Theory to the Mystery of the Super Massive Black Holes

laxies located at great distances from the Milky Way, publication 1929.The speeds of stars in these galaxies have been measured based on the redshifts of the light they emit.The speed of a star results in a change in the wavelength, which is called a redshift.In the Universe, all stars at great distances shift their wavelength towards red, and therefore, it has been inferred that the Universe is expanding.By using the redshifts, Vera Rubin measured the rotating speeds of galaxies and found that the stars rotate in the outer part of the galaxy approximately at the same speed, Ref. [1] 1983.The speed of rotation is zero at the center of the galaxy, after which it rapidly increases until at a certain value it remains constant.The matter of a spiral galaxy is concentrated into a great, dense bulge at the center of the galaxy, and the rest of the galactic matter forms a large rotating spiral disk.The gravitational force of this kind of galactic matter distribution reduces approximately inversely proportional to the square of the distance from the center of the galaxy.Therefore, the constant value speed distribution is not only resulted from the visible and dark matter in the center bulge and disk of the galaxy.There must be a great amount of some other types of dark matter affecting the rotation of stars.The question is what type of mass distribution would achieve constant rotational speed distribution on the outer part of the galactic disk.It should probably be a ball-shaped dark matter formation above the galactic disk.A sufficient amount of dark matter above the galactic disk was not found.The measurements of the space telescope Hubble have not given support to this theory, Ref. [3] 1995.It seems that dark matter in the halo of the galaxy is not so massive that it could explain the constant speed distribution.After that, the search for dark matter has primarily concentrated on fundamental particles.It must be a fundamental particle that has mass and force of gravity.The particle must not have any other forces because otherwise it would have been observed by now.Fundamental particles like this have been searched in mine shafts that enable minimal disturbing factors.Richard Panek has written on the latest difficulties in the research of the Universe, Ref. [4] 2020.Astronomers have calculated how fast the universe is expanding.Two different calculation methods have two different results.The cause of the discrepancy may be the fact that physics has new unknown phenomena.In Ref. [5] 2022, Anil Ananthaswamy has written about the same theme: How fast is the Universe expanding?How much does the matter clump up?The final conclusion is: We are missing something.
In Ref. [6] "Galaxy Rotation in the Space of Four Distance Dimensions", the dark matter mystery has been solved in the Universe of four distance dimensions.
Ref. [6] presented a new idea that dark matter is located at the fourth distance dimension above the center of the galaxy.In the same manner as a structure of three dimensions can be drawn in the cross-sections of two dimensions, a structure of four dimensions can also be drawn in the cross-sections of two or three dimensions.Therefore, the determination of the location of dark matter in the fourth dimension is no problem.The study in Ref. [6] contains the solution to the dark matter mystery of spiral galaxies by using the space of four distance di-DOI: 10.4236/wjm.2023.135006109 World Journal of Mechanics mensions x,y,z,x', in which x' is the fourth distance dimension.The four-dimensional mass M, which generates the main gravitation field of the galaxy, is located in the fourth dimension at the distance x' = X' and the other dimensions are zero x = 0, y = 0, z = 0.The speed distribution curve of the four-dimensional mass v M is the effect of the mass M on the total rotational speed of the galaxy.
Ref. [2] has presented the rotational speed distribution curves of the galaxy NGC 3198.The speed distribution curve of the galactic halo in Ref. [2] corresponds to the speed distribution curve v M of the four-dimensional mass M in Ref. [6].In order to find out how well this four-dimensional model functions, the speed distribution curve v M was calculated, and it was compared to the halo speed distribution curve of Ref. [2].The conclusion was that the calculated distribution curve v M is a good match to the halo curve in Ref. [2].Furthermore, four rotational speed distribution curves v M were calculated using different values of the distance X', which yielded different values for the maximum radius of the galaxy.
In this manner, the different galaxy models of Ref. [1] were obtained, and therefore, this solution to the dark matter mystery was proved.
Ref. [7] "The Solution to the Dark Energy Mystery in the Universe of Four Distance Dimensions" solves the mystery of dark energy by using the structure of the four-dimensional Universe.The model of the Universe is the surface volume of the four-dimensional spherical Universe.This type of structure of the Universe creates the same kind of an accelerating redshift increase that has been measured.The cause of the redshift in this model of the Universe is its structure, and therefore, there is no accelerating expansion of the Universe.In order to prove this theory, the model of the surface volume of the four-dimensional Universe was constructed, the equation of the redshift caused by this Universe was solved, and the theoretical equation was shown to be the same as the measured redshift in the Universe.The measured redshift in the Universe was obtained from the derivative of the model of the expanding Universe in Ref. [8].A similar model of the Universe has been constructed by NASA [9].The four-dimensional model of the Universe in this study yielded the Universe that was found to have decelerating expansion until this point of time and a Big Bang that was not very big.
Black hole is a body of space which is so massive that even the speed of light is not enough to escape it.In this publication the function of the black holes is studied in our Universe of three distance dimensions, and in the super Universe of four distance dimensions.In the for-dimensional Universe, the black holes are rotating galaxies, and if they are near enough to our three-dimensional Universe, they can act as quasars.The quasars spit matter into space, and therefore it can be inferred that their black holes are out of our three-dimensional Universe.No matter can escape the gravitational force of that kind of black hole.Astronomers have been searching for suitable black hole candidates, and the most famous are, Ref. [10]

