The universe is physically expanding. That is, the distance between galaxies is increasing. There is no space outside the universe. The universe creates space as it expands.

What's the universe expanding into?
Quoted from this website below
"I'll say this: if the universe is infinitely big, then the answer is simply that it isn't expanding into anything; instead, what is happening is that every region of the universe, every distance between every pair of galaxies, is being "stretched", but the overall size of the universe was infinitely big to begin with and continues to remain infinitely big as time goes on, so the universe's size doesn't change, and therefore it doesn't expand into anything."

Metric expansion of space
The metric expansion of space is a key part of science's current understanding of the universe, whereby spacetime itself is described by a metric which changes over time in such a way that the spatial dimensions appear to grow or stretch as the universe gets older. It explains how the universe expands in the Big Bang model, a feature of our universe supported by all cosmological experiments, astrophysics calculations, and measurements to date.
The expansion of space is conceptually different from other kinds of expansions and explosions that are seen in nature. Our understanding of the "fabric of the universe" (spacetime) requires that what we see normally as "space", "time", and "distance" are not absolutes, but are determined by a metric that can change. In the metric expansion of space, rather than objects in a fixed "space" moving apart into "emptiness", it is the space that contains the objects which is itself changing. It is as if without objects themselves moving, space is somehow "growing" in between them.
Because it is the metric defining distance that is changing rather than objects moving in space, this expansion (and the resultant movement apart of objects) is not restricted by the speed of light upper bound that results from special relativity.
Theory and observations suggest that very early in the history of the universe, there was an "inflationary" phase where this metric changed very rapidly, and that the remaining time-dependence of this metric is what we observe as the so-called Hubble expansion, the moving apart of all gravitationally unbound objects in the universe. The expanding universe is therefore a fundamental feature of the universe we inhabit - a universe fundamentally different from the static universe Albert Einstein first considered when he developed his gravitational theory.

The best question!The Truth, it is no Universe expansion!This it is the wrong interpretation of so called "red shift".Because the light-s energy decrease with distance,from W=hf,the frequency decrease.Now this it is interpreted like a Doppler effect,due to the so called expansion of the Universe.If the expansion it is true, this means an increase from one direction and decrease for another direction.Just if we suppose that the EARTH it is the center of the Universe,may be so.But taking into account the homogeneity of the space,this cannot be true.

god is feeling creative inspiration.There is still good left in this world even some bad people are changeable and the lord and his father are probably molding the future ,No one can believe there is life on other planets,but everyone agrees there would have higher intelligence,If that be the case maybe there waiting on the lord to fix us and finish prophecy,so the whole universe could live in peace,I think then space wont be much of a question,
this is probanly not the answer you were looking for but its just my opinion

Space itself is expanding, and the universe is infinite.

The universe is not actually expanding..It is our knowledge and understanding of it that is expanding.
