So you want to stop time

TL;DR

This paper explores a theoretical model of a stasis chamber within classical general relativity that can arbitrarily slow down time inside, comparing it to relativistic effects and discussing its practical implications.

Contribution

It introduces a model based on Majumdar-Papapetrou spacetime for a static stasis chamber capable of extreme time dilation within classical GR.

Findings

Interior spatial volume expands with time dilation factor

Real and gravitational forces are altered oppositely inside the chamber

Usefulness is limited to extreme time slowing or avoiding acceleration

Abstract

A model of a stasis chamber, slowing the passage of time in its interior down to arbitrarily small rates relative to the outside world, is considered within classical general relativity. Since the model is adapted from the Majumdar-Papapetrou spacetime, interior spatial volumes are expanded by the same factor (cubed) as the rate of time is reduced. Real and apparent (gravitational) forces as perceived by an interior observer are altered, but in opposite ways. Comparison with special-relativistic time dilation shows the use of such a static stasis chamber to be economical only when the most drastic slowing of time relative to the outside world is desired (d(tau)/dt < 10^{-20}) or when one wants to avoid spending the time needed to accelerate to relativistic speeds.
