If each Galaxy has it's own Polariztion then they would seperate faster and faster without dark matter...just a thought.

EDIT: I don't know if Galaxies put out giant magnetic fields like I have seen images of Earths. If they do they must extend a long long ways. Over time many galaxies would have "Bounced" off other galaxies fields and some would move faster some one way some another. Seems it would explain a whole lot a Woman on "Through the Wormhole" was trying to explain about dark energy....

I actually don't know what you mean when you ask Are Galaxies Polarized?

So my answer would be no.

And what you suggested about galaxy's bouncing off each other is way off the mark. Astronomers have thousands of images of Galaxy's actually crashing into each other. But instead of a crash, its more like they gently merge with each other to form one single larger galaxy. Galaxy's never repel each other!

Today's science would suggest that both galaxy's sit in a gravitational well and that's why they attract each other. Personally i would disagree with modern science, but that's just my personal opinion.

I wonder if hiamps meant a galaxy magnetically polarized as a whole body?
Since galaxies seem to form a spiraling circle this would suggest that magnetic polarization probably does not exist. But the foregoing is only a quick assumption on my part here. I'm trying to imaging what would occur if you magnetized a whole load of of ball bearings. Then once magnitized you placed them on a glass surface, how would they form up, what shape would the whole mass take on?

I'd say no galaxies are not polarized. If that were true our solar system would be spinning along the galactic plane. from what I've read and seen it does not. Our sun spins at an angle to the galactic plane. This could just mean that we are not original members of the Milky way galaxy and were absorbed as part of a smaller galaxy billions of years ago. Or there really isn't any actual order inside a galaxy

The galaxy's circling shaped spiral would suggest some element of order at least.

true there is a direction to the spin however you'll notice that there are left and right spin galaxies.

I think that depends on the observer more than an actual attribute of the galaxy. See from one side, a galaxy would have a right-hand spin but zip over to the other side and it would have a left-handed spin.

Which way is north?

Actually I wonder if a study of galaxy spin direction might tell us something about the plasma and the vortexes in it near the plank time. Perhaps not because of galaxy collisions.

The first and obvious question is: What do you mean by galaxy polarisation? It's not at all obvious.

Do you mean its emissions? What kinds then? If any - from far infra-red to gamma rays then the answer is clearly no. Polarised matter? What's that? Anything else?

You need to define what it is you are asking about.

I've read of a recent survey of galaxies rotating clockwise or counterclockwise. If I remember well counterclockwise are more frequent.

Yes, there's this recent report:

Was the universe born spinning?

The universe was born spinning and continues to do so around a preferred axis – that is the bold conclusion of physicists in the US who have studied the rotation of more than 15,000 galaxies. ...


Well, there's some deep thought needed to untangle that one! There's also a high level of uncertainty with the restriction of viewing only from the single perspective we have from the Earth.


Not sure what is meant by "polarisation" for this thread. However, there could well be significant effects from galaxies harbouring a net electrical charge and from magnetic lines of force. There may even be galactic winds pushing along just as there is a solar wind for our solar system...

Also, could the pattern of dust clouds unbalance the net pressure from the radiation from a galaxy to distort the picture?

And then there is gravity.


It's all a question of how detailed you might want to go!

Keep searchin',

Born spinning or born tumbling? Spinning being more orderly than tumbling which is more erratic in rotations. The formation of galaxies came after the big-bang and after the first formation of matter. I'd say that the universe was formed tumbling that then lead to the formation of galaxies that are spinning.

isn't spinning just organized tumbling

If the universe is shown to be expanding at equal rates along all planes then I suppose you could assume a more orderly pattern to events leading up to the creation of matter. If expansion can be shown not to be equally spaced out along all planes then you could assume a less orderly creation of our universe. Where, in the latter case, energy was more selectively bunched when forming matter hence interference could co-exist between this forming matter creating a tumbling effect rather than just a spiraling effect. Did matter occur at the center of the big-bang or was it created some distance away from it. If matter was created at some distance away from the bang then I would consider the creation to be more orderly in fashion. I.E. at a set point away from the bang matter was then being able to be formed hence less likely to interfere with other matter since there could only be matter forming aside of it, nothing forming behind it and ahead of it matter flying away already formed.

Perhaps the spiraling we see in our galaxies came about due to the energy, built up inside the big-bang, actually spiraling itself prior to release. Hence causing all matter to tend to spiral so giving us instant gravity on creation.

Hey Skildude any chance of a Nobel Prize here....just having a laugh

the universe at one time billions of years ago may have expanded equally in all directions. the interaction of Galaxies with one another seems to quash that theory. If super clusters attract other matter it would make sense that the expansion in those areas is slowed a bit
