Overall he puts a case worth consideration as it could explain how the distance problem is solved and some possible observable effects of such a technology. Bravo.
This merits some clarification: the distance problem has been solved for decades - any form of gravitational field propulsion will do the trick. Expoiting the Alcubierre metric, you could leap to the Andromeda galaxy and be back in time for dinner, if you could generate a steep enough dipolar gravitational field gradient. Heck - if you're willing to jump forward in time with respect to your departure point, any relativistic travel will get the job done: at an acceleration of just 1g, you can circumnavigate the visible universe in your own lifetime due to on-board time dilation, but the Earth would be a cold cinder by the time you get back.
Honestly, the fact that people still think that there
is a distance problem, is a chilling testament to the enormous inertia in the public's understanding of physics. Even special relativity tells us that it's possible to travel to Alpha Centauri and back within in a few weeks of on-board flight time, but the Earth will have aged more than eight years when you get back. You actually have to go all the way back to Newtonian physics before you run up against the now-completely-debunked concept that you can't get anywhere faster than the speed of light (8+ years to Alpha Centauri and back, for example) - and we've known for over a century that Newtonian physics gives us the wrong answers in these kinds of scenarios. And with general relativity, there are no time/distance limitations whatsoever: the only limitations with GR lie with your technological capability to distort the spacetime metric. So in practice, according to GR, it's theoretically possible for a craft to visit the Earth from beyond the horizon of the observable universe, and return within a week, or even a day, with respect to your launch point - and you won't even feel any acceleration in transit.
So we already have the theoretical physics to permit superluminal travel like we've seen in Star Trek - the only thing that's holding us back is the limitation of our modern technology.
There are reports of UFOs, we can say the reports exist, but then there are also reports of fairies and Bigfoot. No evidence exists to prove UFOs are real as a physical phenomenon. Sorry dude.
You're mixing up your terminology here: there's
a vast body of evidence that UFOs exist, and that they've been prancing about our airspace for over 70 years: myriad credible eyewitness reports, radar-visual cases, trace evidence cases, and of course the enormous body of evidence collected by the DoD, of which we've only recently been permitted the most fleeting and ambiguous little glimpses. Thanks in part to Luis Elizondo's break from routine protocol, we now have a pretty clear idea of the actual extent of the evidence that the DoD has collected in recent years, and what he's seen as director of the AATIP is apparently well beyond "a reasonable doubt."
But okay - we plebes in the public sector haven't had the privilege of seeing what he's seen, thanks to the excessive secrecy of the US government. We still have an abundance of evidence. But that's still not equivalent to "scientific proof," which is an
altogether different issue. The DoD clearly has sufficient evidence to constitute "proof." But the public? No, not really. The really clear and compelling evidence has been collected by the US military, and they're not sharing (except for a few brief blurry clips which prove nothing).
But for those of us who have seen these devices perform totally unearthly inertia-defying maneuvers, it's already essentially proven to us. Because 70 years after people started reporting sightings of exotic devices zig-zagging through the sky at thousands of miles per hour, as I've seen and many others as well, even the most cutting-edge modern military jets can't even come close to those kinds of maneuvers, because it takes
applied general relativity to achieve those kinds of performance characteristics, and we still don't even have a plausible conceptual approach to get there. But we can and will get there, because these devices operating in our airspace prove that it's possible. So it's only a matter of time before we figure it out. And in my opinion, that's probably why they're here, and monitoring our progress - think about what we're doing to Syria right now, and then imagine what we might do when we discover the technique for superluminal spaceflight so we can reach inhabited alien worlds. If I were a neighboring alien civilization, I'd be deeply concerned about that. And I'd be as covert as possible with my monitoring efforts. Because until we wrest control of our military apparatus away from the sociopathic war profiteers, human civilization as it is today poses an existential threat to every form of life in the galaxy, including our own.
