Voyagers and the EU
Is this aligned with the EU model about the heliopause ?

I remember that Thornhill talks a lot about how the conventional model of this transition zone is wrong and the EU explanations do fit the data...

Is there a typo in the third to last paragraph of the article where it says,ttsoares wrote:Is this aligned with the EU model about the heliopause ?

??The MAG shows that the magnetic field strength decreases sharply in the interstellar medium.
The graph provided indicates differently, as does this Physics Today article from Feb 15, 2019. Or are they just ignoring the the year or two crossing (presumably) the heliopause ?

Apparently the question of Interstellar Magnetic Field direction is once again all over the place too.
Some of those earlier IBEX and other solar system related EU Forum threads may need to be revisited, as learned and published white papers are being shredded and disavowed all over the galaxy as well.

Re: Voyager MAG readings
Yes, the whole IBEX interpretation was wrong from the start. They had so many assumptions, right or wrong, it was hard to know where to begin. First, they say those neutral particles started as ions, that picked up electrons at a key point in their spiraling along the background magnetic field,and were flung into the inner solar system. It’s that idea that allowed them to “determine” the background magnetic field direction.seasmith wrote: Apparently the question of Interstellar Magnetic Field direction is once again all over the place too.

.
That assumes that those neutrals started as ions (where is the evidence of recombination?). Also, assumes that there was no electric field to accelerate those ions. Also, assumes the ions were already streaming from a fixed direction (ions spiraling along a magnetic field would have to have a fixed direction AND energy, for the recombined neutrals to leave on that same tight path.). Etc.
If all their assumptions are correct, then they were measuring the magnetic field direction. If even one assumption is wrong, then then the magnetic field direction derived from the IBEX model is wrong.

Re: Voyager MAG readings
I always appreciate the common sense and practical approach aspect to your comments. You usually teach me something too and explain it simply. You tend to zero in on the core assumptions pretty succinctly.celeste wrote:Yes, the whole IBEX interpretation was wrong from the start.

It is a bit misguided to focus exclusively on the neutral particles hitting a random satellite when you're living in an electric universe. It would be pretty easy to miss all the important particle flow patterns going on.

Re: Voyages and the EU
I have seen, but cannot now find, an illustration of the heliospheric current sheet(Parker Spiral) that gets very vertically wavy out near the heliosphere boundry.
Would not that shape, if correct, cause confusion about the magnetic field orientation out near the Heliopause ?

Perhaps someone has seen this illustration and can post it ?

Thanks, No.
That is relatively close to The sun.
The one I have seen is that one, but extended, to show the curves becoming taller and much closer together
in the outer solar system.

The heliosheath is now known to be a sphere and not a teardrop, based on IBEX data.

Re: Voyagers and the EU
Today I read it was announced that V2 has reached Interstellar Space. What I found most interesting the juxtaposition of words. It was said to go from the 'hot low-density' of the Heliopause, to the 'cold high-density' interstellar region.
Doesn't that seem strange? I mean when we look at plasma density, or electron density, around the solar surface, or even better Saturn, you would never see hot with low, and cold with high?
So if we remove the temperature pseudo speak, and just think of density, this gives a picture of quite a different thing. That the interstellar medium is highly, massively on scale/volume, much higher electric density, then the heliosphere, our Solar System. The Atmosphere of the Sun, protecting the whole System from the very powerful interstellar plasma, just like the Earth from the Sun and it's Solar "Wind".
Long Live the Voyagers!

Re: Voyagers and the EU
If you look at solar wind plasma, that's exactly what you see: hot and rarefied fast solar wind and colder and denser slow solar wind.Cargo wrote:when we look at plasma density, or electron density, around the solar surface, or even better Saturn, you would never see hot with low, and cold with high?

I don't mean the wind, but the bodies themselves. Perhaps I should fetch some references.

Re: Voyagers and the EU
Okay, so briefly, what I was seeing too much of was the same curve graph that looks like every other plot from every other plasma boundary. They all don't conform to a common axis configuration. Whether it's Earth, sunspots, Saturn, etc.. And then when I remember the way plasma scales, the temperature words I just threw out. And of course, I didn't realize just how hot the LISM is. Fascinating.

"Scientists speculate that one day we may be able to create something called the Alcubierre Warp Drive, which sounds like something from Star Trek, but has a basis in reality. The warp drive would not so much propel a spacecraft as it would manipulate space itself, compressing it ahead of the spacecraft and stretching it behind, riding a “warp bubble” to achieve faster than light speeds."
