Questions to the coming talk of M. Albrow & A. Stebbins “A Cosmology with Time as a Closed Loop”
The questions below are focused on philosophical aspects of the topic.
- What are advantages, or attracting features, of the finite Universe?
- It is impossible to get rid of infinities completely: the number of thinkable mathematical structures is infinite. With any list of mathematical structures, I can add higher order nonlinear terms, derivatives, integrals, matrices. A few of these forms are structuring our world, while an infinite number of others do not participate at all. If every universe is finite, and there is only a finite number of universes, infinite number of mathematical structures cannot be employed even in the multiverse; there would be a fundamental segregation between the employed and unemployed forms. What or Who did determine this segregation in the world of forms? On which if any ground is it determined?
- Does the concept of a universe with its “time as a closed loop” implies also another time, which is external to that universe? Is it possible to say that this closed universe was born and will die in terms of this external time? What is the reference frame you are looking at this universe from?
- In the realm of the finite universe/multiverse, the number of possible stories, theories, pieces of art, lives is finite. They either appear and disappear circularly (eternal recurrence) or exist atemporally, similar to world lines in physics. Can life have any inspirational meaning in the finite realm, where even God, if exists, is doomed to watch the same finite movie again and again—forever?
