The method for finding the signal from the gravitational wave in the interferometrical data of the LIGO observatory is demonstrated on the test example of the gravitational event GW150914. The method is based on the use of correlation analysis, reasoning from the fact that the shape of the signal to be found is known, as well on the use of computational statistics methods. The developed method was applied for the search for signals in the LIGO data for a 32 seconds time-frame inside standard data block of 16 s prior and 16 s after the GW150914 event. The performance of the method and its advantages for the analysis of signals in a noise are shown. The paper includes analysis of possibility of the existence of other useful signals in the noise signal where the chirp of the event GW150914 was detected.

Michelson-Morley experiment and Sagnac effect were aimed to solve a long debated and crucial question in physics - does the aether exist? But the experiments resulted in two contradictory results —the Michelson-Morley experiment finding was that there is no aether whereas Sagnac showed that the aether exists. Current Physics has no clear answer to this basic and profound conundrum.

The binary star system J0651 is expected to be be one of the brightest sources of gravitational waves in our galaxy. Despite its known frequency, the radiation could not be detected so far. A new method eliminates the strong phase modulation caused by the Earth's orbit and drastically reduces the bandwidth. Therefore, the GW may be identified in the records of numerous superconducting gravimeters. The determined parameters of GW agree well with the results of previous observations in the optical domain and the predictions of relativity.

Using the photon universe model, as an alternative to the "missing mass" models (dark matter, MOND, etc), a theoretical derivation of the rotation curves of galaxies is proposed.

Using the model of the universe of photons, as an alternative to the models of the "missing mass" (dark matter, MOND, etc.), a possible interpretation of the rotation curve of galaxies is presented by introducing two parameters: the critical mass and the limit radius for a galaxy.

There is no singularity point in a physical black hole. A singularity point was derived from solving GR equations. However, it is merely a mathematical construct that does not exist in reality.

Physics lacks a confirmed description of dark matter, has yet to develop an adequate understanding of dark energy, and includes unverified conjectures regarding new elementary particles. This essay features modeling that addresses those problems and explains otherwise unexplained data. Our modeling starts from five bases — multipole expansions for the electromagnetic and gravitational fields associated with an object, the list of known elementary particles, some aspects of mathematics for isotropic harmonic oscillators, concordance cosmology, and a conjecture that the universe includes six isomers of most elementary particles. The multipole expansions — which have use in conjunction with Newtonian kinematics modeling, special relativity, and general relativity — lead to a catalog of kinematics properties such as charge, magnetic moment, mass, and repulsive gravitational pressure. The multipole expansions also point to all known elementary particles, some properties of those particles, and properties of some would-be elementary bosons and elementary fermions. The harmonic-oscillator mathematics points to Gauge symmetries regarding some elementary bosons. The would-be elementary fermions lack charge and would measure as dark matter. The conjecture regarding six isomers of most elementary particles rounds out and dominates our specification for dark matter. Five of the isomers form the basis for most dark matter. Our modeling explains ranges of observed ratios of dark matter effects to ordinary matter effects — for the universe, galaxy clusters, two sets of galaxies observed at high redshifts, three sets of galaxies observed at modest redshifts, and one type of depletion of cosmic microwave background radiation. Our description of repulsive gravitational pressure points toward resolution for tensions — between data and modeling — regarding the recent rate of expansion of the universe, resolution for possible tensions regarding large-scale clumping, and resolution for possible tensions regarding interactions between neighboring galaxies. Our work regarding gravity, dark matter, and elementary particles suggests characterizations for eras that might precede the inflationary epoch, a mechanism that might have produced baryon asymmetry, mechanisms that govern the rate of expansion of the universe, and insight about galaxy formation and evolution.

25 years ago, weak permanent oscillations were discovered in the records of gravimeters, which are not excited by earthquakes and are also not natural resonances of the earth. Proposed causes like wind and ocean waves are ruled out because of their unreliability. The oscillation at 836.69~$mu$Hz exhibits most typical modulations expected for gravitational waves. Their frequency stability can also explain the surprising, previously unknown phase coherence discovered in the records of eight gravimeters. The gravitational waves emitted by the countless binary star systems in our galaxy are probably the cause of the strikingly strong background noise of gravimeters.
