Episode notes
Early Nanotechnology Research
- As a high school student, Monika Schleier-Smith interned at MITRE Corporation, focusing on nanotechnology research.
- This early exposure led to a patent and the establishment of a lab based on her brainstormed ideas.
Standard Model's Gravity Gap
- The Standard Model of particle physics, while successful, omits gravity, lacking a particle (like a 'graviton') to mediate it.
- This omission creates a challenge in unifying quantum mechanics, which governs the small, with gravity, relevant to massive objects.
Emergent Gravity from Entanglement
- The concept of emergent phenomena, like color arising from atomic configurations, suggests gravity could similarly emerge.
- Quantum entanglement, where information exists in correlations between particles, might be the underlying mechanism.