Method of Calculation
In the following, a simple method has been presented to see the space of four distance dimensions, and to perform calculations in it.In Figure 1, a box is drawn in the three-dimensional space x,y,z.On Figure 2, the same box is drawn in the two-dimensional space z,x and on Figure 3 it is drawn in the two-dimensional space z,y.There is still a third possible set of coordinates x,y, but it is not needed to determine the shape of the box.Here, it is seen that a structure of three dimensions can be drawn in a two-dimensional coordination system.In the same manner, a structure of four dimensions can be drawn in coordination with the three dimensions x,y,z, y,z,x', x,z,x', x,y,x'.If the structure is simple, it is possible   that only one two-dimensional co-ordination is needed to determine the form of the structure.

Calculation of the Rotational Speed of Galaxy
In Figure 4, the four-dimensional space x,y,z,x' is presented as a drawing of two-dimensional coordination system x,x'.The Universe is comprised of three dimensions x,y,z and the enlarged Universe has four dimensions x,y,z,x'.The coordination system of Figure 4 is constructed from the coordination system of Figure 1 so that the galaxy rotates at the plane of x,y coordinates and the coordinate z has been exchanged to the coordinate of the fourth-dimension x'.In the figure a star of mass m rotates round about the center of galaxy O.The rotation axis of the galaxy is the coordinate x' and the four-dimensional mass M is at the distance X' from the center of galaxy O.The mass of the star m and four-dimensional mass M draws each other with the force of gravity.Because the three-dimensional gravity force of the star is lacking the force of fourth dimension, the force that has an effect on the star is Fcosα.
It seems that this model fits very well for the measurements.Near the center of galaxy, rotational speeds from the redshift measurements and theoretically calculated speeds from the light intensities of rotating stars have relatively good correspondence.In the center of galaxy, the gravity force between the star of mass m and the four-dimensional mass M is in the x' axis direction, and it disappears completely.At the border areas of the galactic rotating disk the gravity force of the mass M increases in the x axis direction Fcosα which is according to the redshift measurements.Even over 90% of the gravity forces acting at the border areas of galaxy cannot be explained by the masses of the known visible and dark matter.This model of the space of four dimensions can explain the weird rotation speeds of galaxies.
The mystery of dark matter in the rotation of galaxies is a common subject matter in the study books of cosmology, Ref. [11].This mystery has been solved in this paper by the gravitational force of four-dimensional mass in the space of four dimensions.In Figure 5, the star with mass m rotates round about the center of galaxy along the circle of radius R. As the star rotates, the force of gravity which has an effect on the star is equal to the centrifugal force of its rotation movement.
The differentia of the gravitational force is equal to the differentia of the centrifugal force.
( ) ( ) ( ) If x < R, the differentia of the gravitational force increases the centrifugal force.If x > R, the differentia of the gravitational force decreases the centrifugal force.
Therefore, this equations shows that the halo mass distribution structure cannot be the solution to the galaxy rotation speed mystery because Equation ( 1) cancels as halo structure continues about the same mass M(x) on the both sides of the location of the mass m, and there is no rotation speed generation.The dark matter which rotates the galaxy must be on the rotation axis, or near it.
Summation yields the centrifugal force component of the visible galactic mass The star's rotational speed round about the center of the galaxy is v.The speed distribution components of the star's rotational speed v are as follows: the speed distribution component from the visible mass is v n and from the ordinary dark matter is v p and the speed distribution component from the four-dimensional mass M is v M .The centrifugal force components are from visible mass, from ordinary dark matter and from the four-dimensional mass M.
