Problems with an Infinite Universe

comment on eggs last statement(6)..
any point in space should also have a hubble sphere equal in size to our own given that: the same amount of time has passed at all points in space and photon decoupling should have occured at nearly the same time at all points in space (barring the last few photon collisions since that approx. time). wouldnt it be an easy assumption to make, then, that each one of these spheres is its own 'universe' (visible universe) (and some of these spheres surrounding around our own will intersect with ours, kind of like bubbles with shells that cross over each other). just an idea..

why has entropy killed the idea of an infinite universe?
