ultrarelativistic

Accelerate to relativistic, then ultrarelativistic speeds

As you reach relativistic recession velocity with respect to the projector, your movie winds up in slow motion and and much redder, then a slide show, then an almost entirely still image in the ultrarelativistic limit.

My (2) is a problem for me because as one reaches the ultrarelativistic limit photons from the blackbody radiator will still ultimately reach you even if highly redshifted.

The Higgs vacuum is a medium that is both ultrarelativistic (pressure ≫ energy density) and ultra-quantum, being a Bose-Einstein condensate with almost all its particles in the same quantum state.

The degeneracy pressure of the object, however, is much larger, such that the star’s particles are ultrarelativistic and p = e/3, where e is the energy density and p is the pressure.

But on the other hand, ultrarelativistic objects don’t become black holes simply because they’re moving very fast.
