3. The Lower Limit of Cosmological Expansion or Scale Drift
The lower limit of cosmological expansion postulated by Einstein and Straus [1] is found today by comparing (difference-formation) the respective potential of a gravitating mass with the potential of cosmological expansion. Here, a substantial incorrectness is committed: The potential of a gravitational mass leads to a change in the relative velocities of objects in the area of influence. In contrast, cosmological expansion does not result in a relative velocity according to STR but something else. So two different phenomena are being compared. Such a comparison is inadmissible ! Through this inadmissible comparison, one comes to the assumption: Gravitationally bound objects are not subject to cosmological expansion. We consider this assumption to be incorrect. With a few exceptions (e.g. [24,26–28]), it is widely agreed that gravitationally bound objects do not expand cosmologically. On the other hand, despite the redshift of the Virgo cluster, i.e. cosmological recession, the so-called Virgo infall exists [4]. Besides this obvious contradiction, expansion effects of the size of the Hubble constant are repeatedly found in much smaller areas. As a result of different assumptions about the lower limit of cosmological expansion, we hold our own view:
The lower limit is not formed by the Einstein/Straus relationship, nor by comparing the potentials of gravitation and expansion. We assume that the lower limit of the cosmological expansion is found by comparing the effects of the gravitational potential with the effects of the electromagnetic potential. If one compares the shape of planets with the shape of small planetoids or even smaller objects, it becomes apparent that the shapes are differently shaped or dominated. Low-mass objects, such as small asteroids, are obviously not influenced in their expansion behaviour and shape by their own gravity. The inner binding is not primarily due to gravity, as is the case with the earth, moon and planets, but due to other forces (electromagnetism). We conclude that the lower expansion limit is in the transition region. With increasing mass, the shapes become rounder and more shaped by gravity. Smaller and lower-mass objects show crystalline and molecular shapes. The shape-forming properties are less or not dominated by gravity. For example, overhanging parts of a construction (bridges, jibs on cranes) do not obey gravity. A 1 m slab of rock does not become a sphere in free space due to its own gravity. The internal electromagnetic forces are stronger than the gravitational forces. Although gravity determines the structure of space, this plays a subordinate role in this case. Consequently, monolithic rigid blocks expand less or not unless they exceed a limiting size/mass ratio. Molecular / crystalline forces dominate the shape of the rock slab. However, debris piles of the same size can expand. The inner spatial properties determined by gravity are subordinate to the inner electromagnetic properties when the mass is small. Cosmological expansion or scale drift is a property of gravitationally dominated space. This property is not relevant for low mass. Due to this subordination, objects of our daily environment and smaller ones (e.g. small asteroids, seconds pendulums and caesium atoms) do not participate in the cosmological expansion or scale drift. The relation (1) used below loses its meaning. Although the Earth as a whole is subject to cosmological scale drift (expansion) according to [7], this does not apply to continents of a few kilometres in thickness (thickness) (according to [5] and
Table 1, line 8). Even small asteroids obviously do not expand. The acceleration of rotation for small asteroids can therefore occur not only through a change in mass or YORP effect, but also through shrinkage with numerically constant radius and angular momentum. The seconds pendulum does not expand like the earth's radius, the moon's orbit or the distance and size of extragalactic objects. The spatial and temporal size of the light-second (299 792.458 km) therefore gradually becomes smaller (shorter) compared to these "units of measurement", despite numerical constancy. Because small objects are not gravitationally dominated, they shrink compared to gravitationally dominated objects at constant angular momentum. The system of measurement with the SI second shrinks compared to the UT second [20]. The distance between the Earth and the Moon is determined by gravity and is subject to expansion. The expansion concerns - as with the earth's radius - the size of the units of measurement, not their number !
Objects or phenomena bound by their own gravity are listed in
Table 1. According to standard theory, these should not show any cosmological expansion.
