Sažetak
Nonlocal Bohmian mechanics can be formulated in a relativistic-covariant way by first reformulating ordinary quantum mechanics such that time is treated on an equal footing with space. This means that space probability density is generalized to spacetime probability density, and that single-time wave functions are generalized to many-time wave functions. The corresponding Bohmian spacetime particle trajectories are parameterized by an external scalar parameter that does not involve a preferred reference frame. The states of quantum field theory are represented by wave functions that depend on an infinite number of spacetime positions, leading to an infinite number of particle trajectories. The appearance of creation and destruction of a finite number of particles results from quantum theory of measurements describing entanglement with particle detectors.
