The Strange Fate Of The Person Falling Into A Black Hole. If you fell into a black hole, you might expect to die instantly. But in fact, your fate would be far stranger than that It could happen to anyone. Maybe you’re out trying to find a new habitable planet for the human race, or maybe you’re just on a long walk and you slip.
Whatever the circumstances, at some point we all find ourselves confronted with the age-old question: what happens when you fall into a black hole? You might expect to get crushed or may be torn to pieces. But the reality is stranger than that. The instant you entered the black hole, reality would split in two. In one, you would be instantly incinerated, and in the other, you would plunge on into the black hole utterly unharmed.
A black hole is a place where the laws of physics as we know them to break down. Einstein taught us that gravity warps space itself, causing it to curve. So given a dense enough object, space-time can become so warped that it twists in on itself, burrowing a hole through the very fabric of reality.
A massive star that has run out of fuel can produce the kind of extreme density needed to create such a mangled bit of world. As it buckles under its own weight and collapses inward, space-time caves in with it. The gravitational field becomes so strong that not even light can escape, rendering the region where the star used to be profoundly dark: a black hole.
The Strange Fate Of The Person Falling Into A Black Hole
The outermost boundary of the hole is its event horizon, the point at which the gravitational force precisely counteracts the light’s efforts to escape it. Go closer than this, and there’s no escape.
The event horizon is ablaze with energy. Quantum effects at the edge create streams of hot particles that radiate back out into the universe. This is called Hawking radiation, after the physicist Stephen Hawking, who predicted it. Given enough time, the black hole will radiate away its mass and vanish.
As you go deeper into the black hole, space becomes ever curvier until, at the center, it becomes infinitely curved. This is the singularity. Space and time cease to be meaningful ideas, and the laws of physics as we know them — all of which require space and time — no longer apply.
What Happened When You Get To The Black Hole
What happens here, no one knows. Another universe? Oblivion? According to IMDB.com, https://www.imdb.com/title/tt0816692/
So what happens if you accidentally fall into one of these cosmic aberrations? Let’s start by asking your space companion, we’ll call her Anne — who watches in horror as you plunge toward the black hole, while she remains safely outside. From where she’s floating, things are about to get weird.
As you accelerate toward the event horizon, Anne sees you stretch and contort, as if she were viewing you through a giant magnifying glass. What’s more, the closer you get to the horizon the more you appear to move in slow motion. Before you ever cross over into the black hole’s darkness, you’re reduced to ash
You can’t shout to her, as there’s no air in space, but you might try flashing her a Morse message with the light on your iPhone (there’s an app for that). However, your words reach her ever more slowly, the light waves stretching to increasingly lower and redder frequencies: “Alright, a l r i g h t, a l r i…”
When you reach the horizon, Anne sees you freeze, like someone has hit the pause button. You remain plastered there, motionless, stretched across the surface of the horizon as a growing heat begins to engulf you. Anne says you are slowly obliterated by the stretching of space, the stopping of time and the fires of Hawking radiation. Before you ever cross over into the black hole’s darkness, you’re reduced to ash.
After all, the event horizon is not like a brick wall floating in space. It’s an artifact of perspective. An observer who remains outside the black hole can’t see through it, but that’s not your problem. As far as you’re concerned there is no horizon. Sure, if the black hole were smaller you’d have a problem. The force of gravity would be much stronger at your feet than at your head, stretching you out like a piece of spaghetti. But lucky for you this is a big one, millions of times more massive than our Sun, so the forces that might spaghettified you are feeble enough to be ignored.
In fact, in a big enough black hole, you could live out the rest of your life pretty normally before dying at the singularity. How normal could it really be, you might wonder, given that you’re being sucked toward a rupture in the space-time continuum, pulled along against your will, unable to head back the other way?
The Laws Of Physics Concerning The Black Hole
On the other hand, the laws of physics also require that you sail through the horizon without encountering hot particles or anything out of the ordinary. Otherwise, you’d be in violation of Einstein’s happiest thought, and his theory of general relativity.
So the laws of physics require that you be both outside the black hole in a pile of ashes and inside the black hole alive and well. Last but not least, there’s the third law of physics that says information can’t be cloned. You have to be in two places, but there can only be one copy of you.
Somehow, the laws of physics point us towards a conclusion that seems rather nonsensical. Physicists call this infuriating conundrum the black hole information paradox. Luckily, in the 1990s they found a way to resolve it. The Strange Fate Of The Person Falling Into A Black Hole.
According to the Theoretical Minimum, Leonard Susskind says that there is no paradox because no one person ever sees your clone. Anne only sees one copy of you. You only see one copy of you. You and Anne can never compare notes. And there’s no third observer who can see both inside and outside a black hole simultaneously. So, no laws of physics are broken. The great secret that black holes have revealed to us is that there is no real. Reality depends on whom you ask. There is Anne’s reality and there is your reality. End of story.
Well, almost. In the summer of 2012, the physicists Ahmed Almheiri, Donald Marolf, Joe Polchinski and James Sully, collectively known as AMPS, devised a thought experiment that threatened to upend everything we thought we knew about black holes.
They realized that Susskind’s solution hinged on the fact that any disagreement between you and Anne is mediated by the event horizon. It didn’t matter if Anne saw the unlucky version of you scattered amongst the Hawking radiation, because the horizon prevented her from seeing the other version of you floating along inside the black hole.
But what if there was a way for her to find out what was on the other side of the horizon, without actually crossing it? Ordinary relativity would say that’s a no-no, but quantum mechanics makes the rules a little fuzzier. Anne might sneak a peek behind the horizon, using a little trick that Einstein called “spooky action-at-a-distance”. This happens when two sets of particles that are separated in space are mysteriously “entangled”. They are part of a single, indivisible whole so that the information needed to describe them can’t be found in either set alone, but in the spooky links between them.
