The natural enemy of barrier-type magic, due to the large difference in energy requirement between “generating a black hole” and “maintaining a personal dimension which contains a black hole, breaking all physical laws inside the space.”
Theoretically, when light (electromagnetic waves) in a vacuum goes from one point to another, it takes the shortest and most direct course. In classical physics, light is a ‘straight line’. However, under the effect of any given amount of gravity, light is ‘curved’; thus, in space (space-time) affected by gravity, the shortest course between two points is not a straight line, because light is not exempt from this ‘curvature of space-time’ (gravitational lensing). You can say that gravity causes the curving of space-time.
Objects with more energy than mass (especially astronomical bodies) draw in material and electromagnetic waves in their vicinity towards their centre of gravity; normally, this would not cause any special phenomena. However, when the mass of the object is ‘M’, the universal gravitational constant is ‘G’, and the speed of light is ‘c’,
rg=2GM/c2
once this relationship (function) is established within the radius ‘rg’ (the Schwarzschild radius), the effect becomes different. As the ‘distortion’ from gravity becomes too large, light is not simply ‘bent’, but ‘falls’ into the object’s centre. Illustrated three-dimensionally, this would like a ‘hole’ – ie. a black hole.
As it is divided by twice the speed of light, the value tends be quite small. For example, an object the size of the Moon will have about a Schwarzschild radius of about 0.11mm. Of course, the power of Gravity Magic is to create gravity where there are no objects with mass. To put it another way, Gravity Magic is the ability to warp space-time without a mass/object medium. Again, if the strength of the gravitational influence from the source is ‘F’, universal gravitational constant is ‘G’, the mass of the source is ‘M’, the mass being influenced by gravity is ‘m’, and the distance between the two is ‘r’,
F=GMm/r2
Under the effect of Gravity Magic, as there is gravity there, ‘F’ cannot equal 0. If the left side does not equal 0, then of course the right side cannot equal 0, so even without actual mass, ‘M’ can never equal 0.
As the value of ‘M’ increases under the effect of Gravity Magic, the Schwarzschild radius also increases. Gravity Magic does not require a large space to operate, but that ‘M’ becomes the required value for a black hole to be created.
