Weak equivalence principle (the bodies are gravitating equally per inertial mass irrespective of the chemical composition) was confirmed for barionic matter with very high accuracy. However, a priory it is not clear, how to check weak equivalence principle for the mixture of barionic and non-barionic matter (light is inside the ordinary matter). For example, how fast would the sphere full of photons fall in the Earth gravity field? The experiment is not possible on Earth. However, such verification is possible for stars using the observational data on binary stars. In this article the analysis of the mass-luminosity was made for similar stars forming binary versus different stars forming binary and the slopes were found the same with accuracy of 6%. That would be the accuracy of confirmation of the equivalence principle for non-barionic matter (actually a mixture of barionic and non-barionic matter with around 0.14% of non-barionic matter ratio). While some violations of weak equivalence principle are still possible (the idea of strong gravitation of slow light) the scale of such violations is clearly well below the level expected for explanation of dark matter.

In recent publications we have proposed a quantitatively successful model for the origin of baryons, which should condense from a state at 3.71 GeV energy. From the analysis of Cosmic Rays protons data we conclude that such level should provide a measure also of the temperature at protons formation ( the origin of material Universe?), 4.3x10^13 K.

This work quantitatively deals with the fundamental issue of the origin of particles. By focusing initially on the relation between mass and magnetic moments for baryons, we then show that a wealth of experimental data, including the form of the observed flux profiles of cosmic rays protons can be consistently analyzed together if one takes as the starting point of the model that these particles condense from a vacuum, in the form of loops of charge. This brings back the long standing issue of whether particles should strictly be treated theoretically as point-like objects, or otherwise might have an intrinsic motion formally accounted for, which might be related to an effective finite size. Such issue arises in the socalled zitterbewegung solution of the point-like particle´s Dirac equation, which introduces the intrinsic motion of a “point” electron in the center of mass frame. The present treatment also applies the Dirac equation, and we obtain regularized loop-like solutions for the fields representing embryonic baryons. The fundamental “proton state” is taken as a substrate, as proposed by Barut many years ago. A loop can be regarded as a particle “embryo” and is a sizeable ( wavepacket) rather than a point-like object, tenths of a femtometer big when detached from the vacuum parent state. Such vacuum state is predicted as 2.7 GeV above the proton rest mass, which is consistent with the average protons energy in the energy profile of interstellar cosmic rays. According to statistical mechanics, this characterizes U0 =3.71 GeV as the environment equilibrium energy in which protons were formed(big-bang conditions?). Other features of such energy profile can readily be understood from the present analysis.

Comments: 10 Pages. 15 figures (The paper was submitted to one of the most prestigious astronomy journals. Reviewer's Report: “The author has presented a novel interpretation of the redshift-distance relationship of observed supernovae”)
The comparison of redshift-distance relationship for high and low-redshift supernovae has revealed the surprising transition of Universe’s expansion from deceleration to acceleration. As compared to local supernovae, remote supernovae are further away than expected. The expansion rate obtained for local supernovae is higher with low redshifts as compared to the expansion rate obtained for remote supernovae with high redshifts. Since observed redshifts provide an estimate of recession velocities in order to determine the expansion rate (km/s/Mpc) of the local and the remote Universe, therefore, it is very disturbing to find that low recession velocities indicate acceleration (faster rate of expansion), whereas high recession velocities indicate deceleration (slower rate of expansion). In this paper I unravel an undiscovered aspect that perfectly mimics cosmic acceleration. I show in this paper that remote structures began expanding into the Universe before the expansion got initiated for the local structures, for this reason, remote structures are not only further away than expected, but they also happen to yield a slower rate of expansion as compared to the expansion rate obtained for the local structures. The analysis is based on the redshift-distance relationship plotted for 580 type Ia supernovae from the Supernova Cosmology Project, 7 additional high-redshift type Ia supernovae discovered through the Advanced Camera for Surveys on the Hubble Space Telescope from the Great Observatories Origins Deep Survey Treasury program, and 1 additional very high-redshift type Ia supernova discovered with Wide Field and Planetary Camera 2 on the Hubble Space Telescope. The results obtained by the High-Z Supernova Search Team through observations of type Ia supernovae have also been analysed.

