They actually are tunnels that connect to a mirror universe
where time runs backwards. Not useful for jumping light years
through the galaxy as in tons of sci-fi.
Not useful for anything and untestable. It's just an attempt to make QFT slightly less incompatible with GR by messing with the equations to
create an arrow of time since QM doesn't either need or have one. As
with GR to an observer inside of each of these mirror universes time
would still be seen as only going forwards. The only difference is that
the new equations predict greater undulations of energy density in
certain regions of space-time which are bigger and thus easier to detect
than those predicted by the existing SM, but still impossible to measure
using any instrument that exists today or that we might be able to build
in the far future.
