It is hypothesized that the characteristic acceleration scale (gc) seen in galaxies
can be interpreted as the effect of a subatomic structure of the vacuum space. As a consequence, the characteristic mass surface density associated with gc defines the breakdown of classical gravity for gravitationally bound systems beyond a baryonic mass scale of ≈1.8 104 Msun. Both characteristic scales can be expressed in terms of two number constants, the natural constants GNewton, me, c and the reduced Planck constant hbar.

Calculations show that the sensitivity of common gravimeters is sufficient to measure GW in wide frequency range around 0.1 Hz. Initial evaluations have confirmed that it is possible to extract the coordinates and frequency drift of known binary star systems with good accuracy from multi-year data records of gravimeters distributed around the world. This opens the possibility of an Earth-based search for continuous GW several years before LISA.

Superconducting gravimeters respond to deformations of the test body Earth by gravitational waves. The frequencies of continuous gravitational waves are identified by means of selective integration of long-term data. The modified superhet method is a suitable method to determine the direction of the GW source. The measured frequency deviation of the phase modulation exceeds the upper limit allowed by the Doppler effect. This problem can be can be solved by assuming that the propagation velocity of GW is lower than the speed of light.

Split Property of the black hole information paradox, the problem of the loss of information
from black holes, are discussed by means of a novel approach based on the evolution of a quantum
scalar field in a background that contains a black hole. We show that the paradox cannot be
resolved by assuming split property. A new definition of the area of the horizon is proposed.
The horizon area is an observable, and the value of this observable for a black hole is related to
its entropy. The entropy of a black hole has been derived. The loss of information from a black
hole is a consequence of the loss of entropy. We also calculated the Hawking temperature and
some thermodynamic entities of black holes.

Backlight scattering in a single event provides an account of the nearly uniform full images of all the planets and their moons. The uniformity of the full moon image has been discussed in terms of multi-event scattering. Similar images of other bodies have not been discussed. Multi-event scattering must lead to Lambert's Cosine scattering law, however, there are no object images that comply with it. Single event scattering is automatically coherent since a single electromagnetic source wave stimulates all the scattering dipoles. The coherence provides an account for the "Opposition Effect", enhancement of 180 degrees backscattering, by constructive interference. Opposition enhancement has been considered so far as a separate effect from image uniformity.
The coherence of single event scattering may enable separation from non-coherent scattering noise by applying interference methods so that objects would be observed with better resolution or at a higher distance. Removal of incoherent noise may also enable deeper image observation within a scattering medium, such as biological tissues.

Spiral galaxies pose two profound conundrums that the current cosmology has no clear answers to. I claim that the observations of the velocity curve flattening and the spiral shape of galaxies emerge from the velocity of a star in a galaxy. The star velocity is the superposition of velocities exerted on a star by the Pivot, the black hole at the center of the galaxy, and the distributed mass of the galaxy.

The main goal of this study was to find feasible methods and strategies for the deflection of large asteroids in the diameter range of 5 to 200 km. For the deflection of asteroids in the 50-200 km range only one feasible way was found, which is an indirect but extremely powerful technique ! (see Deflection-Strategy_3).
A first assessment of our ability to deflect an asteroid of a certain diameter was carried out. It was considered that only existing and proven technology and a powerful direct deflection method (a nuclear explosion on or close to the surface of the asteroid) would be used for this task. The result of this assessment is presented in the form of a table. This table shows the minimum amount of NED's (Nuclear Explosive Devices) which is required for the deflection of an asteroid with a given diameter, so that it just misses our planet Earth. Here it was considered that either the maximum explosive yield (Deflection-Strategy_1) or only a small defined fraction of the explosive yield (Deflection-Strategy_2) of the used NED's is transformed in work (kinetic energy) which is usable for a direct change of the trajectory of the asteroid at a given distance to Earth (of either 250 or 500 million km). For the deflection of asteroids in the 50-200 km range only one feasible way was found, which is an indirect but extremely powerful technique ! see Deflection-Strategy_3. This indirect Deflection-Strategy_3 makes use of the Deflection Strategies 1 or 2.
There is clear statistical evidence for a 62-million-year-cycle in bio-diversity (fossil diversity) on Earth. Currently we live at the end of the declining phase of such a 62-Myr cycle. The declining phase of this cycle must be called an extinction period ! If we look at the diagram which shows the bio-(fossil)-diversity on Earth (Diagram-1), it is evident that there are abrupt and deep cuts into the bio-diversity within each marked extinction period ! Possible cause of this bio-(fossil)-diversity cycle (or extinction cycle) could be a 20 Myr long Big-Impact-Period every 62 +/- 3 Myr, which may be caused either by a periodic crossing of the galactic plane all 66+/-6 Myr, by our Solar System, or by a periodic behavior of our sun (e.g. sharp rises and drops in the Solar-Wind-Flow and Flare Activity), which may disturb the asteroid- and comet orbits in our solar-system.

