Philosophy 201 Guidelines
Cogito ergo sum
Here in the Philosophy forum we will talk about all the "why" questions. We'll have conversations about the way in which philosophy and theology and religion interact with each other. Metaphysics, ontology, origins, truth? They're all fair game so jump right in and have some fun! But remember...play nice!

It certainly is a contradiction to say that all stars are dead and all stars are not dead - in the same universe.

The block universe exists "all at once" when viewed from the outside. That is not a contradiction. Any more than in my gif file, all dots and circles exist "at once" when viewed in an editor. Your objection is nonsense.
