So, at best the loop will gravitate toward the sheild, but the whole setup wont thurst leftward. <br /><br />also, are photons in a constant state of acceleration ? cz their refelection around the loop is not the same as angular acceleration. <br /><br />Also, what exactly does the shield do in a physical sense? Does it absorb the radiation, turning it into .... ? Does it make the area harder for something to top pop up in our world with momentum or mass ? .... can u elaborate on that part at lest for the layman ?Unknownhttps://www.blogger.com/profile/16263283568775962662noreply@blogger.comtag:blogger.com,1999:blog-4637778157419388168.post-52747705086261698342017-05-01T13:35:51.309-07:002017-05-01T13:35:51.309-07:00Mike S: Many thanks.

For some of these ideas can't you plug in the variables with comsol and determine if their is a useful effect? On an unrelated topic, I saw where it was claimed that many of the black holes are aligned. 1. Do you agree that they are and 2. If the are, what would be some of the theories that would account for that phenomena?

(lots of bounces) Basically just move the shield over the top of the device, if Unruh radiation perturbs the photons you should see a change in the interference pattern.

You'll lose half of your power after 13 times around the loop.<br /><br />(see http://www.dkphotonics.com/product/2X1-Pump-Combiner.html)<br /><br />I don't think you are going to get a Q of 10^6 from any available optical cable components. I suspect if you take a 100m cable and loop it with a diameter of 1/2 meter (200 turns) along with a good pump combiner you might get a Q of 2000 or so.<br />coldspongerhttps://www.blogger.com/profile/05583949252801148945noreply@blogger.comtag:blogger.com,1999:blog-4637778157419388168.post-54494394833163793882016-07-26T21:43:44.675-07:002016-07-26T21:43:44.675-07:00Of course it is tempting to try to find a shortcut...Of course it is tempting to try to find a shortcut in understanding chaotic and complex reality, but pondering such clearly false ideas seems like a massive waste of time to me. <br /><br />But hey!

Woodward's theory, as far as I understand it, is based on higher order effects derived from general relativity and predicts transient mass fluctuations in objects absorbing energy while accelerating, among other things.<br /><br />MiHsC is built by combining quantum mechanics and special relativity in a new way, and gets rid of the need for gravity (GR). So the two theories are very different.<br /><br />Nevertheless, some of Woodward's experiments look to me like they might be explained by MiHsC, but I haven't looked at it in detail, for various reasons.Mike McCullochhttps://www.blogger.com/profile/00985573443686082382noreply@blogger.comtag:blogger.com,1999:blog-4637778157419388168.post-3179398914724470412016-07-19T19:03:06.789-07:002016-07-19T19:03:06.789-07:00How is your theory different from Woodward's M...How is your theory different from Woodward's Mach Effect Theory?mlorreyhttps://www.blogger.com/profile/01409082009155277114noreply@blogger.comtag:blogger.com,1999:blog-4637778157419388168.post-22490322436565085602016-07-19T08:22:08.127-07:002016-07-19T08:22:08.127-07:00Alain: Unruh waves are waves in all the particles&...Alain: Unruh waves are waves in all the particles' fields.Mike McCullochhttps://www.blogger.com/profile/00985573443686082382noreply@blogger.comtag:blogger.com,1999:blog-4637778157419388168.post-22612334006197474492016-07-19T08:00:09.528-07:002016-07-19T08:00:09.528-07:00Zephir: the way I have applied MiHsC to the emdriv...Zephir: the way I have applied MiHsC to the emdrive is an approximation, but a reasonable one given the large uncertainties in the data.