Quasars are very distant quasi-stellar objects that
appear like stars, thus their name. They may all
be active galaxy cores. Only a few are visible and
identifiable to amateur astronomers, even though
very expensive professional instruments can detect
large numbers. These weird deep sky objects can
be formidable for amateurs to both see and identify,
but the quest is uniquely rewarding. Here is a brief
introduction from somebody who has done it.

The COBE, WMAP, and Planck data analyses exhibit that the CMB restframe can be seen as a fundamental, absolute space, the CMB-space.
All Earth flyby radio Doppler data anomalies can be resolved by applying the general, classical Doppler formula (CMB-Doppler formula) of first order for two-way signals between earthbound Deep Space Network stations and a spacecraft during an Earth flyby.
For that purpose, the annually varying absolute velocity vector ue of Earth is used, derived from the absolute velocity vector of the solar system barycenter, usun, magnitude usun = 369.82±0.11km s-1, in direction of constellation Crater, near Leo.
Together with the relative, asymptotic inbound and outbound velocity vectors vin and vout in the equatorial frame, we obtain the absolute inbound and outbound velocity vectors uin and uout in the equatorial frame.
The relative, asymptotic inbound and outbound velocities are actually equal in magnitude (vin = vout), while the magnitudes of the absolute inbound and outbound velocities of a spacecraft are in general different (uin ≠ uout), leading to the apparent anomaly.
Thus the use of the CMB-Doppler formula explains the so far as residual considered positive or negative differences in energy. The measured, different absolute velocities in the CMB rest frame explain the supposed radar ranging data residuals as well.

Oumuamua was the first interstellar object observed to pass through the solar system. It did not follow the expected hyperbolic path, as if the pull of the Sun’s gravity was less than expected. Off-gassing normally present in comets was not observed. A modified gravity hypothesis — cyclic gravity and cosmology (CGC) — is proposed here to explain this motion. This hypothesis also would entail a greatly simplified and cyclic cosmology, potentially resolving the Hubble tension controversy.

There are no true images that comply with Lambert's cosine light scattering law. There is no reasonable explanation to the uniform appearance of the full moon image. There is no explanation at all of the uniform appearance of the "blue marble" the full earth image.

The dynamic space is structured by three fundamental elements, namely length, elementary electric charges (units) and forces. A spherical deformity of the space has occurred, which has created an equality of the peripheral and radial cohesive forces (Universal symmetry). Close to the Universe center this equality is breached, thus causing the Genesis of the primary form of matter and the Universal antigravity force, whereby the Hubble’s Law is proved. At the periphery of the Universe the dynamic formation of particles is turned back to the dynamic space and the vacuums
of their cores end up into the vacuum-nonexistence, thus resulting the upgrading of
entropy of the Universe. Actually, by the dissolution of the space deformations, the oriented forces (high entropy) are restored in the form of space cohesive forces (zero entropy). However, collisions of the charged particles take place onto the elastic membrane at the periphery of the Universe. The above membrane consequently
oscillates and causes the acceleration of a residue of the charged particles towards the interior of the Universe and, since the charged particles arrive at the periphery of the Universe at the same centrifugal speed and are degraded by the same mechanism, they provoke a weak and constant Cosmic background radiation.
