Let me see if I have this right:

A black hole is a pile of matter so dense that it’s gravity sucks in photons.

The event horizon is the spot where the gravity is so great that it sucks in photons. Outside of the event horizon, photons can escape.

You ram one black hole into another and their gravity makes them stick together, making a bigger black hole. Presumably, the event horizon moves out a little because of the increased gravity of the increased mass of the black hole.

How many scientists did it take how long to figure this out?

Duh!

Not a big deal; they usually go away after a while.

"..naked singularity.."

Pictures?

There’s an NObama joke in there somewhere.

That doesn’t really answer my question. The equation for velocity is v = d/t or vt = d so as time (t) approaches zero, the distance covered also approaches zero. So it’s not simply a matter of the image being frozen but of the actual movement being frozen, too, at least from the outside frame of reference.

Ahh, Zeno's paradox. The solution (I believe) basically comes down to Plancks Constants, these are units so small that they can't be divided. It is also the idea behind Quantum Mechanics. A singularity would simply be all the Planck constants in a single point.

I was naked and single once.

Well, that’s good. I don’t want a naked singularity in the first place.

You and me both!...............

They did this by constructing an energetic collision between two black holes travelling close to the speed of light, crashing head-on.

This is all on paper, right?

Having zero instruments that have ever reported what happens inside a black hole, we have zero idea about the physics that goes on there.

Your post about time stopping is conjecture.

Further, we have no idea if time itself is quantized (comes in small indivisible units like a tickin clock) or if space is quantized (comes in small indivisible units).

The reasoning in your post fails to take the quantum nature of things into account.

Time is not standing still at the event horizon. That is only the ‘barrier’ where light cannot escape the gravitation field.

Your question is covered by Einstein’s Theory of Special Relativity. Time and distance is relative to the observer.

The effects on time and space at the singularity are still up for debate. I’ve seen different ideas from twisting space to create a wormhole to twisting time for time travel or even dimensional travel. Theoretical physicists love this stuff.

“14% of the total masses of the colliding black holes were converted into gravitational wave energy”

I wonder if they really said this using these words. This almost implies that gravity is a type of energy wave that can be emitted, comparable to eletromagnetic energy. The implications of that are staggering.

The way I understand it, it is not an “image”, it is the actual object. It is not frozen, but slowed down tremendously relative to the outside observer.

I would submit it does answer the question.

For an object falling into a singularity, time is unaltered, in much the same way as a traveler on a lightspeed spacecraft would experience it. It is only altered from the perspective of the observer.

I suppose that if a star were collapsing into a black hole, initially, the observer would see the star’s death frozen in time until the singularity had accumulated enough mass from its surroundings to “grow” the event horizon beyond the star’s initial mass, at which point the “blackness” would swallow up the ghost image.

This is a very racist projection, and I REALLY do NOT want to think about the physicals of “naked singularities” of most of the liberals in Washington who are voting for the next black hole ......

I've always opposed naked singularity.

it is also a point in space where the laws of physics do not apply. Just tells me that our understanding of the laws of physics is flawed and incomplete.

Is the site down? I notice no new articles going up, or at least very few.
