I have a question about the fourth dimension?

Question

do you think we could use stellar energy to go back in time?

do you think we'll be able to speak, instead of travel, through time?

Answer 1

maybe the forth dimension is the paranormal. if spirits and ghosts exist, they are probably in the 4th dimension.

Answer 2

One cannot go back in time. "Moving" in time is an unfortunate concept, because time is not something that one moves through in anyway the same sense that one moves through space because it isn't a spatial dimension. It is like asking whether one can move through sound.
