Perhaps you've not yet done enough psychedelics to fragment such doubt... lol.
Can't recall specific theories or teachers at the moment, though stuff like this kinda begins to graze the comparative concept brought up...
MUCH to be explored at the intersection of fields like string theory and neuroscience/brainwaves that isn't even yet begun to being talked about in mainstream circles. Keep an eye out for @core when he starts posting...
Haha, you are right on the psychedelics front! There's a lot to read there - thanks for sharing. I do feel this is more the realm of philosophy than physics at this stage though.
