Where Nature Hides the Darkest Mystery of All

There’s no boundary quite like a black hole boundary. No known object in existence has as clear a division between “inside” and “outside” as a black hole. We live and see the outside, and no probe will bring us information about the inside. We can send radio messages or robotic spacecraft, but once they cross over into a black hole’s interior, we’ll never get back those emissaries … or any information about what happened to them.

The boundary of a black hole is its event horizon. It’s not a surface in the usual sense—there’s no physical barrier—but it’s very much a real thing. Outside the horizon, an object can escape the black hole’s gravitational pull if it’s moving sufficiently fast; inside, it would need to move faster than light-speed, something forbidden by the laws of nature.

In a meaningful sense, a black hole is its event horizon, since we can’t observe anything inside it by any method. The interior is nature’s biggest secret, enshrouded by a barrier that lets everything in but nothing out.....

The interior of a black hole isn’t merely an inaccessible region of the cosmos. It’s a laboratory for the most extreme physics: the strongest gravity and the most intense of quantum processes. For that reason, physicists are interested in understanding what goes on inside, even while they are frustrated by the lack of direct experiments or observations that could test their ideas.

Something we will never know for sure.

[WorkingClassFilth]

That’s not what I thought at sixteen.

[West Texas Chuck]

There are a lot of things around that can make you unhappy and frantic. Black holes ain’t on my list.

I say bring ‘em on, the ultimate cure for Obama.

This areticle are about the plain black holes, not A holes.

Obviously written by someone who has never heard of “the Beltway”.

Sounds like liberalism.

I know there are at least a couple of my socks in there.

Quantum entangle two particles, and then send one into a black hole, while leaving the other here safely on Earth. What happens?

[Bullish]

I know what’s inside... Darkness.

I thought that the latest theory was that the information that gets sucked into a Black Hole is somehow smeared across the surface.

Go during the day when its light there.

send in O with a smart phone to take pictures for us

[MtnClimber]

Do you think an 0bama phone would break through like breaking into a small business by 0bama’s son?

[faithhopecharity]

an Obamaphone is POWER, man!

with an Obamaphone you can do ANYTHING! Like breaking into peoples’ homes and cars and stores and....and....

(steal yourself some $700 tennis shoes and you become Invincible!)

Ted danson a true black hole married to the fat black hoe

[Nuc 1.1]

An excellent question.