5. Measured Values Versus Standard Theory
The occurrence of the rate ~ 3 × 10
-18 s
-1 in all ranges mentioned in
Table 1 from the Earth's radius to the astronomical horizon is remarkable. In these two extreme cases, relative velocities are excluded as the cause of the existing rate. For the Earth's radius, the exclusion is due to measurement results by X. Wu et al [7] and for the universe because recession velocities at large distances are greater than the speed of light (v>c). If there is a common cause, the relative velocities are also to be rejected for intermediate values. This is true for lunar orbit and solar orbit in the Galaxy, among others. If no relative velocities occur as a result of cosmological expansion, the corresponding distances are numerically constant despite this expansion. The cosmological expansion manifests itself as recession speed or scale drift. For the distance of the earth's radius it is approx. 0.05 cm / a [5]. For the lunar orbit, the result is approx. 2.9 - 3.9 cm / a, depending on the type of measurement [8–10]. The distance of the solar orbit in the Galaxy results in a recession velocity of about 4×10
15 km / orbit (~420 Ly/orbit) or 18×10
6 km / a and for the Andromeda Nebula it is about 50 km / s. However, the recession velocity of the Andromeda Nebula is superimposed by a larger, opposite relative velocity. The values given are obtained by using the rate a=2.5×10
-18 s
-1 and relation (1). The values obtained from this agree with the measured values (if measurable).
(a = expansion rate≡ recession rate, D r = distance difference or recession value, t = period, r = distance)
The value α ≅ 2.5 ×10-18s-1 is found several times in the solar system, but also in other gravity-bound systems. a should not be confused with the cosmological scaling factor a.
Below are some examples of the occurrence of the cosmological expansion rate in gravitationally bound objects. Further examples are partly included in
Table 1.
5.1. Inner Core of the Earth
In 1962, S.K. Runcorn gave a growth rate of 243 km / 109 years for the inner core of the Earth [16]. That is 0.0125 cm per year and radius of the Earth's inner core. With relation (1), this results in an expansion rate or drift rate of ~ 3×10-18s-1 and thus approximately the cosmological expansion rate or Hubble constant. The "surface" of the inner core of the Earth moves away from the centre of the Earth proportionally to the surface of the Earth, the distance to the Moon and the extragalactic objects because the same rate is present for all of them. More recent publications mostly also assume an expanding inner core of the Earth of the same order of magnitude.
5.2. Earth Radius
X.Wu et al investigate the expansion behaviour of the Earth in [7]. Among other things, the relative velocity between the centre of mass and the Earth's surface was measured. It was concluded that there was serious evidence of expansion of the Earth's radius. However, the measurements using ITRF 2008 + Grace + OMCT + ECCO showed maximum values ~ 0.1 mm/a or smaller, i.e. insignificant or non-existent at present. Here the found scale drift or origin drift is of interest. Their size is not particularly certain due to insufficient data and, depending on the parameters used, amounts to approx. 0.5 mm / year for the earth's radius. We set the corresponding values equal and get : 0.05 cm / (31.56×106s 6370 × 105 cm) = 2.5 ×10-18 s-1.
The cosmological expansion rate and the scale drift rate of the Earth have the same value.
The deceleration rate of the Earth's rotation is of approximately the same value. According to
Section 6, other authors ([23,27]) and we assume tidal friction to be only part of the cause of the rotational lag. The rotational deceleration should lead to the pirouette effect if the earth mass is approximately constant and the moment of inertia is valid. The Earth's radius should expand according to the rotational deceleration. The radius difference (∆r) results as (2).
(
Δr =radius difference (cm), r =Earth radius (cm), t =rotation time (s), Δt =Length of day(LoD) change(s/100 a)
Δr = 6371 × 105 [ ( 1+ 0.0016 / 86400 )0.5 -1 ] = 5.9 cm / cy = 0.059 cm / a.
The value 0.0016 / 86400 refers to the lengthening of the day per 100 years.
The value of the radius difference corresponds to the cosmological expansion rate. An expansion of the numerical Earth radius is therefore not present according to
Section 2. This fact was confirmed in [7]. The increase of the value by 0.059 cm / ( a × r ) results from the scale drift at numerically constant earth radius published in [7]. The value of scale drift of approx. 0.5 mm / year given in [7] is therefore acceptable. If it is a continuous drift, smaller drift values are obtained for smaller distances and periods and larger drift values for larger distances and periods. The expansion of the lunar orbit and other distances can also be explained by scale drift.
