Mechanical Resolution of the Hubble Tension: Calculating the Yield Duration

Key Points

• To define the duration required for vacuum re-hardening after a metric slip event.
• Calculated the ratio of vacuum viscosity to Planck-normalized yield stress.
• Matched re-hardening duration with the decay profile of a specific Fermi-GBM event.
• Established a defined temporal interval for vacuum re-hardening.
• Presented a 'Mechanical Signature' for metric instabilities linked to astrophysical events.
