Schumann is correlated with the Sun bigtime. Doesn't take even 2 braincells to notice that the readings are much stronger in Spring / Summer. I think there are other factors / variables involved but the Sun is the most important one.
Do I have to be direct exposure to receive the signal or am I wasting a powerful upgrade being inside?
Sunlight carries photons and waves so it is appearing on your drapes. You've created a double-slit experiment of sorts. It would actually take a lot of energy for me to explain it to you right now. I was just lucky to have a Master's in Physics as my Grade 12 Physics teacher. Gave that entire class a succinct, abridged, Master's Degree in physics within 4 months. If you were paying attention anyways.
I dunno though try vid related.
Still awesome pic though, too lazy to convey in words right now the Physics but you wrinkled my brain a bit.
This is like the Pre-patch before the next expansion pack.
You made it on 8kun so that's a good thing to have in your portfolio. I would plead your case with that.
