I've actually applied for some course material from the Open University now, going to do a physics course, something I wish I'd done when I went to uni. Instead of getting drunk, dropping out and working for an insurance company, lol
Andy, yes mate, there always be on such a contentious issue and this is due to there being conflicting models and until sufficient data is accumulated to either bolster or contradict each and every model, then we will have this situation as I am sure you are aware.
The universe is expanding, that much is sure, it was the realisation of this that gave rise to the big bang theory but the main divide among cosmologists seems to be whether there is enough matter in the universe to bring it back together or not with I think the majority going for the oscillating universe - big bang, big crunch - big bang and so on.
I don't pretend to be well versed in such matters but I do have a 'working' knowledge that isn't derived from being able to 'copy and paste'
I did read some time back that some recent data had suggested that some galaxies were in fact accelerating away from the genesis point with this really putting the cat among the pigeons because the oscillating universe bods would have expected (if anything) for it to be slowing down.
As I said, I am certainly no expert, but even in my little brain it did make me think of possible reasons why in fact it should be accelerating.
Was something providing the required force for acceleration from outside the universe or was it a repulsive force from within, with the latter obviously seeming the more reasonable.
Now that is the event horizon of my knowledge on such matters and I can comment no more but I can still be intrigued by the subject matter ... I love things I don't understand but only things that blow my little mind when I eventually understand them
I mean, who understands women?
Certainly not me, they definitely have a quantum based psychology with us men being more Newtonian biased with direct linkage to the testosterone molecule.
This fact alone predetermines us to being soooo predictable, whereas females ??? ... now there's a can of worms
Good Luck !
