There is no universally agreed-upon set of "two fundamental questions of physics." The field is vast and complex, with many interconnected questions driving research. However, two questions that are often considered foundational and encompass many other subfields are:

1. What are the fundamental constituents of the universe and how do they interact? This question delves into the nature of matter and energy, exploring particles, forces, and the very fabric of spacetime. It encompasses areas like particle physics, cosmology, and quantum mechanics.

2. How did the universe begin and how will it end? This question probes the origins and fate of the universe, exploring topics like the Big Bang, dark matter, dark energy, and the evolution of stars and galaxies. It connects to fields like cosmology, astrophysics, and general relativity.

These two questions are not mutually exclusive. They are deeply intertwined and drive much of the research in physics. Moreover, there are other crucial questions, like the nature of consciousness and the possibility of time travel, which further expand the scope of inquiry.

Ultimately, the "two fundamental questions" are not fixed, but rather a reflection of the ever-evolving nature of physics and the human desire to understand the universe around us.
