There's a big dirty secret about black holes.

Contrary to widespread belief, the singularity of a black hole is not really at its center.

No, it's in the future of whatever crosses the horizon.

Black holes warp the universe so drastically that at the event horizon, space and time switch their roles.

Once you cross it, falling towards the center means going towards the future.

That's why you can't escape.

Stopping your fall and turning back would be just as impossible as stopping time and traveling to the past.

So the singularity is actually in your future, not in front of you.

And just like you can't see your own future, you won't see the singularity until you hit it.

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.

Singularities that are in the future are not a problem because we can't see them or interact with them.

But a naked singularity would be in front of us for all of us to see.

What would we see?

Well, the whole point is that it's impossible to know.

A singularity is a region of infinite gravity, and gravity is the bending of space-time.

At a singularity, the bending is so radical that the fabric of space-time is literally broken.

Space and time don't exist anymore.

This means that you can't predict anything, since predicting means making a forecast about where and when something will happen.

But where and when have lost their meaning.

So we have an unpredictable thing with infinite gravity and therefore infinite energy.

This means that anything could come out of it for no reason, from a pile of bananas to lost socks or a solar system.

Predictability, causality and physics as we know it would break down.

We think that singularities should exist in nature because we can prove

that under very general conditions gravitational collapse leads to the formation of singularities.

However, scientists think that nature forbids the formation of naked singularities.

Something enforces the creation of an event horizon around them to prevent their insanity from infecting the rest of the universe.

Without event horizons, physics may not make sense at all.

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.

So if we do destroy the horizon, we might destroy the fundamental rules of the universe.

You know what?

Let's not do that.

需要注意的發音

說話人用了 8 次縮略和弱讀形式，例如 can't, don't, won't。請按聽到的簡短形式來說。

長單詞——注意重音位置: singularity /ˌsɪŋɡjəˈlæɹətɪ/, causality /kɔˈzæl.ɪ.tɪ/, gravitational /ˌɡɹævɪˈteɪʃənəl/, predictability /pɹəˌdɪktəˈbɪlɪti/, insanity /ɪnˈsænɪti/

中文母語者容易讀錯的音：

詞尾子音 — 要讀清楚，後面不要加母音: predict /pɹɪˈdɪkt/, infect /ɪnˈfɛkt/, sock /sɑk/, warp /ˈwɔːp/, forbid /fɚˈbɪd/
/r/ 和 /l/ 的區別: singularity /ˌsɪŋɡjəˈlæɹətɪ/, gravitational /ˌɡɹævɪˈteɪʃənəl/, predictability /pɹəˌdɪktəˈbɪlɪti/
/æ/ — 嘴張大，不要讀成 /e/: singularity /ˌsɪŋɡjəˈlæɹətɪ/, causality /kɔˈzæl.ɪ.tɪ/, gravitational /ˌɡɹævɪˈteɪʃənəl/, insanity /ɪnˈsænɪti/, madness /ˈmæd.nəs/

如何用這段影片練習

先完整聽一遍影片，不要開口，記下不認識的單詞。
先用 0.75 倍速逐句跟讀，熟練之後再回到正常速度。
錄下自己的聲音並與原聲對比，特別注意 horizon, predict, causality 這類單詞。

什麼是跟讀法？

跟讀法 (Shadowing) 是一種有科學依據的語言學習技巧，最初開發用於專業口譯員的培訓，並由多語言者Alexander Arguelles博士普及。這個方法簡單而強大：您在聽英語母語原聲的同時立即大聲重複——就像是一個延遲1-2秒緊跟說話者的影子。與被動聽力或語法練習不同，跟讀法強迫您的大腦和口腔肌肉同時處理並模模擬實的講話模式。研究表明它能顯著提高發音準確性，語調，節奏，連讀，聽力理解和口語流利度——使其成為雅思口語備考和真實英語交流最有效的方法之一。
