In
Part III, we explore the possibility that, under extreme circumstances, space
may be stretched until it rips or tears.
In other words, hyperspace may provide a means to tunnel through space
and time. Although we stress that this
is still highly speculative, physicists are seriously analyzing the properties
of “wormholes”, of tunnels that link distant parts of space and time. Physicists at the California Institute of
Technology, for example, have seriously proposed the possibility of building a
time machine, containing a wormhole that connects the past with the
future. Time machines have now left the
realm of speculation and fantasy and have become legitimate fields of
scientific research.
