The branch is the root. Is the universe linear (flowing in time and space from beginning to end)? Can you go forward and backward in space and time? Can you step sideways out of the Universe and spacetime and look in? Yes, the Universe is all things, but what if "things" are not all there is? Is causality absolute? Does it have to be absolute if we hold that space-time is not linear? Could our universe be defined by causality and any a-causal arrangement be thought to be "outside" of the universe and outside of time? Wouldn't that be a great place for "God" to exist? How else do you create causality except from a state of non-causality? Where is the door? I want to step through.

You're asking some good questions. I'll try to answer them:
1. The Universe is not exactly linear (simultaneity is not preserved, i.e. there is no absolute time), but it does move in the general direction of from past to the future.
2. You can only go forward in time, but not backwards.
3. We currently have no real way of stepping outside the Universe and spacetime. We can only imagine it in our minds.
4. By definition, the Universe is "all there is". If there is something else, then we must included it in the definition of the Universe.
5. Causality is NOT absolute. It is well known that in the Quantum world of sub-stomic particles, it is probability that determines what happens, not causality (meaning we do not have the scenario where if A happens, then B follows. No. Even if A happens, B may or may not happen. It depends on the probability or wave functions of A and B).
6. For any being to be a creator of something, the creator must have pre-dated the something, and be outside of it. Hence, I am confident in saying that God does NOT exist in the Universe, or simply that God does not exist.
7. Stepping through that door is perhaps a one-way trip. Don't be so anxious. Enjoy your current existence awhile longer...

No, causality is not absolute.
There is a precise relationship between certainty and indeterminacy that goes to the heart pf physics. It is often called the Heisenberg Uncertainty Relation. Basically, the universe is such that certain properties of matter cannot be determined simultaneously with equal accuracy. This leads to causality being probabilistic.

Our universe is infinite, which means it has no boundary or edge. It goes on for ever.
