Electric Solar System Theory

[Gord_in_Toronto]

I allot hesitate to post this at all and certainly in none of the current Electric threads but:

Scientists work out why the inner solar system seemed to break the laws of physics

This motion makes the disk becoming akin to a giant battery – with a positive terminal near the centre and a negative terminal at the edge. This creates huge electric flow and powers astrophysical jets that shoot out in both directions; these have been observed by astronomers for over a century, without them ever knowing the force behind their origin.

From the comments (I did not feel like registring to read this article):

The original paper discusses the angular momentum of charged particles in protoplanetary accretion disks, with emphasis on the inner regions of such disks, but doesn't mention planet-sized objects.

which would make sense, as the planets just obey Kepler's laws (well Mercury needs a bit of Einstein's).
The first paragraph of the article is misleading

Scientists believe they have solved the mystery of why the inner solar system spins much more slowly than the laws of physics suggest it should.

because right now there is no mystery. The second paragraph

The inner ring of the solar system contains thin layers of gas and dust known as accretion disks, which spiral around young stars heading slowly inwards.

talks about a "ring", which there is not in the inner solar system. They forget to say that this is about the early solar system when there was a protoplanetary disk, which like an accretion disk can have plasma dynamics, with the creation of magnetic field etc.

(interestingly, now the whole article is there now)

Paul Bellan did some simulations about the disk and here is the paper in ApJ

The link in the OP is to Bellan's paper. The same one you reference.

I agree that his work does not apply to our solar system at this time. It is about an earlier stage of planetary development, before planets have formed and when there is an accretion disk. The headline is hugely misleading.

Seem that, in context, the laws of physics remain perfectly intact in this case.

Am I missing something?

Inner Solar System spins mysteriously slow; breaks laws of physics!

Help!

I guess it is all a case of a badly written press release and then misunderstanding by the science journalists.

I'm trying to remember everything I've ever read about Kepler's Laws and the precession of Mercury to come up with something that says there is a problem.

Oh. Oh.

According to the chart here: Tests of general relativity^WP there is still a small difference in the observed precession of Mercury and what is explained by everything otherwise known.

Does the current research explain the difference?

 

[tusenfem]

Does the current research explain the difference?

No, because the current research deals with the protoplanetary nebula and not with actual planets.

This is a dusty PLASMA. Ask tusenfem about dusty plasma's.

He knows a bit.

Ah. Never mind. It's my fault for misreading the headline. I read "seemed" for "seems".
