How “Spacetime” is Created in the Universe.

The speaker proposes that spacetime emerges from quantum interactions, suggesting that particles and their wave functions create the spacetime around them. This perspective challenges traditional views of spacetime as a pre-existing entity, offering explanations for phenomena like the EPR paradox and Schrodinger's cat, and suggesting that the universe is constantly 'becoming' through these interactions.

Spacetime Emergence

• 00:00:00 The speaker postulates that spacetime isn't a pre-existing entity but rather emerges from quantum interactions between particles. They propose that when a particle's wave function collapses, it creates not only the particle itself but also the spacetime surrounding it. This means that the empty space is a product of quantum events.

Quantum Interactions & Spacetime

• 00:01:04 The speaker argues that quantum interactions between particles, like photons and gravitons, precede spacetime. They suggest that these interactions shape the universe and our understanding of space and time. This is different from the perspective where spacetime is a backdrop for the events and particles.

Becoming and Time Asymmetry

• 00:06:34 The speaker introduces the concept of 'becoming' as the fundamental asymmetry of time. They suggest that the universe is constantly evolving and creating spacetime, not just a static entity existing in the past, present, and future. This perspective implies that spacetime is not fixed, and we are part of this ongoing 'becoming'.

Schrödinger's Cat & EPR

• 00:03:32 The speaker applies the 'becoming' concept to understand Schrodinger's cat and the EPR paradox. They suggest that before a measurement, there is no spacetime for a superposed cat or entangled particles. When a measurement occurs, spacetime 'fills in' the gap, effectively creating a history of the cat's state or the particle's positions.

Attraction & Repulsion

• 00:07:31 The speaker suggests that interactions happening 'beyond now,' outside of spacetime, determine attraction and repulsion. When quantum interactions collapse, resulting in 'becoming,' they give rise to the relative positions of particles, which then manifest as gravitational or electromagnetic forces. This interaction determines whether particles attract or repel each other.
