In 1610, Italian astronomer Galileo observed sunspots through a telescope.
In the 1850s, Wolf, director of the Zurich Observatory in Switzerland, designated the period from 1755 to 1766 as the first solar cycle.
Based on this, around 2025, Earth is in the rising phase of the 25th solar cycle. Given the average sunspot cycle of 11.2 years, solar activity is expected to reach its peak in the months after May 2025.
When sunspot activity is intense, it has an enormous impact on Earth's magnetic field. Unlike the centuries before it, the 21st century is an age of rapidly advancing technology in human civilization.
Satellite and wireless communication technologies have become widespread in people's lives and occupy an extremely important place in them.
At the same time, this cycle is different from previous ones.
The ferocity and duration of this sunspot outbreak far exceed those of any previous event.
Earth's civilization was unprepared for what happened. Because wireless communication is so important to everyday life, this period of sunspot activity transformed from a natural spectacle into a natural disaster that many people could not accept.
Faced with an unforeseen cosmic event, human technology seems so small and powerless. And when the comfortable habits of daily life that people have developed are suddenly taken away, how can ordinary people cope and protect themselves amid this natural maelstrom? Can they free themselves or find salvation?
