Relativity
Cosmological Redshift Calculator
Computes cosmological redshift, recession velocity, comoving distance, or the Hubble time from redshift z and the Hubble constant. Ideal for astronomy students and researchers analyzing galaxy observations.

Relativity
Relativistic Momentum Calculator
Compute the relativistic momentum p = γmv of a particle from its rest mass and velocity. Reduces to classical mv at low speeds but grows without bound as velocity approaches c.
