Space and time are real and physical constraints. All things have both a place and time for them to exist. It cannot be otherwise.
Being present with the current space and time is called "staying in the moment" and "being mindful". It is a lauded ability.
That is, until people resent that we are not in the space and times all at once where they want us to be: Then it is called compartmentalization.
There is but one space and time we can occupy at any moment.
