What's the next step? How do we get through this?" [explosion booms] - The destruction never stops. The chaos never stops. [explosion booms] It just keeps going until everything is ripped apart and torn asunder. [explosion booming, screaming] <i>[bell tolls]</i> <i>narrator: In New Mexico's high desert,</i> <i>the radio telescope observatory,</i> <i>known as the Very Large Array,</i> <i>scans the skies above.</i> <i>Scientists are tracking something truly horrifying</i> <i>barreling towards Earth.</i> - The first thing you do when you see a new phenomenon is you use computers to simulate what happens into the future. <i>And as we run the videotape forward,</i> <i>we begin to say to ourselves,</i> <i>"Oh, my God!"</i> <i>- It's a black hole.</i> A supermassive black hole with a billion times the mass of the sun. <i>narrator: Of all the objects in space,</i> <i>this lethal mass possesses</i> <i>the strongest gravitational pull,</i> <i>earning its name.</i> <i>Because nothing, not even light,</i> <i>can escape the grasp of a black hole.</i> <i>Anything-- or anyone--</i> <i>that crosses its outer edge--</i> <i>an invisible boundary known as the event horizon--</i> <i>will never be seen again.</i> <i>narrator: Scientists calculate that in 24 hours,</i> <i>the black hole will reach our planet.</i> <i>But people are already beginning to feel its effects.</i> -<i> As the black hole approaches,</i> we have kind of a global warming on steroids. <i>narrator: The black hole's gravitational force</i> <i>is so powerful that even though it has not yet</i> <i>entered the solar system,</i> <i>it's pushing our planet</i> <i>closer to the heat of the sun.</i> [yelling] -<i> Now it's Christmas in New York</i> and everyone's hanging stockings and putting up Christmas trees, yet it's 110 degrees outside. <i>♪ ♪</i> <i>narrator: As the black hole enters the outer solar system,</i> <i>people everywhere notice an ominous sign</i> <i>that it will be arriving soon.</i> - [speaking foreign language] <i>narrator: A strange effect called gravitational lensing.</i> - The black hole acts like a lens that's placed in front of the distant background stars and galaxies. And it distorts them and it warps them. - You can think of it as simply a cosmic lens. It's the universe's spyglass in a way. -<i> It would be extraordinarily unsettling</i> to the see the familiar patterns in the night sky warped and distorted <i>by an object that's filling more and more of the horizon.</i> <i>narrator: This is the first visual sign</i> <i>that the greatest disaster in the history of mankind</i> <i>is upon us.</i> <i>♪ ♪</i> <i>As the black hole moves through space,</i> <i>it hurls comets and asteroids</i> <i>in every direction,</i> <i>which serve as warnings to people around the world</i> <i>that doomsday is near.</i> - Some of the asteroids will go flying in toward the sun, many away from the sun. But those flying toward the inner solar system would start colliding, in some cases, <i>with the planets</i> <i>and with the Moon.</i> <i>♪ ♪</i> <i>♪ ♪</i> <i>- The impact that occurs to the Moon is devastating.</i> This isn't a quick, bang, done kind of scenario. You're watching it over a half hour. <i>Material is beginning to fan out.</i> It's coming toward the Earth. <i>narrator: As people everywhere look up into the sky,</i> <i>all they see is devastation.</i> - Watching the Moon disintegrate in the night sky is an absolute psychological effect. <i>You have cultures based on the Moon.</i> <i>The Moon's our friend, it causes the tides,</i> prevents things from hitting us. Watching that being destroyed, it's an apocalypse unto itself. <i>♪ ♪</i> <i>narrator: Black holes, like the one heading toward Earth</i> <i>form when massive stars die.</i> <i>The remnants from the star implode</i> <i>like an enormous building</i> <i>collapsing onto itself.</i> - A black hole is the result of a gravitational collapse <i>narrator: All the material from the star</i> <i>is crushed down to a small pinpoint.</i> <i>The fact that so much mass is concentrated in one spot</i> <i>is what gives a black hole enormously powerful</i> <i>and destructive gravitational forces.</i> -<i> If you have enough material</i> crammed into a relatively small volume, its own self gravity will grow stronger and eventually the gravity is so strong that nothing, not even light, can escape. <i>♪ ♪</i> <i>narrator: Albert Einstein first predicted</i> <i>the existence of black holes in 1916,</i> <i>when he presented his equations of general relativity.</i> <i>Although the first one</i> <i>wasn't spotted until 1971.</i> <i>Now scientists say millions of them exist</i> <i>throughout the galaxy</i> <i>and some of them move rapidly through space.</i> <i>♪ ♪</i> -<i> We used to think that black holes</i> were stationary, but we were shocked-- shocked to find that there are rogue black holes that wander across the galaxy. <i>♪ ♪</i> <i>narrator: As the black hole moves closer to Earth,</i> <i>its gravity continues to send asteroids</i> <i>crashing into the planet.</i> <i>♪ ♪</i> <i>A meteor streaks through the sky over Barcelona.</i> <i>♪ ♪</i> [explosion booms] <i>- You're seeing a flash of light.</i> Then a big, hot, expanding balloon of gas.

