relatively new to physics/astrophysics/astronomy/cosmology, and can't get enough of it..
as such, I've started reading as much as i can on the topic, and have one lingering question;
when we talk about 'the universe', are we talking about our 'observable universe'? that is, the universe we can measure, from it's beginning singularity to it's ever expanding growth?
if so, is the reason as simple as we need a finite universe, or a model, in order to apply our equations to, base assumptions/theories around etc?
and finally, if that is the case, what is the bigger universe picture? a bunch of disconnected universes going through their respective cycles? if so, how does that work? do they overlap?
Thanks guys
