Advanced alien civilizations know the techniques of coexisting in many time dimensions

Time is multidimensional. Any type III and above civilization can coexist in multiple time dimensions through the use of integrated consciousness.
Advanced alien civilizations know the techniques of coexisting in many time dimensions at the same time and go back and forth. That is the essence of immortality. Once a civilization can seperate the existence between physical entity and spiritual or eternal entity through the use of particle physics and multidimentional gravity radiation techniques, they can achieve the status of type III civilization.

Computer algorithms can model multiple time dimensions and an entity in the physical universe can be seen in the model to coexist simultaneously in many time dimensions.

Advanced alien civilizations can live their own life in the alien world and at the same time they can travel to a distant place in space using a different time axis.

Once we master this technology, we will literally be able to create multiples of us working different things at the same time.
