Of course there is: 4D-space - usually infinite in all directions if one of
its roles is to explain the finite 3D-volume. (03)
And this notion is quite fantastic - so it should better make some equations
very elegant to be more justified than the spaghetti monster or the cellular
automaton. (04)

Even more fantastic :-) (06)

Would an eternal heat death count as nothingness? (08)

Wouldn't that mean endless repetition (if we only allow finite variation)?
I cannot see the difference to a finite one-shot. (010)

There can be a first state but no last state too. Isn't this what people
usually assume today? (012)
