Physics Explains How to Build a Time Machine Using This Simple Construction
Until recently, most studies on time travel are based upon classical general relativity. Coming up with a quantum version of time travel requires us to figure out the time evolution equations for density states in the presence of closed timelike curves CTC. Novikov  had conjectured that once quantum mechanics is taken into account, self-consistent solutions always exist for all time machine configurations, and initial conditions. However, it has been noted such solutions are not unique in general, in violation of determinism , unitarity and linearity. The application of self-consistency to quantum mechanical time machines has taken two main routes. Novikov's rule applied to the density matrix itself gives the Deutsch prescription.

Travelling forwards in time is surprisingly easy. If one were to leave Earth in a spacecraft travelling at an appreciable fraction of lightspeed, turn around and come back, only a few years might have passed on board but many years could have gone by on Earth. It allows for the possibility of wormholes — a kind of tunnel through spacetime connecting otherwise very distant parts of the universe.
