Mystery deepens over the universe expanding too fast | News


The fabric of space in the universe is expanding at more than 160,000 miles per hour, according to the most precise study ever of the composition and evolution of the cosmos.

The measurement has deepened one of the biggest mysteries in astrophysics because it is faster than the expansion rate predicted by scientific models, suggesting that scientists may need to rewrite their understanding of how the universe has evolved since the big bang.

Scientists leading the Pantheon+ analysis observed super-bright supernovae dotted round the universe. Just as a police car’s siren appears to drop in pitch as it moves away from you, the light from distant stars and galaxies becomes redder as they speed away. By analysing the extent of this “redshift”, astronomers can calculate
