here's a blurb from my third e-book (incomplete)
Over the last few decades, there has been quite a bit of debate over whether such a wormhole is physically possible. The amount of energy to sustain
it, physicists argued, would be too immense and the passageway would collapse on itself in micro-seconds. However, in the last 5 years, the original
arguments have been met with new findings, such as this one, reported in BBC News on April 12, 2000:
According to Sergei Krasnikov of the Pulkovo Observatory in St Petersburg, the new wormhole can create its own abundant supply of exotic matter.
This way, the wormhole would be big enough and could stay open long enough for people to use.[2]
"What's new is that this wormhole actually generates enough to make it arbitrarily large," says Krasnikov who works at the Laboratory of
Stellar Physics.
In 2005, a new argument arose against practical wormhole usage, but was immediately contested:
Calculations by the Oregon researchers show a wormhole that combines exotic matter with semi-classical space-time would be fundamentally
unstable.
"We aren't saying you can't build a wormhole. But the ones you would like to build - the predictable ones where you can say Mr Spock will land
in New York at 2pm on this day - those look like they will fall apart," Dr Hsu said. [...]
However, there is still support for the idea of traversable wormholes in the scientific community. One physicist told BBC News there could be
problems with Hsu's and Buniy's conclusions. [...]
"Violations of the null energy condition are known to occur in a number of situations. And their argument would prohibit any violation of it,"
the scientist commented. [...]
The underlying physics of wormholes was not in doubt, the researcher argued. The real challenge was in explaining how to engineer wormholes big
enough to be of practical use. [3]
