    no we are talking about something completely different
    nor am I. Your completely vague.

    Everything in atomic physics is completely "sailent" until you study them all

    Can you cite that Galaxy is not spinning..

    You re read what Paddoboy said. It will be in order to teach him that spin of BH does not repel. Tell him about the accretion process.

    The galaxy does not rotate as a single unit....
    Would you like a link?

    You seem to be getting rather desperate my friend...claiming all that I say when I do not say it. Some matter is "repelled" primarily due to interacting magnetic fields, rotation of the BH, that twists these field lines, and throwing some of the matter out at the polar regions in the familiar polar jets we see.

    This is not same as what you posted earlier. Good one, you are getting it.

    Again spin is most certainly a factor, as with the twisting magnetic field lines, matter is caught up and thrown out at the polar regions.
    Obviously you are not getting it, considering the amount of times most reputable members need to repeat themselves and correct your agenda driven misinterpretations and straight out bungles.

    Of course the most interesting fact about a BH's gravity, well actually tidal gravitational effects, is the fact that in time, gravity overcomes all other forces known in physics, including the strong nuclear force, which sees matter that is swallowed, spaghettified and torn asunder into its most basic fundamentals parts......

    I hope you have learnt by now (in last two days) that BH spin does not repel the matter. Period if you have learnt. You know that is one of my objective to educate you.

    Why do you think that you're qualified to educate anyone?

    When did you last post anything relevant to science on any of the forums? You may give the link.

    When did you last post anything that wasn't anti-mainstream trolling?
     
    paddoboy and Kristoffer like this.

    You say trolls don't let you post science here...my poor baby...so you post science somewhere else. Where is that lucky place ?

    And by the way...anti mainstream need not be anti- science.

    That is just taking cue from Janus, but it is just the mind incredulity. You guys are not able to visualize a scenario where otherwise a small peck called our Milky Way in the universe may be spinning. You are too bogged down with the MW parts and its size. But its nothing but a small blue spinning dot.

    This thread is about centripetal force versus gravity- and refers to galactic rotation. The fact that our galaxy is not a single object - but 500 million plus individual objects bound only by gravity - is crucial to Tim's understanding of why there is no centripetal force.

    What do you mean by single object ?

    See, any bound system can be considered as single, so in that sense our galaxy can be considered as a single object in certain context. It does not matter that bound system is due to gravity or due to electromagnetism. It is absurd to say that since few are not able to grasp the galaxy as integrated unit, so it cannot spin. Take for example our solar system, if it can have a translational motion around Galactic Centre as a single unit, then surely it can spin on some axis. Why do you think it is not a single unit? The analogy extends to the Galaxy on a larger scale. Are you aware of the angular momentum paradox of our solar system ? Are you aware that our Galaxy has a gaseous halo and that spins? and how ?

    You are the one who infers a BH, cannot move...you are the one who infers that matter is not sometimes repelled....you are the one who infers that BH's do not exist,

    you are the one that infers that you can teach anybody!

    And like that other scientific stalwart expletive deleted, absolutely nothing to support your pseudoscience take on anything.

    Obfuscating again.....

    While it is true that our galaxy can be considered as an object, it does not rotate as a single object. eg: Do you believe the spiral arms rotate as a fixed object?

    "In a sense..."

    How though, will this help Tim resove his question about centripetal force?

    We're not just discussing galaxies for fun, we're addressing Tim's confusion between gravitational force and centripetal force - that they're different.
