Hi again Haig.
I know you were responding to Lukraak_Sisser ("LS"), but as I pretty much agreed with everything LS wrote, I hope you don't mind if I also respond to your post.
Well LS you are aware (aren't you) that the lander Philae (and Rosetta) have Faraday Cages built into protect their instrumentation?
Well, from the material you posted earlier, on the electric comet, there should have been a quite dramatic electric discharge, between the comet's surface and the metal tips and sharp edges of several parts of both spacecraft.
Of course, none of the electric comet material you posted contains any quantitative calculation, so all we have to discuss is bald words, which are quite inadequate to get to the bottom of this, right?
An also, Rosetta and Philae approached 67P so slowly thus minimising the charge difference between them.
I'm really puzzled by this, Haig; I hope you can sort my puzzlement out for me.
According to 'electric comet', a comet's jets are electrical discharges, caused by the huge difference(s) in electric potential between the comet's surface and the solar wind/field. And these jets stretch across quite enormous distances.
Yet Rosetta started out at a quite different 'solar potential' than where it is now, but has no jets streaming from it. If the slow approach of Rosetta minimized the charge difference between it and the comet, and the comet is still at such a huge difference to the solar wind (etc), how come Rosetta doesn't have jets too?
If a spacecraft and lander approach a comet fast then you can get a huge reaction like this Deep Impact: Confirming the Electric Comet
I may be wrong, but I think member Reality Check has pretty thoroughly debunked that. While he may have gone a bit too far in calling what's posted "lies", I can't see any way round the conclusion that the authors of that material have badly misrepresented the facts.
You seem to be missing the point LS try reading it again.
While I'm not LS, I did read it again, and still cannot see where/how LS misunderstood anything.
Perhaps you'd be kind enough to go through it, in detail, showing exactly where both of us have (so badly, apparently) misunderstood?
'Electric Comet' Could Burn The House Of Science
"The standard theory, it seems, has been kept alive by the discovery of water in comet comas and tails, not on the nucleus itself. But what is the source of the water in comet tails? Ironically, electrical activity within cometary comas may have deceived investigators into thinking that their model is intact"
I know tusenfem has asked - many times - for details about this, but so far (as far as I can tell) you have not provided any answers.
So let me try asking too: where are the calculations of the expected amount of water, from comets, using the electric comet idea? Where have analyses been published, showing that these expected rates are consistent with the published observations?
Well it seems you can take LS to water but you can't ... Maybe a re-read might make things clearer for you?
Again, I'm not LS, but when I re-read the material (and re-re-read it), I was left with the same, unanswered, questions as LS.
Perhaps if you could post links to published material containing actual models, with calculations, numbers, etc? That would certainly go a long way to addressing the apparent misunderstanding.
There are LS!
All the planets are charged bodies with plasma sheaths surrounding them (Earth's is called the Magnetosphere) and the Sun is a charged body has it's plasma sheath too (mainstream call it the Heliosphere}.
Actually, you didn't answer LS' question, sorry.
However, your response opens up the chance to ask this question: what are the charges on the planets in the solar system? on the Sun? On the comet Rosetta is currently orbiting?
I would assume that, since you know all about plasma sheaths etc, you could simply apply the well-known laws of electricity and work out at least the relative charges on all these bodies? Or at least provide good order-of-magnitude estimates of them?
And if you personally can't do such calculations, surely 'the electrical theorists' have done so, right? Please post links to where such calculations are published.
Can you imagine the size of the Universe LS? Well 99.9% of that is Plasma and plasma can carry electric currents that generate magnetic fields, called Birkland Currents. The current is generated continually by the potential difference across the Universe. That's what lights up the Universe and why we can see huge chains of galaxies. There are local variations such as we find in our Sun with it's various cycles. (btw now heading into a Grand Solar Minimum) This is my understanding from all this you and the rest are free to make up your own mind or simply follow.
I'm really quite lost here Haig, so I hope you can help.
If the Sun is enclosed in a plasma sheath - as you said earlier - then as long as comets, planets, spacecraft, etc do not go outside it, what happens in the rest of the universe is irrelevant to the point LS is making, right? All that matters is the relative charges on all the various bodies within that plasma sheath, right?
If they are close enough there are reactions! Never heard of Sun diving comets? There are lots of examples of this ...
Really?
This would seem - at first glance - to be something 'electrical theorists' would have researched extensively!
Do you know where their research results have been published? Quantitative ones, I mean, which consider all CMEs and all sun-diving comets, address selection effects, do quantitative analyses of the observed 'reactions', etc, etc, etc.
How is the tail of a comet pointing away from the Sun make Electric Comets theory wrong? It's actually the opposite it makes it right! Ask yourself if comet tails are just sublimating ices and dust WHY do they stay ATTACHED to a very low gravity body like a comet? and sweep around the sun like a blade at perihelion? That's an electromagnetic effect LS
I'm with LS on this too, Haig.
If comet tails are some sort of discharge, why do they all face away from the Sun? And why are there two tails? At the very least I'd expect comet tails to point one way when they're 'incoming' and the opposite way when they're 'outgoing' (but they don't).
Can you explain this for me please, slowly, carefully, and in detail. In your own words, not by posting yet another link.
