Explanation of time travel using big bounce

We are going to see a short description on what exactly big bounce theory is and also we know that as per most of the theories, we know that time is nothing but just a 4th dimension.So there are many questions and paradoxes which occur if we talk about a thing called time travel. But today we are going to provide a solution for twin paradox and also are going to see, whether we can move into past, if yes then in which condition we will move into past i.e any year and in which condition we will move into past with respect to time moving in future i.e past wrt normal frame of reference but limited to the year in which we started traveling.

Rainbow Gravity: Big Bounce in Bianchi Type I Universe

We will examine the Bianchi Type I universe under the Rainbow Gravity formalism and calculate various quantities like the dynamical equation for the energy density and the negative energy density. Finally, we apply the analysis to a specific Rainbow Gravity model.
