Inflation is a solid scientific theory, Alex. It is testable and can be falsified so it fits the definition of a scientific theory. It's testable through observation and can be falsified if a better idea comes along to displace it, but so far none has...but that doesn't make it wrong because it hasn't undergone the falsifiability premise.
Carl maybe I was hasty but I am not aware of the testability of the theory, no is there anything in the way of experimental observation as far as I know...not that I could know everything out there but from all I have read to me it seemed to fail the test of what constituted a scientific theory... still if there is something more I would love to read about it...for although I must sound sceptical etc I simply dislike the way some notions claim the status of theory.
AND how could it be falisified? really the custom surrounding theory and falisibiliy means in effect if I claim a theory it stands until someone can prove it wrong... in these areas how can you really prove anything ..we are dealing with stuff that happened some 13.5 approx billion years ago and I suspect all eye witnesses have long passed on...

"160 billion ly would be a small fraction of that size"...
Is there any most widely accepted opinion on the size of the Universe... 160 is the largest guess I have read ...
