    Expanding Universe
Click For Summary
The discussion centers on the concept of the expanding universe and what it is expanding into. It asserts that the universe is not expanding into anything; rather, it is creating more space over time, akin to a balloon inflating without needing an external space. The idea of a finite universe suggests it wraps around itself, allowing for a return to the starting point if one were to travel far enough. Participants debate the nature of dimensions, with some asserting the definitions of one-dimensional and two-dimensional spaces while others argue about the implications of these definitions in mathematical versus physical contexts. Ultimately, the conversation highlights the complexities of understanding dimensions and the nature of space in relation to the universe's expansion.

Lets go back to the original question
If the universe is expanding then what is it expanding in to?
Good question
The universe is not expanding like an explosion that we see on earth.
The space between the components of the universe is increasing.
This is hard to understand but this is what scientist tells us.
Yes space is being created out of what we call nothing.
