I really doubt that anything that we can observe or postulate has it's limit.

Everything has a limit... We're already starting to hit glass ceilings in science and technology. Our total perceptual inadequacy in understanding the implications of Quantum Theory and our inability to come up with a quantum theory of gravitation without are two of them. Then there's the fact that it is impossible for a human to visualise the topology of spacetime...

I know that we can't properly conceptualize quantum theory but suppose we gain that ability somehow? There would still be something beyond even that that would open into another vista of study and theorizing . . . If I may, even though it contradicts the hypothesis of the article I posted: Just because we can't properly observe something,it doesn't mean that it isn't there.

Whats being argued? Is the article up there saying that just by knowledge or understanding or thought or anything else in that whole line of stuff, we change the universe physically or how it effects us or something? I didnt read most of it.
Is it suggesting that by thought or knowledge and all that the universe exists or is it saying that thought makes up the universe and thought can change it? I hope its not saying that we can move a tree or change it by understanding our connection to the universe or with our chi or something.
Or are we arguing about proof and mathmatics in the universe?

in regards to the orginal question yes but you dont.

a glass ceiling in science makes perfect sense it stands to reason that as a species we will not be able to go beyond a certin point without evolving into somthing diffrent