5.3. Area Ratio Continents / Oceans
Including the continental shelves in oceanic shelf areas down to a depth of ~ 200 m, the total continental area on Earth is approx. 177 × 106 km2. This area would cover a globe of 3750 km radius almost without a gap. With a radius of r = 6370 km, 333 × 106 km2 remain for the oceanic crust. The difference in the radii is ∆r = 2620 km. The age of the oceanic crust is less than 200 × 106 years, while the age of the continents is about 4 × 109 years (t = 1.26 × 1017 s). Using relation (1) with the above values for r, t and Dr, the result for the Earth is an expansion rate of a = 3,265 × 10-18 s-1.
For comparison
If we assume the age of the continental crust to be 4 × 109 years and the age of the world to be 13.7×109 years, this is 29.2 %. Since a relatively constant expansion rate of the universe can be expected for 4 ×109 years, a cosmological expansion of 29.2 % has occurred during this period. If this is true for the Earth according to section 5.2, the Earth was 29.2 % smaller when continental crust was formed than it is today. The earth's radius was 1860 km smaller at that time. According to today's scale, r = 6370-1860 = 4510 km. Relation (1) yields an expansion rate or drift rate of a = 2.313 × 10-18 s-1. The difference to the value of a = 3.265 × 10-18 s-1 determined above may be due to incorrect crust age or area ratio but also to scale drift.
The expansion rate obtained is close to the cosmological expansion rate for both methods.
5.4. Lunar Distance
The distance to the moon is about 60 times greater than the radius of the earth. The drift value or recession value is 60 times greater than expected for the Earth's radius. The scale drift is then 3 cm per year and orbital radius of the moon. With relation (1) and the cosmological expansion rate a ( 2.4 × 10-18 s-1 ) one obtains the recession value or drift value ∆r » 2.9 cm/a. This is in agreement with the drift value of the Earth's radius [7] and the values measured during solar eclipses. Sediment data also indicate an expansion or drift of 2.9 ± 0.6 cm/year [8]. Measurements with LLR give the larger value 3.82 ± 0.07 cm/a (3,15 × 10-18 s-1 ). However, it is likely that a relative velocity (e.g. from tidal friction) and the recession velocity or scale drift complement each other because the moon still exists (see also section 6). This assumption is now supported by various authors [28]. In the case of the Andromeda Nebula, a (negative) relative velocity must also be added to the recessional velocity.
5.5. Pioneer Anomaly
The Pioneer anomaly describes an anomalous delay of the Pioneer X and XI space probes. The delay value is 8.74×10-8 cm/s2 [15]. It results from a frequency shift of the radio signals assuming the Doppler effect. Dividing the deceleration value by the speed of light yields a deceleration rate of 2.91×10-18s-1. This value agrees exactly with the Earth's rotational deceleration and corresponds approximately to the Hubble parameter (!). Shortly after the discovery of the pioneer anomaly, cosmological expansion was considered a possible cause. This possibility was rejected by cosmology [22]. The argumentation: Cosmological expansion only leads to redshift and also only outside gravitationally bound systems. We contradict these assumptions in sections 2 and 3. If, contrary to standard theory, the universe is also expanding in the solar system, the units of measurement of space (metre, light year, second etc) were smaller at the time of the probe launches than they are today. Due to the expanded units of measurement since the launch of the probes, the current measured distance is numerically smaller than expected. This manifests itself as a delay and a blue shift. With a numerically constant speed of light, the second was also shorter in the past. The time scale corresponds to the course of UT time defined by gravity. This deviates secularly from the electromagnetically defined SI time at a rate of 2.91×10-18 s-1.
5.6. Orbital Expansion of Saturn's Moon Titan
Measurements by the Cassini spacecraft show that the orbit of Saturn's moon Titan is expanding (or drifting) by 11.3 ± 2.0 cm/year. This value could be caused by tidal friction. However, without additional assumptions as described by V. Lainey et al. in [25], this value is clearly too large for normal tidal friction. However, according to F.R. Stephenson et al [23], the orbital expansion of our Earth's moon and other Saturnian moons measured by LLR is also too large to be caused by tidal friction. Taking into account the measured value and Titan's orbital radius of 1.22×1011 cm, the expansion rate is a = 11,3 cm × (31,56 × 106 s × 1,22 × 1011 cm) -1 = 2,93 × 10-18 s-1. It should be noted that the closeness to the cosmological expansion rate has already caused discussion [26].
