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.

It has no mass from what I under stand.
It is just electromagnetic energy.
Post of the day. A+
I think your tagline got Biden-ified. Or maybe it's Biden-ated.
My tagline drifts every few days for some reason
This is a strange definition of dangerous. I’m more worried about getting struck by lightning.
Who thought the Universe could be so sexy?
Dangerous ‘naked’ black holes could be hiding in the universe

As I understand it accretion disks are made mostly of matter which has “radiated” out of a spinning black hole. The “inner” event horizon grows at the equator, and becomes an elipsoid. Where the inner horizon crosses the outer horizon particles form randomly because of heat radiation. The physics of heat radiation in relativistic environments changes to allow matter to radiate. Most of the resulting particles fall back into the singularity, but the particles traveling outward at the speed of light stay in our universe.
Thank thermodynamics law.
More dangerous is the naked arsehole who could be hiding in the White House soon.
All models are wrong; some are useful. While infinities are common in the abstract world of math, no infinities actually exist in the real world. When a math model hits an infinity, it has gone off the rails and ceased being useful.
As a black hole grows in size, its density decreases. There are super massive black holes with a mass density less than water.

Duality. Light is zero mass as waveform.
Photons are particles that have relativistic mass.
Mathematically you can travel faster than the speed of light. Einsteins equations permit it. It is just that you can't travel AT the speed of light , and there is the rub.

#15. If you were Long Dong Silver, having “objects pulled into the hole in a straight line” would definitely happen.
