One could even make the argument that finding the theory of everything (often called “unified field theory”) is just the start of the real science. The theory of everything (TOE) will finally tie together all of the fundamental forces, describe the behavior of every type of particle, and explain in fine detail how space and time behave in all cases. We’ve seen unifying theories before (not the unifying theory) and they don’t generally answer questions on their own, but merely provide tools to explain things later on down the line. So, a theory of everything, while it would be able to describe the details of how all forces and particles interact on all levels, would still only be a set of equations. And having the equations is pretty different from having the solutions to those equations, and really different from understanding the implications of those solutions.
