  1. Re your (1) no, any ToE will remain subject to the possibility of refinement, modification or rejection, in case there may one day be new observational evidence that does not fit with it. Science aways stays open-ended, as we can never know there are no more novel observations to be made. Re your (2), never ending exploration has always been a given in science: it is intrinsic to what science is.
  2. You've already got one thread on this subject AND you've been told not to just attach files with no explanation. Reported.
  3. Ah, so the meringues I make are hardened against an EMP, then. Good to know.
  4. White objects do not absorb , or not much, in the visible region of the spectrum. But UV, as the name implies, lies outside that region. So visible colour is no guide. White clothing absorbs less visible light, which indeed makes it heated less by sunlight.
  5. You can never make such an assumption, so this scenario can never arise. This is because It is never possible to prove a scientific theory true. So we can never state with certainty that there is no more to discover.
  6. Well, you've had your answer from the people here. Your idea about making soil fertile by passing CO2 into it is misguided and won't work. Plants do not take in CO2 via their roots but via their leaves. As for "....the breakdown of raw elements into the dirt, with water and carbon (along with other chemicals) being pupmed under pressure into the churning mix", that does not describe anything coherent enough to comment on.
  7. Passing CO2 over poor soil won’t improve its fertility, but increasing the CO2 content of air in a greenhouse does accelerate growth. This has been widely done for years in the Netherlands, where a gas engine is used to generate electricity to light them in winter months, exhaust is used to promote growth and waste heat to warm them. This is done commercially to produce tomatoes, capsicums etc all year round for supermarkets.
  8. I still have those massive iron fireplace surrounds in the upstairs bedrooms in my late Victorian (1897) house. I was surprised to find, when planning some redecoration, that the mantelpieces are all magnetic.
  9. Why should we do that when it obviously won't work?
  10. Ah. Magnets. And harvesting energy. Does Tesla come into it at any point? Just asking.
  11. Are you seriously arguing that because the average air temperatures are different, there can't be any effect of air temperature on soil formation? Why consider the average? Why not the annual range, for instance? Or the difference between day and night? Aren't these more likely to affect soil formation and structure, via expansion and contraction, effects on moisture content, freeze/thaw cycles and so forth?
  12. Evolution and continental drift, I imagine.
  13. Ask a rabbit breeder.
  14. Yes, it's all a bit Dr Strangelove: "I'm not saying we wouldn't get our hair mussed. But I do say no more than 10-20 million killed, tops." (Buck Turgidson.)
  15. As you can't be bothered to explain what the hell you are trying to do, or even to converse in complete sentences, I've now had enough of you.
  16. Depends what you are trying to do. If you just want to show what is bonded to what then it doesn’t matter, but if you want show spatial relationships then bond angles can become important.
  17. Look, we are very willing to help, but you have to show you are making some effort for yourself, first. We want to help you learn, not to do the work for you so that you learn nothing. What you have written isn't even a sentence.
  18. OK but can you provide some insight into what is it that makes the correction significant for atoms with a high nuclear charge? Because that seems to be the point the undergrad explanation tries to address.
  19. No doubt that would be the more rigorous way to treat it, the concept of speed being a bit dodgy in such a context. But it was used to explain at undergrad level why these corrections are only required for atoms with vey high nuclear charge. How does this arise in the more rigorous treatments you have in mind?
  20. The undergraduate explanation for the colour of gold is based on electrons in atoms with very high nuclear charge moving at such speeds and thus, in terms of non-relativistic QM, having a greater effective mass than they would otherwise: https://math.ucr.edu/home/baez/physics/Relativity/SR/gold_color.html
  21. You mean "divine". "Devine" is a person's name. Your post reads like a rather incompetent attempt at a marketing scam: incompetent because there is no link to whatever business is hoping to profit from selling the stuff, and a scam because it claims bogus special virtue in water from particular places. (The claim about the Jordan is entirely false). At least as far as the references to Catholic locations are concerned, holy water in the Catholic church is simply water that has been ritually blessed by any priest, for use in various rituals in which water plays a symbolic role. It can be ordinary tap water, salt usually being added to suppress algal and bacterial growth. It is used in baptisms, in holy water stoups at the entrance to churches, in the "Asperges" at the start of traditional High Mass and so on. There is no need or expectation that it come from anywhere special.

    Ah yes, silly me, of course. I'd never come across this abbreviation, curiously.

    "pbuh"?
