A Russian scientist warned of the impossibility of predicting destructive solar flares despite the ability to predict daily activity, pointing out that such events may be many times stronger than what we have observed, and that the last of them occurred in the year 700 AD before the existence of modern technology.

Solar flares are divided into five categories based on their X-ray intensity: A, B, C, M, and X, where A is the weakest and the strength increases tenfold with each higher category. These flares cause magnetic storms measured from G1 to G5.
The scientist explained, saying: “Modern science is good at predicting daily solar activity and solar weather, but unfortunately, it is almost impossible to predict exceptionally strong events, usually after they occur.”
According to Bogachev, very strong solar flares can pose a threat to power grids and electronic equipment, and satellite systems are the most vulnerable. It is difficult to accurately evaluate such flares, as modern humanity has not yet witnessed truly “devastating” solar events.
He added: "We conclude from solar archeology that the sun produces solar flares that are hundreds, or even thousands, of times stronger than the largest flares that we have observed during the past hundred years. I believe that the last such event was around the year 700 AD, when technology did not yet exist on Earth. We have no idea how technology interacts with it."
However, the scientist believes that modern electrical networks are sufficiently protected from weaker and more frequent solar flares, and believes that these flares may only cause automatic disconnection of electrical circuits, as happens in cases of normal overloads.
Solar flares are divided into five categories according to the intensity of the X-rays they emit: A, B, C, M, and
These flares lead to magnetic storms that may cause disruption in energy systems, affect the migration paths of birds and animals, and may also affect the work of communications and navigation systems on Earth. The intensity of storms is divided into 5 degrees according to the disturbances that occur in the Earth’s magnetic field, and the intensity of the storm is coded from G1 (weak) to G5 (very strong).

The article explores how general anesthetics, despite their widespread use in more than 350 million surgical procedures annually, their mechanisms of action are still not fully understood, and how their effect on the brain provides a window into understanding the nature of consciousness, including the hypothesis of a third state of consciousness and the effect of anesthesia on the functional connectivity between brain regions.
