  1. Unfortunately, it is pointless to set up such an experiment. Due to the very small value of the Hubble constant, 2.2*10^-18 1/s, its results will have to wait several million years.
  2. Here it is necessary to add a reservation "for an external observer".
  3. Are you sure that this frequency standard is absolute? Are you sure that if you move this caesium atom (like an atom of any other chemical element) to a point with a different gravitational potential, its spectrum will not shift?
  4. The thing is that we do not and cannot have absolute standards of distance and time. The distance between galaxies increases faster than the size of the galaxies themselves and we only see this difference. Therefore, we will not be able to notice the red shift of photons in the box because there is no absolute standard of frequency to compare with.
  5. Will be. As the universe expands, the dimensions of the mirror box will also increase. I.e., the walls of the mirror box are constantly moving in different directions, photons should experience the Doppler effect with each reflection from the walls of the box.
  6. Scientists have discovered that a distant neutron star has released as much energy as our Sun produces in 100 thousand years in just 0.16 seconds, writes Scientific American.
  7. Artificial intelligence in one of the district people's prosecutor's offices in Shanghai for the first time became the compiler of the text of the indictment, which will be presented to the criminal in court. This is reported by Economic News with reference to haggin.az According to the South China Morning Post newspaper, AI received prosecutorial skills after studying more than 17 thousand cases considered in the courts of Shanghai from 2015 to 2020. The "digital prosecutor" makes accusations with 97% accuracy, based on one thousand "characteristic features" that he identifies in court documents on specific criminal cases. "Artificial intelligence to a certain extent can replace prosecutors in the decision-making process, as well as assist them in drafting indictments, which will reduce their daily workload and enable prosecutors to focus on more important cases," the publication notes. According to the newspaper, the "digital prosecutor" is initially able to bring charges for eight of the most common crimes in Shanghai, such as credit card fraud, gambling, dangerous driving, intentional injury, obstructing authorities in the performance of official duties, theft, fraud. Scientists are confident that in the future AI will be able to bring charges for more high-profile crimes.
  8. Scientists at the Massachusetts Institute of Technology, Cardiff and Cambridge Universities have figured out what chemical reactions could make the clouds of Venus habitable. The fact is that ammonia found in the atmosphere of the planet in the 1970s is able to neutralize drops of sulfuric acid, writes MIT News. https://news.mit.edu/2021/habitable-venus-clouds-acid-neutralizing-1220 And then there could be biological species similar to terrestrial ones. The scientists explained that ammonia turns acid into ammonium sulfite, which in itself can create an environment in the clouds of Venus suitable for life. Scientists were prompted to conduct a study by mysterious anomalies in the clouds of Venus – such as small concentrations of oxygen, which should not be there.
  9. CNN: US authorities are preparing to evacuate citizens from Ukraine in the event of a Russian invasion https://www.cnn.com/2021/12/07/politics/us-citizens-evacuation-ukraine/index.html
  10. The majority of the population of Taiwan does not want Taiwan to join China, but the majority of the inhabitants of Crimea wanted to join Russia. The movement of Russian troops near the borders of Ukraine is pressure on Ukraine not to launch an offensive on Donetsk and Lugansk.
  11. The military budget consists of expenses for the maintenance of military personnel, expenses for the purchase of weapons and other purchases not related to weapons. If the cost of maintaining personnel increases, it is at the expense of other expenses.
  12. Russia has approved the defense budget for 2021-2023 — it was reduced by 10%. Despite this, it guarantees the combat readiness and development of the country's Armed Forces. Deputy Minister of Defense of the Russian Federation Tatyana Shevtsova told the newspaper Krasnaya Zvezda about this. https://360tv.ru/news/army/rossija-sokratila-bjudzhet/ At the same time, military salaries have been increased in Russia, so the cost of purchasing weapons will be reduced even more.
  13. And if Aliyev and Erdogan also seize Armenia Earlier, Aliyev had already stated that Yerevan belongs to Azerbaijan
  14. It seems to me that a more important physical constant is 4 *Pi*G*epsilon0, which shows how many times stronger bodies with masses of 1 kg interact gravitationally stronger than two charges of 1 Coulomb at the same distance. The dimension of this constant is Сoulomb^2/kg^2 that is, it does not depend on the distance scale.
  15. In 2014, Putin could have seized the whole of Ukraine, but limited himself to Crimea. Putin only needs the opportunity to export gas to Europe. He can send troops into Ukraine only in response to Ukraine's actions, which may be the offensive of Ukrainian troops on Donetsk or the blockade of Tiraspol.
