The strange fate of a person falling into a black hole
Canada Goose Outlet It could happen to anyone. Maybe you’re out trying to find a new habitable planet for the human race, or maybe you’re canada goose outlet miami just on a long walk and you canada goose uk site slip. Whatever the circumstances, at some point we all find ourselves confronted with the age old canada goose outlet uk question: what happens when you fall into a black hole? Canada Goose Outlet
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 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 canada goose outlet 80 off 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 outermost boundary of the hole is its event horizon, the point at which canada goose outlet parka 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 more curvy until, at the centre, 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 happens here, no one knows. Another universe? Oblivion? The back of a bookcase? It’s a mystery.

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.
canada goose factory sale 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. canada goose factory sale

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 you reach the horizon, Anne sees you freeze, like someone has hit the pause button. You remain plastered there, motionless, stretched across the surface https://www.canadagoosejacketsforcheap.com of the horizon as a growing heat begins to engulf you.
canada goose uk outlet According to Anne, you are slowly obliterated by the stretching of space, the stopping of time and the fires of Hawking canada goose outlet store calgary radiation. Before you ever cross over into the black hole’s darkness, you’re reduced to ash. canada goose uk outlet

You sail straight into nature’s most ominous destination without so much as a bump or a jiggle and certainly no stretching, slowing or scalding radiation. That’s because you’re in freefall, and therefore you feel no gravity: something Einstein called his “happiest thought”.

After all, the event horizon is not like a brick wall floating in space. It’s an artefact 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 spaghettify you are feeble enough to be ignored.

How canada goose outlet near me 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?
You can’t turn around and escape the black hole
But when you think about it, we all know that feeling, not from our experience with space but with time. Time only goes forwards, never backwards, and it pulls us along against our will, preventing us from turning around.
