Casimir effe...Innovations for better space travel.<br /><br />Casimir effect is traditionally demonstrated by placing two extremely thin plates extremely close <br />to each other (mere micrometers apart) and letting them spontaneously slam together. But that <br />they slam together destroys the practical usefulness. To use Casimir effect practically, such as <br />tapping vacuum energy or manipulating the vacuum itself, it is necessary to keep the Casimir <br />effect Casimir. Therefore the plates should either be magnetized in such a way that they repel <br />each other or be held on one or two sides mechanically in a way that leaves the space between <br />them free. Another possibility is to use solid objects honeycombed with microholes or <br />microchannels instead of plates. It is also possible to use cylinders inside cylinders, but that <br />would have to be many cylinders inside one another to have a strong effect (lots of layers) The <br />resulting stable Casimir device can be used practically, such as for cheap spacelaunches. It is also possible to simply place capacitors in a vacuum.Martin J Sallberghttps://www.blogger.com/profile/10035778878058556742noreply@blogger.comtag:blogger.com,1999:blog-1213372485142495383.post-70323166203241902122011-08-12T14:16:28.184-05:002011-08-12T14:16:28.184-05:00String theory (and all other theories involving hi...String theory (and all other theories involving hidden dimensions)<br /> predict that gravity and electromagnetism unify in hidden <br />dimensions and that the hidden dimensions are indetectible because of <br />their small size. It does also predict that sufficiently short-waved <br />photons, with wavelengths shorter than the size of the hidden <br />dimensions, can enter them. Producing ultra-short photons can thus <br />manipulate gravity, with revolutionizing space travel applications such <br />as cheap anti-gravity launches. The <br />problem that it would require high energy can be practically solved by <br />concentrating several laser beams on a nanoparticle, heating it to <br />locally extreme temperatures. An Alcubierre metric can be created by <br />ejecting multiple nanoparticles from the craft and then beam perfectly <br />timed laser beams on them (fire at the most distant first so that they are<br /> hit simultaneously), so each nanoparticle contributes a slower than <br />light effect but together add up to faster than light, creating no discrete <br />event horizon and thus no Hawking radiation.Martin J Sallberghttps://www.blogger.com/profile/10035778878058556742noreply@blogger.comtag:blogger.com,1999:blog-1213372485142495383.post-72821379764692092182010-08-08T13:51:33.558-05:002010-08-08T13:51:33.558-05:00Maybe the thinking comes from observing nature - n...Maybe the thinking comes from observing nature - nature tends to favor energy conservation ("tends" being the operative word). This tendency is widespread and so it is not unreasonable to think that it may be a tendency for other worlds; that is, that other beings would work toward energy use in their advancements in technology. Now it is true that when you insert sentient beings into the equation, all bets may be off. <br /><br />So, while we cannot use ourselves as a template for all other beings, we also cannot just disregard ourselves as an example for at least some other beings. In a very large (if not infinite) universe, there will be others that, if not like us, close enough that we can see parallels.David M.

If true, then one way to find ETs is to investigate black holes - like observing an oasis in a desert (since most caravans will make it a point to visit the oasis during their long treks).David M.
