Opis:
The article deals with the so called missing mass problem which during the last three decades has become one of the most serious difficulties in physics. There is some strong empirical evidence that the Universe contains not only matter that can be seen (by telescopes or radio telescopes) but the huge quantities of the unseen matter as well. The ordinary matter known to physics is but a small part of all matter the Universe is composed of. The missing mass is supposed to be in the form of the dark matter and the dark energy. In the paper the arguments in favor of the existence of these two entities are outlined, and some scientific as well as philosophical implications of the missing mass problem are discussed. It is argued that all the proposed solutions of this problem lead to serious changes in the scientific and philosophical worldview.

Opis:
This paper presents the real sense of the classical and quantum theory of gravitation as a component of the actual picture of the universe where the volume, as the size of the expanding universe, approaches infinity, while the total of material masses goes to zero. At present, these two standard theories describe the phenomenon of gravitation but do not explain the very mechanism and the cause of this process. This constant and real lack of information on that subject is consistent with natural laws and the same with the laws of physics, which were already experimentally determined by Werner Heisenberg in 1927. The paper also presents the causes of inability to explain up to the present the actual picture of the essence of the universe.

Opis:
One of the essential aspects of the dispute between scientific realism and anti-realism is the question of the ontological status of unobservable objects assumed by scientific theories and models. Scientific realism claims that these objects exist in the natural world, while anti-realism denies this. The missing mass problem is a good example of an issue that requires that this question be resolved. In cosmology, this problem is solved by assuming the presence of dark matter and dark energy. The difficulty, however, is that experience does not provide direct evidence for the existence of these two „substances.” In the first part of the article, the differences between scientific realism and anti-realism are discussed. In the second and third parts, the problem of the missing mass is presented (special attention is paid to the difficulties with the empirical confirmation of the existence of dark matter and dark energy). The fourth part of the article discusses the arguments of the supporters of half-realism, which is a kind of compromise between scientific realism and anti-realism.

Opis:
The paper describes the logical and at the same time the proper theory of the Newton’s law of universal gravitation in the universe. It presents the observed principles of “attraction” as a phenomenon of repulsion based on the difference of dark matter pressure. This paper proves in theory that the phenomenon of “gravitation”, as a phenomenon of attraction, does not exist (no mechanisms) and is mistakenly confused with the phenomenon of repulsion.

Equalized mass; complete total potential energy; dark matter/energy; missing mass
Opis:
In order to compare properties of celestial bodies regardless of their motions, their masses, which represent also their energy spent on resistance to forced motions, should be expressed with respect to the same (for all of them) material substance, such as water, for instance. Then their density of matter, which has been defined as the ratio of their actual mass/bulk to an equivalent mass of water, should also be taken into account even in the radial Newtonian law of gravitation. Such an equalized mass adheres to the Newton’s definition of “quantity of matter” as conjoined feature (i.e. product) of matter density and the bulk=mass of the body, even though he has never really operated on the notion so defined. The equalized mass conforms to the Einstein’s concept of mass as equivalent of energy, both of which vary with speed. Hence the product of equalized mass and density of matter can increase the radial gravitational force of very dense stars, easing the problem of the allegedly missing mass that pushes galaxies too far away according to former estimates of their masses and their distances. Besides the equalized mass, the need for which has emerged from presence of nonradial potentials acting along paths on equipotential surfaces in radial/center-bound force fields, the repulsive effects of the nonradial angular potentials can also amplify the regular/innate spins of stars, black holes and galaxies, eliminating thus the need for the so-called dark matter/energy invented just to explain the allegedly missing mass/energy.

Opis:
The Borowski Theory of Gravitation (BTG) indicates that movements of mass such as planets through space are determined by differential pressures from dark matter. One of the consequences of the final epoch is that there would be no matter but only distance. Quantitative solutions indicate that the tensor to set universal average dark matter pressure equal to G, the gravitational constant, would require that the terminal length would be ~2.2∙1069 m or effectively identical to current estimates of energy equivalence of the universal mass. For the earth’s orbit the force from the dark pressure is the same order of magnitude as the force associated with the product of the planet’s mass and background free oscillations whose origins are still ambiguous. The convergences of solutions suggest that the BTG may reveal alternative interpretations and mechanisms for the role of gravitation in planetary motion.

Opis:
The aim of this paper is to examine the ‘dark matter’ assets in the external sector of the United States in the period 1999:Q1-2018:Q3. The paper investigates data on the balance of payments and international investment position for the US and a group of 18 economies. The research reveals that the US is a privileged economy with respect to foreign income on international investments. The rates of return on its foreign assets are relatively higher, and the costs incurred on its foreign liabilities relatively lower, as compared with the benchmark group. This special privilege of the US relates to equity investments, especially foreign direct investments. Based on prevailing income differentials substantial ‘dark matter’ assets of the US are estimated. Recognising such ‘dark matter’ leads to the conclusion that the US is a foreign creditor, not debtor. The findings shed light on the puzzle as to why the US has a continuing ability to sustain its external position despite mounting foreign liabilities. Keywords : international finance, balance of payments, income account, international investment position, ‘dark matter’ hypothesis.

I think that far-away travels into Space are possible in the way that it is possible to find again people on our Earth, after the return of a very long travel into Space, not aged, like the people who have traveled inside the spacecraft. Current physics does not allow this and I have developed the following Theory which would thus complement the current Theory of General Relativity when we go to the limits of the reasoning. Current Theories like General Relativity or Quantum Mechanics are not impacted when the reasoning is not pushed to the limits. My reasoning at the limits just complements current Theories when the parameters take extreme values and thus the logic of current physics is respected.

