Do Theories Have to be Testable to be Scientific?
"Daniel Prince" wrote in message ... "Steve Harris" wrote: Unless of course it contains time machines, FTL drives, force-field "shields", antigravity, Wesley Crusher, or workable libertarian utopias. 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). Sure enough. Not too practical for ships or stations for particles that are coming with energies found in nature (ie, from the sun), because fields strong enough to protect things that small are very hard to generate. But it's possible in theory, and of course it works fine for really, really big fields (ie, the Earth's field). Not that humans have any idea how to generate that size field either. Or even really know for sure how the Earth does it. |
