frozon

From froze +‎ -on. From being a particle that is so heavy, having Planck energy / Planck mass, that its self-gravitation results in a relativistic gravitational field so extreme that gravitational time dilation slows time to a stop, freezing time.

frozon (plural frozons)

1. (physics) A proposed type of theoretical particle, a Planck-scale particle with Planck energy, whose field fluctuations are frozen in time due to self-gravitational time dilation.
