When they fly along with a plane (as in the Kaikoura Incident) it is tempting to think of intelligence (remote controlled) at least if not aliens.

So are you disregarding all the UFO sightings, even mine mentioned in the OP? When one considers the UFO sightings and how they seem to "know " what humans are up to, I have this notion that they must have discovered how to communicate and travel at much faster rates than we are restricted to. So how are we going to pick up their transmissions when, by implication, they must be operating with vastly different methods.

In the Kaikoura Incident the entity was detected by radar. https://en.wikipedia.org/wiki/Kaikoura_lights I remember these events well.

So how does this relate to the OP? Would you agree a signal is unlikely to be picked up from an ET like slime mould? The more natural armour a life form has the less it will need brain power. Would therefore any ET intelligence come from a frail defenceless looking entity? One with a head (brain) out of proportion to the size of its body.

How do you know that?

It seems that this formation was seen by others and it was photographed by a Carl Hart in 1951 but I wasn't born then. His photo and my recollection seem very similar, with the stars in the background. https://en.wikipedia.org/wiki/Lubbock_Lights http://saturdaynightuforia.com/html/articles/articleimages/itn52p1alubbock1.jpg But the year is still baffling me!

This is my simple understanding. Each atom in the material has a magnetic field. I understand it is the alignment of these molecular fields that ultimately produce a magnet. So a piece of iron starts off with the same number of atoms, and it becomes magnetized by some method. I think it depends on the degree of alignment at the atomic scale that will determine the strength of the magnet. So is it fair to say one can never cancel a field line but one can alter the combined nature of the field lines.

I'd agree with that logic. Only issue that I'd raise is that when you push two magnets together you can't tell if some of the field lines are being cancelled. Obviously most of them aren't for the like poles are still repelling.

I haven't got two bar magnets to test it, but wouldn't it be like an electromagnet made with dual windings each in opposite direction. It the current is applied to either circuit the solenoid would become magnetized (but with opposite polarity) so when the current is simultaneously applied to both circuits would one field cancel the other?

so does that mean the area is always constant irrespective of the radii values?

Yes you can push them together but what has that done to the combined strength of the overall combination? I predict that the combined magnet will have reduced strength at the non touching poles.

I was thinking if a bar magnet was machined down to the wedge shape, each piece of the original magnet removed would reduce the strength of the magnet. I can't see any reason why each wedge shaped segment couldn't be still magnetized but what happens when the segments are all fitted together? Logic seems to say that one side will cancel out the opposite side so I'm picking that the sphere will not be an effective magnet.

So each magnet is cone (wedge) shaped to begin with. I would think a wedge shaped magnet has lost some of its magnetic field in the process of producing that shape.

That is my point. If they do pick up a signal would it not be an indicator that the signal comes from somewhere closer?

True. That is something generally overlooked. Would that blueshift be counterbalanced by the motion of the receiver?

Have you considered the resolution of the image? You are traveling at speed 100s of millions of light years away near an object that also bends light. The light that is coming from objects on Earth that reflect only a little bit of scattered light. You might just be able to see the Sun but not much else.

I would prefer a visual search of the sky rather than one looking for signals. Can they set up digital cameras that can automatically determine what it is looking at and what needs human intellect to further determine what it is in the picture? All the variety of known things that cross the visual field will need automatic elimination. Is it possible for this to be done? Like the memory of what I saw in the OP, the "V" shaped formation that was high among the stars, what could determine if that was in space or just in the atmosphere? It had the stars of the Milky Way as a background and now I know how far away they are but I didn't know anything about that as a teenager or younger. Time lapse picks up objects moving faster than the Earth's rotation against the background of the stars, so if there were additional streaks across the sky they could be examined. Can digital cameras do time lapse images as did the older type cameras?

"Life will find a way", maybe but there have been extinctions where the "way" has become impossible to overcome for millions of species. Well do you accept that life has not been beaten if a single bacterium survives? I would say NASA will be happy to find a living species of bacteria on Mars. But really that is not the type of life we want to relate to. We want intelligent life forms. Do we want to learn from them? UFO and ET seem to be the ultimate find for if they are here they have already mastered the technology of interstellar travel.

So in heat transfer by conduction how do you think the energy is transferred from one molecule to another? Could it be virtual photons in that case?

ETs classically displayed on YT etc look even more in need of social cooperation. They always appear to be incapable of survival in a wilderness situation.

Wouldn't it be a transfer of a photon?

Good point. They might in a region with other ETIs closeby. In our case we feel alone and that is our desire to feel less alone. I suppose we too will go silent if we discover we are not alone.

What made you say that?

I read it as "almost any result" so that might imply not all results hence not truly random. I have my doubts that it will be anything other than truly random but I want to see the results of his experiment first.
