| Apr 13, 2019 at 19:36 | comment | added | peterh | @Muze I think a liquid metal shield, whose form is controlled diamagnetically, could work. | |
| Apr 13, 2019 at 19:24 | comment | added | Muze | @peterh is it practical though? Hobbies answer makes a good point. I would like to see some of your answers. I have some questions that have no answers. And thank you for advocating. | |
| Apr 13, 2019 at 19:08 | comment | added | peterh | @OrganicMarble I admit that it is far over the current technological possibilities, and it is questionable that it would be the better as the possible alternatives. But, I also can't see any essential reason why it could not work. | |

| Apr 13, 2019 at 17:40 | comment | added | Organic Marble | @peterh got any calculations or references to back that up? I can imagine a lot of things, but that doesn't mean they are worth anything, without putting in the work. youtube.com/watch?v=rZBHits8JPI | |

| Apr 13, 2019 at 15:26 | comment | added | peterh | @Uwe I think although liquid iron would radiate intensively, this radiation (1500C) would be far lesser than the Sun's (6000K). Although it wouldn't be ferromagnetic, but it could be still manipulated on diamagnetic ways. | |

| Apr 13, 2019 at 10:21 | comment | added | Uwe | A hot molten metal like iron would not deliver a good cool shadow. It would radiate intensively in the infrared and visible spectrum. If it's temperature is in steady state, it will radiate away all that energy received from the sun. The spacecraft would need a heatshield against the radiation of the liquid metal. | |

| Apr 13, 2019 at 9:30 | comment | added | Rory Alsop♦ | Why do you say unattached but needing to exert force? And why would you want to transport it near the sun? What is it you are trying to achieve? | |
| Apr 13, 2019 at 7:54 | comment | added | Hobbes | the question is, why would you want your material to be in a liquid state and unattached? It'd be much easier to have the material as a solid, in panels on the outside of the hull if you want to use it as shielding. | |
