The detonation produces higher pressure and temperature, causing higher exhaust gas velocities. More energy in the exhaust means more push from the same amount of propellant. About 15% more. The other yet to be realized in practice advantage is that by eliminating the compressor stages on a rocket engine its construction is simplified, and despite needing a much stronger combustion chamber, it could actually be lighter.

If it can live up to more efficient, cheaper, and lighter then it will certainly see widespread use.

There are bound to be issues with new larger designs, but nothing show stopping is expected.

> Most companies decided to just pull diesel cars from the US market, and it turns out that all of the ones that stayed were tricking the tests in one way or another.

That's just not true. There were three options, stop selling diesels, implement a selective catalytic reduction system, cheat the test. All three were done.

>I'm actually surprised that there isn't more direct action against overly aggressive drivers.

What direction action could a cyclist take on a car driver that intentionally buzzed them while passing? I suppose if you happen to catch up to them at a light you could vandalize their car. Make a habit of doing that and you'll wind up the victim of an unfortunate accident that no one will be punished for.

> A future myth?

Yes, a story about the future that he wants to generate a collective social belief in.

Seems pretty selfish to keep all that money when he could give it back to Meta.

I think it really boils down to, they need a near future myth for investors to speculate their stock price up. That myth is, ubiquitous, always-on AR is just around the corner, and they're going to be the platform it runs on.

What percentage of the population do you think would need be hospitalized for "brutal" to be accurate?

If giving his collaborators credit diminishes his stature, then his stature must have become overblown.

You don't have to look at other industries. Other auto-manufacturers do their testing on test tracks.

Is that simply your impression, or is there trip length data to support that?

> We know what happens to matter at those speeds, it becomes infinitely "heavy" and would experience time in relative light-years (I mean time-to-travel at light speeds) no?

I don't think we do know what happens. Relativistic mass approaches infinity at exactly c. Beyond c we obviously have no data, but if we just apply the same equations the relativistic mass would drop back to a finite value. A finite complex value.

Isn't getting where you're going in less time the whole point of going fast? Why would you want to use a device that made your journey take longer?
