Could the Black Lodge actually be the physical plane?
This may be too off-topic, but while we're talking about lodges, and on what plane they exist...
Something I've read online (in articles and on fan forums) is that one reason Major Briggs may not have aged in 25 years is because he was in the White Lodge.
Now, I'm not sure why it would be assumed he was in the White Lodge and not the Black Lodge (though I'll admit to not being an A+ fan, so my knowledge may be lacking), but regardless of that, it's been shown that people age in both lodges. The Giant (????) has aged in the White Lodge, while Cooper, Laura, etc. have aged in the Black Lodge.
So... why use the lodge(s) as a reasoning for not aging?
