I think The original poster has some problems understanding this article.. it doesnt "prove" that the big bang never happened. Certainly the conclusions call the current cosmology into question, but all it proves is that certain predicted phenomena dont exist in all cases. (specifically shadows in microwave background).

One study like this doesnt yet disprove the big bang cosmology. It does show us how little we really know about the larger universe however, and current cosmology is likely to be very incomplete.

For myself I'm not big suporter of a single universal "Big Bang". The extent of the universe may be much more vast than such a theory predicts. it seems at least concievable that there have been many big bangs in many regions of the universe, each creating galactic super-clusters or even larger structures we know nothing about.

Whether or not the amount of matter in the universe is actually infinite I dont know; certainly there is an amount vast enough that it cant be easily understood. The universe may not be exactly infinite, but it may be indefinite.

The interesting thing about cosmology is that it is a wide-open field, and we can expect many more discoveries and controversies for a long time to come, as methods of seeing farther and with more precision are developed.
