Is the Universe expanding at all ?
Well of course it is according to the current model however I followed a thread elsewhere where, I will call it, a "shrinking ruler model" was discussed.
So in that model everything is shrinking.
Now at first that sounds crazy but the only scientists in the discussion pointed out how such a model could fit the observations and in that the math worked better.
The difficulty with all of this stuff is you need to specialise in a field to understand what the current model really is saying. We can read papers but for anyone outside the field, any field really, one can ask are they educated enough to comment.
Personally I believe the current model is probably does not reflect reality only because of the way it is presented by journalists.
I do not understand inflation, without which the big bang fails, but there are folk who rightfully can say your education is insufficient for you to really grasp the concept.
All I can use is my "common sence" whatever that is to analyse the proposition of the big bang model that the Universe evolved from a very small hot dense region, some suggesting this region to be smaller than an atom, and that such region expanded or grew to a size equivalent to or greater than the observable universe in a split second.
I seem to recall Degrasse saying "in under a zillionth of a zillionth of a zillionth of a second...
Well I don't buy that but of course I am uneducated and don't understand things the way a professional does.
It smacks of creation and given a priest had a hand in developing the model I suspect observations fit a satisfactory philosophical model of cosmology.
And if you had spent your life studying the current big bang model it would be difficult to consider that any competing model could be valid...and if you did you would not say zip if you wanted to keep your name and career in tact.
The current model needs dark matter and dark energy such that we must accept a major part of the universe can not be observed or explained.
I wonder what models other intelligent species have come up with...
Now I am not being critical or cynical I don't know enough to enjoy either but I hope before I die they come up with a more " common sence" model.
I do like the steady state style model as it does not need expansion, or contraction dark energy or dark matter...or a creation point.
