In the interior of stars, y-quanta are processed into quanta of visible radiation – photons. Is the reverse process possible in space – an increase in the frequency of a quantum of electromagnetic radiation?
The inverse process is Compton scattering of quanta by relativistic electrons. As a result, radio emission can turn into electromagnetic waves in the optical range.
Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
