Current physics is speeding toward a breaking point, as astronomers confirm that the Hubble tension in new data.

New measurements using gravitational lensing suggest the universe’s current expansion rate does not agree with signals from ...

Scientists are testing a novel way to measure cosmic expansion using time delays in gravitationally lensed quasars. Their ...

New gravitational lensing measurements by the TDCOSMO Collaboration support the Hubble Tension, confirming differences between Early and Late Universe Hubble Constant values using updated ...

A team of astronomers using a variety of ground and space-based telescopes including the W. M. Keck Observatory on Maunakea, ...

For much of the twentieth century, scientists expected the expanding universe to slow over time. The opposite turned out to be true. Space is stretching faster today than in the past, and the precise ...

There is an important and unresolved tension in cosmology regarding the rate at which the universe is expanding, and ...

Astronomers are closing in on a result so statistically secure that, in their language, it borders on certainty: a 99.9999999 ...

For the past decade, scientists have been trying to get to the bottom of what seemed like a major inconsistency in the universe. The universe expands over time, but how fast it’s expanding seemed to ...

Scientists have made a new calculation of the speed at which the universe is expanding, using the data taken by the powerful new James Webb Space Telescope on multiple galaxies. Webb’s image of one ...

His latest book, Discordance, fits into the class of conventional popular cosmology, in so far that it is an account of how our present understanding of the Universe has emerged. But it is also, with ...

The following is an extract from our Lost in Space-Time newsletter. Each month, we hand over the keyboard to a physicist or mathematician to tell you about fascinating ideas from their corner of the ...
