Right! I saw Anton Petrov already released a video on the topic too, if you dig this then I highly recommend checking his YT channel to watch him break it all down.
Accuracy is near impossible when you are so far away. Everything is based on estimations or sophisticated tools that measure from multiple points and then average between but even then they can get hectic. As a matter of fact noone would be surprised if the reality almost didn’t match the measurements once you get next to them.
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.
