I think your head can be protected from hurt if you consider the proof by Gödel that no logical system can be both complete and internally consistent. Thus we shouldn't expect our mental logical system to be able to deal with everything without throwing up the odd paradox.
If you like thinking about such things, I recommend that you look at the book Gödel, Escher, Bach: the eternal golden braid by Douglas Hofstadter.

My favorite head-hurting concept regarding origin of the universe theories...
If this 4-D space (more like 11-D if you want to get technical about it) in which we find ourselves has a starting point (like the big bang), then what caused that to happen?
Unless you believe in A-Causality, something had to start it.
Now, time, as understood in modern physics, is a component of the fabric of space-time that defines this 4-D space.
However, if something caused this 4-D space to come into existence - well, that was an action. For any action to actually happen, there must be some sort of time.
This implies some sort of time that exists outside of the fabric of space-time that defines our 4-D space.
This implies more than one dimension of time! Multiple dimensions of time would allow for (but not require) all sorts of time-travel and cross-time communication scenarios. We could have apparent breaks in causality (to those inside the inner dimension of time) such as the grandfather paradox, but would not have true breaks in causality.
Fun stuff.
