“What does a physicist or an engineer mean by the speed of light?
“He means this little equation here where the speed of light is given by one over the square root of the permittivity times the permeability of the vacuum.
“So the point is, if you re-engineer those vacuum parameters, then you can make the effective speed of light higher in the engineered region.
“And so those are the solutions in General Relativity that are called wormholes. And again, this is not science fiction, it’s just right-off-the-shelf standard textbook General Relativity applications. (See Lorentzian Wormholes by Matt Visser)
“So what that means is reduced-time interstellar travel is not, as skeptics would say – ‘You can’t get from there to here.’
Advanced ET civilizations now, or ourselves in the future, are not fundamentally constrained by physical principles. The exotic physics for such can be addressed in engineering terms, so-called, metric-engineering, as it were.
“Again, by the way, this paper was also published as one of the Defense Intelligence Reference Documents. And since we are permitted to publish in the open literature, I published that paper in a British interplanetary science journal, an engineering journal.
“So if you’re interested in looking at the details, you can learn as much as you want to know about metric engineering.” – Hal Puttoff, PhD
