Shadowing Practice: Why Earth Sucks Compared to the Planet Hestia - Learn English Speaking with Video

1
Our hottest update for Starbirds is out now.
2
Earth seems like a paradise for life, but it's actually kind of mid.
3
Big parts of it are covered by hostile deserts of ice, fire, rock or darkness.
4
Could there be a planet that's not just more suitable for life, but ideal?
5
So perfect for the emergence of life, filled with not just biomass, but also biodiversity, that Earth is a barren desert compared to them.
6
we've found a new and weird type of planet: Super Earths.
7
Planets larger than Earth that have the potential to not only host life, but to be super habitable.
8
Let's take all the science on exoplanets we have and imagine a perfect world: Hestia, after the Greek goddess of the Comfy Home,
9
the best possible planet for life in the universe.
10
First of all, we want a perfect star.
11
The perfect star for the perfect world.
12
The perfect world needs a perfect star, but that may not be a yellow dwarf like our Sun, because they die in under 10 billion years and keep getting hotter as they age.
13
70 % of the window for life on Earth has already passed.
14
Earth has a mere couple of billion years left before the Sun ends it all.
15
70 % of stars are red dwarfs.
16
Pretty small and alive for trillions of years, basically forever.
17
close to them, which makes it very likely that their planets are tidally locked, one hemisphere a hot desert and the other an icy hell.
18
Also, young red dwarfs tend to vomit deadly radiation that sterilizes their planets or boils their oceans away.
19
The perfect stars for life might be orange dwarfs.
20
In the Goldilocks zone between red and yellow dwarfs, their energy output is very stable, radiation tends to be less aggressive,
21
and most importantly, they live up to seven.
22
70 billion years, giving life plenty of time to emerge, evolve and thrive.
23
So here's our perfect star, an orange dwarf, born 3 billion years ago in a calm galactic neighborhood.
24
For the next tens of billions of years, it will be super stable.
25
Among dead rock planets and massive gas giants, one planet is our super habitable super earth,
26
Hestia, where life can thrive like nowhere else in the universe.
27
The perfect planet, a super habitable world.
28
Hestia's radius is 1 .3 times Earth's, so it has 70 % more surface area.
29
A lot more space for life.
30
With almost twice Earth's mass and 20 % more surface gravity, walking on it you'd feel 20 % heavier.
31
Unfortunately, it's a hot, dead desert.
32
Like Mars and Venus today, it's still missing two things.
33
Firstly, a magnetic field that protects Hestia from solar storms
34
and the cosmic radiation that sterilize its surface and blow its atmosphere away like poor Mars.
35
So, deep inside, Hestia gets a massive metallic core spinning in a liquid mantle
36
that creates a magnetic field of exactly the right strength for super strong protection.
37
And Hestia needs plate tectonics to mix its surface around.
38
because without tectonic plates breaking and mixing, the tension and heat below its surface unloads in apocalyptic volcanic eruptions.
39
Continental plates moving into the depths also remove CO2 from the surface, which is great because excess CO2 makes the atmosphere heat up too much.
40
And they bring up a vital mix of water, minerals and elements that life can feast on.
41
We also have something for you to feast on: our latest video game.
42
We've been working on this game together with the amazing birds over at Tucana Interactive for almost three years.
43
Starbirds is a relaxing factory building and resource management game in which you mine asteroids,
44
collect resources, craft goods, and create brain -twisting interstellar production networks.
45
scorching heat, and… wait… is that an alien tentacle?
46
Buh -ah.
47
Since we launched the game in Early Access last year, a lot has changed thanks to all the feedback we receive from those of you who've already played it.
48
We continued the story campaign and added two whole new star systems, introducing many more levels, production buildings, and alien life.
49
There's also a brand new free play mode
50
that lets you travel beyond the story campaign and generate your own levels
51
and we also added controller support if you'd rather play on the couch or on the go with your Steam Deck.
