Does constantly expanding entail something is infinite?

Not necessarily. While expanding can indicate growth or increase, it does not necessarily mean that something is infinite. Expansion can occur within finite boundaries or limits. It ultimately depends on the specific context or situation in which the expansion is occurring.

Can you divide infinite?

In mathematics, it is not possible to divide by infinity in the traditional sense. Division by zero, as well as division by infinity, is considered undefined in standard arithmetic because it leads to mathematical inconsistencies. Infinity is not a specific number or value that can be divided like finite numbers. However, in some branches of mathematics and theoretical physics, specialized concepts such as infinite series or limits are used to approach questions involving infinity.
