Webexplain the heaviest and earliest high-redshift galaxy can-didates detected by JWST given a string tension as low as G ˘10 9. Speci cally, we use EVS to compute the stellar mass distribution of the heaviest loop-seeded ha-los for redshift z>10 and z>16, which correspond to the inferred redshift of the two extreme JWST galaxies.

Scientists must move from direct observation to using observations in conjunction with a theory. The theory …
