Re: SPACE EXPANSION(another space question)

Space isn't expanding into anything, there is no need for an
"embedding space" as it is known mathematically in order to have a
self-consistent spacetime with our laws of physics. This is usually a
bit hard to understand when one considers everyday phenomena which of
course occurs inside our space.

One could say spacetime can grow, in the sense that there could become
more of it between two points. But it doesn't grow into any outside
space, since it is space itself.

I hope this was comprehensible; the math is simple but hard to
explain (obvious in retrospect, as usual).
