Diese durch Gravitationslinsen erzeugten Supernovae könnten die Hubble-Spannung lösen

This is a fascinating approach to the problem, but it explicitly creates a new one *if* it works…

Cepheid measurements constrain us to 73.4 km/s/Mpc (CI [0.99, -1.22]). That doesn’t overlap the CMB method, 68.3km/s/Mpc (CI ±1.5), *at all*.

If the value we observe via gravitational lensing is right in the middle of those two, it doesn’t harmonize them; the question simply becomes why every *other* 1A supernova gives us a different answer. Effectively we’ll potentially have *three* mutually incompatible answers rather than two.
