Near the end of the video there’s a reference to presentism and eternalism.

“Philosophical presentism is the view that neither the future nor the past exists. In some versions of presentism, the view is extended to timeless objects or ideas (such as numbers). According to presentism, events and entities that are wholly past or wholly future do not exist at all. Presentism contrasts with eternalism and the growing block theory of time, which hold that past events, like the Battle of Manzikert, and past entities, like Alexander the Great’s warhorse Bucephalus, really exist although not in the present. Eternalism extends to future events as well.” (Wikipedia)

Most of my reading (and many hours of meditation) makes me lean toward presentism. It’s always now. But –as suggested in the video– physicists insist the math argues for eternalism. And I’d kind of like for that to be “true” as well. Perhaps both can be true, depending on what time it is.
