What are the time travel formulas used to calculate the feasibility and mechanics of traveling through time?

Time travel formulas are theoretical equations that attempt to calculate the feasibility and mechanics of traveling through time. Some of the key formulas include the Lorentz transformation for time dilation, the Einstein field equations for general relativity, and the Wheeler-DeWitt equation for quantum gravity. These formulas are used by physicists to explore the possibilities and constraints of time travel.
