For example, when a loft of bread expand, it takes up air space, so if the universe is expanding, it must be taking up space. What is this space that the universe is occupying?

The idea is that it isn't taking up anything at all, that all of the space dimensions are retained within the universe itself, and that the proverbial "outside" is a total nothing, in which there are not even any dimensions in which to exist in.
When dealing with this sort of thing you have to stop thinking in terms of three dimensions and the behaviour of normal objects, because the universe is neither "normal" nor an object. Much of this can only be visualised mathematically.

This question is a bit similar to the one, what was there before the Big Bang ?. Whatever expands, it expands inside an open and free space. It´s like inflating a balloon. Everything gets hotter inside a determined region of the space. It grows bigger but as Friedman said, according to one of their models, expansion will stop.

There wouldn't be space around the universe or it would be part of the universe. So it isn't taking up space, but it is expanding. In what? nothing. It isn't in anything.

Yes, the universe is expanding. However, it is not known what it is expanding in. We don't even know if our universe is part of an even larger universe. We have not been able to see out that far as of yet. But there is something out there that's holding it.

I unquestionably have 2 achieveable solutions. bodily logical answer: A vacuum. A vacuum is nothingness. The universe holds each and everything. The universe is increasing into what's exterior of it, however the universe holds each and everything. basically not something would nicely be exterior our universe, so nothingness it rather is! Fourth-dimensional headache answer: each and everything that hasn't befell yet and additionally what's going to on no account ensue. think of approximately it. Scientists have self assurance that factor is a length, yet in spite of the destiny holds relies upon on our movements and technically would not exist yet. If our universe's definition incorporates each and everything, then time must be factored in. The previous counts, yet what hasn't befell yet is exterior of that realm!

Space isn't expanding like you think.
The outer edges of space aren't growing. Galaxies are just moving further apart from each other. So the space in between galaxies is expanding, not the edges of the universe.

in space is life energy which allows life to form on planets .as everything moves and expands it simply pushes out whats in it way

Its not that kind of expansion.
Its called metric expansion. Look it up on wikipedia.
Its as though space itself had been originally tied up into a tight ball and is now slowly stretching out.
