Stellar Distortions Could Smear SETI Signals, Reframing the Search for Weaker Signatures
To the point
Signals from intelligent civilizations may be distorted and weakened as they travel through a star’s plasma and magnetic fields, especially around red dwarfs that dominate about 75% of Milky Way stars and can scatter energy so much that much of the signal never reaches Earth, so searches should target weaker, smeared signals rather than only sharp, narrow spikes.
