Monica Schreier Smith wants to create spacetime from scratch in her lab

Space and time may not be fundamental. Instead, according to holographic principles, they emerge from something deeper, just as 3D holograms emerge from a flat surface. According to this principle, space-time, and by extension gravity, arise from quantum entanglement.
With that in mind, monica schreier smith The physicist at Stanford University in California (pictured above) is trying to create space-time from scratch. Her approach simulates her 2D holographic boundaries around the universe. According to holographic principles, this is enough to encode all the information that describes the inner universe. This “holographic duality” states that spacetime and the lower dimensional boundaries in which it appears are equivalent.
In essence, Schreier-Smith’s methodology involves tabletop experiments that have the potential to reveal how holographic principles contribute to phenomena down to the smallest scale phenomena on which space-time appears. I am.
Lyndie Chiou: What is the experimental setup?
Monica Schreier Smith: The tools I work with are laser-cooled atoms. The atoms are isolated in a vacuum chamber and a laser is used to lower them to very low temperatures, several millionths of a degree above absolute zero. We fix them where we need them. This essentially provides a starting point for creating very well-controlled models of quantum systems.
How can we tell if particles are entangled?
We have been exploring the idea of holographic duality. [by trapping] Atoms between two mirrors forming an optical cavity. The beauty of this optical cavity is that any atom can interact with any other atom. Photons can travel between these atoms and…
