Cosmic censorship of trans-Planckian field ranges in gravitational collapse
Cosmic censorship of trans-Planckian field ranges in gravitational collapse
A classical solution where the (scalar) field value moves by an ${\cal O}(1)$ range in Planck units is believed to signal the breakdown of Effective Field Theory (EFT). One heuristic argument for this is that such a field will have enough energy to be inside its own Schwarzschild radius, and …
