How's that possible? Simple, actually. Time travel.
Yep, you read that right, and nope, this article wasn't published on April Fool's Day. And what's more, the notion comes from a high-profile science celebrity with his own undisputed set of credentials, such as his tenure as a professor in Manchester and years of supercollider research in Chicago and Hamburg.
Cox has apparently found a wrinkle in Einstein's theory of relativity that would enable a trip from Los Angeles to Sydney to take place via a time warp. In this case, the conduit wouldn't be across the sky or in low earth orbit, but literally through the planet.
Geometry Gets Warped
In a recent appearance on podcast The Joe Rogan Experience, Cox said this mode of travel would require a wormhole that's mathematically possible. The equation uses what he calls "warp drive geometry" to plot the end points as well as measuring what's travelling through such a tunnel.
“A wormhole would be, quite literally, so you fly from Australia to LA by going quite long way around the edge of the Earth, or you can tunnel straight through and get there quicker," said Cox, a host of a number of television programs like Forces of Nature and Human Universe, airing on the BBC.
“So you could go all the way around the edge, or take this shortcut – you can do it with Einstein’s theory.”
Don't Wanna Get Crushed
But before you pack your bags to check out all the kangaroos and Tasmanian devils in Oz, Cox offered a caveat. First, he admitted to Rogan that while his theory is sound on paper, the infrastructure to make such a trip happen won't be available for a while. Topping that list is a time machine that would work within predetermined geometric parameters.
Second, Cox warned that a trip of that sort would be fatal until science comes up with more answers. It turns out that while those calculations are sound, part of the equation reveals that anything or anyone traveling through the wormhole might cause that conduit to collapse and crush whatever's inside. Cox believes that a quantum theory of gravity would solve that problem, except no one's come up with such a concept yet.
Suddenly, spending nearly 15 hours in a sardine can with wings sounds attractive now, doesn't it?
