If it were permanent we’d probably notice the correlation.

The ether was discarded, as it did not match with evidence. Are you sure you want to describe your conjecture in that way? That wasn’t the objection. ! Moderator Note the objections are not personal and they are related to what you wrote; the interpretation of animus assumes too much. What you write is insufficiently supported with valid science. You may have been expecting a credulous audience but you don’t have one. Leave the animus out of the discussion and focus on clarifying and supporting your claims.

I commented specifically on the phrase “pure velocity” which is nonsense. You had an opportunity to explain what you meant. I notice you did not take it. Having a compton radius doesn’t mean they are the same. They both have charge and mass. There are significant differences between them. Please provide support for your claims

We can know what the military anticipated though. They made >1.5 million purple heart medals in WWII, many in anticipation of the invasion of Japan. Almost 500k were left over at war’s end. They’re still issuing medals from that stock.

Pure velocity? Pure nonsense. What do you think that shows?

! Moderator Note We often call this numerology. It's not science and this discussion has no place in a science forum.

A) Hot water? B) If one has to read between the lines, you can't argue about good faith. You've admitted that the meaning isn't clear. Since you quoted both Tokyo and the A-bomb, no that's not at all clear. But my point still stands - the circumstances were very different. The burning of Washington was not the culmination of some systematic retaking of territory as the opposing force was drawing closer and closer. If Washington had been burned after the British had won dozens of battles and were occupying a bunch of territory that the US had previously held, then we could compare the situations.

The circumstances surrounding this and Hiroshima are hardly comparable.

Klaus Fuchs. The Rosenbergs. And others. Also, your premise that Japan was beaten does not match the facts. They did not acknowledge it. They rejected the Potsdam terms. They did not surrender, even after the first bomb was dropped. Did they do their own Manhattan project equivalent, or did they use pilfered results? One thing about research is the time, money and effort you spend finding out things that don’t work. Subsequent efforts don’t have to expend resources chasing these down.

Yes. I don’t think your post has a sold basis in fact.

Assuming it would be economically feasible to retrieve these metals, I think the question this raises is what would happen if you could suddenly e.g. double the availability of these rare metals. IOW, are there efforts that are supply-constrained? If the new availability drove prices down, it’s possible that you’d come up with new products that aren’t currently viable owing to cost.

The blocked light forms a cone (see the eclipse link for an example) s = r*theta s is the size of the block. theta is the angular size. r is the distance to the screen blocking the light.

There are situations where this isn’t true, though it’s not truly thermal equilibrium - you can cool a sample of a dilute gas with lasers, with the axes being independent. One- and two-dimensional cooling can take place. The atoms equilibrate with the laser light. The photons don’t interact with each other, so the velocity profile in each dimension can be different. The atoms are dilute and move very slowly so they scatter much less often with each other than with the photons.

In thermal equilibrium you can’t decouple these effects. You can’t create a situation where you have the translational motion without the non-translational motion.

Yes.

Have you ever noticed that e.g. a tree or house some distance away can block your view of things further away?

If you want to block the whole star from all of earth, you need something the size of the earth. If you just want to block one person from seeing it, you need something roughly the size of someone’s face, though diffraction will mess with this. Arago’s spot means light will still be there. https://en.m.wikipedia.org/wiki/Arago_spot

The size of the “light beam” is approximately the size of the source; even bigger, since over 4 LY you can’t ignore the divergence. Alpha Proxima is bigger than a few mm. The beam illuminates the whole earth, i.e. you could observe the star from any point on the surface unless earth itself is in the way. Diffraction means you need something bigger. Diffraction, and that the sun is bigger than the moon, and that the moon is some distance away. The light is not parallel. If you were closer to the moon, the dark spot would be bigger.

This makes no sense. An angle, by definition, assumes a vertex, which is a point. The light from Proxima Centauri hitting the earth can be treated as parallel over such a short distance as the diameter of the earth. The angular size of the star is not the same as the divergence of light from it.

There are 7-day programmable timers. You’d only have to reset it once a week. Or do e.g. a 42 hour cycle I think there are 14-day timers, too

The magic number is 18. That’s how many years it’s been since someone had last posted.
