Can Spacetime be Torn and Ripped?

Can spacetime be tear and rip?

nobody knows what spacetime is like at microscopic quantum scale
and nobody knows what dark energy is

theorists who want to envisage the ripping of space
can use a model of space that can be ripped
and a hypothetical very mean version of dark energy
whose pressure-density relation keeps changing with time
so it gets more and more expansive

(there is no evidence that dark energy is like this, it is only
a mathematical possibility)

so such theorists, who want the speculative fun of thinking
of how spacetime could experience a shredding Big Rip,
can cook up speculative scenario like that
they make spacetime so it can be ripped and
they make dark energy have an increasing expansiveness
and eventually after a long time there is this very
lovely end of the universe where nothing can hold together
people fly apart and then atoms fly apart and then the pieces
of atoms fly apart and so on.

what's the use?

I don't find that kind of set up scenario speculation so exciting myself
because it seems more exciting when people actually try to
develop a notion of what dark energy really is
and what the geometry of spacetime is down at the quantum level.
If they get a grasp of that then the scenarios will get more fun
because of having more realism.

There is currently no evidence or theoretical framework that suggests spacetime can be torn or ripped. Spacetime is a fundamental concept in physics that describes the fabric of the universe, and it is believed to be continuous and smooth. While there are theories that suggest spacetime can be distorted or warped, such as in the presence of massive objects like black holes, there is no indication that it can be torn or ripped. Additionally, the laws of physics, such as the conservation of energy and momentum, would not allow for such a phenomenon to occur.
