Stefan Burns (geophysicist) and Ben Davidson (Suspicious Observers) both provide evidence that this is the case, but seem to come to very different conclusions. Both of them link the root cause not to the Sun, but to the movement of the solar system through the galaxy, and specifically the periodic movement into and out of the dusty plasmas and the galactic current sheet.
If you were to rely on Google, you might be fooled into believing the galactic current sheet was just a theory, not yet observed. Donāt rely on Google.
Oddly enough this AI/app provides a really good summary of one of Benās videos on the topic: Galactic Magnetic Shock: Unveiling a Phenomenon ā Eightify
But I think one of the better summaries was this one: https://www.youtube.com/watch?v=N3s01hCDyyw
I could swear Stefan had a video on the topic as well that had a much more positive spin to it and went more into the effect on consciousness, if I find it Iāll link it to you. But there are definitely major changes to the sun and the rest of the solar system as a result of the galactic current sheet impact, including changes in seismicity on Mars and atmospheric changes in the outer planets.
