I am going to call BS on all this explanation. A black hole is not so complicated and all you have to do is think of a "black hole" like the eye of a hurricane. The concept is closely related. Makes me sick to see these so called experts making money and a fake name for themselves off of this nonsense. Yes, this is based on years of saying and writing the same thing over and over again by many "experts" since einstein, which was on to something but not in the direction many others took it after him.

@Aurélie Shp Saw your question in the live chat replay. (Can we see behind a black hole ? If yes, how ?") Please correct me if I'm wrong-but I'm pretty sure it's not a "flat" object, more of a sphere. Essentially, I don't know what you mean by behind, but there's space all around the black hole.

Doesn't time stand still at (or near) the SR? Doesn't that mean that nothing at the current SR has had 'normal time' to fall any closer to the center of the BH. But everything that gets that close adds to the gravity well(field) of the BH, increasing the SR out past the stuff that (in our observational normal space-time) is stuck between previous and currently accumulating layers. I assume that like the net microgravity at the center of the Earth, or uniform microgravity everywhere inside a Dyson sphere, the gravity field would be flat, not curved (as it is outside any solid object). So with matter stuck near the SR, the gravity inside the current SR would be negative, perhaps 'un-building' the original matter of the first 10 solar masses that initiated the BH. However, I don't know if the time dilation is related to the curvature of gravity or its magnitude.

Isn't the mass of the sun or whatever star compressed into zero volume that is called singularity? And then the region around it, or up to the boundary called event horizon is called black hole? What the heck are these "experts" talking about sun compressed into a ball or "tiny tiny" space? Singularity has ZERO VOLUME people!

@you2tooyou2too 3 жыл бұрын
I think they mean that the outside of the marble is the event horizon (EH or SR) or that if the Earth were compressed to that size, the EH would form, and try to collapse the Earth into a singularity, but I suspect this falls apart, since time would be frozen (relative to normal space), so the formation of a singularity would take forever (in our normal space-time). Of course there is no natural process that would compress the Earth that way.

@@you2tooyou2too The Sun's density is 1.4 g/cc, heavier than the liquid water. It emits blackbody radiation, plasma doesn't do that. And the core is super dense, denser than any solid, and pressure and temperature exceeds those of the hydrogen bomb. It should have instantly fused most of the hydrogen in the core into helium as soon as it reached such state. The sun is not a plasma ball. 100% sure of it now.

I don't know that anyone has named it specifically other than 'our central BH',

I think Black Holes are the essential for maintaining the galaxy fabrics. They hold it together Because of gravity they have they make sure gaseous mass matters etc to come together. Then they fuse together. Generate heat then it becomes a planet or star. I think dark matter has some amount of gravity. Which over billions of years that matter come together. Creat a massive gravitational pool. Then they became black hole.

If the nearest black hole, so called 'the size of a grapefruit', is 4 times the distance from the sun as the earth, and it takes only 8 minutes for the sun's light to reach earth, that makes the nearby black hole pretty damn close, which could cause, not just earthly global warming, but solar system warming that science has proved is happening.

Could "global warming" be happening on all the planets of the solar system? And would that not be caused primarily by a nearby black hole? And if a black hole is nearby enough to be heating up the solar system, how on Earth could we escape our fate? I doubt we can. No one can escape the deep chasm of the dark abyss. What activated the nearby black hole? Nuclear bombs? Cern? HAARP, which increases the electro-magnetosphere to the point that Earth appears to be much much much much larger than it really is and wouldn't that cause earth to be more attracted to a nearby black hole than it would be if HAARP had never been used?

As a Black Hole has no heat/energy signature, but incredible density, in what would seem a direct contradiction to how we think incredibly dense masses should act; I can't imagine why it wouldn't be obvious to anyone besides just myself that a Black Hole is composed of a vast collection of what we reference as the Bose-Einstein Condensate. Assuming this to be true, the entire mass of the Black Hole would act as a single element, exist (in it's current state) at or extremely near zero degrees Kelvin, radiate no energy, and convert everything that is drawn into it to a primordial pre-varied and individual elements soup. I would also propose that, after some incredible length of time, it gathers the matter from enough galaxies until it reaches a point where the core of this mass of the Bose-Einstein soup can become no further compressed, and shreds itself into individual elements as a 'Big Bang' event. Regarding the Big Bang: The Big Bang is not the beginning of the Universe. The Universe extends without limits and time has no beginning or end, because time is only our perception of the flow of the elements in and around us. Time is nothing more than a measure of the flow of energy and really no different from measuring current in an electrical circuit. What is referenced as the Big Bang is simply one of an uncountable number of Black Holes, scattered across eternity, shredding. And that is an extremely brief and simplified to a point that it remains only somewhat accurate version of my theory and I'm sticking to it.
@PMC127MAX
@PMC127MAX 4 жыл бұрын
I meant to but forgot to mention how this would relate to the perception of time. Since there would be no perceptible exchange of energy or movement of individual elements within the Bose-Einstein/Black Hole, there would therefore be no flow of energy (time) to measure. And so in a sense time would stop, and if you were somehow able to incorporate your self into the soup and back out again, you would not have experienced what we traditionally refer to as the passage of time. Would this then allow us to describe a Black Hole as a Singularly Singular Singularity?
