Like the fiber optic loop will accelerate the light ? <br />And what kind of metal structures would we need to create an artificail-horizon ?<br /><br />Thank youAnonymoushttps://www.blogger.com/profile/11479914056302172163noreply@blogger.comtag:blogger.com,1999:blog-4637778157419388168.post-45701048991455494162017-11-09T15:58:23.553-08:002017-11-09T15:58:23.553-08:00Sir,

Many years per travel, given you still are below c. <br /><br />Feasible for probes but much harder for humans that need food, water, air and supplies. Nevertheless worldships taking a city worth of people to the stars could one day become feasible, given the greatly increased cargo capacity and the growth of space activities we can expect would result in such big ships eventually being made.<br /><br />Albeit I understand Mike's theory predicts some super-luminal speeds are indeed possible, but I ignore how fast we could actually go with any feasible implementation of any technology using these phenomena.Anonymoushttps://www.blogger.com/profile/03834647512480511000noreply@blogger.comtag:blogger.com,1999:blog-4637778157419388168.post-34619971179701794792017-10-07T00:37:48.128-07:002017-10-07T00:37:48.128-07:00Unknown & AnalyticD: Indeed, to make interstel...Unknown & AnalyticD: Indeed, to make interstellar travel possible you just need to use the fuel that is out there in deep space, ie: nothing (the zpf).

So, a conductor is needed (or a mirror). Yes, superconductors would be better (more efficient cancellation of the em field).Mike McCullochhttps://www.blogger.com/profile/00985573443686082382noreply@blogger.comtag:blogger.com,1999:blog-4637778157419388168.post-73438024667663067642017-09-22T17:19:38.681-07:002017-09-22T17:19:38.681-07:00What are the ideal material characteristics of dam...What are the ideal material characteristics of damping plates? Must they be metal? Or does it matter at all with respect to shielding Unruh radiation?<br /><br />If electrical conductivity is key, would high temperature superconductive ceramic plates be better than room temperature metals?<br /><br />Or if atomic lattice density is key, then synthetic diamond (highest atomic density material) would be the thing to use.mikegemhttps://www.blogger.com/profile/06706460417030524841noreply@blogger.com
