  • What the laws are that govern the interactions between all those different particles, and
  • What initial conditions the Universe starts off with.

If you give a scientist all of those things and an arbitrary amount of calculational power, they can reproduce the entirety of the Universe we experience today, limited only by the quantum uncertainty inherent to our experience.
