Cosmology · d = v / H₀
Hubble Distance
The distance to a galaxy from its recession velocity and the Hubble constant, by Hubble's law. Because the measured value of H₀ is itself contested — the Hubble tension — it is left as an input rather than fixed.
Distance100Mpc
Formula: d = v / H₀
Worked example
With the default inputs, hubble distance evaluates to 100 Mpc — 7000 km/s at H₀ = 70 → 100 Mpc. The validator recomputes this against the known value on every build, so the formula is checked, not asserted.