[yelling] <i>♪ ♪</i> [explosion booms, screaming] <i>narrator: As the first shock wave passes overhead,</i> <i>people just outside of the meteor impact site</i> <i>are safe, for now.</i> <i>♪ ♪</i> <i>But the black hole has only just started</i> <i>to wreak havoc on planet Earth.</i> <i>Can mankind survive?</i> [explosion booms] - This is devastation from space that there's nothing you can do about. <i>narrator: A black hole--</i> <i>the remnants of a dead star</i> <i>with a gravitational force so strong</i> <i>that nothing can escape its clutches--</i> <i>is heading straight towards planet Earth.</i> <i>Can you survive?</i> <i>♪ ♪</i> <i>As it enters the solar system,</i> <i>the black hole's immense power</i> <i>has already unleashed devastation on mankind,</i> <i>hurling meteors that destroyed the Moon</i> <i>and devastated cities across the globe.</i> [explosion booms] <i>People across the world struggle to cope</i> <i>with these unprecedented disasters,</i> <i>and fear what catastrophe will strike next.</i> - Everyone, rightly so, is wondering "What can we do? What's the next step? How do we get through this?" <i>narrator: The scientists who discovered the black hole</i> <i>realize that nothing can alter its path.</i> -<i> There's no way we're gonna deflect it,</i> <i>move it out of the way.</i> <i>It's not like an asteroid</i> where you could park a spacecraft near it and gravitationally pull on it or explode a bomb next to it and deflect a little bit. <i>It's just too massive.</i> <i>narrator: As the black hole moves closer to our planet...</i> <i>♪ ♪</i> <i>People everywhere see something extraordinary</i> <i>The photon sphere.</i> <i>A place where gravity is so strong</i> <i>that light travels in circles around the black hole,</i> <i>filling the sky with streams of red and green light,</i> <i>known as auroras.</i> -<i> What anyone on the surface of Earth would see,</i> looking at the photon sphere would be an incomprehensible, perhaps, display of half imagery, <i>a light show, radiation.</i> I mean, this would be something that's almost impossible to describe. <i>The effect this would have on the Earth</i> <i>is the radiation and the light energy</i> hitting the atmosphere would cause aurora that would light up all over, <i>which is essentially turning the atmosphere</i> <i>into a sort of florescent bulb.</i> <i>♪ ♪</i> <i>narrator: These unearthly images flash across</i> <i>people's eyes just for a moment</i> <i>as the Earth passes through the photon sphere.</i> <i>And then they're gone.</i> <i>♪ ♪</i> <i>With people enduring</i> <i>unprecedented disasters everywhere,</i> <i>some of America's military and political elite</i> <i>gather in Cold War-era nuclear bomb-proof bunkers...</i> [alarm blaring] <i>Like Colorado's Cheyenne Mountain,</i> <i>which is buried under 2,000 feet of granite.</i> <i>- For reasons that are obvious in the context of the Cold War,</i> <i>the U.S. military set up their strategic defense</i> <i>in Cheyenne Mountain.</i> <i>And with good reason.</i> <i>The Earth naturally</i> cooked these very tough rocks that would naturally withstand the direct impact of a nuclear weapon or several. <i>And it would make a robust outpost</i> <i>for humanity to try and set up a last stand on Earth.</i> <i>narrator: Traveling at more</i> <i>than a million miles an hour,</i> <i>the event horizon--</i> <i>the invisible boundary of the black hole--</i> <i>closes in on our planet.</i> <i>And once the threshold is crossed,</i> <i>there's no escape.</i> <i>- Crossing an event horizon, is similar</i> <i>to going over Niagara Falls.</i> Imagine that you're in a boat and you know that the falls are coming, because the water gets faster and faster. And before you hit the edge, there's still a possibility of you paddling hard enough to get to the side. <i>However, once you go over the edge of the falls,</i> <i>there's no going back.</i> <i>You can't paddle hard enough to get you back up the falls</i> <i>and to safety.</i> <i>Niagara Falls is very similar</i> <i>to the event horizon of a black hole.