Temporal Stasis
Shifting an object inward through the fifth dimension causes the object to experience less time in each temporal cycle. This has the practical effect of slowing down the aging process of the object.
To understand the effects of such temporal stasis, assume that a person (call her Ms. Still) has a fifth-dimensional temporal stasis field generator with an effect radius of two meters and a temporal dilation ratio of one-to-thirty compared with the rest of the world. That would mean that while within the stasis field her wrist watch would record the passage of only one minute for every thirty minutes recorded by a wall clock across the room.
The effects of temporal stasis are exactly opposite those of temporal acceleration as discussed above. Ms. Still's inertial mass will increase thirty times, making it very difficult to start or stop moving, or to change direction. Also, from her slowed perception, objects would seem to fall thirty times faster; an object that normally takes one second to fall to the ground would take only one-thirtieth of a second to fall according to her watch.
Likewise, light entering the stasis field would shorten in wavelength, becoming blue-shifted, so everything on the outside will seem to have a bluish tint in Ms. Still's perception. But while she experiences only one minute of time, thirty minutes worth of light energy will have entered her stasis field from the outside, making everything on the outside seem much brighter to her.
Due to the increase in her perception of gravity, Ms. Still would not be able to walk while in the stasis field; in fact, she might be crushed by the increased gravity even while lying on a bed. It is therefore necessary for people and other fragile objects within strong stasis fields to be suspended in a tank of liquid or gel, so that they are not crushed by gravity. These tanks, known a tempostats, would also shield them from the thirty times more light and radiation from the outside to which they would otherwise be exposed.
Despite these harmful physical effects, in a properly constructed tempostat, with an oxygen supply, a person could survive in temporal stasis with a ratio of up to one-to-one thousand (i.e., the person in stasis would age one year for every thousand years that passed in the outside world). Solid inanimate objects can be subjected to even stronger temporal stasis fields, aging just one year for every hundred thousand or even million years that passed in the outside world.
Aside from its preservative effects, temporal stasis technology has a variety of other uses. A tempostatic grenade with an effect radius of three or four meters could incapacitate an enemy on the battlefield, both by slowing him down and by increasing his relative gravity and inertial mass.
