Explore the emergence of four-dimensional metric space-time and early universe cosmology from the BFSS matrix model in this 45-minute conference talk delivered at the Workshop on "Large-N Matrix Models and Emergent Geometry" at the Erwin Schrödinger International Institute for Mathematics and Physics. Delve into how a high-temperature state of the BFSS matrix model leads to the emergence of a spatially flat and infinite space-time. Examine the role of thermal fluctuations in producing approximately scale-invariant spectra of cosmological perturbations and gravitational waves. Discover how this approach successfully explains current data without requiring a period of inflation, offering a fresh perspective on early universe cosmology.
