1
If you poured a giant bucket of water onto the sun,
2
would it actually extinguish it,
3
causing the Earth to become dark and frozen?
4
What water puts out normal fires because it cools the fuel and helps block oxygen.
5
But the sun isn't a normal fire.
6
It runs because hydrogen nuclei are smashing together in a powerful reaction called fusion.
7
So, if you flooded it with an enormous amount of water,
8
you'd be giving it more hydrogen to fuse.
9
And this amount of water would also increase the sun's mass,
10
causing Earth to be pulled in closer because of gravity.
11
Meaning, eventually, everyone on the planet would be cooked.
12
If you jumped out of a plane with a helium tank and a balloon,
13
could you fill it up on the way down and survive the fall?
14
Well, a single helium tank wouldn't have enough gas to slow you down.
15
Instead, you would need one bigger than yourself,
16
and your balloon would need to be over 16 feet wide.
17
But this would take way too long to inflate,
18
and since the weight of the tank would make you fall faster,
19
you'd only start floating once you dropped it.
20
This means you would need thousands of miles of fall time just to pull it all off.
21
But this is far beyond any plane's limit,
22
and at that height, you would actually just suffocate in space.
23
He was keeping score of the baseball game in 1902,
24
sitting next to two other guys.
25
Now, he was using a pencil to write down the information,
26
but after a while, it got too dull.
27
He knew Leroy had a small knife,
28
and asked if he could borrow it to sharpen his pencil.
29
He agreed, and as he pulled it out,
30
he opened it and began to hand it over.
31
But just as he did,
32
the player up to bat hit a foul ball that flew back towards the three men.
33
It struck the knife while it was still being passed over the man in the middle.
34
This forced the blade straight into his chest,
35
in between two ribs and just over his heart.
36
And within minutes, the 19-year-old bled to death.
37
right there on the spot.
38
Imagine you were picked up,
39
plopped into a glass coffin,
40
and forced to the bottom of the ocean.
41
You start freaking out because you have no idea why you're here.
42
And everything happens so fast that you don't know how deep you are.
43
As you feel around, you find a hammer.
44
Maybe it's to smash the coffin and escape?
45
But what if you're really deep and the coffin is pressurized?
46
This means smashing it could get you crushed instantly.
47
But you also could be shallow,
48
meaning you would just float up and survive.
49
The worst part is, you don't know how much oxygen you have left.
50
Could be an hour, could be minutes.
51
There's no timer, just your own panic making you breathe harder.
52
You grip the hammer just to hold something.
53
Maybe it's a dream, but the hammer feels real.
54
The cold sweat feels real.
55
You raise it up, take one final breath, and you swing.
56
Two mirrors were mounted to the rifle,
57
which allowed the image of the enemy to bounce from mirror to mirror and into the shooter's view.
58
Another stock was attached to a frame for stability.
59
Then they would pull on a cable that was attached to the trigger, eliminating the enemy.
60
You see, as soldiers popped out of trenches,
61
they would get shot almost instantly.
62
But this World War I device let them shoot without ever sticking their heads out.
63
Over time, the mirrors were swapped with cameras,
64
and they mounted a pistol on a hinge that could flip in either direction.
65
A screen on the back showed what the camera saw,
66
and the trigger cable was replaced with a second trigger on the grip,
67
neutralizing threats while keeping the shooter safe.
68
He was placed inside a plastic chamber just seconds after he was born,
69
and he lived this way for years,
70
unable to touch anyone or anything.
71
Even the air that went in had to be sterilized in a gas chamber.
72
You see, he was born with a rare disease that could kill him if a single germ got into his body.
73
When he was 12, doctors tried to cure him with a transplant of his sister's bone marrow,
74
and he was able to touch his family for the first time but the marrow contained an undetected virus.
75
And just weeks later, he tragically died.
76
His story has helped doctors spot the illness earlier in others,
77
which has ended up saving hundreds of lives.
78
The plane hit the tower,
79
and just an hour and 42 minutes later, it began to collapse.
80
Deep in the core, a small group of rescuers were carrying a woman down a stairwell as they felt the tower crumbling.
81
Now as each floor above them crashed into each other, everyone inside perished.
82
But the collapse actually didn't fall perfectly vertical.
83
The floors appear to have shifted unevenly,
84
tilting some of the weight outward and away from the center.
85
As they heard it crash down above them,
86
they knew they were doomed.
87
But the central position and the way the rubble fell somehow left a pocket of space protected.
88
A huge gust of wind pushed them down the stairs as the outer structure was stripped off
89
and the stairwell was literally exposed.
90
Everything else was obliterated, but part of stairwell B stood in the rubble and the 14 people inside survived.
91
The caper is placed inside an anchovy,
92
which is shoved inside an olive,
93
which is then stuffed into a tiny wild bird.
94
And that bird is stuffed into one that's slightly bigger,
95
which is shoved inside a third,
96
which is shoved inside a fourth,
97
and this is then stuffed into a quail,
98
meaning five birds in and it's still only the size of your hand.
99
But it keeps going, with each bird bigger than the last.
100
The gaps in between are filled with stuffing,
101
until finally the duck is shoved inside a chicken,
102
a pheasant, a goose and a turkey.
