Ekpyrotic Universe: How Bouncing Branes Could Replace Cosmic Inflation
Key Takeaways
- Ekpyrotic theory replaces the Big Bang singularity with a collision of two branes in higher-dimensional space.
- The model is rooted in string theory and avoids singularities by having a finite, physical bounce.
- It solves the horizon and flatness problems through a slow contraction phase before the bounce.
- Observational tests include CMB polarization, non-Gaussianity, and gravitational wave signatures.
