Where did I say there’s no objective truth to the universe? Say I drew some pictures on small pieces of paper and arranged them adjacent to each other on a table, and then placed my hand flat on the table, then invited you to look. You can see pictures on the table, I then ask you whether there are any pictures under my hand. You (should) answer that you don’t know. You not knowing whether there are pictures under my hand or not does nor change the objective truth of their existence. The hand represents what we don’t know about the universe, and you (at least currently) don’t have the technology to lift it.
