A Little Tiny Point - Stephen Hawking's Universe

[Graybeard]

The formula of the Schwarzschield radius (R) which is that of a black-hole is:
R = 2 G M / c^2,
where G is the gravitational constant,
c is the speed of light,
and M is the Mass of the body.

This means that the radius of a black-hole is directly proportional to its mass or its energy since according to Einstein: E = m c^2. This means that if a black-hole gains energy from the outside its event horizon increases and cannot decrease. Since its event horizon increases when a black-hole gains energy or mass from the outside, it becomes less dense and thus also its interior temperature decreases. This is why the universe, if it is a black-hole, would have a mean cosmic temperature or also a mean gravitational force.

I don't understand why you interpret it as becoming less dense as its diameter increases ? If it gains energy which increases its diameter then its density remains the same.

its possible I'm misunderstanding you.

Hi greg,

...hope you don't mind the butt in here but the expand due to energy acquire is more like the boil of water to me and thus density as a ratio has decreased per the area of measure.? ...that is what I am getting out of it but then i wait the reply as well, good point ponder to the paradox view to me now.

Kind regards g.

I may be mis-interprenting Cosvis.

I find black holes mysterious. I have never been able to satisfactorily explain to myself the difference between the apparent and event horizons.

But you would have to consider the density curve of a black hole. If the centre, as believed, is infinitely dense, then adding more does not change anything. This would seem to lead to the conclusion that the mass that enters is responsible for the diameter increase, and not a change in the expansion/density ratio ?

But I have no idea if I'm correct.

I might add that the speed of light is 0 in a black hole. Some would even say that this makes it a true hole—of nothing.

I see where your model demands the stand greg, but tell me does it have spin? Was it turning as perhaps the Gamma depict now, that plate leave of signature indicates for such a leave to have that shape? that plate is created but by one force and the force is centripetal?
I have to go there to the view and thus the torus... center not so full ..IMHO I will have to go get a donut now and discuss it with sage.

Kind regards g,

Hi G_burnett and all,

I find it interesting when you said G_burnett, "all energy came from matter." In my understanding of the evolutionary process of the universe, the process proceeds from less complicated formation to more complex structures. Thus, in my view, at the origin of the universe there first existed pure energy, with the evolutionary physical laws that governs the evolutionary process of the universe. The first and fundamental stage of the evolutionary process of the universe, in my view, is the formation of matter and anti-matter from pure energy. This process, in my view, is continuous and there exist a balance between the amount of matter, anti-matter and pure energy that exists in the universe.

Hi Graybeard and all,

I think, Graybeard, if you hold that a black-hole ends in a singularity, infinite energy in zero space, then I think, it does not matter about the event or an apparent horizon of a black-hole, because all matter and energy would fall into the singularity. The event horizon would only be the point where nothing could escape the black-hole.

In my view of a black-hole it contains a quantity of mass or energy, that is kept within its event horizon and it cannot escape, since it would take speeds greater than the speed of light to escape it, but according to Einstein, this is impossible. In my view, there is no singularity within a black-hole but the energy or mass or both, move within the volume of a black-hole that has a radius and an event horizon. When energy and mass enters a black-hole from the outside, its radius increases proportional to its quantity of mass or energy and its volume increases proportional to the cube of its radius, and thus its density would decrease since density depends on its Mass divided by its volume.

From my understanding of a black-hole universe, no mass or energy can enter from outside and thus its volume, radius and density will always be constant and thus also its universal cosmic radiation, and its universal gravitational constant.

Yours Cosvis.

Matter and energy to me Cosvis are one an the same but in different state of exist. This is the balance.

In the simple, cool energy down and you have matter, heat matter up and you have energy.

How do you get energy then in a begin is by the clumping of matter in it state of potential to become the other state, energy.

What breaks the balance that may have existed or could have existed between the two states ... this could or may or should be looked at ... is irrelevant in the simple that the whole is cyclic by nature of the all with the razor edge infinite sharp and never really reached to absolute rest state because it is not the natural.

if we say energy came first we say it came from nothing or god and this is not science but creationist and needs to be related to in a thread of same not science.

Thank you for your post

Agreed.

In fact, talking about the density of a black hole other than the average density doesn't really make sense, since we're never going to be able to observe the matter inside anyway. The average density of the black hole can be computed (at least in the Schwarzschild case) as M/r_s^2, where r_s is the Schwarzschild radius of the black hole; i.e. the radius of the event horizon.
