The “afterlife” according to Einstein’s special relativity

Physicist and author Sabine Hossenfelder discusses the physics of dead grandmothers.

Description: Sabine Hossenfelder investigates life's big questions through the lens of physics, particularly Einstein's theory of special relativity. She highlights the relativity of simultaneity, which states that the notion of "now" is subjective and dependent on the observer.

This leads to the block universe concept, where past, present, and future all exist simultaneously, making the past just as real as the present.
