My take: There is no "into" without the concept of "space". The universe is space (and time). Thus it's not expanding into anything as there is no space outs

  Universe is expanding in the sense that the "amount" of space is growing: there was so much space between those two stars and a year later there is more of it. Where does this space come from? And why is it only space that's expanding, why not time?

    > why not time? Every second we have another second* of time in most of the universe. * May be less time near large amounts of mass.
