Comment: Time itself being the temporal dimensions can be manipulated by means of clever physics so as to make a time travelling domain in the backyard of your own garden. The principles of this are introduced along with physics, so as to capture the beauty of time travelling on a grander scale by some arbitrarily modified civilizations in the faraway futures. This starts with the basic notions on the perspectives of time with regards to its implications in the physics of the time travel.

In rotating homogeneous decay, the prolate quadratic form associated with the normalized Reynolds (NR-) stress is elongated by a coupling between velocity fluctuations and the Coriolis acceleration. This paper shows that this well-known turbulence phenomenon is consistent with an algebraic anisotropic prestress (APS-) closure for the NR-stress that unifies the study of turbulent flows in rotating and non-rotating frames-of-reference. The APS-closure is a non-negative mapping of the NR-stress into itself and is, thereby, universally realizable for all turbulent flows.
