The free-falling charged particle radiates the electromagnetic wave. The charged particle on the surface of the earth does not radiate the electromagnetic wave. The existence or the non-existence of the electromagnetic radiation from the charged particle and the back reaction of that is independent of the observer, which is consistent with the energy conservation. A paradox comes from combining this phenomenon with the equivalence principle in the theory of the general relativity. We consider the Hawking effect in the context of this paradox. We give our resolution on this paradox.","PeriodicalId":292629,"journal":{"name":"European Journal of Applied Physics","volume":" 32","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140995644","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our organization is currently developing quantum propulsion systems and space vehicles that will be capable of flying with enormous speed (potentially reaching and exceeding the speed of light) and will have unseen-before manoeuvrability and lifting capacity. They will provide 100% crew protection from deadly sun and space radiation which is essential for safe deep space travel and manned space exploration. They will also provide spacecraft with protection against space particles. To date, we have managed to crack the main secret of practical quantum engine design and we are ready to develop it further into fully operational aerospace vehicles. Quantum propulsion systems are the only systems that can facilitate realistic prospects of space mining on the industrial scale and deep space colonisation, including colonisation of habitable planets in the future. The cost efficiency of this new technology is going to be enormous. Development and production costs of quantum aerospace vehicles compared to production costs of chemical fuel jet spacecraft allow to reduce price per kilo space launch ratio hundreds of times, making deep space exploration and commercialisation more accessible and practically feasible at last. Manufacturing and maintenance of quantum-propelled flying machines that can reach the age of our solar system within hours will be no more expensive than manufacturing jet planes or helicopters of the same size. Quantum propulsion systems are going to replace outdated chemical fuel rocket and jet engines in the near future and will become the mainstay of air travel and space exploration.","PeriodicalId":292629,"journal":{"name":"European Journal of Applied Physics","volume":"8 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140258967","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this model, the photon spin-orbital speed is slowly decreasing in the free space of the Universe. The formulae for the wavelength, frequency, local time, momentum, energy, temperature, and photon energy dilation are presented for cosmological photons outside of a gravitational field. The Hubble constant H⊕ = 2.3195 ∗ 10−18 s−1 (= 71.572 kms−1Mpc−1) is calculated as (G M⊕)/(R⊕ c3) ∗ dcrotational/dt where G is the Newtonian gravitation constant, M⊕ is the Earth’s mass, R⊕ is the Earth’s radius, and crotational is the rotational speed of Descartes’ light “globules” without any fitting. The cosmological photons expand their wavelength in the Earth’s gravitational field based on the age of those photons determined via their redshift given as (1 + z). This newly defined Hubble constant can be falsified in the gravitational field of the Moon, and Mars. The simple formulae for the angular diameter distance dA, the luminosity distance dL, the distance modulus m—M, the concentration of galaxies at the redshift z can be tested on the recent data. E.g., the distance modulus was several times tested on the cosmological objects till their redshift z = 5 (references to those studies are given). The formula for the angular diameter distance dA was recently tested for the data taken using the James Webb Space Telescope (JWST) by Lovyagin et al. and the value of dA followed the data trend better than the standard model. This Descartes’ hypothesis can start a discussion of Descartes’ cosmological photons can newly explain experimental data without fitting in Euclidean space.","PeriodicalId":292629,"journal":{"name":"European Journal of Applied Physics","volume":"33 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140458302","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Descartes’s code is the old color theory (published in 1637) based on the rotation of “light globules”, however, it was rejected by Newton in 1672. In this model, the photon spin-orbital speed is modified by the gravitational field. The formulae for the wavelength, frequency, local time, momentum, energy, and temperature of photons in the gravitational field are identical in the first order both for the Schwarzschild solution and Descartes’ code. To experimentally determine the predictions of Descartes’ photon model we have to search for the experiments in the second order or for the situations where the standard model has to postulate some hidden elements (e.g., the dark matter). Some examples are presented here. The new interpretations of the bending of light by the Sun and the Shapiro time delay are given. The Anderson acceleration constant known as the Pioneer anomaly was derived as the effect of the Earth’s gravitational field on photons. Similar acceleration could be found in invaluable data from the Laser Lunar Ranging experiment. Stellar photons are modified by the Solar gravitational field at the distance of 1 AU and the acceleration constant identical to the Milgrom acceleration (MOND gravitational model) was derived. Therefore, we should study in more detail the influence of the Solar, Earth’s, and Moon’s gravitational fields on photons to avoid traps with false gravitational models.","PeriodicalId":292629,"journal":{"name":"European Journal of Applied Physics","volume":"9 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140494154","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This confirms that the force of gravity between the planet and the sun is in the form of a spring, which explains the following: for example, when the Earth is at the closest possible point to the sun, the Earth moves away from the sun, even though the force of gravity is as great as possible. This behavior of maximum compression of the spring is called the maximum compression gravitational force. It also explains that when Earth is at the furthest possible point from the sun, it approaches the sun again, even though the force of gravity is as small as possible.
