This is a fairly arid speculation since no one claims physics is complete and there are reasons to think the laws as we understand them may not have been applicable in the first instants of existence of the cosmos. As to something coming from nothing, that is exactly what these virtual particles you have been complaining about represent, due to operation of the uncertainty principle. Things have moved on a bit since the time of Parmenides, as this Wiki article points out: https://en.m.wikipedia.org/wiki/Nothing_comes_from_nothing

Fair enough. Do you have any idea what this vast non-combustion source of CO2 could be in Canada? (If you go to the link and click on each country, you get a bar graph and pie chart breaking down the contributions.)

Actually, some of us do wonder why you are here. You seem armed with all sorts of information, yet contrive somehow to talk almost exclusively out of your arse. I suppose it must the goddess Kali’s doing.

Aha, that’s it! Then I was being unfair to the poster who I thought was talking gibberish. (It was the drives lasting longer than 10 seconds that really threw me.) I must admit I am not sure how useful electrochemical réduction of CO2 to carbon really is, considering the energy input required.

Oh no, not this rubbish again. (My grandmother ate Energen rolls as part of her calorie-controlled diet.)

You are by your own admission no scientist, yet, quick as a flash, you present one cherry-picked study, out of thousands, that has not been peer-reviewed. How very mysterious. Goddess Kali again, perhaps?😆 But seriously, in this thread you were shown a peer-reviewed study, reported in Nature, showing that infection with Omicron following vaccination confers broad protection against a wide range of variants, while simple infection by Omicron of unvaccinated individuals did not. Here’s the link again: https://www.nature.com/articles/s41586-022-04865-0 What hysterical balls.

That Worldometer site only looks at CO2, not all greenhouse emissions. So meat-eating etc is not factored in. It does not seem clear how they calculate the numbers, so I can’t see whether emissions related to fossil fuel extraction are included or not, but I suspect they will be. Assigning “blame” is not what per capita figures are about, though, surely. What they do is focus minds on economies and societal lifestyles, as people try to work out why one number is higher than another. What sticks out in the case of Canada is the huge amount of “non-combustion” emission, over 20% of the total. I don’t know what this is, but it cries out for an explanation.

But far less in the vaccinated, as levels of virus in an infected person who has been vaccinated are much lower (that’s why they don’t get so ill, you see) and the duration of infection is far shorter. So vaccination greatly reduces the opportunities for the virus to mutate.

No, work is a form of energy. A force, acting through a distance, F x d, = W. Mechanical work is one form of energy. For example if you lift a mass you exert a force to overcome gravity and do work on the object, thereby increasing its gravitational potential energy. To say energy “directs” work makes no sense.

I seem to remember it can be more complicated than that in transition metal compounds, due to the presence of multiple valence electrons and the effect of the ligands on the relative stability of various d orbitals: cf. crystal (or ligand) field theory. But I have no idea how the crystal structure of minerals might be affected in a meteorite impact event.

Oh, I’m so sorry, I hadn’t realised you are a nutcase. I’ll bow out, then.

I repeat: try engaging with the responses you have received, rather than starting again from the beginning each time.

I suggest that, rather than merely repeating your original assertion, you try to engage with some of the responses you have received. Unless you do that, no progress in understanding will be possible.

Don’t delude yourself. There is no evidence the Big Bang hypothesis is under serious threat and, if it were, it most certainly would not be anything to do with your thread here. Cosmologists get ideas from each other, not from places like this, and your ideas are not particularly insightful. But the side discussion it has prompted about web crawlers and reasons for numbers of “views” is actually quite interesting.

But you also have +ve and -ve electric charges, resulting in both attraction and repulsion, depending on the combination. Yet we deal with those in terms of a single electrostatic interaction. Do you think there are different forces in that case, too, then?

You are not thinking clearly. As a result, you are confusing force, which certainly has a direction, with energy, which does not. You have a force between 2 charged particles, which diminishes with increasing separation. An increase in energy is the work done by moving them a certain distance against that force. That energy has no direction.

All this from someone who by his own admission doesn’t understand the science, and is only asking questions? Eventually , perhaps, needing to modify the vaccine does not constitute “disaster”, you halfwit. It’s what we do every year for ‘flu’ vaccines, so completely standard practice.

By the way, this poster, under the name jb71, seems to be spamming identical crap on other science forums: http://www.thescienceforum.com/health-medicine/51094-geert-vanden-bossches-covid-predictions.html#post635485 which tends to support the suspicion that the poster is not acting in good faith.

Yes, I must say I am becoming rather suspicious of the motives of our poster. The bit about Omicron and breakthrough infection is particularly interesting - and encouraging. It starts to look as if the future may be one in which repeated infections, rendered mild by vaccination, may enable the population to tolerate endemic Covid without significant severe illness. Though I suppose that one day an evolutionary jump to a nastier version is always possible. At which point a new vaccine can be produced.

You are now recycling crap that has already been amply dealt with. VAIDS is a myth. ADHD meds only help people with ADHD, by reducing the ADHD symptoms that make them more liable to catch the virus.

Well if you are relying on Goddess Kali for information, why do you bother making ill-informed and disingenuous arguments on a science forum? Or are you just trying to generate more search engine hits for your favourite cranks, charlatans and misinformation specialists?

And you “know” these two - quite separate - things how?

This is totally garbled. First, non-neutralising antibodies also help against infection by marking the virus for destruction by phagocytes. So they are generally a good thing, not a bad thing. Secondly, partial escape of variants from previous immunity seems to mean that while people catch the virus in spite of being vaccinated, as I did recently, they don’t get very ill. Upon recovery, they are likely to have a broad-based immunity, deriving from having been infected. So there are some grounds for thinking that vaccination does a good job of blunting the impact of these newer variants, while building broader based immunity from people getting mildly infected. But you ignore all this in favour of promoting alarmist nonsense from cranks, using one argument after another, to suggest that vaccination is some kind of disaster, even after each one is shot down in turn, all the while professing innocence because you are not a scientist. The obvious question is why, if you are not a scientist, you are so determined to ignore what mainstream medical opinion is saying, focusing instead on fringe and crank opinion in preference. Why is that? Why is it so important to you, personally, that vaccination be shown to be a bad thing?

False. I also pointed out what the article actually said. Vanden Bossche has not published any research since 1995, and what he published before that was veterinary medicine. I have just amended my previous post to include an article in today’s Guardian about Omicron BA.4 and 5 and the continuing effectiveness of current vaccines at preventing serious disease. Suggest you read it and cut out the dishonest antivaxxer crap.
