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.
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. |

If a radio wave is sent into one of these black holes, where does the signal go?
Shouldn't that have been: "Everything is looking good Zotarc, hold muh glortch juice and I'll add the ghost radiation......oh sheeeete....". boom
Humpf!! With our luck the darn wormhole will lead right to the White House.

The difference between a black hole
and a wormhole is significant. The
black hole has collapsed matter in it
that a traveller would have to get through
before going anywhere. How a black
hole can be a source of wormholes
is problematic.
Does this mean our universe is the result of a "hold muh beer" incident at a cosmic kegger? 'Twould be truly apropos!
Music lovers have been asking the programming Einsteins at Clear Channel Radio for years about a similar phenomenon.
CC uses radio waves to create black holes where audiences used to be.
Of course, they couldn't do it without the never ending supply of no talent from the RIAA either. And Mr. Powell of the FCC.
Actually socks are mearly the larval form of coathangers. [:<)
Wormhole detector: Why not attach a tiny camera to a contact lens? Let it fall, and the lens will find any wormhole within one light year and fly through it.
No, still just something that falls out of the equations.
No, coathangers come from paper clips.
Then they turn into bicycles...
