The Real Tautology Great example of the video game. Even the unseen territories of the video game are consistent with the seen territories and as a whole, because they were designed that way. It's only that we observed a part of it, which does not impact the creation. But, we derive our understandings only from the things we have observed or imagined. For example, anti-matter was always in existence, but we found it later. Before the discovery, all our theories did not account for anti-matter. After the discovery, some theories would still be consistent and some might be proven false which were yet considered to be true. (Everything is true until proven false).
I like to think from the direction of nothingness. How can you arrive at the universe (or reality) as we know it today, from the state of nothingness. Everything makes a lot of sense with this POV.
