  1. For this purpose, submarines with cruise and ballistic missiles are more suitable. They have an advantage over aircraft carriers and battleships, which is the ability to covertly go to a given area on the line of attack. From the point of view of the strictness of the terminology, we should say "semi-ballistic". The head of such a missile must be able to maneuver and be homing on radiation from the aircraft carrier's electronic equipment. According to this scheme, it is possible to make a long-range surface-to-air missile against flying AWACS radars.
  2. To answer the question about the return of battleships, it is necessary to answer the question, and what combat tasks are these ships supposed to solve? If this is a fight against enemy carrier strike groups, then there are more promising solutions for this. For example, there have been reports on the Internet that China is developing ballistic anti-ship missiles with a range of 2,000 km
  3. Hardly. The development of military technologies is moving in the direction of removing living soldiers from the battlefield. Unmanned aerial vehicles, tanks without crews......
  4. The observer is another particle with which the photon interacts.
  5. here I googled it https://arxiv.org/abs/2009.11525
  6. The researchers, led by Frederico Lelli and Harry Desmond, studied 153 galaxies and measured the speed of the stars inside them at different distances from the original galactic center. They then looked at the acceleration of each galaxy caused by the gravitational fields generated by its surrounding neighbors. Some of the star systems, as it turned out, move 10 times faster than the rest. They then selected the two galaxies with the largest gravitational tug and compared their rotation patterns with the two isolated galaxies. Scientists have found that stars in strong gravitational fields rotate more slowly than the model of behavior of isolated galaxies predicts. They also studied galaxies with intermediate external gravitational fields and found that the data obtained were consistent with the characteristics of each galaxy. The correlation with the external environment is obvious. Thus, it violates the equivalence principle derived from GR. The quote is taken from here https://alter-science.info/p/341.html and translated into English.
  7. The particle simply does not have a specific coordinate and a specific momentum at a given time. This is what the Heisenberg uncertainty relation says. Until a particle is detected, it passes through all the slits of the diffraction grating at once.
  8. And if the astronaut falls forward head first, then when the neck is at the level of the event horizon, it becomes impossible to transmit nerve impulses from the head to the heart and lungs, it turns out that the event horizon will work like a guillotine or a cholinesterase inhibitor, so what????
  9. But string theory also states that the dimension of the space of the universe is 10+1. A coincidence????
  10. In physics, the proton-to-electron mass ratio, μ or β, is simply the rest mass of the proton (a baryon found in atoms) divided by that of the electron (a lepton found in atoms). Because this is a ratio of like-dimensioned physical quantities, it is a dimensionless quantity, a function of the dimensionless physical constants, and has numerical value independent of the system of units, namely: μ = mp/me = 1836.15267343(11).[1] The number enclosed in parentheses is the measurement uncertainty on the last two digits. The value of μ is known to about 0.1 parts per billion. It was also noticed that μ ≈ {\displaystyle 6\pi ^{5}.}[2] https://en.wikipedia.org/wiki/Proton-to-electron_mass_ratio And the number pi in the fifth power is included in the formula of the volume of a ten-dimensional ball.
  11. And I have another question about the proton. The proton mass refers to the electron mass as 6*Pi^5. Why is Pi in the fifth power? Is this an indication that our space has 10 or 11 dimensions? The volume of a ten-dimensional ball (Pi^5)*(R^10)/120
  12. The Heisenberg uncertainty relation also violates the law of conservation of energy for time delta t.
  13. What will be the detonator of this explosion? Even photons can't escape beyond the event horizon of a black hole, so how does all the matter in the universe end up outside the event horizon of this black hole? In general, the atheist's dream is to create a model of a cyclic Universe that would exist forever and, therefore, would not require a Creator. But this criterion is better met by a model in which our Universe is part of a multiverse, in which Big Explosions constantly occur, giving birth to new Universes.
  14. The law of jet motion was brought out by an unknown math teacher from the city of Kaluga (Russia).
  15. I believe that in the multiverse, there are innumerable Big Bangs constantly occurring, giving birth to universes. This is similar to the birth of virtual particle-antiparticle pairs.
  16. The energy of the individual bodies that make up the system can be different. But the total energy of all systems of bodies, depending on the chosen frame of reference, should not change.
  17. Feynman said that quantum mechanics is impossible to understand.
  18. God was invented by people, and in their own image, in order to explain what is currently not explained. At present, God is not needed to explain the origin of the universe.
  19. A distinction should be made between the" weak equivalence principle "and the"strong equivalence principle". A strong equivalence principle can be formulated as follows: at each point in space-time in an arbitrary gravitational field, one can choose a "locally inertial coordinate system", such that in a sufficiently small neighborhood of the point under consideration, the laws of nature will have the same form as in non-accelerated Cartesian coordinate systems of SRT, where "laws of nature" mean all the laws of nature. Quote from https://ru.wikipedia.org/wiki/Принцип_эквивалентности_сил_гравитации_и_инерции, The key word here is ALL the laws of nature. What about the law of conservation of angular momentum? Energy of the rotating gyroscope E = J*(w^2)/2 = Lw/2. If the gyroscope approaches a massive body, its angular rotation frequency w will change due to time dilation. And then, in order for the energy of rotation to be preserved, it is required that the angular momentum L changes.
  20. The universe is finite. This follows from the law of conservation of energy (once the stars must burn all the hydrogen), as well as from the second law of thermodynamics. And then, either our universe is part of something larger (the multiverse), or we must accept the existence of God. Which point of view is closer to you personally?
  21. In the current situation in the global economics, environmental energy can become the lifesaver that will help to bring it out of a depressed state. Because it can create a lot of jobs.
  22. Along with the search for and explanation of dark energy and dark matter, astronomers are faced with a third task: to find the missing "normal" (or as it is also called baryonic) matter of the Universe, writes IFLS. https://www.iflscience.com/space/a-little-of-the-universes-missing-matter-has-just-been-found-close-to-home/ The scientists ' innovative approach found that a tiny fraction of the missing matter lurks close enough (by astronomical standards) to the Solar System, suggesting that such zones are quite common. Unlike dark matter and dark energy, the missing matter must be a normal gas and possibly a small amount of dust, like the universe we can see. "The problem is that when we look back at the early universe, we can measure the amount of matter that was then present in it, but in more recent observations, half of it has disappeared," the study authors write. Even if we allow the transformation of matter into the energy of stars, the most visible matter will not be so much. Over the past few years, astronomers have made considerable progress in finding this missing matter, for example, they found most of it in diffuse gas between galaxies hundreds of millions of light-years away. However, this is still not enough. Yuanming Wang, a PhD candidate at the University of Sydney's School of Physics, has developed a rather unusual method to help find the missing matter. She used her technique to determine a hitherto undetected stream of cold gas in the Milky Way about 10 light-years from Earth. "This gas is impossible to detect using traditional methods, as it does not emit its own visible light and is simply too cold to detect using radio astronomy," Wang said. She found it when she was looking at the twinkling galaxies. Astronomers have long known that some galaxies flicker when observed with radio telescopes.
  23. And then you need to look at what is more profitable, to lay a power line from the Sahara to Europe or to build wind farms on the European coast. Here is the latest news on this topic https://www.bbc.com/news/world-europe-55931873 In addition, the power line from the Sahara to Europe must cross the sea. Communication cables and oil and gas pipelines are laid under water, but I haven't heard about underwater high-voltage power lines. This is what the insulation of an underwater high-voltage cable should be. In addition, the construction of wind farms on the European coast creates jobs in Europe.
  24. This means that there is a problem of a sufficient number of electricity consumers in this region.
  25. And the main problem of the Sahara is water.
