Are forces deteministic or probabilistic?

Question

Note Einstein did not allude to anything probabilistic.Was he right about forces warping space-time deterministically?

Answer 1

In Classical physics we have particles and their trajectories. Forces acting on the particles decide their determined trajectories. There is nothing left for chance and hence probability.

The quantum physics has no scope for point particles and their trajectories, because of the uncertainty principle which is the fundamental premise. Hence we have to talk about the probabilistic interpretation. Force is not dynamical operator hence has no quantum analogue. Forces can contribute to Quantum physics indirectly. They decide the energy and hence the Hamiltonian operator which then decides how the wave function would evolve with time. These adjectives probabilistic and deterministic do not apply to forces as such. But in the realm of particle physics there are no forces without particles and there are no particles without forces. Particles are always probabilistic in nature as far as their trajectories are concerned in quantum point of view.

Answer 2

Many forces are deterministic. Space time warping is only a mathematical explanation of gravity. Thats how explained because gravity do bend light. Other forces too. No such warping in reality except that light doesn't travel in straight line. But then none in the universe travel in straight line. So the interpretation by others are wrong not Einstein. The gravity ( or any force) causes warp by bending the light and it is deterministic. Not the other way.
