Logically, it is impossible for space has boundary. If space has boundary, what is the other side?

However, logically, it is possible for space has limit. Whatever object reaches the limit, disappears.

… just as physical death is a limit of biological life, but not a boundary within your biological life.

In reality, the space has neither boundary nor limit, just as the surface of the Earth has neither boundary nor limit.