</i> <i>Once you cross the event horizon,</i> there's no possible way to escape. - If you get so close to a black hole that you're in the grip of the gravitational field, then no matter what you do, you're doomed to fall into the black hole. <i>♪ ♪</i> <i>narrator: As the black hole's gravitational forces</i> <i>strengthen their grip on the Earth...</i> [explosion booms] <i>Does humanity have any chance of survival?</i> <i>♪ ♪</i> <i>narrator: In 1916,</i> <i>Albert Einstein first predicted</i> <i>the existence of black holes--</i> <i>objects from space that suck in</i> <i>and destroy everything in their path.</i> <i>If we came in contact with a black hole today,</i> [alarm blaring] <i>is there any way to survive?</i> <i>♪ ♪</i> <i>For the last 24 hours,</i> <i>people around the world</i> <i>have been watching in horror</i> <i>as a supermassive black hole speeds toward Earth.</i> <i>It has already unleashed apocalyptic light shows,</i> <i>scorching temperatures,</i> <i>and massive asteroids</i> <i>that have turned the Moon to dust.</i> <i>♪ ♪</i> <i>Now, our planet is about to pass through</i> <i>its event horizon--</i> <i>the outer boundary of the black hole,</i> <i>where gravity becomes so powerful</i> <i>that nothing can escape.</i> - We reach the event horizon, which is the very literal point of no return. <i>♪ ♪</i> -<i> Nobody on Earth is safe</i> or secure once the event horizon of a supermassive black hole has been breached. But for a while, <i>life would go on on the surface of the Earth.</i> <i>narrator: As the Earth finally passes through</i> <i>the event horizon,</i> <i>it's majestic.</i> <i>♪ ♪</i> <i>Instead of a big bang,</i> <i>there is light.</i> <i>♪ ♪</i> -<i> Once you've crossed the event horizon</i> of the black hole, it's now possible for you to see the light that's inside that can't escape from the event horizon. -<i> You'll notice strange light effects</i> like the light from stars coming in from some weird angle and flashing into your eyes and other weird effects like this. <i>narrator: This cosmic light show may be amazing,</i> <i>but it's also confirmation</i> <i>that our planet has entered the black hole</i> <i>and now we're being pulled closer</i> <i>to the doomsday point at its center,</i> <i>known as the singularity.</i> - The singularity is the point where all of the mass of the star collapsed into. -<i> As the Earth approaches the singularity,</i> <i>the black hole's gravity is stronger</i> on one side of the Earth than the other. And so because of that difference in strength of gravity, <i>there is a stretching and a squeezing effect</i> <i>that gets applied to the Earth.</i> <i>narrator: The black hole's gravitational forces</i> <i>are so strong</i> <i>they literally start pulling our planet apart.</i> [rumbling] [car alarm blaring] -<i> Earthquakes are happening on orientations</i> that don't appear to make any sense. They're not near coastal boundaries or subduction zones, places where you'd expect plates to collide and start to cause earthquakes, or stretch and cause earthquakes. <i>[intense music]</i> <i>♪ ♪</i> -<i> Unlike normal earthquakes, which build up</i> and then dissipate, these earthquakes are getting stronger and stronger and stronger. [glass shattering] -<i> You feel that?</i> <i>narrator: These enormously powerful earthquakes</i> <i>strike everywhere.</i> <i>From Los Angeles</i> <i>to New York and Miami,</i> <i>as well as Australia, Africa,</i> <i>and across Asia.</i> -<i> As the earthquakes are reaching magnitudes</i> seven, eight, nine-- when they start to impinge upon the size of historical massive earthquakes, then infrastructure like dams start to fail. [explosion booming] <i>And so you would see dams not just</i> <i>in seismically active areas,</i> <i>but dams across the world fail</i> <i>and the water behind them would start to rush down</i> through the river valleys. <i>♪ ♪</i> <i>- The chaos never stops.</i> It just keeps going until everything is ripped apart and torn asunder. [rumbling] <i>♪ ♪</i> <i>It's absolutely terrifying to think</i> <i>that a population that's never dealt with this before</i> <i>all of a sudden is being reduced to rubble.</i> <i>narrator: For countless millions,</i> <i>there is nowhere to run or hide.</i> <i>As the death toll mounts,</i> <i>the destruction only gets worse,</i> <i>as ocean levels rise across the planet.