  1. How do you feel about the improvement of space equipment? Some things make me think that they came to us from another time. Some from the future, some from the past. Here https://www.skyrora.com/blog/uk-space-news I read an article about installing new equipment, which should speed up the data transfer process. How likely is it that we will ever get instant data transmission over long distances? Is instant data transmission only possible for quantum communication? Or are there other ways?
  2. I think there is a good reason why this effect is not used. How do you imagine a rotating ship? How fast does it have to rotate to reach an acceptable speed? Even disregarding what happens to the insides of such a device (equipment, astronauts ...), how much energy does it take to spin the ship?
  3. https://theconversation.com/wormholes-may-be-lurking-in-the-universe-and-new-studies-are-proposing-ways-of-finding-them-153020 Astronomers think wormholes exist at the centres of very bright galaxies. There are no articles yet describing the detected wormholes. But they have already suggested ways to search. If the theory turns out to be true, what could be the difference in exploring the universe? (If the nearest wormhole is 13 million light-years away, then ... it is unlikely that anything will change)
  4. Will we ever learn how to use a wormhole? Scientists have already agreed that wormholes exist? Could it be portals not only in space, but also in time? In theory, a spaceship can pass through such portals. However, they are surrounded by intense radiation, which negates the crew's chances of survival. In addition, the closest similar object is 13 million light-years away, so humans are unlikely to be able to reach it in the foreseeable future.
  5. You can connect for $ 600. Then I paid 99 dollars a month. Satellites are launched into orbit every week. With an increase in the number of satellites and users, a gradual decrease in cost is quite possible. The good thing is, these satellites have a plan to get out of orbit. (Apparently, this has something to do with the recent new rule for using working orbits). This means that they will not increase the amount of space debris.
  6. My prediction. In 20 years, there will be a network of filling stations for satellites and rockets in orbit. The whole world will be covered by a global satellite Internet with a stable connection. It will be prohibited to launch into space equipment that cannot be reused, refueled or safely returned to the atmosphere. All purchases will be made without leaving your home. Delivery will be carried out using drones. Not a single global problem will be resolved.
  7. My guess is that water is easier for scientists to detect. In addition, the capabilities of our technology do not allow us to check the existence of life at a great distance. Perhaps, in a few decades, the progress of technology will allow us to search for life itself, and not the conditions necessary for its formation. In the meantime, research is based on the human knowledge base. As I understand it, we are looking for organic life because we do not know about another.
  8. In order for life to exist on the planet, liquid water must be present on its surface. Calculating the likelihood of this scenario seemed almost impossible before. It was previously assumed that terrestrial planets receive water randomly, as a result of a large ice asteroid hitting the planet's surface. In a new study, scientists from the GLOBE Institute at Copenhagen University, Denmark, have published breakthrough results showing that water may have been present in the planetary matter even during their formation phase. According to the team's calculations, this scenario could have occurred in the case of Earth, Venus and Mars. In the future, Johannessen and his team plan to test their hypothesis with observations that will be carried out using a new generation of space telescopes, which will provide more opportunities for observing exoplanets orbiting stars other than the Sun.
  9. In the Martian meteorite Allan Hills 84001, found in 1984 in Antarctica, Japanese planetary scientists were able to construct ancient nitrogen-rich organic molecules. This means that organics existed on early Mars, carried by meteorites or formed directly on the planet. Since then, there has been no sensational news. The name Perseverance makes a lot of sense. We are persistently looking for something that may not exist.