5.7. Size Evolution of Galaxies
The effective radius of large galaxies decreases with increasing distance and the inner density and dynamics increase. There are a number of studies on this subject, e.g. in [6,12,21]. P.v.Dokkum et al [6] describe galaxies located at a distance of z ~ 2.2 (~ 10.7 × 10
9 Ly). We see these galaxies as they were after 20% of the present world age. The radii are apparently about 0.9 kpc, i.e. 20 % of the usual radius of galaxies of the same type and mass today. Such galaxies do not exist in today's nearby universe. An explanation other than expansion does not seem possible. Let us assume that today's galaxies began at this size and density. In this case, the expansion rate results from the difference of the radius per radius and the expansion time (1).
a = required expansion rate,Dr = difference between present radius (5) and emission radius (1), r = adequate present radius (5), t = distance in light time (SI-s).
This expansion rate corresponds to a Hubble constant of 73.2 (km / s) / Mpc. The objects are gravitationally bound objects. They expand according to the cosmological expansion. This contradicts standard cosmology. I.Trujillo makes a similar observation when he writes: "Consequently, the very dense nature of our objects at high z could reflect the much denser state of the universe at the time of their formation" [21]. We see that these studied objects exhibit the same effect and rate of expansion as observed today as scale drift on Earth (see above: Earth radius).
6. Conclusions
The multiple occurrence of the cosmic recession rate 2 - 3×10
-18 s
-1 in gravitationally bound systems suggests that the expansion of space is also present in full magnitude in these objects.
Section 2. shows that the expansion or recession is not a relative velocity in the sense of the STR. There is therefore no numerical change in distances due to the occurrence of this rate. The work of X Wu [7] and NASA confirms in the case of the Earth that the above rate is caused by scale drift and not by a relative velocity between the centre of the Earth and the surface. The recession rates listed in
Table 1 suggest that there is a common cause for the listed phenomena. The scale drift appears as an expansion or recession. The length of day (LoD) grows at approximately the same rate and accordingly with the same cause. An increase in the LoD due to tidal friction is assumed here in addition to scale drift. Tidal friction theory, however, demands a much faster increase in LoD (2.4 ms / cy) than observation allows (1.6-1.8 ms / cy) [23]. This points to deficiencies in the theory of tidal friction. In
Table 1, the LLR measurements with a ~ (3.15 ± 0.06) × 10
-18 s
-1 give the highest value for scale drift or recession near the Earth. We therefore assume that the difference to the Hubble constant is caused by tidal friction. Only this difference would then correspond to a relative velocity between the Earth and the Moon. The numerical distance of the moon in early times is then only insignificantly smaller than today. Destruction of the moon by the Earth's Roche limit is therefore not necessary.
If one assumes that cosmic recession is not a relative velocity corresponding to the STR and occurs in gravitationally bound objects,further consequential phenomena must have to occur or be present, for example:
1 According to paragraph 2, a relative velocity does not exist due to cosmological recession. Orbiting objects thus maintain their numerical distance from the centre of gravity despite this recession.The orbital speed and orbital radius of the earth remain numerically constant despite the expansion (recession) of about 11 m × a-1 × AU-1, as does the length of the year. With the numerically constant orbital radius, the orbital velocity also remains numerically constant despite recession. This is true for lunar and planetary orbits as well as for stars in galaxies. In the diagram (orbital radius versus orbital velocity), the level of the orbital velocity is approximately flat towards the outside. The flat course of the orbital velocities in galaxies [14] does not require dark matter. Modified Newtonian Dynamics (MOND) is also not required.
2 The Earth and the orbits of other gravitationally bound objects expand according to scale drift rate. However,the numerical radii remain constant, since relative velocities according to
Section 2 do not exist [7].
3 The Moon moves away from the Earth at approximately the same recession rate as by Hubble constant. We conclude that the measured recession is primarily not a relative velocity.
