invisible scaffolds of dark matter.
15
This is our pocket of the universe, 10 million  light years across, no human will ever leave it.
16
Except for you apparently.
17
As we zoom away even faster  we see the Virgo Supercluster, a colossal wall of more than 2,000 galaxies  spread over roughly 100 million light-years.
18
Careful now, you are right on the edge  of the cosmic cliff where the true, deep darkness begins: the Local Void – a gigantic,  empty bubble 200 million light-years across.
19
If it was a bright thing  and not absolute darkness, it would fill 40% of the  night sky we see from earth.
20
All around us are dozens of other superclusters and gigantic voids filled  with suffocating emptiness.
21
You are now traveling towards the greatest and emptiest nothing in existence – right  into the center of the Boötes Supervoid.
22
A cosmic desert around 300  million light-years wide.
23
So gigantic it should contain  thousands of galaxies.
24
But instead, what do you see?
25
You are surrounded by perfect darkness, the most  absolute blackness the human mind can conceive.
26
There is no up or down.
27
No motion. Nothing to orient yourself.
28
There is not a single sign that  the outside universe even exists.
29
It’s an inescapable prison.
30
And this isn’t some exotic corner of the cosmos.
31
This is how the vast majority of  the universe feels to human eyes.
32
Just silent blackness without any movement.
33
Everywhere.
34
Forever. Although there is something mysterious hiding  in the dark – faint tendrils of dark matter, penetrating into the void like cosmic lichen.
35
A miniature echo of the much larger  forest of dark matter filaments that forms the scaffold of galaxies and  galaxy clusters outside the void.
36
And at their tips we find faint  blueish specs in the ocean of darkness: Void galaxies, lonely fireflies  unable to light up the night.
37
The rarest galaxies we know,  very isolated, very lonely.
38
A Universe of Bubbles Before we could look deep into space, astronomers thought we lived in a uniform  cosmos with galaxies spread out evenly.
39
But instead, we found that galaxies, cosmic gas and dark matter were  arranged into a vast cosmic web.
40
A recurring pattern of sheets and filaments,  organized around enormous empty gaps, meeting at dense knots with galaxy  clusters and super clusters.
41
But this structure is not static, it just seems to be because the distances  between galaxies are so incredibly vast.
42
In reality galaxies shoot through space at  speeds of millions of kilometers per hour.
43
They are on collision  courses, orbiting each other, moving towards the center of larger galaxy  clusters millions of light years away.
44
But they always seem to stick to the rims of voids like reflections of light on soap  bubbles – which is kind of weird.
45
If they are this dynamic, shouldn’t a  galaxy shoot into a void occasionally?
46
Well voids are actually extremely hard to  enter for galaxies from the outside – at least naturally – because gravity becomes weird at  their edges and even weirder deeper inside them.
47
If you didn't know better, you might  think voids spit out anything trying to get inside, pushing galaxies to the edge.
48
The way gravity works is that everything with mass in the universe attracts  every other thing with mass.
49
And since there is almost no mass inside, the cosmic web of galaxy super clusters on  their edges are pulling things out of voids.
50
The emptier a void is, the harder  gravity is pulling on what remains.
51
It's really like a tug of war  where one side isn’t even trying.
52
Over time voids are really only  getting even emptier and the walls and knots around them denser and brighter.
53
Would it be hard to fly into a cosmic void  with a spaceship? Well not technically, the hardest part is escaping  the gravity of your home galaxy.
54
It also doesn’t make much sense  because… what exactly do you want to visit inside a void? It makes sense  to fly into a void if you want to hide.
55
Like really, really hide.
56
But what cosmic horror would be scary enough for a  civilization to try to escape into a cosmic void?
57
Galaxies in the crowded cluster regions  like our milky way are very active, since its neighbours’ gravity tugs and  pulls at it, they collide and merge.
58
Void galaxies are so isolated that  they are aging in slow motion.
59
They tend to be smaller, bluer and full of  gas, birthing new stars slower and calmer.
60
So void galaxies could be the last places that  will stay habitable in our dying universe.
61
The last star in the universe  will likely be born here.
62
So maybe in a 100 trillion years or so  a desperate alien race will embark on an impossible journey to stretch their existence  just a bit longer inside a void galaxy.
63
There is one more thing that makes  voids unique places: Dark Energy.
64
The mysterious force that most  scientists think is accelerating the expansion of the universe and  will ultimately cause its demise.
65
We can’t see dark energy do anything inside our  galaxy or inside clusters because there is too much stuff pulling things together via gravity  – but we can see its effects inside voids.
66
Here dark energy blows up the bubbles of nothing.
67
This is where the acceleration of  cosmic expansion becomes visible.
68
As voids are getting larger and larger, they  are breaking the structure of the universe, the beautiful galaxy filaments  are slowly being ripped apart.
69
As the emptiness encroaches, walls of  thousands of galaxies are thinned out and pulled towards the edges – attracted  by much denser regions at the margins, giving space to the emptiness of  two void bubbles becoming one.
70
In the far, far future supervoids will  take over the observable universe.
71
Crushing clusters, and expanding further  and further, until the entire observable universe is nothing more than  a gigantic void of nothingness.
72
The loneliest place in existence.
73
Let’s head back to Earth.
74
When we land, please exit through the  gift shop and pick up a few souvenirs.
75
We created this latest Space Souvenir  Drop for all of you who have been travelling with us for so many years now. While you’re there, take a look around, you might discover a unique product  dedicated to your favorite science topic.

쉐도잉이란? 영어 실력을 빠르게 키우는 과학적 방법

쉐도잉(Shadowing)은 원래 전문 통역사 훈련을 위해 개발된 언어 학습 기법으로, 다언어 학자인 Dr. Alexander Arguelles에 의해 대중화된 방법입니다. 핵심 원리는 간단하지만 매우 강력합니다: 원어민의 영어를 들으면서 1~2초의 짧은 지연으로 즉시 소리 내어 따라 말하는 것——마치 '그림자(shadow)'처럼 화자를 따라가는 것입니다. 문법 공부나 수동적인 청취와 달리, 쉐도잉은 뇌와 입 근육이 동시에 실시간으로 영어를 처리하고 재현하도록 훈련합니다. 연구에 따르면 이 방법은 발음 정확도, 억양, 리듬, 연음, 청취력, 말하기 유창성을 크게 향상시킵니다. IELTS 스피킹 준비와 자연스러운 영어 소통을 원하는 분들에게 특히 효과적입니다.
