It is really both interesting and perplexing and the same time. You begin thinking you understand the physics of something and all of a sudden you get the sense that all you know is just a point in a sea of information, which is normally overwhelming for the human mind to grasp.

Yes, definitely. It is not a personal belief but rather a fact that no matter how much we think we know or understand, we would eventually hit a wall or fathom the physics more, marking all previous discoveries as absurd or technically false in a way. The truth is nothing is just “false”- just like the cosmological constant – they are rather essential steps to what we now know.
