Sabine Hossenfelder studies life's big questions through the prism of physics, particularly Einstein's theory of special relativity. It highlights the relativity of simultaneity, which affirms that the notion of “now” is subjective and dependent on the observer. This leads to the concept of a block universe, where the past, present, and future all exist simultaneously, making the past as real as the present.
Hossenfelder also points out that the fundamental laws of nature preserve information rather than destroy it. Even if information about a deceased person disperses, it remains part of the universe. This idea of timeless existence, derived from the study of fundamental physics, offers profound spiritual insights that can be difficult to internalize in our daily lives. As a result, Hossenfelder encourages people to trust the scientific method and accept the profound implications of these findings, which could reshape our understanding of life and existence.
As a physicist, Hossenfelder trusts the knowledge gained through the scientific method and recognizes the challenge of integrating this deep knowledge into our everyday experiences. By contemplating these profound concepts, we can potentially expand our understanding of reality and our place in it.
