The Hyperbolic Universe Does Not Need Dark Energy

Although the perspective for nearby objects in the hyperbolic space is very nearly identical to Euclidean space (i.e. the Universe locally is approximately flat consistent with local observations),

A time - luminosity correlation for Gamma - Ray Bursts in the X - rays

Gamma ray bursts (GRBs) have recently attracted much attention as a possible way to extend the Hubble diagram to very high redshift. However, the large scatter in their intrinsic properties prevents
