One aspect which causes concern is the fact that this surface of the present, that is expanding at the speed of light, is the surface of a 4D hypersphere, in effect, a 3D volume. Does this imply a volume of 'now' that is essentially fixed ? A universal 'now' would cause issues.

My memory only goes as far back as points with vacuum/centrifugal advance in the distributor, and changing spark plugs every so often. To this day, you can still seriously burn your fingers when 'handling' hi-intensity Halogen bulbs in car headlights. ( you should also avoid 'handling' as the oils on your fingers contribute to early bulb failure ) Thank goodness for hi-power LED bulbs, distributed coils, and electronic fuel injection/engine management systems. ( although I would love an old MGB, TR4/6, Alfa Romeo Spyder, or, of course, a Jaguar XKE even with the fiddly v-12 engine )

So which one wins out for someone who is afraid of sex ? 😁

I can't believe you put 'logic' and 'Trump' in the same thought. Are you trying to process the 'reasoning' of a senile, stupid, and arguably crazy person ?

And certainly no 'Brothers in Arms'.

The Italian navy contracted Boeing and a couple of Italian naval defense companies, in the mid 70s, for a missile armed, hydrofoil, fast patrol boat. Only a few of the Sparviero ( sparrow-hawk ) class were produced for the Navy ( and some under license in Japan ), but its larger brother, the Pegasus class, intended for NATO standardization, failed to go on. https://en.wikipedia.org/wiki/Sparviero-class_patrol_boat

The fact that all known forces 'seem' to converge to equal strength at Planck scale, implies that all forces may unify at Planck energies. IOW, unification of gravity with color-electro-weak at approx. 1.2 x !0^28 eV. ( way beyond our reach )

Take some much needed advice ... People who have no cognitive filter, such as yourself, should stay off YouTube.

Maybe the involved states cannot be 'winners', but you can certainly have groups within those states that are. Halliburton comes to mind during G W Bush's Iraq war. And since America's former allies in Europe stopped buying American military equipment after he threatened invading ( buying ? ) some of them, the American military-industrial complex needed a handout from the taxpayers in the form of massive orders once D Trump depletes supplies with his war of 'choice'. Raytheon, Lockheed-Martin, Boeing and General Dynamics are cutting donation cheques to their favorite political party as we speak.

Except for the fact that this is not Poker or Go. It is not a game; it is serious, and it is putting the lives and livelihood of many people around the world in danger. Many countries like to 'war-game' strategies for actual war planning. I fear this trivializes the seriousness of actual war. War needs to be taken seriously, and have actual consequences, in order motivate its avoidance.

Today I learned that CERN has an 'anti-matter factory' and they have actually shipped anti-matter for experiments, to other facilities by truck.

You can't expect a war to go good if it is based on a faulty premise and idiotic planning. I would expect senior Pentagon officials and Generals to push back against stupid orders and war crimes; they are, after all, professionals, and the only 'grown ups' in the room. P 'ass-licker' Hegseth obviously didn't like sensible opinions, and fired them. ( I'm sure many more firings will come, including Hegseth himself; somebody has to fall on his sword for D Trump )

The right doesn't have a 'superpower', any more than if I said I could walk on water, and stupid people believed me. Their ability to 'spin' is based solely on their supporters' ability to suspend belief in reality. More like contageus mass insanity.

Let's not make the religious regime of the Ayatollahs look like angels by vilifying the Shah and the Americans. How many people did they kill a couple of months ago ? The Ayatollahs just used a different 'institution' to control the people, but the methods are the same. Meanwhile. D Trump is serving up TACO salad again tonight. And looking like a moron ... again.

Well, I wouldn't call York 'quaint'; it is larger than the city I live in. Although it does have many historical attractions ( for myself, at least ). As opposed to Poznan ( also with its many historical attractions ) Maybe you should get out to visit some of the smaller towns of a few thousand people, where everyone knows everyone else. That's where you find a real sense of 'community'; and every country has them. Big city life often forces a certain amount of detachment between inhabitants. In some BIG cities, people live, work, shop, and get their entertainment in their hi-rise building. Downtown Toronto ( one hour away ) is one such city; I don't like that kind of life, so I don't live there. Incidentally, I was born in a little town in South-central Italy, of 4000 inhabitants Sant'Angelo dei Lombardi - Wikipedia which I would definitely call 'quaint'. Oh, and today I learned where you were born, and you learned where I was born.

A visit to Poland is on my bucket list. You may be a bit too critical of the UK; it has its fair share of 'quaint'.

You're going to have to explain how you would accomplish that. As far as I know, a known method to achieve high speed underwater, is to envelop a torpedo in a sheath of air; the opposite og cavitation. Russians have experimented with such methods, using H2O2 to generate the sheath. The Kursk ( Russian nuclear sub ) incident of 2000 in the Barents Sea, is attributed to high strength Peroxide leaking from a faulty weld, into the torpedo tube, catalyzing a fatal explosion.

Bedford was the research site of the RAE ( Royal Aeronautical Establishment ) until 1994, and was the British equivalent of DARPA, with a supersonic wind tunnel. It oversaw prototype work and assessed whether manufacturer's proposals met Operational Requirement. Surrey was the home of Vickers-Armstrong and Hawker Aircraft, which later became Hawker Siddeley, at nearby Kingston upon Thames, under the guidance of the late Sir Sidney Camm, for 40 years. Vickers-Armstrong, and others, became part of BAC prior to the TSR-2 debacle, and later Hawker Siddeley was also folded into present day BAE. Incidentally, Westland, the helicopter manufacturer ( that used to do aircraft ) at Yeovil ( Somerset ), is now a fully owned subsidiary of Leonardo, an Italian company. Don't you Brits have any pride in your aeronautical history, and past accomplishments ?

I stay away from American swill also. Give me a crisp, cold Heineken ( Peroni, Stella, Konigsberg, Tsing Tao, or any beer brewed in the German tradition ) any day. Although a cold Guinness draught in a can can be quite refreshing.

"Trump Says Intelligence Played No Role in His Decision" Nor for the people who voted for him.

When I hear names like Surrey and Bedford, Britain's post-war aviation history comes to mind. Not beer, or that warm slop you Englishmen call beer 😄 .

I was just thinking of cavitation, as in pumps or submarine screw propellers, which is capable of breaking impellers. And loud enough togive away the position of the submarine to sonar.

They were excluded because the belief that celestial bodies affected human life pre-dated science as we know it. IOW, those were the only planets visible with the naked eye, to the high priests of the ancients. IOW, Astrology is NOT a science; take it somewhere else.

That's interesting. Granular solids can be made to act like liquids. We regularly 'float' Sulphur prills, or flakes, on a cushion of N2 pressure, so it acts 'liquidy', and we can suck it under vacuum into a reactor for dithionation processes ( flakes need different N2 pressure than prills ) at my work. This effect is also seen in avalanches and land-slides. By the way, @studiot , there is no such thing as a true 'two by four'.

So gases ( like air ) can 'fracture' also, at the shock line between supersonic and subsonic flow. ( just glad to be discussing something other than made-up 'theories of everything', or drug induced 'consciousness' in QM ) True, but they also adapt to reflector 'astigmatism' induced by differing mirror orientations. ( astigmatism is different curvature along different radial axis; I have plenty on my corneas due to scar tissue from many operations )