52
This is the second big update before we gear up for the grand finale.
53
We're looking forward to your feedback and experiences, and are now hard at work on the last big content update: the Starbirds full release.
54
Grab Starbirds for a special early bird discount on Steam now!
55
Okay, now that the basis for life is set, let's see how the surface turns out.
56
We still need to make a bunch of character choices to make Hestia super habitable.
57
Each upgrade comes with trade -offs life has to work with.
58
We want Hestia to have mild seasons that create migration, boom and bust cycles, and evolutionary pressure.
59
So we tilt its axis slightly and give it 36 -hour days, and four small moons that hang like pearls in the night sky.
60
the right resonance, they create stability, avoiding overly punishing disruptions.
61
The perfect land, wet, isolated, Warm.
62
Earth has one huge downside.
63
Most of its land is bound in large continents, whose central areas are very far away from water, creating deserts with scarce resources and hostile environments.
64
So for Hestia, we maximize coastlines and avoid megacontinents.
65
We'll give it many fragmented continental plates, creating a geology that's ideal for producing long island arcs.
66
of islands of all sizes and shapes.
67
All of its land has access to water, salt or fresh, without a single desert, creating the maximum land surface area for life.
68
Hestia's biomass on land is also supercharged because will make it 5 degrees Celsius warmer than Earth.
69
This doesn't sound like much, but as we know, Earth has plenty of spaces that are uncomfortably cold for much of the year, while tropical rainforests have ideal conditions for life.
70
On Earth, they hold more biomass than any other land ecosystem, and Hestia is nothing but tropical forests and ice -free polar regions.
71
thousands of little private niches to fill, each home to unique creatures that are ultra -specialized for it.
72
All possible variations on a theme manifest in different species, one stranger than the next. On Earth,
73
tropical forests like the ones in these islands house 50 % of all species on just 10 % of its land.
74
The isolated tropical islands have given nature thousands of attempts at building funny tree -type things that densely cover Hestia.
75
On Earth, plants are green to best catch energy from the sun, but with Hestia's orange dwarf, they take on darker shades to hoard the fainter light.
76
We could spend hours diving into cacti forest islands, where slow -moving hunter plants shoot poison needles at screeching feathered lemurs,
77
or the fungi forests of the high plateaus dominated by armored centipede lizards.
78
But we should move on to another ecosystem that Earth can only dream of the sky.
79
The best possible sky, another world to inhabit.
80
Hestia's large mass holds gases much firmer than Earth, so its atmosphere is much thicker, with just under one and a half times the pressure,
81
but much richer in oxygen and CO2.
82
This could be catastrophic for life, because high levels of oxygen make wildfires more likely and more devastating.
83
But since Hestia is so warm and humid, evaporation produces so much rain that wildfires never get powerful enough to wipe out problems.
84
The upsides are clearly worth it.
85
On Earth, the size of animals that breathe by diffusion is limited, which might be a good thing for us.
86
But on Hestia, all kinds of weird creatures can grow huge, like the four -legged insect megaphans, dominating the largest continent.
87
All that oxygen also lets animals have a faster metabolism and sustain higher activity levels.
88
Predators hunt more explosively, prey flees more dynamically, especially in a completely new dimension conquered by life.
89
up.
90
In Earth's thin atmosphere, flight costs a lot of energy, but in Hestia's super -dense air, it's super -cheap.
91
Despite the higher surface gravity, animals need much smaller wings and less energy to stay afloat.
92
Over billions of years, thousands of branches of Hestia's evolutionary tree have discovered flight
93
and the skies are full of flying animals of all sizes.
94
Like this sky whale shooting through the clouds, swallowing millions of tiny bird -like critters.
95
Enormous as they are, they never touch the ground except to lay eggs and when they die.
96
The thick atmosphere also does another thing really well: transfer sound.
97
Hestia is not a quiet place.
98
Anywhere you are, animals are communicating, warning each other, or screaming for mates.