Opis:
W listopadzie 2022 r. CERN podpisał umowę ze Szpitalem Uniwersyteckim w Lozannie (CHUV) i firmą technologii medycznej THERYQ na opracowanie nowatorskiego urządzenia do radioterapii „FLASH”. Urządzenie – pierwsze tego rodzaju i oparte na technologii CERN – będzie wykorzystywać elektrony o bardzo wysokiej energii (VHEE) do leczenia nowotworów opornych na konwencjonalne metody, przy zmniejszonych skutkach ubocznych. Obecnie ok. jedna trzecia nowotworów jest oporna na konwencjonalną radioterapię. Fizycy potrafią uzyskać w akceleratorach cząstek lekkie antyatomy, jak antyhel czy antydeuter. Dotychczas jednak nie zaobserwowano ich w przestrzeni kosmicznej. Tymczasem z modeli teoretycznych wynika, że antyatomy, podobnie zresztą jak antyprotony, mogą powstawać zarówno w wyniku zderzeń promieniowania kosmicznego z materią międzygwiezdną, jak i podczas wzajemnej anihilacji cząstek antymaterii. Sygnałów takich poszukuje m.in. zbudowany przez CERN spektrometr AMS (Alpha Magnetic Spectrometer) zainstalowany na Międzynarodowej Stacji Kosmicznej. Airbus UpNext, spółka zależna należąca w całości do Airbusa, oraz CERN, Europejskie Laboratorium Fizyki Cząstek, rozpoczęły projekt mający na celu ocenę, w jaki sposób nadprzewodnictwo może przyczynić się do dekarbonizacji przyszłych systemów lotniczych. Demonstrator Super-Conductor for Aviation with Low Emissions (SCALE) ma na celu promowanie adaptacji i wdrażania technologii nadprzewodników w lotniczych systemach dystrybucji energii elektrycznej. Bozon W, podstawowa cząstka przenosząca naładowane oddziaływanie słabe, był przedmiotem nowych precyzyjnych pomiarów jego masy w eksperymencie ATLAS w CERN. Wstępny wynik, przedstawiony w nowej notatce konferencyjnej zaprezentowanej na konferencji Rencontres de Moriond, opiera się na ponownej analizie próbki 14 mln kandydatów na bozony W, wyprodukowanych w zderzeniach proton-proton w Wielkim Zderzaczu Hadronów (LHC), sztandarowym akceleratorze cząstek w CERN.
In November, CERN signed a contract with the University Hospital of Lausanne (CHUV) and medical technology company THERYQ to develop a novel "FLASH" radiotherapy device. The device – the first of its kind and based on CERN technology – will use very high energy electrons (VHEE) to treat cancers that are resistant to conventional treatments, with reduced side effects. Currently, about a third of cancers are resistant to conventional radiotherapy. Physicists can obtain light anti-atoms, such as antihelium and antideuterium, in particle accelerators. So far, however, they have not been observed in space. Meanwhile, theoretical models show that antiatoms, similarly to antiprotons, can be formed both as a result of collisions of comic radiation with interstellar matter, and during mutual annihilation of antimatter particles. Looking for such signals, e.g. the CERN-built AMS (Alpha Magnetic Spectrometer) instrument installed on the International Space Station. Airbus UpNext, a wholly owned subsidiary of Airbus, and CERN, the European Laboratory for Particle Physics, have launched a project to assess how superconductivity can contribute to the decarbonisation of future aviation systems. The Super-Conductor for Aviation with Low Emissions (SCALE) demonstrator aims to promote the adoption and implementation of superconductor technology in aviation electrical power distribution systems. The W boson, a fundamental particle that carries the charged weak force, was the subject of a new precision measurement of its mass by the ATLAS experiment at CERN. The preliminary result, reported in a new conference note presented at the Rencontres de Moriond conference, is based on a reanalysis of a sample of 14 million W boson candidates produced in proton–proton collisions at the Large Hadron Collider (LHC), CERN’s flagship particle accelerator.

Opis:
The message is that physics has an „outward bound” of scientific inquiry in the field of cosmology. I present it in the historical development. Physics and astronomy, developing since the seventeenth century, inherited from the early Greek philosophers the conception that the Universe as a whole is invariable. In nineteenth century this conception in conjunction with the conception of eternity of the Universe (being a philosophical conclusion from the conservation laws of mass and energy) gave rise to contradictions with other laws of physics indicating that cosmology is not a branch of physics since the notion of the Universe is not a physical one. Cosmology returned to physics as its important branch due to the advent of general relativity theory and the discovery of the cosmic microwave background radiation. Modern cosmology generates fundamental problems creating real limits to inquiries in physics viewed as an empirical science. The very notion of the Universe shows that the scientific method reaches there limits of its applicability. Does „to exist” mean „to be observed by someone”? Should the definition of the Universe be based on a current physical theory, e.g. on Einstein’s general relativity, giving rise to a kind of mathematical instability? Is the fashionable concept of the „multiverse” a physical one or is a purely metaphysical notion in a scientific disguise? If the Universe is unique (as we believe), is it meaningful to describe it in the framework of physics, which by its method always assumes that the number of objects it describes, is unlimited? Apart from these permanent philosophical problems there are concrete urgent problems generated by cosmology: the nature of dark matter and dark energy. These two species of „substance” appear only in cosmology and do not fit the laboratory physics; contrary to the three centuries long tradition of modern science, now cosmology inspires physics in a troublesome way. A separate class of limits to physics is generated by the theorem in general relativity that the Universe emerged from an initial curvature singularity of the spacetime. At the singularity the whole scientific inquiry breaks down. Cosmology of the very early Universe suggests that in its evolution two specific epochs took place, that of quantum gravity and an inflationary epoch. The underlying them two physical theories are incomplete and seem to be inherently untestable. Furthermore, the experimentally verifiable physics cannot explain the origin of the initial conditions determining properties of the Universe which emerged from the singularity.
