A Little Tiny Point - Stephen Hawking's Universe

[Profpat]

Hi Cosvis;

Hawking radiation

Main article: Hawking radiation
In 1974, Stephen Hawking showed that black holes are not entirely black but emit small amounts of thermal radiation.[30] He got this result by applying quantum field theory in a static black hole background. The result of his calculations is that a black hole should emit particles in a perfect black body spectrum. This effect has become known as Hawking radiation. Since Hawking's result many others have verified the effect through various methods.[31]

Doesn't this mean that black holes do lose energy?

Best,

Pat

P.S. I believe Hawkings believed the lost information didn't go to the edge of our universe but into a parallel universe.

Hi Austintorn, Pat and all,

I thought that Stephen Hawking no longer holds for the theory of the evaporation of black-holes. I certainly cannot assure it but I think, the method of virtual pair formation of matter and anti-matter could possibly be a method in nature where-by matter and anti-matter are continuely being formed. Just as matter and anti-matter is continuely being transformed back into pure energy, so there could be a natural method in nature where-by matter and anti-matter is coninuely being formed. When the virtual pairs of matter and anti-matter are formed, they separate, one into the matter field and the other into the anti-matter field. If the universe is a pure black-hole it must contain all energy of the universe, so that no energy would be found outside the universe.

Yours Cosvis.

Hi Cosvis;

You are right there is no way out of our universe, by defintion. And as soon as the universe expands into the void, it becomes the universe.

This however does not make it a black hole, if anything it would be more like a white hole, forever expanding and not contracting like a black hole.

Best,

Pat

Hi Pat and all.

My understanding of a black-hole is that its size can only increase or decrease when it gains mass or energy or it decreases its energy, since its radius is directly proportional to its quantity of energy. If the universe is expanding it must gain in energy. Where does that energy come from? It can not be created since energy cannot be created nor destroyed. Its energy can only come from the beginning of the universe because all energy of the universe existed at the beginning of the universe.

Also pure energy or quanta particles cannot travel faster or slower than the speed of light, because they cannot loose energy. If the universe was a small point at its beginning and than expanded, than when it reached it's event horizon, it could not go beyond it because it can not travel faster than the speed of light.

Hi Cosvis:

I thought a black hole became smaller, albeit more dense, as it absorbed more mass.

Hi Pat and all,

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.

Yours Cosvis.

We live in a black rabbit hole of Wonderland.

Hi Pat, Austintorn and all.

I am glad you think we are living in a wonderland, Austintorn; it is certainly a wonderful universe to live in and to know that it will last for ever, is even more wonderful.

I wonder, if you have ever wondered Pat, why we have so many constants in science. eg. the constant of the speed of light c, the constant of the universal force of gravity G, and so many other? I think we have so many constants in our universe because they are all connected. Let us assume that the universe is a black-hole, than the formula of its radius would be R = 2 G M / c^2 where G stands for the gravitational constant and c stands for the speed of light. M stands for the total mass or energy of the universe and since no energy can be created or destroyed , its quantity must also be constant. If all the functions on the right side of the formula are constants, than the R or the radius of the universe must also be a constant; in other words the universe must be stable and constant.

Yours Cosvis.

Hi Cosvis, interesting postulations and thus above caught my attention ... Energy view held is the fluid transient form of mass in the relative state of having potential of fluidity and motive force as substance with dimensional matter becoming energy.

In saying thus we are able to predict the event prior, that all energy came from matter, released in the static relative state of potential, to be energy.

How did this happen would be with the logic that containment broke ... just my ponder

kind regards graham

Alternatively, if the Radius were increasing, then some part of the right side of that equation must be changing as well.

If the speed of light were decreasing, that side of the equation would increase (just like taking a fraction of say, 2/4ths, and making it 2/3rds, then 2/2, 2/1, etc).

Interesting as I hadn't considered thinking about it that way, yet it provides a way to look at it which produces a result I knew intuitively, that the speed of light was changing over time, and should continue to do so as the universe expands.

Note: just because the speed of light itself varies, that doesn't violate the postulate of relativity which states that observers in different state of motion will always measure it's speed to be a constant, as they are actually referring to two different aspects of the universe.
