We have absolutely no idea whether the universe or its complexity are infinite. With that out there, it leave the possibility that no matter how much knowledge we amass, it's at best infinitesimal in comparison to all that is possible to know, and at worst, our models will be completely contradicted by some new knowledge that puts previous learning in a different context.

The set of all primes is also infinite, but that doesn't mean it's possible to find an even prime number greater than 2... the universe can be infinite but that doesn't imply the laws governing it are also infinitely varied.

My point was not to state the truth but to show the possibility. Unlike prime numbers, the historical pattern is that our model of reality has changed fundamentally several times.

An easy, however unlikely, example of what could change it again is to find out we are in a simulation.