( ) The following equation is obtained by adding the three centrifugal force component.
The total rotational speed curve v and the rotational speed curve of visible mass v n are known, the rotational speed curve of ordinary dark matter v p is not knows, but it can be concluded that it is the same form as the speed curve of the visible matter v n .The rotational speed curve of the four-dimensional mass M v M is not known and it will be calculated by using the knowledge of the rotational system.In Figure 6, a star which mass is m rotates round about the center of galaxy O at the distance R. The four-dimensional mass M is on the rotation axis x' at the distance X' from the center of galaxy.The galaxy has two rotational axes z and x'.This can be seen as follows: The rotating star system in the four-dimensional space x,y,z,x' in Figure 6 is transformed into the system of oscillating atom about zero point O in the three-dimensional system x,y,x'.If the oscillating atom is at the point of the mass m, and it is oscillating along the axis x about the point O, it has two axes about which it oscillates y,x' in the three-dimensional space x,y,x'.In the same manner the star rotating round about point O has two axes z,x' round about which it rotates in four-dimensional space x,y,z,x'.The gravity force of the three-dimensional mass decreases in the inverse value of the square of the distance, and it can be supposed that the gravity force of the four-dimensional mass decreases in the inverse of the cube of the distance, and therefore, the gravity force of the four-dimensional mass M is ( ) ( ) in which the component at the direction of x-axis is The centrifugal force component corresponding to the four-dimensional mass M is ( ) Calculation of the speed distribution curve of the four-dimensional mass v M .
The gravitational force is equal to the centrifugal force. ( The speed distribution component of the four-dimensional mass M ( ) The four-dimensional mass M ( ) ( ) Equation ( 10) at the distances R 1 and R 2 from the center of galaxy ( ) By dividing the two equations above The distance of the four-dimensional mass M from the center of galaxy The values of the total rotational speeds v have been calculated from the redshifts of the rotating stars of the galaxies.The rotational speed distribution component of the visible stars v n has been calculated from the gravity force of their mass, which has been calculated according to their light intensity, and the result of which is like the distribution curves in Figure 7.It can be supposed that the speed distribution curve from the ordinary dark matter v p is the same form as the speed distribution curve from the visible light v n .By using these three speed distribution curves it is possible to calculate with Equation (6) the speed distribution curve which corresponds to the speed distribution curve v M of the four-dimensional mass M. In Ref. [2] has been calculated the halo speed distribution curve, which corresponds to the curve v M of Equation (11).They can be compared.The system of galaxy rotation of this study is a hypothesis, and it must be proved to be correct or not correct.With a pair of the rotational speeds v M1 and v M2 and the radii R 1 and R 2 it can be done.
The speed distribution curves of the galaxy NGC 3198 have been presented in Ref. [2].The speed distribution curve of the galactic halo in that publication corresponds to the speed distribution curve v M of the four-dimensional mass of this study.In order to find out how well this four-dimensional model functions, the speed distribution curve v M of the four-dimensional mass has been calculated by using these rotational radius and speed values.
This is the best fitting to the halo component of the speed distribution curve in Ref. [2].The fitting succeeded well enough, and it proved that the four-dimensional mass is real.

