Before the Bang: A Universe Born from Euclidean Space
![The universe is conceptualized as an emergent Lorentzian patch within a purely Riemannian four-dimensional space, where the conventional “big bang” is reinterpreted not as an origin, but as a hypersurface [latex]\Sigma_0[/latex] marking a transition in metric signature, and simplified geometries-dependent on a single spatial coordinate [latex]z[/latex]-ensure emergent spacetimes [latex]{\cal M}_{0\pm}[/latex] adhere to the Copernican principle and exhibit [latex](-,+,+,+)[/latex] signature in asymptotic regions.](https://arxiv.org/html/2602.02646v1/bbemergenceplot.jpeg)
