If I have this right, the distance determined by light curves [supernova as standard candles], differs from distance determined by redshift [hubbles law] by a significant amount.
This difference I believe was the reason why dark energy was postulated and currently accepted.

Thanks

Dark energy and matter are fabulist"s wishes.
IMHO H. C. Andersen had better real physical base.
