[QUOTE="Umbran, post: 6739275, member: 177"] I'm not treating them differently. For the Kerr black hole, or Tipler time machine, someone said, "Hm. Look at this weirdness that the math said is possible." Some folks in the science community react with, "Well, we should look for fundamental laws that will prevent that situation." I question how hard you have to look for solutions to the problem that may never happen. If someone said, "Hey, look, the math says that you can do this thing, that will only dump you outside the observable universe," I might respond similarly. This is not sweating some particular details of a theory that otherwise works pretty darned well and has many verified predictions, because they are edge cases that may never actually occur. But that's not what's happening here. Someone instead went, "Well, if I claim it is outside the observable universe, I can posit anything and consider it viable, even if it goes contrary to current observation and theory." This is basically leaning on non-falsifiability as an excuse to make stuff up. [/QUOTE]