The measured value of the lunar recessions is about 3.8 cm/a. 2.9 cm/a of this obviously refers to the cosmological expansion or scale drift of the units of measurement. A relative velocity of 2.9 cm/a, i.e. a change in the numerical distance, therefore does not exist (analogous to the Earth's radius in [7]). Only the difference of 3.8 - 2.9 = 0.9 cm/a can be a relative velocity. This value corresponds better than the other two values to the expected tidal friction and requires no destruction of the Moon by the Earth's Roche limit at early times.
4 According to section 5.7. it can be assumed that radii and distances of spiral galaxies used to be smaller during cosmic expansion, but were numerically constant according to section 2. In the process, the outer regions of the galaxies move away from their centre faster than the regions near the centre. We observe an analogous situation with distance measurements of the Earth's radius and the Moon's orbit in relation to the Earth's centre of inertia at different times.
5 The continents and our everyday environment do not participate in the expansion or scale drift. These objects as well as e.g. small moons and planetoids are obviously dominated and shaped by electromagnetic forces and not by gravity (section 3).
6 The lower limit of the cosmic expansion is not removed. However, it is at a smaller distance than in the standard theory. The size of this distance is interesting for space travel (pioneer anomaly), geophysics (LoD), time determination (leap seconds) and other fields. This makes this value interesting for space travel (pioneer anomaly), geophysics (LoD), time determination (leap seconds) and other fields.
7 Using the brightness of supernovae, it was found that the Hubble constant was smaller at great distances (in space or time) than it is today. The cosmological recession velocity or scale drift has increased less per Mpc at great distances than in the near universe (there<70 km×s
-1×Mpc
-1). According to
Section 2, gravitationally defined dimensions (radii, distances, time periods) are subject to expansion or scale drift. The Hubble constant relates a recession velocity (km×s-1) to a distance (Mpc). The smaller Hubble constant determined for large distances refers to the smaller Mpc there. The expansion rate there therefore remains constant (≅ 2.4 ×10
-18 s
-1).This contradicts the increase in the Hubble constant due to dark energy.
8 The deceleration rate of the Earth's rotation is of close size to the expansion rate of the universe. The delay corresponds to a drift of the (SI) time scale. Since time and space have approximately the same scale drift rate (≅2.5 ×10
-18 s
-1), the numerical constancy of the speed of light is ensured. The galaxies mentioned in section 5.7. have a distance of about 10.7 × 10
9 Ly according to the current scale value. Since this distance is numerically constant according to section 2. and had smaller scale values at the beginning, the number of spatial and temporal distance units results in (3).
(Σ
= Sum of the past distance units since emission, n = number of distance units defined today, x1 = scale value of the first unit after emission (=1), xn = scale value of the unit in the observation (=5)).
The light that reached us was therefore not 10.7 × 109 years but 32.1 × 109 years on the way. If one observes objects whose distance is close to the world age, the light travel time is close to ×.
9 The value of the cosmological recession can be calculated with relation (1). For the distance Earth - Sun (AU), this results in a recession value of approx. 11 m × a
-1 × AU
-1. According to
Section 2, this recession velocity is not a relative velocity in the sense of the STR. The latter is not existing. X.Wu et al find in [7] that a relevant relative velocity of the distance earth centre - surface (earth radius) does not exist either. However, a scale drift corresponding to the expected recession speed was measured for the Earth (~ 0,5 mm × a
−1 × r
-1). This drift rate corresponds to the cosmological expansion rate.
The recession value of the AU of 0.15 m × a-1 × AU-1, determined in [29] is obviously a relative velocity with a cause other than cosmological expansion.The determined recession value of the AU of 0.15 m×a-1× AU-1 is obviously a relative velocity with a cause other than cosmological expansion. A decrease in the mass of the sun, for example, results in a low relative velocity of the increasing distance earth - sun (AU).
Objects bound by their own gravity are subject to cosmological expansion (scale drift), contrary to standard theory. This is not the case for other objects. The former include massive objects such as fixed stars, pulsars, Earth, galaxy clusters. Other objects include, for example, smaller, low-mass planetoids and moons (< 200 km), continents and objects in our environment.
Hilgenberg, Carey, Scalera and many others assume that the Earth is expanding. It seems that this assumption is partially justified. X.Wu et al. [7] and NASA confirm this assumption by stating : The measured number of units of the Earth's radius remains almost constant. However, the size of these units expands according to scale drift rate !
