I envision a future where fields are filled with these black holes and an area of a couple of square kilometers is completely and utterly blacked out.
Really adds drama to the post-apocalyptic scene.
- arketyp 17y agoI'm trying to imagine the optical effect of looking at such a device. Maybe I'm misunderstanding the physics, but if it's anything like that picture it must be quite a fascinating distortion of the visual scene. Not only completely black at the center but also a very strange surrounding.
- hugothefrog 17y agoI'm not sure. Wouldn't the angle of refraction (into the core) depend on the angle of incidence of the light hitting the device?
- jacquesm 17y agoTwo notes: 1) it will be 'visible' in other spectra than the one absorbed 2) it would have to be, otherwise even the smallest inbound radiation would melt the thing eventually.
- DougBTX 17y agoOne goal will be to produce electricity instead of heat.
- jacquesm 17y agoYes, but even that is going to have to be either moved 'off site' generating an electromagnetic signature somehow, at a minimum some infrared because of line losses, or consumed on the spot, in which case it all comes back out as IR. It is really terribly difficult to 'get rid' of anything without a trace.
- yummyfajitas 17y agoThe device will look like a slab with a distinguished direction (say the Z direction). Suppose the black hole is at (x, y) = (0,0), z=anything. If you shine a laser/microwaves/whatever the relevant frequency in at one side, it will always come out of the slab near (0,0). Basically, laser beams shined into the slab will be attracted to the line x=0,y=0, z = anything. [edit: really curious why I'm getting downmodded. Did I wildly misunderstand the device?]