Calculation of the Black Hole
The rotational speed of the super massive black hole is the speed of light c = 300,000 km/s.The rotational speed distribution curve of the four-dimensional mass M, v M in Figure 8, and it corresponds to the component of halo speed distribution curve of the galaxy NGC 3198 in Ref. [2].The four-dimensional mass which produces the speed distribution curve is M = 80 × 10 61 kg, and its location X' = 8.8 × 10 20 m at the four-dimensional rotation axis.The dark matter  1) and (2).Therefore, the dark matter of the galaxy NGC 3198 cannot be a halo structure.It could be a black hole, but because there is no black hole at that position near galaxy NGC 3198, the dark matter is not in our three-dimensional Universe.In this study, a theoretical Black Hole is calculated so that the location of the four-dimensional mass M = 80 × 10 61 kg, X' = 8.8 × 10 20 m is shifted at the rotational axis towards the center point of the galaxy's rotation.
The maximum value of the speed distribution curve of the four-dimensional mass v M is at the point in which the derivative of the speed distribution curve is zero.Equation ( 11) Derivation of the speed distribution curve The maximum value of the speed distribution curve v Mx is at the radius R x ( ) The maximum value of the speed distribution curve v M is at the point X' = R.It is also about the maximum radius of the galaxy NGC 3198 R = 9.0 × 10 20 m in Ref. [2].In Figure 9 the speed distribution curve v M which is generated by the four-dimensional mass M = 80 × 10 61 kg, X' = 8.8 × 10 20 m is shifted toward the center point of the galaxy, and the maximum speed of the distribution curve increases.
The whole Black Hole is in our three-dimensional Universe when the galaxy's fourth dimension X' is zero.
The radius of the Black Hole R 0 corresponds to the speed of light (300 × 10 3 km/s) The surface of the four-dimensional sphere at the radius R from the center of the sphere is a volume, and therefore the surface of a Black Hole is a volume.
The volume of the center of a Black Hole is infinite.
The maximum radius of the galaxy R x is at the point of the maximum value of the speed distribution curve v M .Between the maximum value of the speed dis- tribution curve v M and the center point of the galaxy there is a large hole in the gravitational field of the Black Hole, and matter falling into this hole produces the galaxy in our Universe.Therefore the maximum radius of the galaxy R x is at the point of the maximum value of the speed distribution curve v M .Black Hole's mass can be calculated from Equation (23).In Ref. [7] hard evidence has been presented that our three-dimensional Universe is the surface volume of four-dimensional sphere.In Table 1 the fourdimensional masses of the Black Holes at the center of the sphere have been calculated, and it seems to be that at the longer distance there are more massive Black Holes, Equation (22) X' = R x .
From Equation ( 11) the effect of four-dimensional mass M on the rotational speed distribution curve v M is as follows: As it is obvious that the effects of three-and four-dimensional masses are the same, except for the effect of the distance R, it can be inferred that the coefficients of gravity are the same, except for the quality, γ = 6.67 × 10 −11 N·m 3 ·kg −2 .
In Figure 11 a star is falling into the Black Hole.The transformation of the relativity measurements compatible with the invariance of the velocity of light is according to Ref. [12] (page 123), the Lorentz transformation The distance of the observer from the Black Hole is x, the star is falling into the Black Hole at the speed of light v = c, time is t, the distance of the star from the Black Hole seen by the observer is xct, the distance of the star from the Black Hole calculated with the principal of relativity is x' Therefore the real distance of the star from the Black Hole is infinite, and the time has stopped, and the star cannot fall into the Black Hole at any time.The speed of the star cannot be higher than c because otherwise Figure 11.A star is falling into the Black Hole.The speed of the star is v, time of the observer is t, the distance of the star from the observer is vt, and the distance of the Black Hole from the observer is x.The distance of the Black Hole from the star as seen at the star is x', and the time at the star is t'.

Conclusions
In Figure 12, a star is falling into the Black Hole.In the falling movement, the change of the kinetic energy is equal to the work that is done by the force of gravity.The first calculation is in the three-dimensional gravitational field of our ( )( ) The second calculation is performed in the four-dimensional gravitational field of the four-dimensional Universe ( ) ( ) The speed distribution curves of the galaxy NGC 3198 have been presented in Ref. [2].The speed distribution curve of the galactic halo in that publication  10 20 in Figure 9 produces the gravity field with a maximum speed of rotation 11500 km/s, and it is enough to create the quasar.The fact that a quasar ejects matter along its rotational axis is proof that the quasar is not a Black Hole in our three-dimensional universe, but rather, as suggested by its location, exists in the fourth dimension.As it is seen in the Lorentz transformation above, the star falling into the Black Hole does not reach the Black Hole, but the observer sees that the falling stops before the Black Hole.Therefore the matter of the Black Hole is not three-dimensional matter, but it is four-dimensional matter.
The first calculation continues.The centrifugal force is equal to the gravitational force in the three-dimensional gravitational field.