Here, we speculate on the causes of negative parallaxes of stars. We first summarize the concepts of refractional and gravitational lens, and we highlight the similarities between the two. We then analyze the relation between negative parallaxes and temperature of stars, and negative parallaxes and distance of stars. We observe that warmer and more distant stars show a larger number of negative parallaxes, with respect to colder and closer stars, respectively. Is refraction of light through a medium of astronomical bodies the cause of the observed stars parallaxes ? And moreover, could these astronomical bodies explain dark matter?

The cosmic censorship hypothesis has not been directly verified, and some physicists also question the validity of the cosmological censorship hypothesis. Through theoretical prediction, it pointed out that the existence of naked singularities is possible.This article puts forward a point that, under the quantum gravity equation, although there is no concept of wormholes, the chronology protection conjecture may not be true.

A close inspection of Zwicky's seminal papers on the dynamics of galaxy clusters reveals that the discrepancy discovered between the dynamical mass and the luminous mass of clusters has been widely overestimated in 1933 as a consequence of several factors, among which the excessive value of the Hubble constant $H_0$, then believed to be about seven times higher than today's average estimate. Taking account, in addition, of our present knowledge of classical dark matter inside galaxies, the contradiction can be reduced by a large factor. To explain the rather small remaining discrepancy of the order of 5, instead of appealing to a hypothetic exotic dark matter, the possibility of a inhomogeneous gravity is suggested. This is consistent with the ``cosmic tapestry" found in the eighties by De Lapparent and her co-authors, showing that the cosmos is highly inhomogeneous at large scale. A possible foundation for inhomogeneous gravitation is the universally discredited ancient theory of Fatio de Duillier and Lesage on pushing gravity, possibly revised to avoid the main criticisms which led to its oblivion. This model incidentally opens the window towards a completely non-standard representation of cosmos, and more basically calls to develop fundamental investigation to find the origin of the large scale inhomogeneity in the distribution of luminous matter.

Using stellar metamorphosis we can figure out what TOI-849b really is. Is it a remnant planetary core in the fictional hot Neptunian Desert, or a normal ocean world? It is up for the readers to decide. The main paper is archived here as proof: http://archive.is/FOb17 and the interpretation by the media is here: http://archive.is/hCX2l.

Comments: 41 Pages. Improved analysis to cover non-spherically symmetric systems
We put forward the conjecture that the energy scale can vary from location to location. This simple idea is all that we need to explain those astronomical situations where dark matter is assumed to exist. So, without invoking dark matter, or postulating the existence of exotic particles, or changing the laws of gravity, we can explain: galaxy rotation curves; the high velocities of galaxies in clusters; collisions between clusters of galaxies; gravitational lensing by galaxy clusters; the fluctuations in the cosmic microwave background; physical cosmology; the growth of structure. If variations of the energy scale exist, then we can make a series of predictions, many of which can be tested now. We have nothing to say about dark energy.

All solar science is based upon the premise that the activity of the Sun is not influenced by anything that is outside of the Sun. That premise is based upon the theories presented by Eddington and carried forward to the present. Eddington's knowledge about electromagnetic waves was limited to what was known about them when he developed his theories It is now known that there are EM waves with periods that exceed one second in duration and their frequencies are being presented as 10s fractions of a second. This means our current EM frequency scale is nonlinear. An error was made some two centuries ago when the duration of the second was selected to present EM frequencies. Solar activity is being incorrectly interpreted because of the nonlinear EM frequency scale scale implies EM waves with frequencies below 1 Hz do not exist. Physical law equations that use frequency directly or indirectly, using the speed of light (c), have a validity issue because of the frequency issue.
