Estimations and theories keep getting modified as and when we use more advanced techniques for various studies. Just today I was watching a video on youtube (Anton Petrov’s channel) about how the data from JWST is making it necessary for scientists to come up with different theories for the evolution of galaxies. The present accepted theories were supported by data from the Hubble telescope, but the higher resolution data from the JWST is making it clear that the theories may need to be reviewed.
