The statement you’ve made touches on some fundamental ideas related to the nature of time and space in physics and philosophy. Let’s break down its implications:

1. Simultaneity and Relativity: The idea that “everything happens all at once but in different places” is somewhat related to the concept of simultaneity in the theory of relativity. In Einstein’s theory of special relativity, events that are simultaneous in one frame of reference may not be simultaneous in another. This suggests that the notion of “now” is relative and depends on your perspective or frame of reference.
2. Space-Time: In the theory of general relativity, space and time are intertwined in what is known as space-time. Events in the universe are described as occurring at specific points in space-time. This implies that everything that has ever happened or will happen is already “located” in space-time, and events occur at different points within this continuum.
3. Change and Persistence: On the other hand, the idea that things happen “over time in the same place” highlights the concept of change and persistence. In our everyday experience, we perceive events unfolding sequentially, and we see objects enduring through time. This concept aligns with the common-sense notion of time as a linear progression.
4. Philosophical Considerations: Philosophically, your statement raises questions about the nature of time, causality, and the relationship between the past, present, and future. It invites contemplation on whether the past, present, and future exist simultaneously in some sense or whether they are purely sequential.

In summary, your statement touches on the complex and often paradoxical nature of time and space. It highlights the interplay between different perspectives, such as the relative nature of simultaneity and the idea of events existing within space-time, while also acknowledging our everyday experience of time as a linear progression. These ideas have fascinated physicists and philosophers for centuries, and they continue to be subjects of exploration and debate.
