Dangerous 'naked' black holes could be hiding in the universe

Black holes are regions of infinite density, known as a singularity. And according to mainstream physics, each of these cosmic matter munchers is fringed by an event horizon –- a boundary where once you fall in, you never come out.

But what if some black holes are naked — completely lacking such frontiers? As far as we can tell, singularities are always wrapped in event horizons, but a more detailed look at the math of general relativity suggests that doesn't have to be the case.

If such naked black holes dot the universe, new research reveals how we might be able to detect one: by looking at the ring of light surrounding it.

'The Emperor Has No Clothes' Black holes are a consequence of the mathematics of Einstein's theory of general relativity. Those equations tell us that if a clump of matter collapses on itself into too small of a volume, the gravity of that matter will just keep shrinking it ever smaller until it crushes into an infinitely tiny point. That point is called a singularity, and it's a signal that the math we're using to describe spacetime is completely breaking down.

The gravitational pull of a singularity is infinitely strong. Objects can be pulled toward the singularity faster than the speed of light. Near a singularity, the physics of general relativity can no longer predict the future trajectory of particles — which is one of the main points of physics. Without the power to make predictions, physics falls apart.

I knew this when I was 18 years old. It is called the Demonic Democrat Party.

When responding, I'd like to ask you one last time. Conduct yourselves with the utmost maturity.

When I was a young and naive youth, I was warned to stay away from these, no matter how much attraction they exhibited.

Faster than the speed of light. I though the speed of light was a constant and was as fast as any thing could travel.

Ahhh... but Hawkin speculated the even horizon is a hologram where the information is stored and of course, through Hawking radition it can be released back into the universe. So you might need to clarify that you never come out the same. lol.

“Without the power to make predictions, physics falls apart.”

That’s why you see so many physicists at the horse track.

What about naked fuzzballs? Are they dangerous?

You might not go faster than the speed of light but if you turn right at the Arches de Chaos and get on the Celestial Highway. You could cut a million years of travel down to a decade. source: Fast superhighway through the Solar System discovered

Objects are not pulled into the hole in a straight line.

They have to circle the drain like Earth's solar system is to the Milky Way's black hole.

Barry: “I’ll take black holes for 500 Alex.” Alex: “Name the Black Hole you are commonly associated with”. Barry: “What is Reggie’s?” Alex: “Right again!”

If they are south of the equator do they circle in the opposite direction?

In the plane of the Milky Way, viewed from one side it is clockwise and from the other side, counter clockwise.

But relative to time vs gravity, what is clockwise?

I’m no physicist, so I guess it’s OK that I don’t get this. If a black hole has no event horizon, it seems to me that would mean that light would always be able to escape the point of singularity - which would mean it’s not a black hole at all.
