The Earth's magnetic field is rapidly weakening, making our planet less shielded from solar sunspot cycle and coronal mass ejections
Solar sunspot cycle is strongly correlated with wars and civil unrest throughout history (and diseases, unemployment, etc)
We are at the max 🧵

The current sunspot cycle is near its maximum, right now, as we enter 2026.
Meanwhile the decline of Earth's magnetic field strength is accelerating.
This is especially true in South America right now.

"That doesn't make sense! How could the Sun influence human behavior?"
The Earth has an ionosphere which acts as a giant resonant cavity for low-frequency electromagnetic waves.
This Schumann resonance is at the same frequency as Human alpha and theta brain waves

Alpha and Theta brainwaves are associated with deep relaxation, calm focus, meditative states.
It's possible that disruptions to the Schumann resonance in this frequency range disrupts these states, making us agitated, quick to anger, upset, etc.

There is a huge amount of published literature finding associations between the solar sunspot cycle and any number of social, biological, and psychological phenomenon.
Disease, unemployment, wars, famines, the list goes on.

Is there anything we can do about it?
Yes, and it involves the heavy launch capacity, superconductors, and large-scale space structure deployment.

The dipole moment of an electromagnet is a product of the area of its loop and current. For Earth, the equivalent dipole is around 8e22 Ampere-meters.
We could supplement this with a much smaller dipole, something like 10e18 A-m.
Stationed at L1.

A superconducting magnetic with a 2 Tesla field strength and loop diameter of 1-10km should do the trick.
This would require gigatons of superconducting tape and about a gigawatt of on-board power supply.
Fortunately, we only now have the ability to do this:

The commercial Fusion industry has rapidly brought economies of scale to mass manufacture of high-temperature superconducting tape to produce 6-12 Tesla magnets for magnetic confinement.
And, Starship will soon exponentiate our heavy-lift space capabilities.

This would be a Promethean task at civilizational scale and the first true act of planetary-scale space engineering.
Supplementing the Earth's natural magnetic field, preventing the further cycle of civil unrest, wars, disease, and so on.
