All, Based on pointers that I have received from a number of people on the forum, I have been reading about the support that the time dilation of supernovae (type 1a) light curves provides to the standard model– thanks to all and a special thanks to GerogeJones. The material seems to fall into two categories – pro and against the relationship. The “pro” material seems (very honest, but) very selective in the fine-tuning of the model and the data used. On the other hand, the “against” material makes a number of references to people and models that I don’t have much faith in. On this basis, and respecting the views of people on the forum, can I ask your opinion on this subject: do you think that the time dilation of SN 1a light curves is good evidence of expansion? (Please note, I'm not asking about your views of expansion, just your views of the SN 1a light curve evidence.) Regards, Noel.
