Shadowing Practice: Three Ways to Destroy the Universe - Learn English Speaking with Video
Les maken...
1
One day the universe will die.
2
But why? And how? And will the universe be dead forever?
3
And how do we know that?
4
First of all, the universe is expanding.
5
And not only that, the rate of its expansion is accelerating.
6
The reason: dark energy.
7
Dark energy is a strange phenomenon that scientists believe permeates the universe.
8
Until 1998 we thought that the universe must work a bit like a ball that you throw into the sky.
9
The ball moves up, but at some point it has to come down again.
10
But the expansion of the universe is actually speeding up.
11
That’s like throwing a ball up and watching it fly away faster and faster and faster.
12
Where is this acceleration coming from?
13
Well, we don’t know, but we call it “dark energy”.
14
Einstein thought of it first and then decided it was stupid.
15
Now, astrophysicists have decided it is plausible.
16
Trouble is, this is all very theoretical, and we don’t actually know what the properties of dark energy are.
17
But there are various theories and they lead us to three scenarios for the end of the universe.
18
One: the Big Rip.
19
Since its birth, the universe has been expanding.
20
For unknown reasons new spaces created everywhere equally.
21
The space between galaxies expands, so they move apart.
22
The space inside galaxies also expands, but here, gravity is strong enough to keep them together.
23
In the Big Rip scenario, the expansion accelerates up to a point where space expands so fast that gravity can’t compensate for this effect anymore.
24
The result is a Big Rip.
25
At first, only large structures like galaxies are torn apart, since space between the single objects expands very fast.
26
Next, big bodies like black holes, stars, and planets die.
27
Their gravity isn’t strong enough to keep them together, so they dissolve into their components.
28
In the end, space would expand faster than the speed of light.
29
Atoms would now be affected, and they would just disband.
30
Once space is expanding faster than light, no particle in the universe can interact with any other particle anymore.
31
The universe would dissolve into countless lonely particles that won’t be able to touch anything else in a strange, timeless universe.
32
Hmm, and you thought you felt lonely!
33
Two: Heat death or a Big Freeze.
34
In a nutshell, the difference between the Big Rip and heat death is that in a heat death scenario matter stays intact and is converted over an incredibly long but finite period of time into radiation, while the universe expands forever.
35
But how does this work? Let’s talk about entropy.
36
Every system tends towards the state of highest entropy, like when we have a latte macchiato.
37
Initially, it has different regions, but over time, they will cool down and disintegrate, until it’s uniform.
38
And this also applies to the universe.
39
So, while the universe gets bigger and bigger, matters slowly decays and spreads out.
40
At some point, after lots of generations of stars, all the gas clouds necessary to form stars will be exhausted, so the universe will turn dark.
41
The remaining suns will die; black holes will slowly degenerate and evaporate over trillions of years due to what’s known as Hawking radiation.
42
When this process is complete, only a dilute gas of photons and light particles remains, until even this decays.
43
All activity in the universe ceases at this point; entropy is at its maximum and the universe is dead forever.
44
Unless… theoretically, it might be possible that after an incredibly long amount of time, there might be a spontaneous entropy decrease as a result of something called “quantum tunneling”, leading to a new Big Bang.
45
Three: Big Crunch and Big Bounce.
46
This is the most uplifting scenario.
47
If there is less dark energy than we think or it decreases over time, gravity will be the dominating force in the universe one day.
48
In a few trillion years, the rate of expansion of the universe will slow down and stop.
49
After that, it reverses.
50
Galaxies will race at each other, merging as the universe becomes smaller and smaller.
51
Since a smaller universe also means a hotter universe, temperatures rise everywhere all at once.
52
One hundred thousand years before the Big Crunch, background radiation would be hotter than the surfaces of the most stars, which means that they would be cooked from the outside.
53
Minutes before the Big Crunch happens, atom cores are ripped apart, before supermassive black holes devour everything.
54
Finally, all black holes would emerge into a supermassive mega-black hole that contains the entire mass of the universe, and in the last moment before the Big Crunch it would devour the universe, including itself.
55
The Big Bounce theory states that this has happened a lot of times and that the universe goes through an infinite cycle of expansion and contraction.
56
Well, wouldn’t that be nice?
57
So what will actually happen to the universe in the end?
58
At the moment, heat death seems the most likely, but we at Kurzgesagt hope that this “dead forever” stuff is wrong and the universe will start over and over again.
59
We don't know for sure either way, so let’s just assume the most uplifting theory is true.
60
By the way, we have a Twitter account.

Uitspraak om op te letten
De spreker gebruikt 7 samentrekkingen en verkorte vormen, zoals don't, can't, isn't. Spreek ze kort uit, zoals je ze hoort.
- De klanken “sh” en “zh”: contraction /kənˈtɹækʃ(ə)n/, nutshell /ˈnʌt.ʃɛl/, acceleration /əkˌsɛl.əˈɹeɪ.ʃən/
- Lange woorden — let op de klemtoon: accelerate /ɪkˈsɛl.əˌɹeɪt/, astrophysicist /ˌæstɹəʊˈfɪzɪsɪst/, degenerate /dɪˈd͡ʒɛnəɹɪt/, disintegrate /dɪsˈɪntɪɡɹeɪt/, evaporate /ɪˈvæp.ə.ɹeɪt/
Klanken die Nederlandstaligen lastig vinden:
- Stemhebbende eindmedeklinker — /b/, /d/, /g/, /z/, /v/ niet verscherpen: dissolve /dɪˈzɑlv/, disband /dɪsˈbænd/, merge /mɝd͡ʒ/, emerge /ɪˈmɝd͡ʒ/
- /æ/ — opener dan de Nederlandse “e”: atom /ˈætəm/, astrophysicist /ˌæstɹəʊˈfɪzɪsɪst/, contraction /kənˈtɹækʃ(ə)n/, disband /dɪsˈbænd/, evaporate /ɪˈvæp.ə.ɹeɪt/
- /g/ — een harde plofklank, geen Nederlandse “g”: disintegrate /dɪsˈɪntɪɡɹeɪt/, exhaust /ɪɡˈzɔst/, mega /ˈmɛɡə/
Zo oefen je met deze video
- Luister de hele video één keer zonder te spreken en noteer de woorden die je niet kent.
- Spreek zin voor zin na op normale snelheid en herhaal elke zin tot je ritme gelijk is aan dat van de spreker.
- Neem jezelf op en vergelijk met het origineel; let daarbij op woorden als entropy, particle, devour.
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.
