Good point about epistemology and ontology. - but then again I have no formal philosophical training...I just muddle by the best I can :-)
Well, I don't have formal training either. I am self educated, and do plenty muddling of my own. I'm just smart. :P
But I am interested in if you believe that we can measure anything - let's call it physical - that lies outside the boundary of the universe (the known space-time continuum we apparently inhabit).
Well, we can debate how "boundary" would apply to the universe, but that aside... It depends somewhat on what you mean by "universe." It is possible the known universe exists as a p-brane or something in a supervening universe. I generally use "Universe" (with a capital) to mean "all of existence," which would include the supervening universe, and so anything defined to be outside the Universe would be defined out of existence.
In the case of multiple p-branes/universes, I'm inclined to think that, yes, we could measure/observe things "outside." Is it possible that things existing outside our universe could be incapable of interacting with our universe even in principle? Perhaps, but if something can and does interact, then that would leave evidence, and be observable.
Indeed, we did. The forum is somewhat limited, unfortunately.
About testing M-theory @ LHC, I think the point is that it can be tested at all. Of course, what we find may not rule out string theory, but Smolin's argument is only valid if it could never even be tested in principle. This is simply not so.
About observation... We know much of what we know without any direct observation. Much of it is by inference from observational evidence, rather than observation itself. Philosophically speaking, I think "observation" is used more loosely. When your definition of "universe" includes observables (and is restricted to such), your definition of observables becomes important. There are any number of arguments, many of which will lead into metaphysical claims, which imply the existence of things which do not fit into your conception of a universe. Do you reject metaphysical claims as being without content? I wonder if you're making the common mistake of conflating epistemology and ontology.
This Western Canadian Rammstein fan is just fine. Thank you for asking. I really (really) like your "molecule" photo. One of my favourites as a schematic of ATP. I didn't upload it here because it came from a text and they didn't give me rights to the image. Where did you get your molecule?
lol, I live in middletown!!! Small world I guess! I just moved here a couple weeks ago, and have been staying with my friend in Middletown. I'm moving over to an apartment in J-town on the first :D Such excitement in my life! Six Flags over Jesus is nearby here. As an atheist, I was convinced I moved to the wrong area of the U.S. I've never, in my life, have seen a church that big.
Nice to meet you :) That blog made me understand why someone at the nexus calls himself the "call of brenthulu" lol...and to think I have read Lovecraft indeed (just the color that came from space though)...sheesh...
I'm native Atlantan, so better manners keep me from praising my hometown too much. I moved back from Portland, Oregon a while ago and the cities don't really compare in many ways. But if you're lookin' to fight the good fight for better communities in the South, then this is a good place to find comrades.
As an aside, amateur astronomy is kinda tricky here with all the light pollution. I'm happy to see fireflies, much less stars!
