Quantum wormholes could carry people

All around us are tiny doors that lead to the rest of the Universe.
Predicted by Einstein's equations, these quantum wormholes offer a
faster-than-light short cut to the rest of the cosmos - at least in
principle. Now physicists believe they could open these doors wide
enough to allow someone to travel through.
Quantum wormholes are thought to be much smaller than even protons and
electrons, and until now no one has modelled what happens when something
passes through one. So Sean Hayward at Ewha Womans University in Korea
and Hisa-aki Shinkai at the Riken Institute of Physical and Chemical
Research in Japan decided to do the sums.
They have found that any matter travelling through adds positive energy
to the wormhole. That unexpectedly collapses it into a black hole, a
supermassive region with a gravitational pull so strong not even light
can escape.
But there's a way to stop any would-be traveller being crushed into
oblivion. And it lies with a strange energy field nicknamed "ghost
radiation". Predicted by quantum theory, ghost radiation is a negative
energy field that dampens normal positive energy. Similar effects have
been shown experimentally to exist.
Delicate balance
Ghost radiation could therefore be used to offset the positive energy
of the travelling matter, the researchers have found. Add just the right
amount and it should be possible to prevent the wormhole collapsing - a
lot more and the wormhole could be widened just enough for someone to
pass through.
It would be a delicate operation, however. Add too much negative energy,
the scientists discovered, and the wormhole will briefly explode into a
new universe that expands at the speed of light, much as astrophysicists
say ours did immediately after the big bang.
For now, such space travel remains in the realm of thought experiments.
The CERN Large Hadron Collider in Switzerland is expected to generate
one mini-black hole per second, a potential source of wormholes through
which physicists could try to send quantum-sized particles.
But sending a person would be another thing. To keep the wormhole open
wide enough would take a negative field equivalent to the energy that
would be liberated by converting the mass of Jupiter.
