For data transmission I always thought it was less about an electromagnetic signal's ability to penetrate and more about its ability maintain cohesion during diffraction while having an appropriate amount of bandwidth for the application. As i understand it, the lower the frequency, the better the diffraction. Sure, Gamma radiation penetrates like a bullet, but doesn't travel for beans compared to lower frequency signals.

I first went down this rabbit hole when i was still in the USCG and looking to buy a piece of land in Maine. I found a couple parcels in Cutler, Maine that looked great online. Upon researching Cutler i found out that, at the time, this tiny town of 500 people was pretty high up on some potential nuclear target lists. Why? because this is where the Very-Low-Frequency radio station is that provides one-way communication to submarines in the Navy's Atlantic Fleet.

VLF is pretty wild; "VLF waves used to communicate with submarines have created an artificial bubble around the Earth that can protect it from solar flares and coronal mass ejections; this occurred through interaction with high-energy radiation particles." One of the big issues with any possibility of colonizing Mars is that it is magnetically dead and thereby has no protection from external radiation; maybe VLF could be a solution.

Investing in QTMM has lead me down many fun rabbit holes, especially regarding the electromagnetic spectrum. A quantum dot's ability to downshift an EM wave has countless applications. This is not new, but i still think it's one of the cooler applications.

Thanks for sending me back down that hole, its an interesting one.
