Are static models totally static?

  1. Nov 21, 2012 #1
    Hi, I appreciate the basics if static models, but I'm wondering just how static they are. I understand there is no expansion, but is there any element of evolution? (For example, colliding galaxies, collapsing dust clouds, etc.)

    Regards,

    Noel.

    Static doesn't mean no movement. Everything is moving and react to gravitation and quantum effects. No big bang, no expansion, just there.

    Thanks Jedisshrfu. That's what I figured, but couldn't find confirmation in any of the literature.

    Regards,

    What static model are you referring to? There are steady state models such as Hoyles (now discredited model) and more mdoern steady sate models such as steady state eternal inflation. A new static model was pubslihsed a few months ago:
    http://arxiv.org/abs/1205.5550
    but I believe all of these models allow for observations of an expanding universe and galaxies colliding etc but perhaps thats now what you are referring to.

    Thanks for the reply skydivephil. A lot of the arxiv items that I have read lately refer simply "static models" in various contexts. I was pretty sure that this (generally) did not mean completely unchanging ... but I could not find any clarification.

    Regards,

    Noel.
