This is an absurd concept to imagine and makes no physical sense.

Indeed, when we say our model breaks down in a black hole or in the big bang, it means a singularity of infinity or dividing by zero. We have a model where the universe can expand faster than light, so we have to wait for whatever light comes our way, as we do for the sun and all the stars anyway. If that model is correct, and it is mainstream, then we just cannot know about the “now” we experience in local life. Everything we experience is in the past. Yet infinity is really useful in calculus, it validates the small step assumptions we make in differentials, partial differentials and integrals . There is no physical dilemma if we remember our inconsistent maths is just a model that works for most of the time. There does not have to be real infinity. But personally, a model including infinity still seems more satisfactory than magical beginnings and endings.

When we realize that patterns don't exist in the universe, they are a template that we hold to the universe to make sense of it, it all makes a lot more sense.
