Witnesses say that an Everest sized asteroid hit Earth, devastated the planet and caused a mass extinction.

目擊者說，一顆聖母峰大小的小行星撞擊地球，摧毀了這顆行星並造成了大滅絕。

A simple, fascinating and convincing explanation.

一個簡單、迷人又令人信服的解釋。

In the last few years, new evidence has reinvigorated an older theory pointing at a second suspect.

在過去幾年裡，新證據重新激發了一個較早的理論，指向了第二個嫌疑犯。

A very slow and liquid asteroid, 1,000 times bigger, hitting Earth on the opposite side of the planet.

一顆非常緩慢且液態的小行星，大一千倍，撞擊了地球的另一側。

就像我們這個真實犯罪頻道一樣。

Let's look at the new evidence and tell a different story that could change everything we thought we knew.

讓我們來看看新證據，講述一個可能改變我們所有認知的不同故事。

66 million years ago, Earth was barely recognizable.

六千六百萬年前，地球幾乎認不出來。

One of the hottest periods in Earth's history.

Humid, lush jungles and woodlands covered much of the planet.

濕潤茂密的叢林和林地覆蓋了大部分的行星。

Even the polar regions were home to forests of precious prehistoric pines and ferns.

即使是極地區域，也曾是珍貴史前松樹和蕨類植物的森林。

Amazing ecosystems that were robust enough to survive the many months of darkness during the polar night.

令人驚嘆的生態系統，足以度過極夜的漫長黑暗。

Marine lizards and long necked monsters up to 15 meters swam in the oceans.

海洋蜥蜴和長頸怪物，長達15公尺，在海洋中游動。

And on land, Basically everything larger than 1 meter was a dinosaur.

在陸地上，基本上所有超過1公尺的生物都是恐龍。

One of the most successful animals ever to walk Earth.

Dominating the world for more than 150 million years.

All these majestic creatures vanished in a split second of geological time.

這些雄偉的生物在地理時間的瞬間消失了。

Yes, it is true that around that time a big asteroid hit Earth.

是的，確實在那段時間，一顆巨大的小行星撞擊了地球。

But was this actually what killed the dinosaurs?

但這真的是殺死恐龍的原因嗎？

Or did it arrive just in time to get all the blame?

還是牠只是剛好出現，背負了所有的罪名？

Because according to some recent science, just before the asteroid struck, an ancient nightmare, older than even the dinosaurs, decided to destroy the world.

因為根據一些最新的科學研究，就在小行星撞擊地球之前，一個比恐龍還要古老的夢魘，決定要摧毀世界。

讓我們來看看牠是怎麼做到的。

The ancient continents almost resembled the world of today, but not quite.

遠古的大陸幾乎跟現在的世界差不多，但又不完全一樣。

India was still a continent sized tropical island full of lush rainforests and exotic life on its way to smash into Asia.

印度當時還是一個大陸大小的熱帶島嶼，充滿了茂密的雨林和奇異的生物，正準備撞上亞洲。

But this paradise also hosted something else.

但這個天堂也孕育了別的東西。

A volcanic region a thousand kilometers wide and about to come to life in a dramatic fashion.

一個寬一千公里的火山區，即將以戲劇性的方式爆發。

The apocalypse began quietly and silently.

About 800,000 years before the impact, the Deccan Traps began to exhale about 10 million tons of CO2 and sulfur dioxide each year.

大約在撞擊前八十萬年，德干暗色巖開始每年噴發約一千萬噸的二氧化碳和二氧化硫。

Which in the grand scheme of things was not that much.

但從宏觀來看，這其實不算太多。

所以很長一段時間，沒有人注意到。

The problem was these emissions wouldn't stop for half a million years.

問題是這些排放量持續了五十萬年都沒有停止。

They started to dangerously pile up in the atmosphere.

它們開始危險地堆積在大氣中。

About 300,000 years before the asteroid, the Deccan Traps started to vomit lava.

