There are two competing theories that try to define whether our space is bound.
Theory of Limited Space
The theory of limited space states that there is a limited amount of space available, and once the subject expands to fill all the available space, it will not be able expand any more.
Theory of Unlimited Space
The theory of unlimited space states that there is an unlimited amount of space available. As a result, and expanding subject can continue to expand indefinitely, not limited by the space constraint, but its expansion my still be limited by factors other than space availability.
The Third Theory of Space
There is a third little known theory that states that space is neither limited nor unlimited. One consequence of this theory is that an expanding object will not be permitted to expand indefinitely due to space constraints, but the amount of remaining available space is undefined.
Some scientists believe that all three theories are wrong, which leads to the fourth theory of space.
Fourth Theory of Space
The forth theory of space stats that space is both limited an unlimited. Although intuitively this theory sounds paradoxical, in reality it is sound and consistent.
P.S., sorry Albert, I didn’t have time – though I had the space – to incorporate time in the space theories.