</i> <i>♪</i> ♪ - [speaking foreign language] <i>♪ ♪</i> -<i> You're seeing a mound of water on the horizon</i> and as it approaches, the entire level of the water is rising. And this has the effect of carrying water to areas that have never seen water before in that way. <i>♪ ♪</i> <i>♪ ♪</i> [water crashing] <i>♪ ♪</i> - It's gathering speed and pressure because you are forcing all of the water into a smaller and smaller channel. It's like putting a nozzle on a hose. <i>As that wave comes in, it's gathering speed,</i> gathering pressure, and it's beginning to destroy everything that's in its way. [water rushing] -<i> For the three billion people that live on the coast</i> <i>of whatever country they're in,</i> it's absolute chaos. The water is washing into their homes and taking everything away. <i>You've got massive waves.</i> <i>The ocean will never be the same again.</i> <i>To me and to many others,</i> that is the moment where I snap. <i>I am going to die,</i> <i>the Earth is going to be destroyed.</i> <i>It's scarier than hell.</i> <i>narrator: While the few survivors</i> <i>along the world's coastlines have watched</i> <i>their homes, their neighbors,</i> <i>and even their families washed away...</i> Other parts of the planet are left without water. - In some coastal regions, you'd see water flowing away and leaving dry land where there used to be an ocean. <i>What's going on is that as with the tides on Earth</i> raised by the Moon, some areas have more water. That's where you have high tide. And other areas have less water. That's where you have low tide. <i>But with a black hole pulling on the water,</i> <i>the effects would become extreme.</i> <i>And some places would have really deep water</i> and other places would have a huge deficit of water. In fact, they might be completely dry. -<i> The fact that the black hole is able to have</i> such dramatic effects really illustrates just how insignificant the Earth is to these processes. It's like the Earth is a grain of sand on a beach, being flung by a hurricane <i>that marches over the top of it.</i> <i>narrator: As the Earth is pulled closer</i> <i>to the singularity--</i> <i>the black hole's lethal center--</i> <i>will it wipe out civilization as we know it?</i> <i>♪ ♪</i> <i>♪ ♪</i> <i>narrator: It's been 17 minutes</i> <i>since a black hole</i> <i>a billion times more massive than our sun</i> <i>gobbled up the Earth.</i> [crashing] <i>And now the black hole's powerful gravity</i> <i>is stirring up geological forces</i> <i>that are ripping the planet apart.</i> <i>Can any of us survive?</i> - Ultimately, the people wiped out first by the effects of the Earth being drawn closer to the black hole are the nearly three billion people who live in coastal areas. <i>narrator: Enormous tsunamis have destroyed Cairo,</i> <i>Miami, and other cities</i> <i>that lie along rivers and oceans...</i> <i>♪ ♪</i> <i>While massive earthquakes...</i> [car alarm blaring] <i>Have quickly spread across the globe.</i> <i>[rumbling, screaming]</i> <i>♪ ♪</i> <i>This unprecedented geological activity</i> <i>has opened up gashes on the Earth's surface,</i> <i>that allow gas, molten lava,</i> <i>and rock, deep inside the Earth</i> <i>to blast through the surface.</i> <i>In Chicago,</i> <i>citizens experience a kimberlite pipe eruption--</i> [explosions booming] <i>Something that hasn't happened on Earth</i> <i>in 30 million years.</i> - Kimberlite pipe eruptions emerge from the deep mantle of the Earth and as they push their way up, through the solid rock of the crust... [explosion booms] <i>They breach the surface faster than a supersonic jet,</i> <i>leading to an explosion...</i> [explosion booms] <i>Seen from a few miles away</i> <i>that would look quite a bit like a nuclear explosion.</i> - It's like uncorking a champagne bottle.

All black holes are spinning very rapidly. <i>We see that the singularity's actually a ring,</i> <i>not a dot at all.</i> <i>narrator: Einstein's equations predict the Earth</i> <i>might be able to enter the ring.</i> -<i> If you fall through the ring,</i> you actually don't die. You're not spaghettified.