大約在小行星撞擊地球前三十萬年，德干暗色巖開始噴發巖漿。

這跟一般的火山爆發完全不一樣。

Imagine a landscape with volcanoes stretching beyond the horizon.

想像一下，火山綿延至地平線的景象。

They were constantly active, releasing a steady flow of massive amounts of poison and lava, interrupted by much more violent and deadly eruptions.

它們持續活躍，釋放出源源不絕的大量毒素和巖漿，偶爾還伴隨著更劇烈、致命的爆發。

The lush paradise of India was the first victim, as gigantic clouds spread toxic fumes and poisoned the coastal regions.

印度的這片豐饒天堂成了第一個受害者，巨大的雲團散播毒氣，毒害了沿海地區。

Clouds of ash darkened the sky as rivers of magma started massive wildfires, eradicating many local ecosystems and paving the continent with dead dinosaurs.

灰燼雲遮蔽了天空，巖漿洪流引發了大規模的野火，摧毀了許多當地生態系統，並讓這片大陸佈滿了死去的恐龍。

Still, at this point, it all looked like a local catastrophe, one of many that have hit our planet over its billions of years of history.

不過，到這個階段，這一切看起來都只是一場地方性的災難，就像我們的地球在數十億年的歷史中經歷過的許多災難一樣。

Had it stopped here, there might still be dinosaurs today.

如果就這樣結束，恐龍可能到今天都還存在。

The Deccan Traps would just not stop spewing lava.

德干暗色巖就是不停地噴發巖漿。

And so, after hundreds of thousands of years of never ending volcanic emissions, the catastrophe became global.

於是，在數十萬年不間斷的火山排放後，這場災難演變成全球性的。

First, the planet experienced a wave of heating, with oceans getting at least 2 degrees Celsius hotter in just 100,000 years.

首先，地球經歷了一波加熱，海洋在短短十萬年內就變熱了至少攝氏兩度。

Which is bad, but just about the time frame that leaves ecosystems a chance to adapt.

這很糟糕，但大致還在生態系統有機會適應的時間範圍內。

But then nature would pull a cruel prank.

但接著，大自然卻開了一個殘酷的玩笑。

Some of the gases of the Deccan Traps heated the planet up, while others cooled it down.

德干暗色巖中的某些氣體讓地球暖化，而另一些則讓它冷卻。

So after the initial warming, a period of cooling followed, massively stressing the ecosystems that barely managed to adapt to the hotter temperatures.

所以在最初的暖化之後，緊接著是一段冷卻期，這對好不容易適應了較高溫度的生態系統造成了巨大的壓力。

At the same time, the sulfur in the atmosphere came back down as acid rain, while the CO2 was acidifying the oceans and killing the plankton, which was, and

同時，大氣中的硫磺以酸雨的形式降下，而二氧化碳則使海洋酸化並殺死了浮游生物，而浮游生物過去，

still is today, the basis of the food web in the oceans.

And if plankton disappears, a massive extinction is all but guaranteed.

如果浮游生物消失了，大滅絕幾乎是不可避免的。

But now, the grand finale was about to begin.

About 50,000 years before impact, the true apocalypse came like a cosmic horror.

在撞擊前約五萬年前，真正的末日如宇宙般的恐怖降臨。

Breaking out of its prison, the Deccan Traps roared and screamed and began to spew out tens of trillions of tons of magma and even more deadly gases in an onslaught that lasted for several thousand years, rolling over ecosystems, devastating everything they reached.

德干暗色巖掙脫束縛，咆哮嘶吼，開始噴出數十兆噸的巖漿，甚至更多致命的氣體，這場持續數千年的猛攻席捲了生態系統，摧毀了它們所觸及的一切。

For a time as long as all of human civilization, this lava Armageddon brought massive wildfires.

在長達整個人類文明的時間裡，這場巖漿末日引發了大規模的野火。

Earthquakes and tsunamis smashed and shook the continent.

