The Variable Entropy Spacetime (VES) model treats spacetime as an informational system, where information entropy and regeneration mechanisms play a central role. Unlike classical black holes, VES predicts no singularity at the center — instead, there exists an informational core that causes partial reflection of gravitational waves. This short note presents the first concrete testable prediction: the echo delay time of gravitational wave echoes detectable by LIGO, Virgo, and KAGRA.
