I think those Schumann frequencies are important for Life itself.
Otherwise there would be no reason at all for them to exist.
Now, it does not really matter to me if they work "actively" or "passively".
There MUST be at least A reason for them to exist. We can discuss over which one(s) is.
We live in a world of vibrations, we ARE vibrating as we read this topic and animals - like for example, the extraordinary ants - use them to feed themselves and get their life organized etcetc
We are messing around with frequencies and I am not surprised people today are more confused re what to do than ever before.
Since I am barefoot all day, stepping on natural surfaces/elements (water, mud, grass, stones..) I can feel a light tickling under the soles of my feet.
Guess it is because my blood flow is more stimulated than when I wore shoes..
And this single thing surely impacts the Whole, cannot tell scientifically how.
I can only write "hippy proses" to try to express the way I feel

IMO we gotta keep in mind science is finite and it is relative to the "time" and the "main stream beliefs" of its era.
Since we are running more and more towards a full transhumanist era, I can already predict (well, that is an easy guess, given the present trends

..) there will be a time when it will be "scientifically "proven that we do not need real food anymore, it is enough to swallow a tiny pill..