地震和海嘯猛烈搖撼了這片大陸。

So much heat was released from the roaring hot interior of our planet that it might have created hypercanes, cyclones tens of kilometers wide, with winds reaching almost 1,000 kilometers an hour, three times more than the deadliest hurricane ever recorded by humanity.

我們星球熾熱的內部咆哮著釋放出驚人的熱量，可能引發了超級颶風，這種寬達數十公里的氣旋，風速接近每小時一千公里，比人類記錄過最致命的颶風強上三倍。

These storms were so massive and intense that they could reach tens of kilometers into the stratosphere and rip holes into the ozone layer, with devastating consequences for all life.

這些風暴規模巨大且強度驚人，它們能深入平流層數十公里，撕裂臭氧層，對所有生命造成毀滅性的後果。

Now, without protection from the sun's radiation, and

現在，在沒有太陽輻射保護的情況下，

of course, where the hyperstorms occurred, devastation and death would follow.

當然，在超級風暴發生的地點，毀滅和死亡隨之而來。

Out of the guts of the Earth came colossal amounts of venom.

Giant clouds loaded with mercury and hydrochloric acid rolled over the planet, delivering the final blow to the remnants of a once magnificent and fertile world.

充滿汞和鹽酸的巨大雲團席捲了整個星球，給這個曾經輝煌肥沃的世界的殘餘物致命一擊。

As food chains crumbled and the whole world around them collapsed, some of the last dinosaurs to ever walk the Earth may have died, vomiting toxic foam while being bathed in acid rain.

隨著食物鏈崩潰，他們周遭的世界也隨之瓦解，一些最後漫步在地球上的恐龍，可能就在酸雨沐浴下，嘔吐著有毒保麗龍而死去。

A cruel end for the members of a noble family that had ruled the world for so long.

對一個統治世界如此之久的尊貴家族成員來說，這真是殘酷的結局。

The frenetic eruptions slowed down and the endless natural disasters began to fade away.

劇烈的噴發減緩，無止盡的天然災害也開始消退。

The monster had left unfathomable devastation and corpses in its wake.

這個怪物留下了難以想像的毀滅和屍體。

Even the planet's ecosystems far away were severely wounded.

就連行星遙遠的生態系統也遭受了嚴重的創傷。

It was the end of a whole geological era.

A murder that started slowly and then turned loud and violent.

一場緩慢開始，然後變得喧鬧而暴力的謀殺。

Like a cosmic joke on the other side of the world.

A bright dot of light appeared in the sky, and

天空中出現了一個明亮的光點，

an instant later, an asteroid 10 kilometers across smashed into Earth with the power of 4 billion atomic bombs.

一瞬間，一顆直徑十公里的巨大行星撞擊地球，威力相當於四十億顆原子彈。

If you want to see what this was like, we made a whole video about it.

如果你想看看當時是什麼情況，我們做了一整支影片來介紹。

If life on Earth was like a murder victim, barely holding on, this was the final blow.

如果地球上的生命就像一個瀕臨死亡的謀殺案受害者，那麼這就是最後一擊。

After the massacre on the other side of the world, the Deccan traps went on, expelling tens of trillions of tons of deadly gases for another 800,000 years, making sure the devastated planet stayed covered in poison.

在地球另一側發生大屠殺後，德干暗色巖又持續噴發了八十萬年，排出數十兆噸的致命氣體，確保這顆被摧毀的行星持續籠罩在毒氣之中。

When they eventually finished and truly went back to sleep, 75% of all species on Earth had perished.

當它們終於停止噴發並真正沉寂下來時，地球上百分之七十五的物種都已滅絕。

最為人熟知的，是幾乎所有的恐龍。

Except birds, the only dinos that are still with us today.

除了鳥類，牠們是我們今天仍然看得到的唯一恐龍。

Their stunning beauty and diversity are a shy reminder of how majestic and wonderful their larger cousins must have been.

牠們令人驚豔的美麗與多樣性，含蓄地提醒著我們，牠們那些體型龐大的表親曾經是多麼雄偉與奇妙。
