Do Theories Have to be Testable to be Scientific?
"Lawson English" wrote in message ... "Daniel Prince" wrote in message ...

Then it's okay to laugh all you like. g. There is one type of force-field "shield" that is possible. It is a magnetic field that can shield a ship or station against certain types of radiation (charged particles only). -- Actually, there is already a force field in use that acts as an air valve (plasma valve). I see no reason why you couldn't create such shields of any arbitrary power (e.g., Star Trek's deflector shields), except, of course, that the power requirements would be beyond insane. That used to be said concerning computing power. Now I can carry the portable equivalent of a UNIVAC to my seat on the airplane in my knapsack (with wireless networking and a nice color LCD monitor built in). http://www.fourmilab.ch/documents/univac/case1107.html |
