I object to calling it "just an optical illusion"! | simonh wrote: | They're not calling the veil model an optical illusion, | they're just saying that the loop like structures we think we | see are deceptively limited side effects of some aspects of | the veil structures. It's the image that's the illusion, | because it misleads us about the reality. ___________________________________________________________________ (page generated 2022-06-29 23:00 UTC)
