  • Black holes are dense and scary.
  • They suck up everything in their way.
  • Their gravity is so strong, it bends light and warps time.
  • But what if I told you we might have been wrong about these cosmic vacuum cleaners?
  • For one, they're not vacuum cleaners at all.
  • Uh-uh.
  • Black holes don't go around gobbling up everything in their vicinity.
  • You'd have to cross a black hole's event horizon to get sucked into one.
  • The event horizon is the area around a black hole where its gravity is so strong that you'd have to move at the speed of light to escape it.
  • And moving that fast is simply impossible, at least according to Einstein.
  • That's why there's no escape after you cross this line.
  • The extreme gravity would pull you in and then you'd disappear into the blackness of a black hole.
  • Forever.
  • But as long as you stayed on the safe side of the event horizon, you'd be completely fine.
  • Now, if you had a bad day and ended up sucked into a black hole, it might not be as violent as you think.
  • Despite a black hole's unimaginably massive gravity, it wouldn't instantly crush you like a can of soda.
  • No, you'd experience something that scientists call spaghettification.
  • It's when a black hole stretches you into the shape of spaghetti.
  • If you were approaching a black hole feet-first, your legs would get long and skinny before your head started to change shape.
  • Once you crossed the event horizon, the stretching you'd experience would be extreme.
  • And painful.
  • The black hole wouldn't crush you.
  • Instead, it would rip your molecules apart.
  • This whole spaghettification process would only take a few seconds, maybe a few minutes tops.
  • Sorry, did I say it wouldn't be violent?
  • Yeah, I take that back.
  • This would really hurt.
  • But the good news is, you could still make a comeback.
  • Just not in the same form as you entered the black hole.
  • Yeah, you may have heard that nothing escapes a black hole.
  • But that isn't exactly true.
  • All thanks to Hawking radiation.
  • Turns out, black holes have an interesting quantum phenomenon going on.
  • At the very edge of a black hole's event horizon, particles are constantly forming.
  • Some of them fall back into the black hole, but others escape this monstrosity's gravity in the form of radiation.
  • Hawking radiation, to be specific.
  • Over time, so many particles escape a black hole's event horizon that the black hole disappears entirely, like it never even existed.
  • But it takes an incredibly long time for a black hole to evaporate like this.
  • And unfortunately, you wouldn't be able to reassemble yourself from all those emitted particles.
  • So I really wouldn't recommend jumping into a black hole, especially not into a supermassive black hole in the middle of our galaxy.
  • One good thing that can come from getting close to a black hole is that you could hypothetically harvest its radiation and use it to power things back on Earth.
  • Of course, we're nowhere near that kind of technology, but we have other sources to produce clean, renewable energy, like nuclear fission.
  • I know, when you think of green energy, all that comes to mind is solar panels and wind turbines.
  • Well, that's why I wanted to tell you about nuclear energy.
  • It's zero emission, meaning it doesn't generate harmful byproducts like fossil fuels, it uses way less land than solar or wind farms to produce massive amounts of carbon-free power, and it's super efficient when it comes to waste.
  • Win, win, win.
  • As we aim for a cleaner future, nuclear energy can massively help us reach the goal of 100% clean electricity by 2035, and a net zero emissions economy by 2050.
  • Now, that sounds like the kind of future I'd be looking forward to.
  • You?
  • Well, at least it's a lot better than falling into a black hole.
  • You see, there are different types of black holes.
  • The most common ones are stellar black holes.
  • They are the remnants of stars at least 20 times more massive than our Sun.
  • And because they're so dense, their event horizons can be several kilometers in diameter.
  • Supermassive black holes are monstrous, unimaginably big.
  • The most massive black hole scientists have spotted so far is located in the middle of Phoenix A galaxy.
  • It's got a mass of 100 billion Suns.
  • Yeah, billion with a B.
  • At this point, it's not just a supermassive black hole.
  • It's a stupendously large black hole, or slab.
  • Until recently, scientists thought the biggest supermassive giant was Ton 618, a black hole with 66 billion solar masses.
  • But there's so much of the cosmos we haven't discovered yet.
  • And maybe supermassive black holes can be much, much more massive than we could ever imagine.
  • Scientists still don't know exactly how these cosmic monstrosities formed.
  • And we've got no idea what happens when two of them collide.
  • But it sure wouldn't be pretty for anything caught in between them.
  • But at least we can still observe them to find out more.
  • A black hole's gravity is so intense that even light can't escape it.
  • But that doesn't mean they're the stealthy ninjas of the cosmos.
  • They're very much visible, just not in the way you might think.
  • Because their gravitational pull affects stars around them, astronomers can detect their gravitational effects.
  • They can also see X-rays when something big falls into a black hole.
  • That's because when matter is pulled to the point of no return, it heats up to intense temperatures.
  • But the most mysterious thing about black holes is what lies on the other side.
  • There are theories that black holes can be gateways to other universes.
  • A black hole might be connected to another point in space and time through what's known as an Einstein-Rosen bridge.
  • It's a type of wormhole, and a very unstable one.
  • Scientists haven't found proof of that yet, but that doesn't mean it's not possible.
  • What if we could use black holes as cosmic subways?
  • Where could they take us?
  • Could it be another reality?
  • Another time?
  • While all of this is fun to think about, there's one big problem.
  • Einstein-Rosen bridges are incredibly unstable.
  • They could collapse on you at any moment, trapping you inside a black hole before you could reach your mysterious destination.
  • And even if we were lucky enough to pass through that bridge before it collapsed, there's still no way you could survive it.
  • The intense gravity and radiation would likely destroy you long before you popped out on the other side.
  • Maybe one day we'll learn to travel through black holes, but for now, it's best to stick to exploring our own Solar System.
  • Hey, why not visit Titan, one of Saturn's most beautiful moons?
  • Well, that's a story for another WHAT IF.
