Astrophysicists claim that our universe is not the best suited for life, hardly harmonic However, it is a wonder that it could form on our Earth due to accidental collusion and a combination of parameters. Maybe that's why we haven't encountered alien life forms yet, or because of what Stephen Hawking said:
According to a joke, but actually a disturbing one, the reason we can't contact aliens is because when a civilization reaches our current level of development, it becomes unstable and destroys itself.
In the journal Proceedings of the National Academy of Sciences (PNAS) for less than half a year published In the research, a group of scientists announced a new technique that can take a sample of a substance, feed it into a machine learning algorithm, and find out with up to 90 percent accuracy whether the substance comes from a living organism. Of course, this would be a big help if we were looking for life on Mars, for example, or elsewhere in outer space.
The germs of this technology were already present 46 years ago on Viking rovers that landed on Mars. They used mass spectrometry and used heat to break down the chemical components of the substance to determine what chemicals were present in it. But in 1978, more detailed resolution of the data was still limited and not yet available Amnesty International With algorithms.
New technology may finally provide an answer as to whether there was life on Mars, Europa or one of Saturn's moons, Enceladus, whose surface is covered by a thick shield of ice. According to hypotheses, there may be a deep ocean beneath this, which hides the rocky core of the Moon.
If life arose here or elsewhere under different conditions, it would still operate according to rules similar to those on Earth.
Water freezes solidly on Saturn's largest moon, Titan, which is the only body in the solar system that contains hydrocarbon rivers and lakes of ethane and methane. Using AI technology, it would be easy to analyze whether there is life here: a sample of Titan would be burned, the spectrometer would analyze it, and the algorithm would classify it into two categories. Either a substance that we know exists in nature, or something that could be considered an anomaly in our world. Biological markers can also be found in the latter.
outside our solar system
The James Webb Space Telescope recently discovered traces of a compound called dimethyl sulfide on the exoplanet K2-18b, located 124 light-years from Earth. This planet is not very similar to anything in our solar system, but its surface may be oceanic, as methane and carbon dioxide indicate. On Earth, dimethyl sulfide is produced primarily by phytoplankton.
Life may or may not be common in the universe. We currently have no evidence of extraterrestrial life, so we can only speculate. In addition, life is not enough, you also need intelligence to communicate, but this can be more rare than life. But advanced intelligence is more than that.
The Kardasev scale, developed by Nikolai Kardasev in 1964, shows the different levels of development of species, and ranks civilizations according to how efficiently they harness the energies of the universe. One Some types Civilization uses the entire solar energy of the planet. One, two You can use the full energy of the star in the given system, but a Triple! He is actually capable of using energy on a galactic level. We're not even at one level, but in a 2022 study, researchers concluded that it could be achieved by 2371 at the current rate of development. But if we were influenced by alien technology that was more advanced than our own, that could speed up the process. Of course, there is something else that could hold him back. However, artificial intelligence can be of great help in achieving this.
