    Why is the sun changing polarity every 11 years?

    and
    Does the sun’s magnetic field create the dip in the gamma-ray spectrum at 10 trillion trillion hertz?
    if so
    How?

    What?

    Reference please.
    A dip in which gamma ray spectrum? Dip compared to what?

    picture the @11 yr schwabe cycle as 1/2 of a sine wave

    1/2 above the neutral 1/2 below
    the sun's magnetic poles switch in a periodic manner @every 11 years

    and...............
    why? remains a mystery

    I don't think so. Reference please.

    sculptor:

    Thanks!

    I've learned something new today. I was aware of the 11 year cycle, with the variation in sunspot activity etc. However, previously I was under the impression that this was related to the magnetic field of the sun fluctuating in magnitude. Apparently, though, you are right: the magnetic field actually undergoes a complete reversal, or "flip". The reasons are a bit complicated...
    Really? Basic common knowledge, eh? Shame on me, then.

    I'd like to hear your simplified explanation of the above, in terms of the basic common knowledge you have, because the above explanation seems quite dense to me - and that's just the wikipedia condensed version!

    It's always a good idea to confirm things with reference to expert, reliable sources.

    I wouldn't trust you as a sole authority on anything to do with the science of global warming, for instance, because we have already established that your understanding of that topic is woeful.

    Indeed. I was as shocked - and mortified - as you to find this out after almost six decades.

    It's a lot like "Oh. There's a group of mammals that are rodents? News to me!"

    Not everything, no.

    But ye gods, it's like discovering rodents after six decades of biology enthusiasms.

    and
    that is just the beginning

    My great uncle Charlie couldn't remember how to get home.
    He knew how to get to the home where he grew up
    but not to the home where he had farmed for over 50 years
    poor old Charlie---big strong hands and really old memories
    that were as fresh as though they had happened yesterday

    Old memories have had more time in the brain to create stronger links between neurons

    It is a bit surprising to me that we have not been able to understand why the magnetic field is changing, considering it has been known for 60 years that the polarity switching goes in a 22 year cycle.

    When it comes to that, we aren't even sure what causes the Earth's magnetic field to shift around and flip over every now and then. And the Earth's a lot closer to us than the Sun.

    That's okay, son. Run along now. And play nicely with your little friends!

    To truly understand why it flips, you'd have to know the exact mechanism which creates the magnetic field in the first place, and the exact conditions in the interior of the Sun. This is not something we can go out and directly measure, and while we can garner some information about these things, it isn't enough to point us in a definite direction.

    It just seems like the short cycles and the regularity of the flips would provide opportunity to reveal some mechanism. Clearly, not however.

    it's a time thing
    1st notice the phenomenon
    develop the instrumentation
    get it funded and scheduled
    see what you can see
    refine the instrumentation
    get it funded and scheduled
    see what you can see
    refine....................................................