99
This created super weird adaptations like hunters not trying to sneak up, but masking their direction of attack with disturbing and distracting noises.
100
system.
101
the best possible oceans, as many edges as possible.
102
Earth's oceans make up most of its surface and are on average 3 ,700 meters deep.
103
But sunlight can only reach 200 meters deep.
104
This sunlight zone is the only place plankton, the basis for the food web, can turn sunlight into sugar.
105
So it's where 90 % of marine species live.
106
95 % of the sea is in permanent darkness, much of it an abyssal desert.
107
So we don't want Hestia to have as much water as Earth. should be shallow.
108
Almost all of its oceans should be continental shelves 1 to 200 meters deep.
109
Virtually all of the ocean and its floor is a sunlight zone.
110
There are downsides to shallow oceans, of course.
111
They heat and cool faster, which creates stronger seasons and more storms.
112
But again, Disruptions drive life to specialize and make it more diverse.
113
Hestia's oceans house breathtakingly vast ecosystems.
114
Corals form living megacities stretching over thousands of kilometers, home to trillions of animals competing for real estate and forming complex relationships.
115
pseudo -crabs and fish lizards, and whatever this thing is supposed to be.
116
Bordering the megacities are kelp and algae colonies filled with life like tropical rainforests.
117
But there's another biodiversity supercharger Coastlines, where land and sea ecosystems meet,
118
nutrients mix, birds eat fish, and crocodiles hunt gorillas.
119
Even if they occupy only 7 % of the total marine area, they're home to more than half of marine life.
120
Hestia's coastlines are 45 times longer than Earth's, creating niches for dozens of millions of species.
121
A pretty mid -planet like Earth hosts some 9 million complex species.
122
Hestia with its huge surface area, super habitable conditions and sheer endless ecosystems could hold hundreds of millions.
123
What about intelligent life?
124
Well, our perfect planet has so many ecosystems and opportunities that it would probably develop sooner or later.
125
Maybe even multiple times at once.
126
Imagine a planet where different alien civilizations exist in parallel, each with their own empires of stone and wood, maybe metal and silicon.
127
How different would their perspective on living things and the nature of life be?
128
Would they try to eradicate each other, respect nature more or less, on a planet where any wound you cut would be filled up in no time?
129
What would they think of our desert planet with winters and ice? with a few specks of green.
130
Would they look at space and say: No thank you to planets that are so obviously inferior.
131
We don't know if a planet like Hestia exists, but it actually could.
132
Maybe among the quadrillions of planets in the universe, somewhere around a small and super -stable orange dwarf,
133
There's a place that's home to more life today than Earth has hosted in its entire history.
134
Here at Kurzgesagt, we know a thing or two about helping people learn.
135
For instance, for most of human history, the best way to learn something hard was to learn from someone who already knew it.
136
On a perfect planet, every student would have access to a great tutor, but that simply hasn't been possible.
137
Until now.
138
Meet the new Brilliant.
139

Wat is de Shadowing-techniek?
Shadowing is een wetenschappelijk onderbouwde taalleermethode die oorspronkelijk is ontwikkeld voor professionele tolkentraining en gepopulariseerd door polyglot Dr. Alexander Arguelles. De methode is eenvoudig maar krachtig: je luistert naar native Engelse audio en herhaalt het onmiddellijk hardop — als een schaduw die de spreker volgt met slechts 1–2 seconden vertraging. In tegenstelling tot passief luisteren of grammaticadrills, dwingt shadowing je hersenen en mondspieren om echte spraakpatronen tegelijkertijd te verwerken en te reproduceren. Onderzoek toont aan dat het de uitspraaknauwkeurigheid, intonatie, ritme, verbonden spraak, luisterbegrip en spreekvaardigheid aanzienlijk verbetert — waardoor het een van de meest effectieve methoden is voor IELTS Speaking-voorbereiding en echte Engelse communicatie.