Justification
1) The original Black Hole theory that shifting the real Black Hole of the galaxy NGC 3198 into our three-dimensional Universe was not true.The most massive Black Hole of our Universe was not massive enough for that theory.
However, there is a right kind of Black Hole for the quasar TON 618, but that Black Hole is in the four-dimensional Universe.That can explain the fact that matter can escape from the gravitation force of quasar.
2) A common belief has been that the mysterious missing dark matter could A. Rahikainen DOI: 10.4236/wjm.2023.135006123 World Journal of Mechanics be a halo structure around the galaxy.But it cannot be a halo structure because that kind of structure does not rotate the galaxy.That can be inferred from Equation (1).To be able to rotate the galaxy the dark matter must be on the galaxy's rotation axis, or near it.But the mass which is many times the mass of the whole galaxy would be a Black Hole, and it would destroy the galaxy.Therefore it cannot be a solution to this problem.The only option is that the mysterious missing dark matter is located out of our three-dimensional Universe.
Furthermore, the theories of Refs.[6] and [7] were proven to be true, and they also have an impact on this study.The following is presented the progress of the galaxy rotation hypothesis.This hypothesis states that the major gravitational force of the galaxy rotation is due to the four-dimensional mass which is the Black Hole of this study.
In Figure 13, the progress of the research and testing the hypothesis is presented in the same manner as in Karl Poppers's book [13].The first step, the hypothesis, is that the major gravitational field which rotates the galaxy is due to a dark fourth-dimensional matter M which is located at the galaxy's fourth-dimensional rotation axis.
The second step is the derivation of the equations.This phase of proceeding involves the derivation of mathematics of the galaxy rotation.The speed distribution curve v M of the four-dimensional mass M, Equation ( 11) and ( 12), has been calculated by using two pairs of rotational radius and speed values which are approximately the same as in Ref. [2] the speed distributions curves of the galactic halo of the galaxy NGC 3198.
The third step is the test prediction which is that the speed distribution curve of galactic halo in Ref. [2] corresponds to the speed distribution curve v M of four-dimensional mass of this study.
Figure 13.The progress of testing the hypotheses of the fourth-dimensional mass is presented by using the method of Karl Popper, Ref. [13].

The rotational speed distribution curve v M is calculated with Equation (11) by using the values of the mass M = 80 × 10 61 kg and its distance from the center of galaxy X' = 8.8 × 10 20 m, and it is the best fitting of Equation (11) to the component of halo speed distribution of the galaxy NGC 3198, Ref. [2].The maximum value of the speed distribution curve is v M = 131 km/s at the radius R = 8.8 × 10 20 m (29.2 kpc), and it is about the same as the maximum radius of the galaxy NGC

probable is that the path of motion of the star falling into the Black Hole is rotation about it.The extreme gravitation of the Black Hole accelerates the star near the speed of light, and the falling into the Black Hole slows down.

4236/wjm.2023.135006122 World Journal of Mechanics corresponds to the speed distribution curve v M of the four-dimensional mass of this study.This speed distribution curve is in Figure 8, and it is produced by the Black Hole M = 80 × 10 61 kg, X' = 8.8 × 10 20 m in the four-dimensional Universe.In this study, this Black Hole has been shifted toward our three-dimensional Universe, and at the distance X' = 0 the radius of this theoretical Black Hole is 7.7 × 10 17 m.According to the first calculation in the three-dimensional gravity, this theoretical Black Hole radius is resulted from the mass 5.2 × 10 44 kg.It can be compared with the real masses which have been found in our three-dimensional Universe.The most massive Black Hole is the quasar TON 618 with a mass 66 billion times greater than our Sun, and its mass is 66 × 10 9 × 2 × 10 30 kg = 13.2 × 10 40 .The first calculation yielded the mass for the theoretical Black Hole 5.2 × 10 44 kg and therefore the Black Hole of this mass is not in our threedimensional Universe.The theoretical Black Hole M = 80 × 10 61 kg, X' = 0.1 × for the four-dimensional gravity yielded the mass of the Black Hole M = 80 × 10 61 kg for the direct falling into the Black Hole which is the same value that has been in the rotational speed curves indicating the rotational falling into the Black Hole.Therefore, it can be concluded that the Black Hole of the four-dimensional matter is real.The first calculation for the threedimensional gravity yielded the mass of the Black Hole for the direct falling into the Black Hole M = 5.2 × 10 44 kg, and in the rotational falling into the Black Hole 10.4 × 10 44 kg.Therefore, it can be concluded that the Black Hole of three-dimensional mass is not real.
