Researchers from the University of Waterloo have proposed a new method to measure the Hubble constant that could help resolve ...

Given sufficient redshift (or, equivalently, time) resolution effected by the redshift slicing, one might just find that the Hubble diagram exhibits jumps in the redshift distance relation, which ...

one might just find that the Hubble diagram exhibits jumps in the redshift distance relation, which would be very revealing." More information: Richard Lieu, Are dark matter and dark energy ...

The universe’s expansion may be driven by “transient temporal singularities”—rapid, invisible bursts of energy—rather than dark matter or dark energy, according to new research that challenges the ...

Abstract: Graph Edit Distance (GED) is a classical graph similarity metric. Since exact GED computation is NP-hard, existing GNN-based methods try to approximate GED in polynomial time. However, they ...
