I'll add more about this to my answer soon, but do an image search and note how some charged particles are conveniently siphoned down the earth's poles, as well as how the trailing magnetic field forms a nice large shadow behind it. | |

| Mar 12, 2019 at 2:53 | comment | added | zchrykng | @BoomChuck Thanks for the great answer. Let me toss out how I was envisioning it to work and maybe you can poke some holes in it. :) Basically, I was thinking of the object being pretty small, small enough to be unlikely to be visible against the backdrop of the Sun. The idea would be that it would be collecting some amount of magical energy and using that keep itself in place while creating a bubble of non-magical space around Earth and the Moon. Something like the what you see when a flow of water strikes a smooth convex surface. | |

| Mar 11, 2019 at 23:24 | comment | added | user35577 | @BoomChuck Could incoming sunwind be gathered as a propellant gas, and photovoltaic light blocking swarm of replicating magnetoplasmadynamic bots ionise this gas in order to autonomously and actively keep station? Bussard collector like | |
| Mar 11, 2019 at 23:23 | comment | added | BoomChuck | @Ben sorry no, I pulled the idea off the top of my brain. a quick googlin found tons of fascinatingly dry technical research papers. so scientists are working on it, but they haven't been able to un-boring it yet. | |
| Mar 11, 2019 at 23:15 | comment | added | BoomChuck | @Gene unless the particles are very weakly interacting like neutrinos, they will be heavily scattered throughout the sun as they try to escape the core. photons bounce around like a pinball machine for a remarkably long time before escaping to space. and the thing about weakly interacting particles is that they don't do much fun stuff at all :) | |
| Mar 11, 2019 at 23:06 | comment | added | ben | Cool, didn't consider the balancing of SRP inside the L1 point! Have you come across any work that examines the feasibility? I mean it seems plausible but this made me curious about the details. | |
| Mar 11, 2019 at 22:35 | comment | added | Gene | The size problem could be greatly mitigated by having the magicles/magicons be a) generated at a small area at the center of the Sun's core, and b) not interact at all with the surrounding solar atmosphere. The we would have a point magic source, which will be far easier to shield the Earth from (and get easier the closer to the sun you are, rather than harder like light shielding.) | |
