I am not a Physicist and I am unused to the terminology you use, however I have an interest in this Universe and often consider areas where knowledge is limited.I wondered how an object such as a singularity could have such massive gravity if it is such a small object.I may well be wrong but I was under the impression that Total Gravity is relative to total mass so if you have a sphere of a specific size technically the pressure of gravity experienced on the surface would be x and as long as the surface area remained constant x would be constant, but if the mass remains the same and the area changes larger or smaller then the pressure of gravity would also change.Gravity Pressure = GForce MassAreaIn short Gp=Gf MaGravity pressure equals the force of gravity divided by the area of the mass producing the gravityIn so much as Gravity is a constant relative to the total mass of an object, this will not change.However the pressure gravity excerpts on an object considered being in a low kinetic state will change as the area of the object changes.E.g. take a planet and reduce the space that exists between the particles of matter so as the total surface area is reduced to a small percentage of the original object.The mass remains constant as does the force of gravity, however the pressure that gravity applies to the remaining surface area will increase.I suspect that it is this variable pressure that is present at the collapse of a star and contributes to the formation of a singularity.The same may well be applied to the Magnetic field strength of an object in a state of stellar collapsePerhaps an expert could revue this for me
Alberto - as you are well aware, if the mass remains constant then the force of gravity remains the same at any given distance from the centre of mass regardless any change in size of the mass. Your answer does not make that clear as the words contradict the formula. You should have said that "...you don't consider the fact that the gravitational force at the surface don't stay the same, but it increases"
As far as I am aware, black holes do not have magnetic fields. So, somewhere between being a star & being a black hole, the magnetic field disappears. I'm not sure at what point that happens.
The simplest black hole has no spin and no magnetic field. This is called a Schwarzschild black hole. A black hole that has a field but no spin is called a Reissner-Nordstrøm black hole. One that has both a magnetic field and spin is called a Kerr black hole.
How can that be? The EM force is mediated by photons, but they cannot escape the black hole. Surely, any magnetic field is generated by the accretion disk, not the black hole itself.
.....If the mass of an object remains the same its gravity must remain the same or if you prefer constant, since gravity is relative to mass........My notion is that gravity is a force and therefore must act upon an objects total surface area, since you have both force and area through transposition you gain pressure, this being the result when you divide force by area.Now since gravity must remain relative to mass the only way an increase in the effect of gravity can be gained is if the area of an object changes and as i initially explained this will happen as the distance between the particles of matter either reduces or becomes greater.
total force of gravity an object can produce cannot exceed its Total mass
sophiecentaur Please explain which masses you are talking about?
I am saying is that in an object which has a set amount of matter and therefore a fixed mass, you cannot have more non magnetic attractive force than is available due to the ratio of mass to non magnetic attractive force.
Humankind’s need to extend his boundaries and encounter and conquer the unknown is both his greatest strength and his ultimate weakness.By moving outside of the comfort zone man has gained new territory and new knowledge.However, in doing, this man has impinged on the boundaries of his neighbours and because of differences in custom and language many wars have been fought.Yet without humankinds need to look over the horizon and gain new knowledge and new territory.We would still be ignorant savages sitting on our arses in mud.I believe that the greatest joy is to exchange information with other human beings, learning from them as they learn from me, and if I have to learn a new language to do this, I will endeavour to do so. However, no matter how intelligent I may be, it will still take me some time to achieve fluency up until then I will no doubt amuse with pigeon tongue.Perhaps this is more expressive:Potential gravity of a mass in terms of spatial distortion Volume of the mass in stasisWill produce X it terms of pressure or perhaps forcePerhaps written as X=Gm Vm
It would appear ladies and gents or otherwise that we are entering into the realm of classical versus modernist,
Surely this is why most asteroids 'tumble' as they move in their orbits?
by the time you have reached about 3-4000 degrees C everthing has turned into gas and no compounds can hold together.
Go hotter still and you find that the protons and neutrons start to break down into their constituent quarks but as these are joined together by extremely strong forces unless the pressure is very great you create loads of new particles from the energy effectively creating lots of new matter
Newton believed that gravity was infinite as did Einstein, for something to be infinite it has to exist within an infinite space. I believe in certain things but I do not place faith in them as Faith is the province of religion and requires unquestioning belief, I question everything.
No I will revise this,gravity exists as a point of Zero potential and any mass will fall towards this point,
Your knowledge of history is somewhat limited Philosophers are rarely humble in fact the only one I can think of was Pythagoras, Philosophers are usually cantankerous and will fight at the drop of a hat, especially the Celts. Socrates by all accounts was a thoroughly annoying individual.At the center of hollow sphere gravity will have zero potential.Gravitational force bringing a mass from an infinite distance will have a value of zero.Forget Time distortion Ask DB about archetypes.