103
The last step is to shove it inside a bustard.
104
And the whole thing is cooked for 24 hours.
105
When it's done, it's sliced open to reveal all 20 layers.
106
But some of these birds are now illegal to eat.
107
So it's impossible to make this dish today.
108
They packed the tube with gunpowder,
109
drilled a hole for the fuse,
110
and secured the top with tape.
111
Then they loaded it with colored powder.
112
You see, the plan was to fire it,
113
and the color of the powder would reveal the gender of their baby.
114
But they decided to add extra gunpowder,
115
thinking it would make the reveal more impressive.
116
Now when they lit the fuse,
117
it ignited, but the force of the blast shattered the metal casing,
118
sending shrapnel flying through the air.
119
They all dove for cover,
120
but one piece of metal flew too fast and struck the grandma in the head.
121
Now they called 911, but it was too late.
122
By the time the powder cleared,
123
the only color left was red,
124
and she died without ever learning gender of her grandchild.
125
If you dropped the steak from really high up,
126
could the air resistance actually cook it,
127
leaving you with a perfectly seared filet?
128
Well, if you dropped it at the same height as the world record for skydiving,
129
the air up there is incredibly cold,
130
but the steak would be smashing into air molecules so fast
131
that the surface would get a tiny bit of heat from the shockwave.
132
the icy winds would still be freezing it over.
133
So when it finally lands,
134
you might have to thaw it out.
135
Now if we dropped it from 155 miles up,
136
the outside of the steak might get nicely seared,
137
but that heat only clings to the very surface.
138
The moment the steak drops lower,
139
it's slammed by icy cold air.
140
The inside never has time to warm,
141
so you would end up with a steak that's seared on the outside,
142
but still raw in the middle.
143
If we went even higher,
144
the air in front of the steak gets squashed so hard it would be thousands of degrees hot.
145
That heat burns the very outside layer until it flakes away in the wind.
146
Then the next layer is exposed.
147
And the same thing happens again and again,
148
like peeling layers off an onion,
149
which could leave you with a plate of char.
150
She dropped a potato into the first pot,
151
an egg in the second,
152
and coffee beans in the third.
153
Then she boiled them all for 20 minutes.
154
The potatoes started out hard,
155
but after being boiled, it's soft and limp.
156
The egg used to be delicate and fragile,
157
but boiling it has hardened it inside.
158
Now the coffee beans actually changed the water itself,
159
transforming it into something richer and different.
160
Each one faced the same adversity,
161
the boiling water, but each one responded differently.
162
One broke down, one toughened up,
163
and one completely transformed its environment.
164
So when the heat rises,
165
ask yourself, will you be the potato,
166
the egg, or the coffee beans?
167
If you swapped all the balls with human bodies on a Newton's Cradle,
168
would it still work?
169
Well normally this device works because the metal balls are so stiff.
170
So when one of them is hit,
171
it briefly squashes and then springs back,
172
sending that push all the way through to the last ball,
173
which flies out because it gets that shove.
174
But since human bodies are soft and squishy,
175
this energy gets absorbed more and doesn't transfer well.
176
The last person might swing out a bit,
177
but so would everyone else.
178
Even if you swung the first person as fast as possible,
179
the middle humans would just crumple,
180
getting bruised and squashed in the process.
181
Now the energy would make it to the last person,
182
but the bodies would be flung in the wrong directions.
183
Even if they were wearing some sort of metal armor,
184
and you swung it with a lot of force,
185
You might transfer enough energy for a few back and forth swings,
186
but you would still break some bones in the process.
187
A football player drove right into him, knocking him unconscious.
188
He eventually recovered and moved on.
189
And over the next 10 years,
190
he met his wife, had two kids,
191
and landed a dream job.
192
Life was normal for him.
193
Until one night, while sitting in his living room,
194
he noticed something odd about the lamp.
195
Now it still looked like a lamp,
196
but the perspective was off.
197
It was somehow distorted.
198
He was mesmerized by it, staying up all night.
199
He stopped eating and wouldn't leave the couch,
200
despite his wife begging him to.
201
She eventually took the kids and left.
202
And that's when reality hit him.
203
The lamp wasn't real.
204
His house, his wife and children,
205
none of it was real.
206
Suddenly everything collapsed inward, and he woke up on a sidewalk,
207
ten years younger, having just been knocked down by a football player.

シャドーイングとは？英語上達に効果的な理由
シャドーイング（Shadowing）は、もともとプロの通訳者養成プログラムで開発された言語学習法で、多言語習得者として知られるDr. Alexander Arguelles によって広く普及されました。方法はシンプルですが非常に効果的：ネイティブスピーカーの英語を聞きながら、1〜2秒の遅延で声に出してすぐに繰り返す——まるで「影（shadow）」のように話者を追いかけます。文法ドリルや受動的なリスニングと異なり、シャドーイングは脳と口の筋肉が同時にリアルタイムで英語を処理・再現することを強制します。研究により、発音精度、抑揚、リズム、連音、リスニング力、そして会話の流暢さが大幅に向上することが確認されています。IELTSスピーキング対策や自然な英語コミュニケーションを目指す方に特におすすめです。
