If we ever fully understood quantum science and all there is to know about it, could one say we then fully understand the universe? Or, would we never know at which point we know all there is to know? Would you be comfortable in the belief or proof nothing more could be discovered--about anything? Should we expect to discover yet another layer of something, deeper than the quanta? To some people, it would be pretty cool if humans could understand their existence, or lack of it. Pardon me if this question is does not belong. It's my first. Thanks all.
