This is unsurprising. I doubt there was anyone with a modicum of understanding of the physics (even the teams doing the testing) who expected it to work. That doesn't, however, mean that testing it was a waste of time. There was an anomalous result that has now been resolved. I think it's a vital scientific virtue to follow up anomalous results until they're satisfactorily resolved, no matter how ridiculous or physics-defying they seem.

The EmDrive was always a long shot, but it wasn't the only reactionless drive under investigation. Unlike the EmDrive, which never had a plausible physical mechanism for how it could work, the Woodward Effect [0] does have such a mechanism and has yet to be experimentally disproven. It exists in this weird place where it seems to be a straightforward theoretical prediction from general relativity; where, almost by exploiting a loophole in physics, the maths says you can get thrust without propellant, and much more of it than possible with a photon rocket for the same power. This, apparently, doesn't violate conservation of momentum, either, because the momentum would be carried by gravity waves, essentially "pushing" against distant masses throughout the universe. Whether this is actually predicted by general relativity or is a misapplication of the theory, is very subtle and not something I'm capable of evaluating.

This is being evaluated by NASA [1] -- not that that says very much, NASA will evaluate some pretty crazy things, see exhibit…

>GDP and GDP PPP both quantify production, not income and living standard metrics.

Purchasing power parity (PPP) allows for economists to compare economic productivity and standards of living between countries.

>Countries can have cutting edge industries AND still lag behind in development - Brazil (Defense, Aerospace, ONG, Automotive), South Africa (Defense), Turkey (Defense, Automotive, ONG), Mexico (Defense, Automotive, ONG), Russia (ONG, Defense, Aerospace, Automotive), Malaysia (Automotive, ONG, Electronics), etc are all countries that are major innovators and even leaders in STEM/innovtion heavy industries, yet still have significant issues with spreading development across their countries. The PRC is facing a similar issue, and it is a hard nut to crack - I can't think of a single middle income to upper income economy that didn't also

Brazil does not lead in Aerospace, ONG, Automotive. South Africa does not lead in defense. And so on. They do not possess technology that other countries depend on. For example, Embraer's revenue in 2021 was 4.2 billion. Puny compared to Airbus' 52 billion. If Embraer stopped operating tomorrow, the world would not notice.

We're talking about actual innovation and a technology advantage. You mentioned that Mexico leads in automotive. What? Mexico does not have any cutting edge automotive technology that other nations depend on. Mexico is a hub for car manufacturing…

I understand what it means. What I'm asking for is a credible source that predicts how this would happen. None of your sources come close. Let's see...

A dire revenue warning for the non-farmed shellfish industry:

"Sarah Cooley studies the socioeconomic impacts of altered oceans at Woods Hole Oceanographic Institution in Massachusetts. She and other researchers project acidification could reduce U.S. shellfish harvests by as much as 25 percent over the next 50 years."

Jellyfish Apocalypse? Postponed until further notice:

"Many citations of this paper assume that she found conclusive proof that the jelly apocalypse was happening. This dangerously bad science got so out of hand that during a conference in 2011, over half the scientists in attendance said that the jelly apocalypse is happening. Mills herself was at the event, and she voted no. Since then, many scientists have gone over the data with a fine toothcomb and concluded that the data could be misinterpreted as an increase in jelly numbers. Marina Sanz-Martin was one of these scientists, and she concluded that others had manipulated the data to get…

This is an abstract of an article behind a paywall so we can't see this details but it is from 2021 and I managed to find an article discussing the concept [1]

> In this case negative energy is not required — rather it’s gravity itself which bends spacetime and gives rise to time dilation. In essence the gravitational field makes the passage of time within the passenger area much slower than the passage of time outside of it. A few minutes for them may be thousands of years worth of space travel, yet to leverage this powerful effect would take enormous amounts of gravity. The paper calls for the compression of an entire planet down to just a thin shell surrounding the passengers. The introduction of a physical warp drive model has changed the question from “Does something like negative energy even exist?” to “How do we compress the mass of a planet down to the size of a spaceship?”

And I'll pull out the most apropos sentence:

> The paper calls for the compression of an entire planet down to just a thin shell surrounding the passengers

Yes, no negative energy or negative energy mass, just an entire planet compressed into a thin shell that somehow doesn't further collapse.

So even if this were possible, how would you accelerate or maneuver such a massive object?

I've seen so many of these proposals over the years. It's all nuclear-grade hopium with a massive flaw or huge, highly theoretical unknown. Always.

You are referring to the 1970 MIT LtG model which was updated in 2019 and still predicts a global collapse?

Or the depleted global fish stocks?

Or the fact that if everyone went vegetarian we could free up 80% of the farmland in the world?

Whilst resource are not fixed, like lab grown meats, supplements which can alter people's diets like histidine will reduce red meat consumption, I am aware some businesses have also kept some resources under wraps from the public so I agree they are not a fixed notion, but in ten years the US lifestyle has increased its use of resource from 4 planet earths to just over 5 planet earths.

Sure anything can be a resource, we might even be able to use plate tectonics as landfill waste disposal because everything came from this planet so is technically from the Earth, and who knows what resources could be mined from the planets core, or do we get into mining Helium13 from the moon?

there is a still a problem and that is quality of life, being kept in smaller more expensive livestock pens called homes.

What price do you put on having rolling pastures all around your home and no manmade noise around you?

With a global population set to peak in 2100, we still have 80's years of declining quality of life to put up with.

It’s not only people moving further inland. It’s people moving from places that are hot now, and unlivable hot soon. And the movement will continue for several decades, but i wouldn’t be shocked to see a hundred million people move in one year before 2050. Minimize it all you want, it’s going to happen and you will be impacted by it if you live long enough to see it.

As for your snarky “citation needed” - this is all easily googlable stuff. I’d start with understanding what “trophic collapse” means.
