1
- In the early hours of Sunday, September 14th, 2015, a scientist in Louisiana makes a fateful decision.
2
- Robert Schofield has been working all weekend doing final calibrations.
3
- All righty, let's take a spectrum.
4
- He has one last test, - So let's see where this computer's getting its power.
5
- But it's late, and the equipment is not cooperating.
6
- It was about four or so in the morning, and we still had about another hour of work to do.
7
And we were like, "Yeah, things aren't working so well and I'm really tired.
8
Let's not do this last hour or so of work." - They call it a night.
9
And 40 minutes later, in the silence of their inactivity, they open the door to history.
10
A powerful gravitational wave rumbles through both detectors, Louisiana and Washington.
11
Had Robert Schofield worked 40 more minutes that night with the instruments in test mode, a signal that had been on its way for 1.3 billion years would never have been recorded.
12
- I like to say, you know, one of my biggest contributions to LIGO has been my laziness that day.
13
- I got an email from somebody here saying, "Hey, look at this place on the web." I looked at that and I said, "Holy (beep)." - It was so strong that you could see it by eye in the data.
14
It was too good to be true.
15
- But it was true.
16
In fact, it was loud and surprisingly clear.
17
- And it just sang at you.
18
Just there it was, standing out.
19
- The signal lasted less than a second.
20
But in that briefest of moments, it delivered a cosmically profound message more than a billion years in the making, proving the existence of black holes.
21
- So what we saw in the signal involved oscillations of the mirrors that were slow at first, became faster and faster and faster.
22
And this was precisely the kind of behavior that you would expect from gravitational waves caused by two black holes going around each other, spiraling together.
23
- Two massive black holes, one 29 times the mass of the Sun, the other 36 times the mass of the Sun, whipping around each other hundreds of times a second, finally completing their act of mutual destruction by merging, creating a single larger black hole of 62 solar masses.
24
The violent merger converts some of the mass into an apocalyptic release of energy beyond anything ever before witnessed.
25
- The collision, in effect, creates a veritable storm in the fabric or the shape of space and time.
26
As though you had taken three suns, you had annihilated them completely, converted it in to gravitational waves.
27
The power was 50 times higher than the output power of all the stars in the universe put together, in a fraction of a second.
28
But the most powerful explosion that humans have ever had any evidence for, with the exception of the Big Bang.
29
- Since that very first signal in September, 2015, LIGO has detected several more collisions of black holes.
30
In October, 2017, Ray Weiss, Kip Thorne, and LIGO's former director, Barry Barish, received the Nobel Prize.
31
The LIGO discoveries proved that black holes can merge, one way they can grow bigger quickly.
32
- More and more evidence of these merging black holes tells us there are a lot of these stellar black holes around that they can find each other and merge.
33
- And the discovery opened an entirely new way of observing the universe.
34
- We always thought of astronomy as an observational field where we are looking at radiation, we are seeing things.
35
But this is not radiation, this is something much more fundamental.
36
These are sort of fundamental tremors in space time itself.
37
We can now hear the universe.
38
- For the first time, astronomers have simultaneously seen and heard a cosmic event.
39
In August, 2017, LIGO detected gravitational waves from a collision of two neutron stars.
40
Black holes are empty space, but neutron stars are dense dead stars that can crash together and light up the skies.
41
When telescopes and satellites around the globe pointed in the direction of the sound, the world saw fireworks in an explosive collision and afterglow.
42
Possibly the collision resulted in the creation of a new black hole.
43
But unless we observe the formation of a black hole, there is much we will never know.
44
Because so much about black holes is irretrievably out of our reach, we can never know where they came from, what's inside, or their history.
45
But we can imagine their future.
46
The number of black holes in the universe is increasing, and they're getting bigger.
47
Stars collapse, black holes feed and merge, new ones form.
48
Could it be that one day everything will end up inside them and they will rule the universe?
49
Untold trillions upon trillions of years after this happens and the last bits of matter cross their event horizons, black holes themselves may radiate away and vanish from this reality.
50
Their mysteries are many, and we're just starting to unlock the secrets of these strange, powerful places.
51
But one thing is certain, black holes will continue to intrigue us, tantalize us, and challenge both our science and our imaginations.

이 수업에 대하여

이 수업에서는 2015년에 발생한 중력파의 첫 발견에 대한 이야기를 통해 영어 실력을 향상시킬 것입니다. 수업을 통해 우주, 블랙홀, 그리고 과학적 발견에 관한 중요한 내용을 학습하며, 반복 연습을 통해 영어 발음과 표현을 교정할 수 있습니다. 유튜브 영어 공부를 통해 자연스러운 대화 기술을 익히고, 그 과정에서 shadow speech 기법을 활용하여 효과적으로 말하기 능력을 키워보세요.

주요 어휘 및 구문

  • 중력파 (gravitational wave) - 우주에서 발생하는 중력의 파동.
  • 블랙홀 (black hole) - 중력이 매우 강해 빛조차 빠져나올 수 없는 천체.
  • 병합 (merging) - 두 개의 물체가 하나로 합쳐지는 과정.
  • 중성자별 (neutron star) - 고밀도의 별 형태, 블랙홀로 변할 수 있음.
  • 사건의 지평선 (event horizon) - 블랙홀이 빛과 물질을 영원히 가두는 경계.
  • 우주 (universe) - 모든 우주적 존재와 현상이 포함된 개념.
  • 관측 (observation) - 과학적 연구를 위해 현상이나 데이터를 주의 깊게 살펴보는 것.
  • 발견 (discovery) - 새로운 정보나 사실을 찾아내는 과정.

연습 팁

프레젠테이션을 들으며 shadow speak 기법을 활용해보세요. 처음에는 느린 속도로 따라 해보며 발음과 억양에 집중하세요. 그런 다음 점차 원래의 속도에 맞춰 연습하면서 영어 발음을 교정하세요. 이 영상의 톤은 실험적인 발견의 흥미로움을 담고 있으므로, 감정을 담아 읽는 것이 중요합니다. 최소한 3~5번 반복해서 연습하면 IELTS 스피킹의 자연스러운 대화 기술을 향상시킬 수 있습니다. 이러한 연습을 꾸준히 하다 보면, 영어 대화에서 블랙홀과 같은 다양한 주제를 자유롭게 다룰 수 있게 될 것입니다.

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.
