Shadowing Practice: How to Destroy a Black Hole - Learn English Speaking with Video
Creando lección...
1
There's a big dirty secret about black holes.
2
Contrary to widespread belief, the singularity of a black hole is not really at its center.
3
No, it's in the future of whatever crosses the horizon.
4
Black holes warp the universe so drastically that at the event horizon, space and time switch their roles.
5
Once you cross it, falling towards the center means going towards the future.
6
That's why you can't escape.
7
Stopping your fall and turning back would be just as impossible as stopping time and traveling to the past.
8
So the singularity is actually in your future, not in front of you.
9
And just like you can't see your own future, you won't see the singularity until you hit it.
10
But you also can't hit something that's in your future, only sort of experience it, like you'll experience your next birthday when it happens.
11
Singularities that are in the future are not a problem because we can't see them or interact with them.
12
But a naked singularity would be in front of us for all of us to see.
13
What would we see?
14
Well, the whole point is that it's impossible to know.
15
A singularity is a region of infinite gravity, and gravity is the bending of space-time.
16
At a singularity, the bending is so radical that the fabric of space-time is literally broken.
17
Space and time don't exist anymore.
18
This means that you can't predict anything, since predicting means making a forecast about where and when something will happen.
19
But where and when have lost their meaning.
20
So we have an unpredictable thing with infinite gravity and therefore infinite energy.
21
This means that anything could come out of it for no reason, from a pile of bananas to lost socks or a solar system.
22
Predictability, causality and physics as we know it would break down.
23
We think that singularities should exist in nature because we can prove
24
that under very general conditions gravitational collapse leads to the formation of singularities.
25
However, scientists think that nature forbids the formation of naked singularities.
26
Something enforces the creation of an event horizon around them to prevent their insanity from infecting the rest of the universe.
27
Without event horizons, physics may not make sense at all.
28
So although black holes have been portrayed as the ultimate monsters of the universe, they may actually be the heroes that keep us safe from the madness of singularities.
29
So if we do destroy the horizon, we might destroy the fundamental rules of the universe.

Let's not do that.

¿Qué es la Técnica de Shadowing?
Shadowing es una técnica de aprendizaje de idiomas respaldada por la ciencia, desarrollada originalmente para la formación de intérpretes profesionales y popularizada por el políglota Dr. Alexander Arguelles. El método es simple pero poderoso: escuchas audio en inglés nativo y lo repites en voz alta de inmediato, como una sombra que sigue al hablante con solo 1-2 segundos de retraso. A diferencia de la escucha pasiva o los ejercicios de gramática, el shadowing obliga a tu cerebro y músculos de la boca a procesar y reproducir simultáneamente patrones de habla reales. Las investigaciones muestran que mejora significativamente la precisión de la pronunciación, la entonación, el ritmo, el habla conectada, la comprensión auditiva y la fluidez al hablar, convirtiéndola en una de las metodologías más efectivas para la preparación del IELTS Speaking y la comunicación en inglés en el mundo real.
